Hurricane Laura, now a Category 4 storm, is barreling in the direction of the coasts of Louisiana and Texas with winds of 140 miles per hour and the menace of an “unsurvivable” storm surge with massive and damaging waves that “will cause catastrophic damage,” based on the National Hurricane Center.
Laura’s storm surge could attain as excessive as 15 to 20 ft in some areas and journey so far as 30 miles inland. The storm might also carry flash flooding and tornadoes on land.
“The water is already coming up,” stated National Hurricane Center Director Ken Graham warned on Wednesday. “If you’re told to leave, you need to do it now because what happens is the water comes in early and you start cutting off your evacuation routes.”
Storm surge is water degree rise brought on by hurricane winds and low stress pushing water onto shore, and is made worse when hitting a coastal space throughout excessive tide. Depending on when the storm strikes, Laura could coincide with excessive tide.
A Category Four hurricane brings particularly robust winds of between 130 and 156 miles per hour that make storm surge worse and extra damaging.
Flooding has began
The topography of south Louisiana, which is within the direct path of Laura, is particularly weak to a robust surge. Much of the land between the coast and the town of Lake Charles is marshland and there are networks of rivers and lakes that run into the Gulf of Mexico.
A powerful storm surge will push all that water inland, exacerbating flooding and damaging properties. According to the NHC, the storm surge will arrive forward of Laura’s middle late Wednesday, which suggests if folks delay evacuating, the roads could already be inundated.
“The storm surge flooding is starting now in Louisiana,” Louisiana Gov. John Bel Edwards stated in a information convention Wednesday afternoon. “It’s well ahead of the storm. It will just get worse over the next day or so.”

The surge could attain as much as 30 miles inland from the shoreline between Sea Rim State Park, Texas, and Intracoastal City, Louisiana and could elevate water ranges as excessive as 20 ft in elements of Cameron Parish, Louisiana, based on the NHC.
Forecasters stated the surge will seemingly attain Interstate 10, a main route between south Louisiana and southeastern Texas that was inundated throughout Hurricane Harvey in 2017.
“To think that there would be a wall of water over two stories high coming on shore is very difficult for most to conceive, but that is what is going to happen,” stated National Weather Service meteorologist Benjamin Schott at a information convention.
“The word ‘unsurvivable’ is not one that we like to use, and it’s one that I’ve never used before,” Schott stated.
The NHC warned on Wednesday morning that “only a few hours remain to protect life and property” as Laura makes its means towards the coasts of Texas and Louisiana.
Climate change has resulted in hotter atmospheric and ocean temperatures in addition to sea degree rise, which mixed have pushed extra intense and quickly creating hurricanes with extra harmful surges.
This yr’s hurricane season is on monitor to grow to be one of the worst in recorded historical past as sea floor temperatures proceed to rise within the tropical Atlantic Ocean and Caribbean Sea, in accordance to forecasters on the National Oceanic and Atmospheric Administration’s Climate Prediction Center.
