BATON ROUGE, Louisiana – As Tropical Storm Francine barreled toward the Louisiana coast Tuesday, residents were making final preparations: filling sandbags, buying gasoline and stocking up on supplies to weather the storm, which is predicted to turn into a hurricane before it makes landfall.

Residents, especially in southern Louisiana, have a 24-hour window to “batten down the hatches,” Louisiana Governor Jeff Landry said Tuesday afternoon. Meteorologists said Francine is predicted to make landfall Wednesday afternoon or evening as a Category 2 hurricane with winds of 95 to 100 mph (155 to 175 km/h) and powerful storm surge.

Roxanne Riley, 42, who has lived in New Orleans her entire life, stocked up on water, snacks and other groceries from a Walmart and said she planned to remain at a member of the family's house on high ground to avoid flooding, but was prepared to evacuate if things got worse.

“It's always very frustrating when a storm comes,” Riley said. “I'm just going to make sure my car is ready to go in case I have to leave tomorrow. I'll keep checking and see what it looks like.”

According to the National Hurricane Center, a hurricane warning was in effect along the Louisiana coast from Cameron eastward to Grand Isle, about 50 miles south of New Orleans. A storm surge warning prolonged from the Mississippi-Alabama border to the Alabama-Florida border. Such a warning means there may be a risk of life-threatening flooding.

In the event that the storm makes landfall, Landry advises residents to remain put and never exit onto the streets, thereby hindering emergency responders or staff repairing power lines.

As of late Tuesday afternoon, Francine was still a tropical storm with maximum sustained winds of 65 mph (100 km/h), in keeping with the hurricane center. The system was positioned about 360 miles (580 kilometers) southwest of Morgan City, Louisiana, and moving northeast at 10 mph (17 km/h).

The storm is moving over extremely warm Gulf waters, that are strengthening it. The water temperature is about 88 degrees Fahrenheit where Francine is positioned, said Brian McNoldy, senior research associate on the University of Miami's Rosenstiel School of Marine, Atmospheric and Earth Science.

“The average ocean heat content over the entire Gulf is the highest ever recorded for this time,” McNoldy wrote on his blog.

However, the system encountered barely drier air because it moved north, which could have reduced the storm's intensity, forecasters said. But the storm remains to be expected to achieve hurricane strength.

In downtown New Orleans, cars and trucks lined up for several blocks to gather sandbags from the car parking zone of the local YMCA, whose executive director Erika Mann said Tuesday that 1,000 bags of sand had already been distributed by volunteers.

“I'm glad these people from the community came out,” Mann said. “What we're doing in New Orleans is a wonderful achievement. We're resilient and we come together to help when we need each other.”

One of the residents collecting sandbags was Wayne Grant, 33, who moved to New Orleans last 12 months and was nervous about his first possible hurricane in town. The low-lying rental apartment he shares along with his partner had already flooded in a storm the 12 months before and he didn't need to take any probabilities this time.

“It was like a slap in the face. Since then, we've been trying to keep up with the weather,” Grant said. “We've invested a lot in the place, even though we don't own it.”

A little bit greater than three years after Hurricane Ida destroyed his home in Dulac Township, Terrebonne Parish, on the Louisiana coast — and a couple of month after he finished rebuilding — Coy Verdin was preparing for one more hurricane.

“We had to gut the whole house,” he recalled in a telephone interview, rattling off an inventory of jobs from memory, including a brand new roof and latest windows.

Verdin, 55, has seriously considered moving further inland, away from his home on nearby Bayou Grand Caillou, where he makes his living, but plans to remain there after reconstruction, he said.

“As long as I can. But it's getting tough,” he said. He was preparing to go north to go to Francine and his daughter in Thibodaux, a couple of 50-minute drive away. “I don't want to go too far away so I can come back and check on my house.”

Landry said the Louisiana National Guard is being deployed to communities that might be affected by Francine and is supplied with food, water, nearly 400 high-water vehicles, about 100 boats and 50 helicopters to answer the storm and conduct possible search and rescue operations.

