GULFPORT, Miss. -- Hurricane Katrina victims still living in temporary housing along Mississippi's coastline should begin evacuating this weekend as Gustav approaches the Gulf Coast, Gov. Haley Barbour said Friday.
Forecasters say the storm could hit anywhere from the Florida Panhandle to Texas as a major hurricane next week, though caution it is difficult to predict a storm's track and strength several days in advance.
"Let me say to the people of Mississippi: This is not a time to panic, but it is a time to get prepared," Barbour said at a news conference.
There are 4,184 government-provided mobile homes and trailers that remain occupied along Mississippi's 70-mile coast, which was badly hit by Katrina three years ago. Officials are concerned because trailers are vulnerable to damage in high winds.
But it could be difficult to persuade some residents to leave. Sunshine Tatum, 51, whose home was flooded with 6 feet of water in Katrina, has lived in a trailer for three years. Her home still doesn't have full electricity, water and gas service, but she hopes it is strong enough to keep her safe.
"We've got a bunch of animals and we can't just up and leave them," she said. "This house is pretty strong, and I think it's stronger now than it ever was before."
Barbour says mandatory evacuation notices are going out to trailer residents on Saturday. Evacuations of trailers and mobile homes in Mississippi's coastal Harrison and Hancock counties will start Sunday morning and will begin Monday in Jackson County.
The order also applies to some of the 2,800 cottages built as alternatives to trailers. Only those cottages in flood zones are subject to mandatory evacuation.
Barbour said it's too early for Mississippi to decide if a wider evacuation order will be needed. Those decisions will be made in the coming days.
"The blessing, if there is one, is that it's a three-day weekend," he said. "The storm is a long way off. People have a lot of time."
Mississippi was the first state to call for any mandatory evacuations in advance of a possible hit by Gustav. The mayor of Grand Isle, La., a community typically among the first to vacate when severe weather threatens, called for a voluntary evacuation beginning Friday afternoon. New Orleans was organizing buses in case an evacuation was necessary, but had not yet called for residents to leave.
U.S. Homeland Security Secretary Michael Chertoff said federal officials defer to state and local authorities on making evacuation calls, but can help them synchronize their plans.
"We try not to pull the trigger too early on evacuation because you don't want to have false alarms," he said.
