ROCKPORT, Tex. — The wind was so intense here that Cathy Dever thought it was a tornado — one that never seemed to end.

Dever fled her double-wide trailer and sought refuge in her neighbor's utility closet, clutching a small plastic bag that contained her son's phone number. If she didn't survive, she thought, at least she would be quickly identified.

For hours she waited, flinching each time gravel and debris slammed against the storm shutters.

"It was so loud, you could hear it picking up rocks off the landscape," Dever, 59, said Saturday, just after Hurricane Harvey made landfall over this spit of land 30 miles northeast of Corpus Christi.

As residents emerged throughout the morning, local officials and emergency responders across the region scrambled to assess the damage.

According to initial assessments, Corpus Christi was relatively spared a devastating impact, although half of the city lost electricity and roofs were blown off some buildings.

But in Rockport, as well as in the adjoining towns of Fulton and Aransas Pass, there were scores of damaged or destroyed properties across communities of mobile homes, middle-class houses and vacation retreats. The Category 4 hurricane tossed the mobile homes across streets and into neighboring structures, chewed through brick buildings and peeled off roofs and aluminum siding.

At the entrance to the resort town of Port Aransas on Mustang Island, law enforcement blocked the road. Power poles dipped tipsily over roads and electric lines lay deep in fast-moving water.

"It is too dangerous," one Port Aransas police officer said. "The roads are collapsing, and there are downed power lines everywhere."

Officers began conducting a search-and-rescue operation for eight people reported missing, according to an Aransas County sheriff's deputy. "There is no cellphone service and no electricity, so we don't know how many people are actually in danger and how many people just can't get through."

Late Saturday afternoon, police started forcing evacuations of residents and tourists who had decided to stay on the island despite mandatory orders to leave, saying it was too dangerous for anyone to remain.

In Rockport, a town of about 10,000 residents, numerous buildings had collapsed, including several iconic structures in the beachy commercial district.

The wind shredded restaurants as well as antique, jewelry and book stores — sometimes randomly. On one street, the Quick & Save store had its roof blown off while the nearby Mac's Pit Barbecue appeared largely intact.

Strip malls and hotels also suffered major damage. At the waterfront hotel Hunt's Castle, the roof was peeled off and most windows were broken. A Washington Post videographer discovered a woman in a ground-floor room, where she was stocked with packs of cigarettes but no food. She refused to identify herself.

Yet the town and broader area appeared to escape the kind of catastrophic damage that Hurricane Katrina, which made landfall as a Category 3 storm, inflicted on the upper Gulf Coast in 2005. Despite predictions of a 6- to 12-foot storm surge, residents and emergency management officials here say that amount of water never materialized.

"I expected a lot worse," Dustin Wright, who lives four blocks from the coast and only suffered minor roof damage, said when he returned home Saturday after an overnight evacuation. "It's a mess, but from what I can tell, the storm surge didn't even make it to me."

What the hurricane lacked in water, though, it made up for in wind. The National Weather Service reported gusts as high as 132 mph at Port Aransas on Friday night.

Long before the eyewall passed over the area, the wind sucked the windows out of nearly a dozen Aransas County Sheriff Department's vehicles.

Jimmy Kendrick, the mayor of Fulton, said he and several emergency management officials used an armored SWAT vehicle to try to escape from the wind. He thinks numerous "mini-tornadoes" passed over the peninsula as Harvey's eye came ashore.

"You couldn't even see the hand in front of your face" in the wind-driven rain, said Kendrick, who lost the Sears appliance store he owns. Two school gymnasiums also were destroyed, he said. "You just look around and see things are totally gone."

Phone, electric and gas service have been crippled throughout the area, and local officials on Saturday were raiding damaged school cafeterias to try to feed emergency workers.

Even in Corpus Christi, which was under a voluntary evacuation and suffered much less damage, unprepared residents struggled Saturday to find gas and food because stores were closed because of no electricity.

Kendrick said it may be weeks before Fulton's evacuees can safely return. Those who refused to evacuate despite a mandatory order — about 1,000 of the town's 2,000 residents — will face days of intense suffering until relief supplies arrive, he predicted. And they're complicating rescue efforts.

At a three-story apartment complex near Fulton, firefighters rescued a man midday after the top story pancaked onto the second floor. Kendrick said about a dozen people were injured there during the storm; many were treated at a makeshift hospital set up at the Aransas County Detention Center.

Susan Stewart, 52, was wandering through deep puddles and navigating around downed power lines with her 31-year-old son, who has mental disabilities, as the two searched for food and cellphone service. Taylor said they didn't have anywhere to evacuate to on Friday so they stayed behind in their trailer.

During the height of the storm, a tree crushed the porch.

"But the trailer is still standing," said Stewart, who attributed her luck to her fellow parishioners at a Pentecostal church. They started praying for her when they heard she didn't evacuate, she said.

"It was all night of slam, bang, boom, but the trailer didn't hardly rock."