Francine is the sixth named storm of the Atlantic hurricane season. It carries the specter of life-threatening storm surge in addition to damaging, life-threatening hurricane-force winds, said Brad Reinhart, a senior hurricane specialist on the hurricane center.

There can also be a probability of 4 to eight inches of rain, with as much as 12 inches possible in much of Louisiana and Mississippi by Friday morning, Reinhart said. These heavy rains could also cause significant flash flooding and concrete flooding.

Meteorologists said Francine's storm surge along the Louisiana coast could reach heights of as much as 10 feet (3 meters) between Cameron and Port Fourchon and in Vermilion Bay.

“There is a risk of very dangerous, life-threatening flooding,” said Michael Brennan, director of the hurricane center, adding that “dangerous, destructive winds could also reach quite far inland.”

He said landfall would likely occur somewhere between Sabine Pass – on the Texas-Louisiana border – and Morgan City, Louisiana, about 220 miles (350 kilometers) to the east.

TOKYO – A severe storm battered southern Japan with torrential rain and fierce winds on Thursday, killing at the very least three people because it moved slowly across the archipelago and raising fears that it could cause flooding, landslides and extensive damage.

Tropical Storm Shanshan made landfall on the southern island of Kyushu on Thursday morning as a robust typhoon and regularly weakened afterward. However, it remains to be forecast to bring strong winds, high waves and significant rainfall to most parts of the country, especially Kyushu.

In parts of Miyazaki Prefecture on Kyushu, about 60 centimeters of rain fell, the rivers swelled and there was a threat of flooding. Japan Meteorological Agency This 24-hour total is higher than the typical rainfall for the entire of August, it said.

By late Thursday afternoon, the storm was moving north at 15 km/h and its wind speed had weakened to 108 km/h. It was “no longer a strong typhoon,” the agency said.

As the disaster threat within the Kyushu region subsided later Thursday, Shanshan began to dump heavy rains on the neighboring island of Shikoku.

The storm swept through downtown Miyazaki on Kyushu, flattening trees, overturning cars in parking lots and smashing the windows of some buildings. The prefectural disaster response group said about 50 buildings were damaged.

Public broadcaster NHK showed a swollen river in the favored hot spring town of Yufu in Oita Prefecture, north of Miyazaki, and muddy water splashing against a bridge.

More than 70 people were injured in Kyushu, most of them in Miyazaki and Kagoshima. Some were injured because they were thrown to the bottom by the storm as they made their strategy to emergency shelters, the hearth and disaster management agency said.

According to Kyushu Electric Power Co., about 168,000 households across Kyushu were without power, most of them in Kagoshima Prefecture.

According to prefectural reports, around 20,000 people sought shelter in urban community centers, school gymnasiums and other facilities across Kyushu.

Before the storm's arrival, heavy rains triggered a landslide that buried a house within the central city of Gamagori, killing three residents and injuring two others, the town's disaster management agency said. On the southern island of Amami, which Shanshan passes by, one person was injured when a gust of wind knocked him over while riding a motorbike, the hearth department said.

Weather and government officials fear major damage because the storm slowly moves northeast across the Japanese archipelago over the following few days, threatening further flooding and landslides.

Disaster mitigation minister Yoshifumi Matsumura said Shanshan could cause “unprecedented” winds, high waves, storm surges and heavy rains. At a task force meeting on Wednesday, he urged people, especially the elderly, to not hesitate and seek shelter if there are safety concerns.

Hundreds of domestic flights between cities and islands within the southwest were canceled on Thursday, and high-speed trains and a few local trains were suspended. As the storm moved northeast, similar measures were taken in parts of the predominant island of Honshu, where heavy rain was falling. In the Kyushu region, postal and delivery services were suspended, and supermarkets and other shops are to shut.

HONOLULU (AP) — Tropical Storm Hone approached Hawaii's southern edges Saturday with gusty winds and heavy rains, and will cause flooding and storm damage on the Big Island over the weekend and increase the danger of wildfires on the drier sides of the islands.

