(AP) Hurricane Laura made landfall in southwestern Louisiana as a ferocious Category 4 monster early Thursday, swamping a low-lying coast with ocean water that forecasters said could be 20 feet deep and unsurvivable. The National Hurricane Center said the storm, which intensified rapidly Wednesday before plowing into land, came ashore at 1 a.m. CDT near Cameron, a 400-person community about 30 miles (48 kilometers) east of the Texas border. “Potentially catastrophic impacts will continue,” forecasters said. Winds gusted above hurricane force to 128 mph (206 kph) while Laura's northern eyewall moved onshore over Cameron Parish. Forecasters said even stronger winds were possible that could rip apart buildings, level trees and toss vehicles like toys. Authorities had implored coastal residents of Texas and Louisiana to evacuate, but not everyone did before howling winds began buffeting trees back and forth in an area that was devastated by Rita in 2005. “There are some people still in town and people are calling the building but there ain’t no way to get to them,” Tony Guillory, president of the Calcasieu Parish Police Jury, said over the phone as he hunkered down in a Lake Charles government building that was shaking from the storm. Guillory said he hopes those stranded can be rescued later Thursday but he fears that blocked roads, downed power lines and flooding could delay that process. Video and photos on social media showed torrents of rain flying sideways past street lights in Lake Charles, and streets covered with water closer to the coast. A sudden storm surge knocked over cameras meant to capture the hurricane’s effects. With hours of violent weather ahead, officials said the extent of destruction likely wouldn't be clear until daybreak, when search and rescue missions will begin. Drawing energy from the warm Gulf of Mexico, the system arrived early Thursday during high tide as the most powerful hurricane to strike the U.S. so far this year. “It looks like it’s in full beast mode, which is not what you want to see if you’re in its way," University of Miami hurricane researcher Brian McNoldy said. Maximum sustained winds increased to 150 mph (241 kph) before nightfall, and forecasters said up to 18 inches (46 centimeters) of rain could fall. Forecasters issued a string of tornado warnings as the storm pushed on to land, but there were no immediate reports of damage. More than 200,000 homes and businesses were without power in Texas and Louisiana. Earlier Wednesday, winds picked up as shoppers rushed into a grocery store in low-lying Delcambre. Trent Savoie, 31, said he was staying put. “With four kids and 100 farm animals, it’s just hard to move out,” he said. Texas Gov. Greg Abbott and Louisiana Gov. John Bel Edwards fretted that the dire predictions were not resonating despite authorities putting more than 500,000 coastal residents under mandatory evacuation orders. Officials said at least 150 people refused pleas to leave and planned to weather the storm in everything from elevated homes to recreational vehicles in coastal Cameron Parish, which could be completely covered by ocean water. “It’s a very sad situation,” said Ashley Buller, assistant director of emergency preparedness. “We did everything we could to encourage them to leave.” Edwards activated the state’s entire National Guard. In Lake Charles, Guard members drove school buses around neighborhoods, offering to pick up families. Across the state line in Port Arthur, Texas, few stragglers boarded evacuation buses, and city officials announced that two C-130 transport planes offered the last chance to leave. A Category 4 hurricane can render wide areas uninhabitable for weeks or months and knock out power for just as long. The threat of such devastation posed a new disaster-relief challenge for a government already straining under the coronavirus pandemic. The parts of Louisiana that were under evacuation orders included areas turning up high rates of positive COVID-19 tests. The National Hurricane Center kept raising its estimate of Laura’s storm surge, from 10 feet (3 meters) just days ago to twice that size — a height that forecasters said would be especially deadly.
