Heavy rains and winds battered Louisiana Thursday morning as a weakening Hurricane Laura roared northward, threatening to spread further damage well inland after slamming the Lake Charles area and causing at least four deaths.

The historic Hurricane Laura made landfall early Thursday in Cameron, about 45 miles south of Lake Charles, as a dangerous Category 4 hurricane with sustained winds of 150 mph. It's since weakened to a tropical storm.

"As we wake up today, everyone must remember that the threat  Laura poses to Louisiana is ongoing," Lousiana Gov. John Bel Edwards tweeted Thursday morning. "Stay home, continue to heed the warnings and instructions of local officials and monitor your local news to stay informed."

The first fatality from the storm in Lousiana was a 14-year-old girl who died when a tree fell on her home, according to the governor.

"We do expect that there could be more fatalities," Edward's Deputy Chief of Staff Christina Stephens tweeted.

Stephens said the girl died in the town of Leesville, located in Vernon Parish.

"That's not along the coast. Hurricane Laura's winds have been very strong as the storm has come ashore and through Louisiana," she tweeted.

At an afternoon news conference, Edwards said at least three other deaths in the state have been linked to falling trees from the storm

"I'm asking that we all lift up these families in prayer," he said.

As the storm roared into Louisiana, a 133 mph gust and an 85 mph sustained wind were measured in Lake Charles.

A 127 mph wind gust was measured at Calcasieu Pass, La., and a sustained wind of 93 mph was measured around 5 a.m. local time in Cameron on the backside of the storm.

In Lake Charles, which took a direct hit, skyscrapers were without glass, while pieces of sheet metal and roofing were seen throughout city streets.

Storm chaser Stephen Jones told "Fox & Friends First" that Hurricane Laura came into Lake Charles with "just as much fury" as it had over the Gulf of Mexico.

"This entire city is severely damaged," he said.

Storm chaser Jeff Piotrowski shared a photo of major damage to one skyscraper in the city.

"Some of the building may be total losses. Many roof off massive flying debris," he tweeted.

There were also reports of some injuries downtown.

"Flying glass from some of the skyscrapers fell on people don’t know the extent of the injuries," Piotrowski said.

First responders dealing with damage in Lake Charles after Hurricane Laura passed over the city now have another problem on their hands.

A large chemical fire from a plant in Lake Charles was sending a massive plume over Interstate 10.

Louisiana State Police told Fox News that emergency services units were on scene, and were closing Interstate 10 in both directions for "precautionary measures."

KABB-TV Meteorologist Brad Sowder tweeted it was an "extremely dangerous situation."

Louisiana State Police said they’re responding to a chlorine leak at the BioLab chemical manufacturing facility in Westlake.

BioLab’s Lake Charles plant was built in 1979 and manufactures trichloroisocyanuric acid, chlorinating granules and other chemicals used in such household cleaners as Comet bleach scrub and pool chlorine powder, according to the Associated Press.

Authorities had ordered coastal residents to get out, but not everyone did in an area that was devastated by 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, told the Associated Press early Thursday morning.

Those who rode out the storm described a long night.

Brett Geymann, who lives in Moss Bluff, just north of Lake Charles, said the eye of the storm passed directly over them. He says his house survived but every other building, structure, and tree on his property is gone.

Geymann told the AP his family was OK but “there's destruction all around" them.

“It looks like 1,000 tornadoes" came through, he said, with some houses “totally gone.”

Other videos from the area showed road signs bending, trees shaking violently and a large recreational vehicle being blown over.

FEMA HEAD WARNS OF 'UNSURVIVABLE SURGE' FROM HURRICANE LAURA, TELLS RESIDENTS TO 'GET OUT'

In Cameron Parish, where Laura came ashore, officials said at least 150 people refused pleas to leave and planned to weather the storm in everything from elevated homes to recreational vehicles. The result could be deadly since forecasters said the parish could be completely covered by ocean water with an "unsurvivable" storm surge of up to 20 feet.

“It’s a very sad situation,” said Ashley Buller, assistant director of emergency preparedness. “We did everything we could to encourage them to leave.”

Officials said search missions and damage assessments would begin when conditions allow it.

“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 electric customers are without power in Texas and Louisiana, according to power-outage tracking website poweroutage.us.

Dick Gremillion, the emergency director in Calcasieu Parish, said hours after landfall that they hadn't been able to get out and look for damage.

"The wind is still over 50 mph. It’s going to have to drop significantly before they can even run any emergency calls. We also need daylight,” Gremillion said in an interview with KPLC-TV.

The Louisiana Universities Marine Consortium (LUMCON) said on Facebook that high tide had passed, but the storm's strong winds "are not allowing water to recede."

Video from the Lafourche Parish Sheriff’s Office showed water rising still rising over LA 1 as winds from Laura still pushed water in from the south.

"This is the highest it’s been, BUT this is outside the South Lafourche Levee System and we’ve had much worse in the past. We’re definitely counting our blessings this morning," Lt. Brennan Matherne tweeted.