The National Weather Service has issued a tropical storm warning for Hawaii County, which incorporates your complete Big Island, in addition to a red flag warning for the leeward sides of all islands.

Hone, which implies “sweet and gentle” in Hawaiian, had peak sustained sustained winds of 65 mph (105 kph) early Saturday. It will likely strengthen right into a Category 1 hurricane because it passes near or south of the Big Island Saturday night into Sunday morning, in keeping with the National Hurricane Center in Miami.

Hawaii's tourism authority told travelers it was still secure to go to the islands, but advisable people postpone outdoor activities.

“We do not advise visitors to cancel their trips,” the agency said in a press release.

Hone's center was about 260 miles (415 kilometers) east-southeast of Hilo and 470 miles (755 kilometers) east-southeast of Honolulu on Saturday morning.

The east and southeast of the Big Island could see 4 to 10 inches of rain. The island could experience sustained winds of 20 to 40 mph (32 to 64 km/h) and gusts of as much as 60 mph (97 km/h).

Dry air to the north of the storm will bring dry spells to the archipelago on Saturday and, together with strong winds, will increase the danger of wildfires. Much of the state is already experiencing unusual dryness or drought, in keeping with the U.S. Drought Monitor.

The weather service's “Red Flag” warning is in effect from 10 a.m. to six p.m. Saturday. It is issued when warm temperatures, very low humidity and stronger winds mix to extend the hearth danger. The winds are expected to be strongest where they blow from higher elevations, over headlands and thru passes, the hurricane center warned.

The situation is paying homage to the deadly wildfires on Maui last yr, which were fueled by hurricane-force winds. But the danger of wildfires on Hone is lower, said Laura Farris, a meteorologist with the Honolulu Weather Service.

The August 8, 2023, fire that burned the historic town of Lahaina was the worst wildfire within the United States in over a century. Strong winds, fueled partly by a hurricane that passed through southern Hawaii, fueled the flames that killed 102 people. Dry, overgrown grass and drought contributed to the hearth's spread.

The reason behind the Lahaina fire remains to be under investigation, but it surely is feasible that it was began by bare power lines and leaning power poles that were toppled by the high winds.

Behind Hone, Category 2 Hurricane Gilma moved westward across the Pacific. However, it is anticipated to weaken over cooler waters in the approaching days because it encounters drier air. It is anticipated to change into a tropical depression by Wednesday. Gilma could bring rain to Hawaii, but it surely will not be yet clear how much, Farris said.

When tropical meteorologists Satellite imagesthey often see subtle cloud formations that indicate that something more sinister is brewing.

The first signs of a possible hurricane might be detected days before the storm develops. Thin, outward-radiating cirrus clouds, the looks of low-lying clouds with curved bands, and a drop in barometric pressure are all indicators.

These early clues are crucial for predicting the onset of a potentially catastrophic hurricane.

I’m a Professor of Meteorology at Penn State and my research group are using satellites and computer models to enhance the forecasting of tropical weather systems. With a very severe storm season forecast for the Atlantic in 2024, it’s more essential than ever to have the option to acknowledge these early signals and supply early warning. Here's what meteorologists are in search of.

Conditions for a hurricane

Hurricanes typically begin as atmospheric tropical wavesLow pressure areas related to clusters of thunderstorms. As these tropical waves move westward over the tropical oceans, a few of them can turn into hurricanes.

The formation of a hurricane is dependent upon several specific conditions:

Distance from the equator: Tropical cyclones often form at the least 5 degrees from the equator. This is since the Coriolis forcewhich is crucial for the initial rotation of the cyclone system, is weaker near the equator. The Coriolis force is attributable to the rotation of the earth, which causes moving air to rotate and swirl.

Warm sea surface temperatures: The sea surface temperature must at the least 26.5 degrees Celsius (approx. 80 Fahrenheit) for the formation of a hurricane. The warm water provides energy that drives the storm because the storm absorbs heat and moisture from the ocean.

