Authorities in Texas confirmed Saturday that at least one person was killed as a result of Hurricane Harvey and up to 14 people were injured.

Charles Wax, mayor of the coastal city of Rockport, said one person died in a house fire as the hurricane came ashore Friday night. Aransas County Judge C.H. “Burt” Mills Jr. told the Austin American-Statesman that 12 to 14 other people were injured.

“It’s pretty sickening,” Mills told the paper. “Lots of emotions are involved when you see your community destroyed like this, but we’ll bounce back.”

Harvey came ashore as a Category 4 hurricane about 30 miles northeast of Corpus Christi, packing winds of 130 miles per hour. It weakened overnight to a Category 1 and then to a tropical storm. By early Saturday afternoon, the storm’s maximum sustained winds had fallen to about 70 mph, and the storm was centered about 60 miles southeast of San Antonio. It was moving north at 2 mph, the Miami-based National Hurricane Center said.

By dawn, nearly 300,000 consumers were without power in the coastal region, and nearly 20 inches of rain had fallen in some places.

But officials warned Saturday that the worst may be yet to come, as rainfall forecast continue for days could dump more than 40 inches of water and inundate many communities, including dangerously flood-prone Houston, the nation’s fourth-largest city.

“Our focus is shifting to the extreme and potentially historic levels of flooding that we could see,” said Eric Blake, a specialist at the hurricane center.

Wax said Rockport, a coastal city of about 10,000 that was directly in the storm’s path, took a blow “right on the nose” that left “widespread devastation,” including homes, businesses and schools that were heavily damaged. Some structures were destroyed.

Wax told The Weather Channel that the city’s emergency response system had been hampered by the loss of cellphone service and other forms of communication.

About 10 people were taken to the county jail for treatment after the roof of a senior housing complex collapsed, television station KIII reported.

In the storm’s immediate aftermath, the Coast Guard sent two helicopters to try to rescue the crews of three tugboats reported in distress in a channel near Port Aransas. And about 4,500 inmates were evacuated from three state prisons in Brazoria County south of Houston because the nearby Brazos River was rising.

In Katy, just west of Houston, a tornado uprooted trees and tore apart a tralier dealership.

Harvey also continued to take a toll on U.S. air travel Saturday, with more than 960 flight cancellations as of mid-day, according to FlightAware. Nearly 800 of the cancelled flights were scheduled to either depart from or land at Houston’s two airports.
