HOUSTON—Rescue crews navigated flooded and debris-strewn streets Saturday to search for those who insisted on staying and riding out a fierce Hurricane Ike, which shattered skyscraper windows, cut power to millions and flooded thousands of homes as it sloshed across the Texas coast.

State and local officials began searching for survivors by late morning, just hours after Ike roared ashore at Galveston with 110 mph winds, heavy rains and towering waves. Overnight, dispatchers received thousands of calls from frightened residents who bucked mandatory orders to leave as the storm closed in.

Rescue crews were frustrated, but vowed to get to the more than 140,000 people who stubbornly stayed behind as soon as they could.

“This is a democracy,” said Mark Miner, a spokesman for Gov. Rick Perry. “Local officials who can order evacuations put out very strong messages. Gov. Perry put out a very strong warning. But you can’t force people to leave their homes. They made a decision to ride out the storm. Our prayers are with them.”

Sedonia Owen, 75, and her son, Lindy McKissick, defied evacuation orders in Galveston because they wanted to protect their neighborhood from possible looters. She was watching floodwaters recede from her front porch Saturday morning, armed with a shotgun.

“My neighbors told me, ’You’ve got my permission. Anybody who goes into my house, you can shot them,”’ said Owen.

President Bush declared a major disaster in his home state of Texas and ordered immediate federal aid. Officials were encouraged that the storm surge topped out at only 13.5 feet—far lower than the catastrophic 20-to-25 foot wall of water forecasters had feared, but major roads were washed out near Galveston, and the damage was still immense.

Residents of Houston emerged to take in the damage, even as glass from the JPMorgan Chase Tower—the state’s tallest building at 75 stories—continued to rain on streets below. Trees were uprooted in the streets, road signs mangled by wind.

“I think we’re like at ground zero,” said Mauricio Diaz, 36, as he walked along Texas Avenue across the street from the Chase building. Metal blinds from the tower dotted the street, along with red seat cushions, pieces of a wood desk and office documents marked “highly confidential.”

Houston Police officer Joseph Ledet was out patrolling the streets early Saturday, but stopped and simply stared as he approached Chase Tower. “It looks like a bomb went off over there,” he said. “Just destruction.”

Shortly before noon, Houston police cars prowled downtown, ordering citizens off the streets over bullhorns: “Please clear the area! Go home!”

The storm, which had killed more than 80 in the Caribbean before making landfall in the United States, claimed at least two lives in Texas, but the toll was likely to rise. A woman died early Saturday when a tree fell on her home near Pinehurst in Montgomery County, crushing her as she slept. A 19-year-old man also slipped off a jetty near Corpus Christi and apparently washed away.

The Federal Emergency Management Agency said search and rescue teams were at the ready in Houston, poised to go to the aid of those stranded by Hurricane Ike. At a sports arena, tractor-trailers and large sport utility vehicles sat idle as the vast storm churned northward across the state.

The storm, nearly as big as Texas itself, blasted a 500-mile stretch of coastline in Louisiana and Texas. It breached levees, flooded roads and led more than 1 million people to evacuate and seek shelter inland.

South of Galveston, authorities said 67-year-old Ray Wilkinson was the only resident who didn’t evacuate from Surfside Beach, population 800. He was drunk and waving when authorities reached him on Saturday morning.

“He kinda drank his way through the night,” Mayor Larry Davison said.

Some homes were destroyed, but the storm was not as bad for Surfside Beach as Davison had feared. “But it’s pretty bad,” he said. “It’ll take six months to clean it up.”

Farther up the coast, much of Bridge City and downtown Orange were under up to 8 feet of water and rescue teams in dump trucks were plowing through in an effort to reach families trapped on roofs and inside attics.