Atmospheric instability and humidity: For tropical cyclones to form, the atmosphere should be unstable. This implies that warm surface air rises and stays warmer than the encompassing air, allowing it to proceed to rise and form thunderstorms. There must even be quite a lot of moisture, as dry air can evaporate clouds and weaken the upward motion in thunderstorms. These aspects are essential for the event of thunderstorm clusters throughout the tropical waves.

Low vertical wind shear: Strong vertical wind shear can tear apart a developing hurricane. Vertical wind shear is a change in wind direction or speed at different altitudes. It disrupts the formation and growth of a storm and makes it difficult for a hurricane to maintain its vortex aligned.

Early predictions require greater than satellites

Detecting the early stages in a hurricane's life cycle could be very difficult because there usually are not many surface stations and weather balloons that might provide detailed atmospheric information over the open ocean.

Once a storm forms, the National Oceanic and Atmospheric Administration's hurricane-hunting planes often fly through it, taking measurements and dropping sensors to get more data. But that's impossible for each thin cloud, especially if the developing system is much from the coast.

One of an important tools meteorologists currently use to predict the early formation of hurricanes is satellite imagery, which provides real-time data on cloud patterns, sea surface temperatures, and other atmospheric conditions. GOES satellites The satellites operated by NOAA help meteorologists track the event of hurricanes with unprecedented clarity. These satellites can capture images at multiple wavelengths, allowing meteorologists to investigate different features of the storm, akin to Cloud formation, precipitation And Lightning activity.

However, satellite observations alone don’t provide meteorologists with enough information to predict which tropical waves are more likely to turn into hurricanes.

To improve forecast accuracy, our research group has developed Methods for integrating real-time satellite dataincluding humidity and cloud patterns, into computer forecast models. This process, often known as data assimilation, enables a more accurate and consistent representation of atmospheric conditions. This allows meteorologists to learn from significantly improved forecasting capabilities, especially in predicting the formation and path of hurricanes.

We are currently Collaboration with NOAA These techniques can be refined and used on a bigger scale to enhance hurricane forecasts and supply earlier warnings in order that the population has more time to arrange.

As people in North America and the Caribbean prepare for what is anticipated to be a very intense hurricane season in 2024, the necessity for accurate early storm forecasts is larger than ever.

Tropical Storm Debby was move so slowlyThe Olympic athletes could have escaped it when it moved across the Southeast in early August 2024. This gave the rain time to flood towns and farms in large parts of Florida, Georgia and the Carolinas. More than a foot of rain had fallen in some areas by early August 7, 2024, with more rainy days There and within the northeast there’s a risk of flooding.

Matthew Barlowa climate scientist at UMass Lowell, explains how storms like Debby pick up a lot moisture, what could cause them to slow or stop, and what climate change has to do with it.

What causes hurricanes to stop?

Hurricanes are controlled by the weather systems they interact with, including other storms moving across the United States and the Bermuda High over the Atlantic.

A hurricane may crawl because there are not any weather systems close enough to drag the hurricane along, or because there’s a high pressure system north of the hurricane that blocks its forward movement.

In this case High pressure area over the western USA slowed Debby's progress, and the Bermuda High – a big, clockwise wind circulation that normally moves up the East Coast – was not close enough to matter.

Something similar happened with the remnants of Hurricane Harvey in 2017, one in every of the best-known examples of a stalled hurricane. High pressure over the USA blocked his forward movement and made him fall greater than 50 inches of rain in parts of Texas.

Slower-moving storms have more time to dump rain over the identical area, which may dramatically increase the chance of flooding, because the Southeast is currently experiencing with Debby.

How can Debby carry a lot rain?

The surface temperatures of the Atlantic Ocean and the Gulf of Mexico were much warmer than average for the past 12 months. At the moment there’s a very wide area with exceptionally warm There, sea surface temperatures are very high, which suggests strong evaporation.

In addition, the air is warmer than average and warm air can hold far more moisture.

