Temperatures expected to surpass record highs in southern U.S. What to know in Louisiana

Yahoo03-07-2025
Temperatures have been high across the south-central U.S. and forecasts predict that temperatures will climb above historical averages this week by between five and 15 degrees Fahrenheit.
Persistent hot air is pushing northward from Mexico and expanding across parts of Texas, New Mexico, Oklahoma, Southern Kansas, Arkansas and Louisiana.
These regions are currently encapsulated in a 'heat dome,' which refers to an expansive and stagnant zone of high pressure that causes climbing temperatures and limited cloud cover because of sinking air, according to AccuWeather.
Louisiana is experiencing the effects of a 'heat dome,' as temperatures reach dangerous and potentially life-threatening highs. This heat dome is produced by an area of high atmospheric pressure, which causes heat and humidity to become trapped and lead to to sweltering conditions.
Forecasters expect that, as the jet stream moves slightly northward and eastward in the next days, the heat will proliferate into a portion of the Plains, Mississippi Valley and Southeast, according to AccuWeather.
Since the heat dome is expected to persist, with the hottest temperatures shifting slightly eastward, it's likely that Louisiana will continue to experience extreme heat caused by the heat dome.
Louisiana residents are advised to take precautions to stay safe during this heat wave by staying hydrated, seeking shade and avoid strenuous activities during the hottest parts of the day.

Evacuations, state of emergency in North Carolina as Hurricane Erin looms

Mandatory evacuations are underway in North Carolina's Outer Banks as Hurricane Erin sends powerful waves toward the East Coast, with AccuWeather meteorologists warning of life-threatening flooding, road washouts and coastal erosion. The Outer Banks are expected to be the area of the United States hit the hardest by Erin, with local officials declaring a State of Emergency for Dare County and evacuations for Hatteras Island. Residents have been told to evacuate by 8 a.m. EDT Tuesday. A tropical storm watch and a storm surge watch have been issued along the coast of North Carolina due to the rising threats from Erin. The watches advise people to "plan for life-threatening storm surge flooding." The watches will likely be upgraded to warnings as Erin draws near. "Now is the time to make final preparations, secure property, evacuate with all personal belongings and follow instructions from your property management company," Dare County officials said in a statement. People who stay behind to ride out the storm may be cut off from the mainland for several days as Highway 12, the main road in the area, is likely to be impassable. Waves are predicted to be between 10 and 20 feet along the Outer Banks with the pounding waves to persist most of the week. "Roads will likely be impassable under several feet of water, and vehicles will likely be submerged," officials said. "Large dangerous waves will likely inundate and destroy protective dune structures. Severe flooding will likely extend inland where there is vulnerable or no protective dune structure flooding homes and businesses with some structural damage possible." Elsewhere along the Atlantic coast, beaches are announcing closures due to the risk of rip currents from Hurricane Erin. Wildwood, New Jersey, is one of the beaches that is closed to swimmers, saying on Facebook, "To ensure the safety of everyone, including those who may be called to perform a rescue, please stay on the sand until the storm passes later this week." Puerto Rico flooded as Erin tracks nearby Parts of Puerto Rico were underwater in the wake of Erin, which unleashed heavy rain across the island over the weekend. The eye of the major hurricane stayed north of Puerto Rico, but it tracked close enough for tropical downpours to flood regions of the island. Nearly 150,000 electric customers were without power due to impacts of the hurricane, according to The Associated Press, but that number has gradually declined as weather conditions improve. San Juan measured 2.9 inches of rain since late last week, but some remote areas picked up as much as 8 inches. Cleanup is underway, but residents are advised that the far-reaching influence of Erin will continue to produce life-threatening rip currents in the coming days.

Climate change is increasing the risk of rapidly intensifying storms. Hurricane Erin is the latest example.

