Laura was downgraded to a tropical storm Thursday afternoon, after making landfall in Louisiana near the Texas border overnight as a Category 4 hurricane with maximum sustained winds of 150 mph.
That made Laura the most intense hurricane to make landfall in Louisiana in 164 years, since what was called the Last Island Storm in 1856. It is also tied for the strongest hurricane on record to ever hit the state. The storm surge topped 10 feet in parts of western Louisiana, far less than the maximum prediction of 15-20 feet. The highest water levels were seen to the right of the storm's center, over a wildlife refuge area, sparing the more densely populated areas in the region.
East Texas was able to avoid the worst of the storm, which was expected to weaken to a tropical depression overnight. At least six deaths in Louisiana have been attributed to Laura, including a 14-year-old girl from Vernon Parish.

Some Lake Charles residents who didn't evacuate now asking for help
LAKE CHARLES, La. — An official in a southwestern Louisiana parish says some people who did not evacuate are now requesting assistance.
Tony Guillory, president of Calcasieu Parish’s police jury, was hunkering down in a Lake Charles government building that was shaking from the storm early Thursday as phones were ringing.
“People are calling the building but there ain’t no way to get to them,” he said over the phone.

Laura has made landfall — what's next?
Louisiana governor closes part of Interstate 10
BATON ROUGE, La. — Louisiana Gov. John Bel Edwards said the state is closing Interstate 10 from around the Atchafalaya Bridge outside of Lafayette all the way into part of Texas, because several stretches within that area are expected to flood.
In a radio interview Wednesday night, Edwards talked of the “apocalyptic” language that meteorologists have used for the storm. “The language I’ve heard from the National Weather Service I’ve never heard before ... They’re sending the strongest possible message about how serious this storm is,” he said.
He talked specifically about concerns in Cameron Parish.
“When people built back after Rita, they routinely built back to 15 feet,” Edwards said. He noted those structures would be overwhelmed.
Edwards said search and rescue efforts will begin Thursday as soon as it’s safe enough for officials to go out into floodwaters.