So more evaporation from a hotter ocean pumps more moisture into warmer air, which may hold more. This “more and more” has led to a whole lot of moisture within the air over this massive area, from the Gulf of Mexico to the East Coast, and that's the realm Debby is moving through. The storm is pulling in a unprecedented amount of moisture from all directions – it's the right environment for very heavy rainfall.

The warm, moist air can also be spreading to the East Coast, so heavy rains and flooding are forecast for the Mid-Atlantic region and possibly the Northeast because the storm moves north and interacts with other weather systems.

Debby can also be move near the coast. Because there’s more water within the air over the ocean, the storm can last more since it has a reservoir of fuel. Had Debby moved further inland, the storm would have died down more quickly.

What impact does climate change have on tropical cyclones?

Human-induced climate change is Warming of the ocean and atmosphere. This warming is essentially resulting from the Combustion of fossil fuelswhich Emit greenhouse gases that trap heat near the Earth’s surface.

The combination of warmer ocean and warmer atmosphere can lead to higher rainfall amounts and more rapidly intensifying storms.

There can also be evidence that hurricanes within the USA Slowing down their forward movement and that this may increasingly be related to climate change, but this connection is just not yet sufficiently understood.

Without a rapid reduction in fossil fuel emissions, these storms and their rainfall will proceed to extend. The excellent news is that humanity knows methods to reduce emissionsand there are initial efforts to maneuver the world on this direction.

What does Debby have in store for the Northeast?

Tropical Storm Debby is predicted will proceed to maneuver slowly over the southern United States or simply off the coast for several days, with a high risk of excessive rainfall and parts of the Carolinas specifically are vulnerable to catastrophic flooding.

Significant rainfall can also be expected in parts of the Mid-Atlantic and the Northeast. The area from Philadelphia to New York City is already under flood warnings ahead of the storm, partly resulting from a frontal boundary where tropical moisture can accumulate.

Once Debby moves through and interacts with other systems, its motion is forecast to speed up and move toward Atlantic Canada, leaving massive flood damage in its wake.

Hurricane Beryl was the last Atlantic storm to rapidly intensify. It quickly developed from a tropical storm into the strongest June Atlantic hurricane on record. meet the Grenadine Islands with wind speeds of 240 km/h and a destructive storm surge on July 1, 2024, after which intensified further into the basin first Category 5 storm on record.

Beryl was still a robust Category 4 hurricane on July 3, when its eye wall roamed the coast of Jamaica and was heading towards the Cayman Islands. A hurricane warning was in effect for giant parts of the Mexican Yucatan Peninsula.

The damage attributable to Beryl especially on Carriacou and Petite Martinique, was extensivesaid Grenada's Prime Minister Dickon Mitchell at a press conference. “Within half an hour, Carriacou was razed to the ground.”

Beryl's strength and rapid intensification were unusual for a storm so early within the season. This 12 months it is especially alarming as meteorologists predicted a exceptionally energetic hurricane season within the Atlantic.

Rapidly intensifying storms can put coastal communities at great risk and leave lasting scars. In 2022, for instance, Hurricane Ian devastated parts of Florida after the storm rapidly intensified. To this present day, residents are still recovering from the results.

What causes rapid intensification of hurricanes, and has climate change made rapid intensification more likely?

I research hurricanesincluding their formation and their intensification, and am a part of a U.S. Office of Naval Research initiative rapid intensification. I also work with scientists on the National Atmospheric and Oceanic Administration to research data collected by reconnaissance aircraft that fly into hurricanes. Here's what we're learning.

How did Hurricane Beryl intensify so quickly?

Rapid intensification occurs when a hurricane's intensity increases by at the very least 35 miles per hour over a 24-hour period. Beryl far exceeded that threshold, increasing from tropical storm strength (70 miles per hour) to major hurricane strength (130 miles per hour) over a 24-hour period.

A Key ingredient for rapid intensification is warm water. The water temperature have to be above 27 degrees Celsius (80 degrees Fahrenheit) and extend to greater than 45 meters below the surface. This reservoir of warm water provides the energy needed to drive a hurricane.

