(NEW YORK) — Laura is hitting the Gulf Coast as a Category 2 hurricane with an “unsurvivable storm surge” expected in some areas, according to the National Hurricane Center.

“Unsurvivable storm surge with large and destructive waves will cause catastrophic damage from Sea Rim State Park, Texas, to Intracoastal City, Louisiana, including Calcasieu and Sabine Lakes,” the NHC said in a statement. “This surge could penetrate up to 30 miles inland from the immediate coastline. Only a few hours remain to protect life and property and all actions should be rushed to completion.”

Parts of eastern Texas and western Louisiana are forecast to see “catastrophic wind damage,” especially in places where the storm’s eyewall makes landfall early Thursday morning, the NHC said. Residents in affected areas are being instructed to evacuate and are urged to brace for “widespread damaging wind gusts” that will spread well inland across parts of those areas.

Here’s how the news is developing Thursday. All times Eastern:

9:25 a.m.: 508,109 customers without power in Louisiana and Texas

Power outages across Louisiana and Texas climbed to more than half a million customers on Thursday morning, as Hurricane Laura battered the coastline.

By 8:15 a.m. ET, there were 403,921 customers without power in Louisiana and 104,188 customers without power in Texas.

8:30 a.m.: ‘Those evacuations did save lives,’ Texas governor says

Texas Gov. Greg Abbott said no deaths have been reported in the state so far, which he noted was “really premature” as Hurricane Laura “continues to sweep through Texas in an unprecedented fashion.”

“Because it’s not just where the surge came in, but going up north and Jasper and Center Texas, all the way up to Marshall, Texas,” Abbott told ABC News’ Good Morning America. “So in northeast Texas, a hurricane is going through there for as far as I know the first time ever, so this is truly unprecedented.”

As many as 10,000 people have evacuated their homes in Texas, particularly in the southeastern area of the state along the coast and near the border with Louisiana, according to Abbott.

“It could have been a lifesaver,” he said. “That may be one reason why we don’t have any reports of loss of life yet. We still don’t know how many people may be injured. We will be learning that here shortly as the sun rises, and we have search and rescue teams in place to make sure that everybody is going to be safe.”

Abbott emphasized the importance of early evacuations ahead of a powerful hurricane like Laura.

“Those evacuations did save lives,” he said.

7:56 a.m.: Dozens of families didn’t evacuate, Louisiana lieutenant governor says

Louisiana Lt. Gov. Billy Nungesser said he’s heard of dozens of families who didn’t heed evacuation orders and decided to stay behind.

“Some people just don’t want to leave their belongings,” Nungesser told ABC News in an interview Thursday on ABC News’ Good Morning America. “It’s hard to get them to leave sometimes.”

Nungesser recalled his own decision to ride out Hurricane Katrina back in 2005, as the large Category 5 storm battered New Orleans.

“I know what I went through,” he said. “Not a good decision.”

Emergency crews will be dispatched to check on residents and survey the damage “as soon as it’s safe” to do so, according to the lieutenant governor.

“We’re hopeful that we don’t find people that didn’t make it,” he added.

7:18 a.m.: Woman describes moment storm rips roof off home as family hides under kitchen table

Ashley Thompson and her family decided to ride out the hurricane at their home in Louisiana, where many residents were ordered to evacuate.

“We thought we were safe. We had generators, we had windows boarded up,” Thompson said in telephone interview Thursday on ABC News’ Good Morning America.

But the storm ended up being “much worse” than they thought, she said. The winds picked up in the early morning hours around 2 a.m., as Hurricane Laura made landfall on Louisiana’s shores as a Category 4.

“We got our family in our home under the kitchen table,” she said. “After being under the kitchen table for about five minutes, we lost our roof.”

Thompson and her family ran from their home and broke into a nearby house that was empty and under construction. They took cover there with other families in the neighborhood who were also riding out the storm.

Thompson said there are felled trees and power lines in their neighborhood and they hope first responders will come as soon as weather conditions improve.

“We are safe and everyone is unhurt,” she said. “But when they become available and people start moving, we will need help.”

Despite the storm being a Category 3 now, the National Hurricane Center said Laura can still cause an “unsurvivable storm surge with large and destructive waves.” The damage, according to the NHC, will cause “catastrophic damage” and floodwaters are not expected to recede for several days.

Hurricane-force winds are expected to continue Thursday morning with catastrophic wind damage expected nears Laura’s eyewall, according to the NHC.

“Hurricane-force winds and widespread damaging wind gusts will continue to spread well inland into portions of extreme eastern Texas and western Louisiana through the day,” NHC said in its 5 a.m. advisory.

“The eyewall of Laura is moving onshore over southwest Louisiana. Take cover now,” the National Hurricane Center said in its 1 a.m. forecast. “Treat these imminent extreme winds as if a tornado was approaching and move immediately to the safe room in your shelter. Take action now to protect your life.”
