Harvey intensified into a Category 2 hurricane Friday and steered for the Texas coast with the potential for up to 3 feet of rain, 125 mph winds and 12-foot storm surges in what could be the fiercest hurricane to hit the United States in almost a dozen years.
Forecasters labeled Harvey a "life-threatening storm" that posed a "grave risk." Millions of people braced for a prolonged battering that could swamp dozens of counties more than 100 miles inland.
Landfall was predicted for late Friday or early Saturday between Port O’Connor and Matagorda Bay, a 30-mile stretch of coastline about 70 miles northeast of Corpus Christi.
Harvey grew quickly Thursday from a tropical depression into a Category 1 hurricane Thursday. Fueled by warm Gulf of Mexico waters, the Category 2 hurricane has the potential to become a Category 3. The last storm of that category to hit the U.S. was Hurricane Wilma in October 2005 in Florida.
Superstorm Sandy, which pummeled New York and New Jersey in 2012, never had the high winds and had lost tropical status by the time it struck. But it was devastating without formally being called a major hurricane.
"We’re forecasting continuing intensification right up until landfall," National Hurricane Center spokesman Dennis Feltgen said.
All seven Texas counties on the coast from Corpus Christi to the western end of Galveston Island have ordered mandatory evacuations of tens of thousands of residents from all low-lying areas.
In four of those counties, officials ordered their entire county evacuated and warned those who stayed behind that no one could be guaranteed rescue. Voluntary evacuations have been urged for Corpus Christi itself and for the Bolivar Peninsula, a sand spit near Galveston where many homes were washed away by the storm surge of Hurricane Ike in 2008.
Texas officials expressed concern that not as many people are evacuating compared with previous storms.
"We are going to, in the strongest possible terms, encourage the residents in the low-lying areas, as they say, 'Get out of Dodge,'" Corpus Christi Mayor Joe McComb said.
About 700 members of the state National Guard have been activated ahead of Hurricane Harvey making landfall.
As of late Thursday afternoon, Harvey was about 305 miles (490 kilometers) southeast of Corpus Christi, moving to the north-northwest at about 10 mph (17 kph). Sustained winds were clocked at 85 mph.
Harvey’s effect would be broad. The hurricane center said storm surges as much as 3 feet could be expected as far north as Morgan City, Louisiana, some 400 miles away from the anticipated landfall.
Once it comes ashore, the storm is expected to stall, dumping copious amounts of rain for days in areas like flood-prone Houston, the nation’s fourth most-populous city, and San Antonio.
State transportation officials were considering when to turn all evacuation routes from coastal areas into one-way traffic arteries headed inland. John Barton, a former deputy executive director of the Texas Department of Transportation, predicted state officials will do this before the storm hits, but said timing and determining where to use it are the key factors. Storms change paths and if contraflow starts too early, supplies such as extra gasoline needed to support impacted areas can’t get in, he noted.
"We are closing down," said Bethany Martinez, a front desk clerk at a Holiday Inn Express at Port Aransas.
The 74-room hotel a couple of blocks from the Gulf of Mexico was about two-thirds full before all guests were cleared out.
This would be the first hurricane for Martinez, who is pregnant and has two boys, 5 and 6. They were with grandparents in Austin.
Asked about her demeanor, she replied: "Afraid."
Driscoll Children’s Hospital in Corpus Christi was airlifting at least 10 critically ill, mostly premature infants from its neonatal intensive care unit to Cook Children’s Hospital in Fort Worth. They were expected to arrive by early Friday. Cook transport director Debbie Boudreaux said Driscoll was moving the infants inland for fear that power outages might disable their ventilators.
Harvey would be the first significant hurricane to hit Texas since Ike in September 2008 brought winds of 110 mph to the Galveston and Houston areas and inflicted $22 billion in damage. It would be the first big storm along the middle Texas coast since Hurricane Claudette in 2003 caused $180 million in damage.
It's taking aim at the same vicinity as Hurricane Carla, the largest Texas hurricane on record. Carla came ashore in 1961 with wind gusts estimated at 175 mph and inflicted more than $300 million in damage. The storm killed 34 people and forced about 250,000 people to evacuate.
Dozens were in lines early Thursday at a Corpus Christi Sam’s Club, at home improvement stores and supermarkets. The city also was passing out sandbags.
Alex Garcia bought bottled water, bread and other basics in the Houston suburb of Sugar Land after dropping his daughter off at college. He said grocery items were likely more available in Houston than back home in Corpus Christi, where Garcia, a beer distributor salesman, said stores were "crazy."
"We'll be selling lots of beer," he laughed.
Some stores were running out of supplies as Texans appeared to be heeding the warning of state officials. People waited for hours in long lines to get gas and buy what they could ahead of the storm.
