Chelsea Andrews provides an update on Hurricane Laura
Laura is now a dangerous Category 4 hurricane that continues to intensify in the Gulf of Mexico and bring impacts to coastal areas as it edges closer.
AUSTIN, Texas - An intensifying Hurricane Laura is growing stronger by the hour Wednesday over the Gulf of Mexico as forecasters warn the powerful system will be a "catastrophic” Category 4 storm as it's already sending its storm surge along parts of the Gulf Coast.
The U.S. National Hurricane Center (NHC) in Miami said Wednesday morning that Laura, now a major hurricane, is forecast to "rapidly strengthen" throughout the day to an "extremely dangerous" Category 4 storm, bringing life-threatening storm surge, extreme winds, and flash flooding over eastern Texas and Louisiana.
As of 5 p.m. EDT, the storm was located less than 200 miles south-southeast of Lake Charles, La., moving northwest at 15 mph with maximum sustained winds of 145 mph. "Little time remains to protect life and property," the NHC said in its latest advisory.
Satellite images show that Laura has become “a formidable hurricane" in recent hours, threatening to smash homes and sink entire communities.
Impacts and hazards from the storm are already widespread – not just where the center of the storm makes landfall.
A life-threatening and "unsurvivable" storm surge of 7 to 20 feet will inundate the coast just east of the trajectory of the center of the storm. A storm surge warning is in effect from Freeport, Texas to the mouth of the Mississippi River.
According to the NHC, the worst of the storm surge will be along the immediate coast near and to the right of the landfall location, where the surge will be accompanied by "large and destructive waves."
"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," forecasters said. "This storm surge could penetrate up to 30 miles inland from the immediate coastline in southwestern Louisiana and far southeastern Texas."
Even with hours before landfall, the Lafourche Parish Sheriff’s Office said that LA 1 was closed south of Leon Theriot Lock in Golden Meadow due to rising storm surge in the area.

A National Weather Service meteorologist in Lake Charles, Louisiana — in the bullseye of Laura’s projected path — delivered an urgent warning on Facebook Live for people living south of Interstate 10 in southwest Louisiana and southeast Texas.
“Your life will be in immediate and grave danger beginning this evening if you do not evacuate,” Donald Jones said.
Laura has undergone a remarkable intensification, growing nearly 70 percent in power in just 24 hours “and there are no signs it will stop soon," the NHC said in a briefing early Wednesday.
President Trump urged those in Texas, Louisiana, and Arkansas to listen to their local officials as the storm heads toward the Gulf Coast and then moves inland.

"Hurricane Laura is a very dangerous and rapidly intensifying hurricane," the president tweeted.
The 11 a.m. advisory from the NHC has Laura becoming a Category 4 storm before making landfall overnight.
Category 4 storms bring "catastrophic damage," with well-built framed homes at risk of losing most of the roof structure and exterior walls.
"Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas," the NHC states on an overview of damage from similar-sized storms. "Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months."
Laura is becoming a large hurricane as it strengthens by the hour, with hurricane-force winds extending 70 miles from the center and tropical-storm-force winds extending outward of up to 175 miles.
Hurricane-force winds for several hours will cause damage to homes, businesses, and trees. Power outages are also expected.
A hurricane warning is in effect from San Luis Pass, Texas to Intracoastal City in Louisiana.
Flooding will also be widespread from the hurricane. Anywhere between 5 to 10 inches of rain is expected, with isolated totals of 12-15 inches which will cause dangerous conditions along the coast and well inland.
Landfalling tropical systems can spawn tornadoes, and that will be expected over parts of the Lower Mississippi Valley from Wednesday night into Thursday morning.
The storm has forced the evacuation of more than half a million people along the Gulf Coast.

Hurricane Laura evacuees in Austin
On-site officials at the Circuit of the Americas say they are out of vouchers are not longer taking in evacuees. FOX 7 Austin's Tierra Neubaum has details.
LIST: Evacuations ordered in these SE Texas counties and cities
"If you decide to stay, you’re staying on your own,” Port Arthur Mayor Thurman Bartie said.
Louisiana Gov. John Bel Edwards said Laura is shaping up to look a lot like Hurricane Rita did 15 years ago when it ravaged southwest Louisiana. “We’re going to have significant flooding in places that don’t normally see it,” he said.
Fearing that people would not evacuate in time, Edwards said those in southwest Louisiana need to be where they intend to ride out Laura by noon Wednesday when the state will start feeling the storm's effects.
Officials urged people to stay with relatives or in hotel rooms to avoid spreading coronavirus. Buses were stocked with protective equipment and disinfectant, and they would carry fewer passengers to keep people apart, Texas officials said.
Laura passed Cuba 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.
The deaths reportedly included a 10-year-old girl whose home was hit by a tree and a mother and young son crushed by a collapsing wall.
Laura's arrival comes just days before the Aug. 29 anniversary of Hurricane Katrina, which breached the levees in New Orleans, flattened much of the Mississippi coast, and killed as many as 1,800 people in 2005. Less than a month later, Hurricane Rita struck southwest Louisiana as a Category 3 storm.
