Residents in the Florida Keys breathed a sigh of relief Monday as a fierce Hurricane Ike turned west on a path away from the low-lying island chain. But Gulf Coast states watched anxiously to see if the storm was gunning for them instead.

Forecasters at the National Hurricane Center warned that, after passing into the Gulf of Mexico sometime Tuesday night, Ike could make landfall in the U.S. over the weekend near the Texas-Louisiana border, possibly not far from Houston.

Texas Gov. Rick Perry pre-declared disasters in 88 counties to aid storm preparation and put 7,500 National Guard members on standby.

Hurricane Ike has weakened to a Category 1 storm, and a hurricane warning for the Florida Keys has been discontinued, forecasters said in a 5 p.m. ET advisory.

In Louisiana, where thousands remain without power after Hurricane Gustav hit last week, Gov. Bobby Jindal urged residents to start stockpiling food, water, batteries and other supplies. The state also was readying shelters and making plans for trains, buses and planes in case a coastal evacuation is called later in the week.

With the storm on a new track, Keys officials let an evacuation order expire Monday. Ike is still supposed to deliver heavy rain and wind, and authorities suggested residents who had left stay away until Wednesday. They said those who stayed behind should stay inside, and tourists should wait for the weekend to return. Roughly 20,000 tourists left over the weekend when it looked like Ike could make a direct hit.

Many storm-hardened locals just rode out the hype the way they usually do - drinking. Key West residents are a hardy bunch, generations of whom have lived through storms. They typically take a wait-and-see stance.

In hard-backed chairs lined up on the sidewalk, a 72-year-old sat with old friends, drinking beer wrapped in paper bags and watching the winds blow.

Businesses were not as cavalier. It was the second time in a month vacationers left en masse. Tourists also cleared out of the Keys last month ahead of Tropical Storm Fay, and their departure means a hit to the bottom line. Officials estimate tourists spend about $175 a day in the Keys. With some 20,000 having fled for Ike, that's about $3.5 million for each day they're gone.

Ike roared ashore in eastern Cuba Sunday night, blowing homes to rubble and sending waves crashing over apartment buildings. By Monday afternoon, Ike had maximum sustained winds of about 100 mph (160 kph). The storm was expected to hit Havana early Tuesday.

The storm first slammed into the Turks and Caicos and the southernmost Bahamas islands as a mean Category 4 hurricane that peeled off roofs and knocked down buildings. At least 61 people were killed as it pelted Haiti.

By early afternoon Monday, a Category 2 Ike had moved just offshore of Cuba, where the storm was maintaining its strength over warm water, said Felix Garcia, a meteorologist at the National Hurricane Center.

With the current forecast models, Jindal said he doesn't anticipate the sort of mass evacuations forced by Gustav, which emptied out most of south Louisiana, including the New Orleans area. Instead, coastal communities vulnerable to tidal surges and larger areas of southwest Louisiana would likely be asked to seek refuge away from their homes.

"Roughly speaking, they think there's about a one in three chance that the storm will make landfall in Louisiana," Jindal said of his conversations with forecasters. "We're just getting ready for the worst-case scenario."
