storm surges in Louisiana and Texas
Hurricane Laura continued to strengthen late Wednesday as it approached the Louisiana coastline, reaching a wind speed just shy of that of a Category 5 storm.
Forecasters say Laura could cause an ‘unsurvivable’ storm surge.
A Category 5 hurricane has never hit the coast of that state, CNN meteorologist Brandon Miller said. Hurricane Katrina had that strength in the Gulf but was downgraded before it made landfall in 2005.
Laura was moving over the Gulf of Mexico with maximum sustained winds of 150 mph, about 90 miles south of Lake Charles, Louisiana, and it could strengthen even more before making landfall near the Texas border, forecast for shortly after midnight local time.
With top winds of 150 mph, Laura is a high-end Category 4, only 7 mph below a Category 5 hurricane.
"Sustained tropical-storm-force winds and steady heavy rains (are) beginning to spread onshore the central Louisiana coast," the NHC said in an update Wednesday evening.
Water levels along the Louisiana coast were rising rapidly Wednesday evening as Category 4 Hurricane Laura threatened potentially devastating winds and "unsurvivable storm surge" to the border with Texas, the National Hurricane Center said.
Building up in front of Laura as it pushed through the Gulf was a surge of water that could reach as high as 15 to 20 feet in places, the center said, and extend up to 40 miles inland. The center warned that “large and destructive waves will cause catastrophic damage” to a roughly 150-mile portion of the Gulf Coast from Sea Rim State Park in Texas to Intracoastal City, La.