Hurricane Erin strengthened back into a Category 4 behemoth over the weekend, the latest shift in what has been a remarkably fast-changing storm. The hurricane's behavior in recent days makes it one of the fastest-strengthening Atlantic hurricanes on record, and yet another indication that climate change is increasing the risk of rapidly intensifying storms. Erin became the first hurricane of this year's Atlantic season on Friday and exploded in strength from a Category 1 into a Category 5 storm in a little over 24 hours. Even after it weakened and re-strengthened into a Category 4 storm, Erin's jaw-dropping transformation ranks it among the five fastest storms to grow from Category 1 to Category 5. The hurricane is expected to grow larger and strengthen even more on Monday as it passes east of the Bahamas, according to the National Hurricane Center's latest advisory. Heavy rainfall is forecasted for parts of Hispaniola on Monday, and for Turks and Caicos and parts of the southeast and Central Bahamas through Tuesday. But it's the storm's 'rapid intensification' that has experts taking note. Rapid intensification describes an increase in sustained wind speeds of at least 35 mph over a 24-hour period, according to the National Hurricane Center. Erin's maximum sustained wind speed increased around 75 mph in 24 hours, from Friday morning into Saturday. Climate change is increasing the risk of rapidly intensifying storms, primarily due to warmer-than-usual sea surface temperatures and high levels of moisture in the atmosphere — key ingredients needed for storms to gather strength. Erin's journey near the Bahamas on Monday will take it over warm waters hovering in the mid-80 degree Fahrenheit range, which could help it intensify further. A warmer atmosphere as a result of global warming also holds more moisture, which enables storms to gather strength and dump more rainfall over land. A 2023 study published in the journal Scientific Reports found that tropical cyclones in the Atlantic Ocean were around 29% more likely to undergo rapid intensification from 2001 to 2020, compared to 1971 to 1990. Indeed, rapid intensification has been well documented in recent years. In 2019, Hurricane Dorian's peak winds increased from 150 mph to 185 mph in nine hours. Hurricane Ian in 2022 underwent two rounds of rapid intensification before it made landfall in Florida. Last year, Hurricane Milton's maximum sustained wind speed increased by an astonishing 90 mph in roughly 25 hours. Other recent examples of rapid intensification include Hurricane Harvey in 2017, Hurricane Laura in 2020, Hurricane Ida in 2021 and Hurricane Idalia in 2023. Still, the process of rapid intensification remains difficult to forecast. Scientists know that warm sea surface temperatures, moist air and favorable atmospheric conditions are necessary pieces of the puzzle, but understanding how it will happen for specific storms — and when — will require more research. In the coming days, the National Hurricane Center said Erin will move between Bermuda and the east coast of the United States. Though the storm is not expected to make a direct hit with land, the hurricane will generate swells, life-threatening surf and rip currents for the Bahamas, Bermuda, the eastern seaboard of the U.S. and Atlantic Canada.

How Hurricane Erin Will Impact the U.S.

Hurricane Erin is ripping through the Atlantic Ocean, passing just east of the Turks and Caicos and southeast Bahamas on Aug. 18 and 19, bringing coastal flooding to the islands. While the category 4 storm is not expected to make landfall on the U.S. east coast, it will have an impact nonetheless. Dangerous high surf and rip currents are expected from Florida to New England throughout the week. 'It looks like it's going to stay offshore through its entire lifetime, but because it's so large in size, it is going to be bringing impacts,' says Alex DaSilva, AccuWeather's lead hurricane expert. The hurricane saw an 'exceptionally rare' rapid intensification—growing from a tropical storm to a category 5 hurricane in 24 hours on Saturday. (The storm has since been downgraded to a category 4.) Climate change is increasing the frequency and intensity of hurricanes—and the number of extreme rapid intensification events have increased significantly in the past three decades. As of Monday morning, evacuation orders are in place for the Outer Banks region of North Carolina, where DaSilva says they might see waves of up to 15 feet. 'That's just waves coming into the coast,' he says. 'There's going to be major beach erosion and major coastal flooding issues on the Outer Banks in the middle of the week.' And though other regions might not face evacuations, the storm will create unsafe conditions at beaches across the East Coast as many beachgoers might be looking to squeeze in one last trip before school starts. 'Anybody on the East Coast from Miami all the way up to Maine needs to be aware that this week, the rip current risk is going to be extremely high and very dangerous,' says DaSilva. 'So even if you're in Long Island or Massachusetts or Maine—far away from the storm—when you're at the beaches it's going to be very dangerous.' Keep an eye out for no swimming signs at the beach, and make sure to listen to any lifeguard instructions. Rip currents are expected to last into next week—at least until Saturday. 'It's going to be a very dangerous week for beach weather,' says DaSilva. 'We don't want people to venture out there thinking it doesn't look that bad and get hurt because rip currents are nothing to mess with.'
