Hurricane Laura pounded the Gulf Coast with ferocious wind and torrential rain. It unleashed a wall of seawater that could push 40 miles inland as the Category 4 storm roared ashore Thursday in Louisiana near the Texas border. At least one person was killed.

The National Hurricane Center said Laura slammed the coast with winds of 150 mph (241 kph) at 1 a.m. CDT near Cameron, a 400-person community about 30 miles (48 kilometers) east of the Texas border. Forecasters had warned that the storm surge would be “unsurvivable” and the damage “catastrophic.”

They predicted a storm surge of 15 to 20 feet in Port Arthur, Texas, and a stretch of Louisiana including Lake Charles, a city of 80,000 people on Lake Calcasieu.

Laura battered a tall building in Lake Charles, blowing out windows as glass and debris flew to the ground. Police spotted a floating casino that came unmoored and hit a bridge. But hours after the hurricane made landfall, the wind and rain were still blowing too hard for authorities to check for survivors.

Gov. John Bel Edwards reported Louisiana’s first fatality — a 14-year-old girl who died when a tree fell on her home in Leesville.

Hundreds of thousands of people were ordered to evacuate ahead of the hurricane, but not everyone fled from the area, which was devastated by Hurricane Rita in 2005.

“There are some people still in town, and people are calling … but there ain’t no way to get to them,” Tony Guillory, president of the Calcasieu Parish Police Jury, said over the phone from a Lake Charles government building that was shaking from the storm.

Guillory said he hoped the stranded people could be rescued later in the day, but he feared that blocked roads, downed power lines and floodwaters could get in the way.

“We know anyone that stayed that close to the coast, we’ve got to pray for them, because looking at the storm surge, there would be little chance of survival,” Louisiana Lt. Gov. Billy Nungesser told ABC’s Good Morning America.

More than 600,000 homes and businesses were without power in the two states, according to the website PowerOutage.Us, which tracks utility reports.

Laura hit the U.S. after killing nearly two dozen people on the island of Hispaniola, including 20 in Haiti and three in the Dominican Republic, where it knocked out power and caused intense flooding.

It was the seventh named storm to strike the U.S. this year, setting a new record for U.S. landfalls by the end of August. The old record was six in 1886 and 1916, according to Colorado State University hurricane researcher Phil Klotzbach.