Scientists measure this energy reservoir as the warmth content of the ocean. The heat content of the ocean before Beryl was already extraordinarily high in comparison with previous years. The heat content of the oceans within the tropical Atlantic doesn’t normally reach such high levels until early September, when the hurricane season typically reaches its peak.

Beryl is a storm more typical of the height of hurricane season than of June, and its rapid intensification and strength are likely because of the unusually warm waters.

In addition to the high heat content of the oceans, studies have shown that other environmental aspects typically in order that rapid intensification can happen. These include:

My research has shown that when this mix of things is present, a hurricane more efficient use of energy It gathers from the ocean to power its winds, relatively than having to fight against drier, cooler air moving in from the storm's surroundings. The process known as ventilation.

At the identical time, more air is drawn inward toward the middle, rapidly increasing the strength of the vortex, just like how a figure skater pulls their arms inward to create spins. Rapid amplification is comparable to a figure skater pulling each arms quickly and shut to the body.

Does climate change affect the likelihood of rapid intensification?

As the oceans warm with climate change and the ocean heat content increases, it is affordable to assume that rapid intensification may change into more common. There is evidence that rapid intensification of storms has change into more common within the Atlantic.

In addition, the intensity peaks of hurricanes have increased on average by 25 to 30% when comparing hurricane data between 1971–1990 and 2001–2020. This has led to faster intensification events comparable to Beryl.

This faster intensification is because of environmental aspects: warm waters, low vertical wind shear, and a moist atmosphere that occur more incessantly, giving hurricanes more opportunity to accentuate rapidly.

The excellent news for anyone living in a region vulnerable to hurricanes is that Hurricane forecast models are recuperating in predicting rapid intensification prematurely, in order that they can provide residents and emergency managers more advance warning of potential threats. NOAA’s latest hurricane model, the hurricane evaluation and forecast systemguarantees further improvement in hurricane forecasts, and artificial intelligence could Providing additional tools to predict rapid intensification.

My research has shown that when this mixture of things is present, a hurricane more efficient use of energy It gathers from the ocean to power its winds, somewhat than having to fight against drier, cooler air moving in from the storm's surroundings. The process is named ventilation.

At the identical time, more air is drawn inward toward the middle, rapidly increasing the strength of the vortex, much like how a figure skater pulls their arms inward to create spins. Rapid amplification is comparable to a figure skater pulling each arms quickly and shut to the body.

Does climate change affect the likelihood of rapid intensification?

As the oceans warm with climate change and the ocean heat content increases, it is affordable to assume that rapid intensification may turn out to be more common. There is evidence that rapid intensification of storms has turn out to be more common within the Atlantic.

In addition, the intensity peaks of hurricanes have increased on average by 25 to 30% when comparing hurricane data between 1971–1990 and 2001–2020. This has led to faster intensification events similar to Beryl.

This faster intensification is on account of environmental aspects: warm waters, low vertical wind shear, and a moist atmosphere that occur more regularly, giving hurricanes more opportunity to accentuate rapidly.

The excellent news for anyone living in a region susceptible to hurricanes is that Hurricane forecast models are convalescing in predicting rapid intensification upfront, in order that they can provide residents and emergency managers more advance warning of potential threats. NOAA’s latest hurricane model, the hurricane evaluation and forecast systemguarantees further improvement in hurricane forecasts, and artificial intelligence could Providing additional tools to predict rapid intensification.

Tropical Storm Alberto, the primary named storm of the 2024 hurricane season, formed within the Gulf of Mexico Wednesday morning and is moving toward the coast of Mexico.

The storm is positioned 320 miles southeast of Brownsville, Texas, moving west-southwest at 9 mph and has maximum sustained winds of 40 mph.

Meteorologists are also monitoring two other potential systems that might hit the north Florida coast on Friday. Alberto is predicted to strengthen barely overnight before making landfall south of the U.S.-Mexico border early Thursday morning. Once inland, the storm is predicted to quickly weaken and dissipate over Mexico by Thursday night.
