Hurricane Harvey Grows To Category 4 Storm As It Reaches the Texas Coast

Updated at 9:40 p.m. ET

The National Hurricane Center reports that the eye of Hurricane Harvey, now upgraded to a Category 4 storm, has moved onshore to the middle of the Texas coast.

With sustained winds of 130 mph, the storm surge, coupled with tremendous rainfall, threatens to cause significant flooding along much of the state's coastline, forecasters say.

According to the NHC website, the eye of Hurricane Harvey hit between Port Aranas and Port O'Connor, Texas. It warns the "catastrophic flooding" is expected.

Harvey is the first major hurricane to hit the U.S. in a dozen years, as it makes landfall near Corpus Christi, Texas, according to the National Hurricane Center.

There are reports of extensive damage in Corpus Christi. The Washington Post reports "numerous structure destroyed" and "buildings collapsed with people inside." But these reports are only preliminary and fuller damage assessments won't be made until daylight.

Earlier in the day Texas Gov Greg Abbott told residents in the areas between Corpus Christi and Houston to "strongly consider evacuating," according to member station KUT. "Put your life first and your property second."

Abbott said Hurricane Harvey was going to prove "more dangerous than many hurricanes."

Abbott declared a pre-emptive state of emergency in 30 counties encompassing the entire coast in an effort to speed up deployment of resources to the affected areas.

He appeared to avoid criticizing local officials who haven't yet issued mandatory evacuation orders. For example, Houston Mayor Sylvester Turner tweeted, "please think twice before trying to leave Houston en masse." And Francisco Sanchez, the spokesman for Houston's Harris County emergency operations, tweeted: "LOCAL LEADERS KNOW BEST."

According to the NHC, with a Category 4 storm: "Catastrophic damage will occur: Well-built framed homes can sustain severe damage with loss of most of the roof structure and/or some exterior walls. Most trees will be snapped or uprooted and power poles downed. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months."

By Friday evening, Harvey carried maximum sustained winds of 130 mph, according to an NHC Update.

However, Dave Roberts, a hurricane specialist with the NHC in Florida, tells NPR that "as it moves close to the coast later tonight and early Saturday, we should have landfall about that time and as it starts to move further inland, we should see the system begin to slow in forward motion and meander."

When Harvey stalls out, as forecast, it could dump up to 3 feet of rain in some parts of Texas, coupled with up a storm surge of up to 12 feet. The Hurricane Center has issued a storm surge warning for a more-than-400-mile stretch of coastline from Port Mansfield to High Island.

KUT reports that coastal residents are bracing for rain totals forecast to be "10 to 20 inches east of I-35 and totals as high as 25 inches in areas south of I-10 through Tuesday."

Three airlines — American, United, and Southwest — have canceled all flights in and out of Corpus Christi International Airport through the weekend. Several others are rebooking flights for travelers in Austin, Houston and San Antonio.

Carnival Corp. said that three of its cruise ships will not return to the Port of Galveston, Texas, as scheduled. Carnival Freedom and Carnival Valor are headed for New Orleans. A third, the Carnival Breeze, will stay in Cozumel, Mexico, according to a company spokeswoman.

Evacuation orders have been issued for several counties north of Corpus Christi, nearest the area where the hurricane is expected to make landfall. The cities of Portland, Rockport, Port Aransas, Aransas Pass, Ingleside and Robstown have also been ordered to evacuate, as well as all residents of Brazoria County who live on the Gulf side of the Intracoastal Canal, according to The Weather Channel. Galveston County's Daily News reports that the West End of Galveston Island, Jamaica Beach, the Bolivar Peninsula and the city of Dickinson are under a voluntary evacuation.

In an interview with ABC News' Good Morning America, Federal Emergency Management Agency Administrator Brock Long expressed fear "that people may not be taking this storm seriously."

"That window to evacuate is coming to a close," Long said.

White House press secretary Sarah Huckabee Sanders said Friday that President Trump may travel to Texas early next week.

Harvey rapidly moved up the Saffir-Simpson scale beginning Thursday, strengthening from a tropical depression to a Category 1 hurricane. By early Friday, its winds had reached 110 mph, placing it at the top end of Category 2 status, and by the afternoon, it was a Category 3 before increasing in strength even more.

"We're forecasting continuing intensification right up until landfall," National Hurricane Center spokesman Dennis Feltgen was quoted by The Associated Press as saying.

In Houston, Jeff Lindner of the Harris County Flood Control District said Harvey could prove to be a "historic rainfall event."

"We are hurricane-tested here in this state. This is going to be different," Lindner was quoted by Houston Public Media as saying. "This is going to be a hurricane that comes in strong to the mid-Texas coast, and then we're still dealing with it next Monday and Tuesday."

The NHC warns that the deepest water will occur on the coast closest to and northeast of the area of landfall.

The last Category 3 or higher storm to hit the U.S. was Wilma, which smashed into Florida's coast in 2005, causing an estimated $30 billion in damage. It was the same year as Katrina and Rita, a record-breaking hurricane season that included three of the seven most intense Atlantic hurricanes on record.

Hurricane Bret in 1999 is the only major storm to have hit the Texas coast in the past 47 years. One of the most deadly storms was Ike, which killed nearly 200 people after it made landfall as a Category 2 storm near Galveston in 2008. Ike also ranks as the third-costliest Atlantic hurricane on record, after Katrina and Sandy.
