(September 3, 2008)--Officials in Georgia, Florida and the Carolinas were weighing possible evacuations Tuesday as they kept a close eye on the weather.
Tropical Storm Hanna is shifting toward a tough-to-predict landfall along the southern Atlantic coast by the end of the week.
Florida Gov. Charlie Crist declared a state of emergency as Hannah began a turn to the northwest from the Bahamas.
Emergency officials in Georgia and South Carolina have gone into 24-hour alert mode.
In Savannah, Ga., nervous residents are rushing to buy plywood and generators.
The National Hurricane Center predicts Hannah will most likely come ashore as a hurricane between Friday and Saturday somewhere between the east coast of Florida and the North Carolina coast.
Current forecasts predict the storm will make landfall near the Georgia-South Carolina border.
At least 21 people are dead in Haiti, where families scrambled onto rooftops to stay above floodwaters triggered by torrents of rain.
Hanna's meandering off the country's northern coast, with 60 mile-per-hour winds.
A U.N. official says "the situation is as bad as it can be" in Haiti. It's been pummeled by three storms in two weeks and more than 100 people have died.
He says with wind ripping up trees, houses flooded and streets impassable, "you can't rescue anyone wherever they may be."
Two other tropical storms have formed farther out in the Atlantic. The hurricane center says Ike could reach the Bahamas by Sunday.
Meanwhile, Josephine has formed to the east of Ike.
