A pickup truck drives Friday through a flooded intersection in downtown Charleston, S.C., as Tropical Storm Hanna threatens the South Carolina coast. As much as 7 inches of rain was expected in the Carolinas, as well as central Virginia, Maryland and southeastern Pennsylvania. Some spots could see up to 10 inches.

Myrtle Beach, S.C. ? Tropical Storm Hanna cruised toward the Carolinas on Friday, forecast to hit land overnight and promising to deliver gusty winds and heavy rain during a dash up the Eastern Seaboard that could wash out the weekend for millions of people.

Not far behind was a much bigger worry: a ferocious-looking Hurricane Ike, on a path similar to the one taken by Andrew, the Category 5 monster that devastated South Florida in 1992. Ike could hit Florida by the middle of next week.

Emergency officials urged evacuations in only a few spots in the Carolinas and about 400 people went to shelters in both states. Forecasters said there was only a small chance Hanna could become a hurricane, and most people simply planned to stay off the roads until the storm passed.

“My vacation lasts through Sunday,” said Jesse King of Asheboro, N.C., who hid under a Myrtle Beach pier as winds picked up and bursts of blinding rain fell Friday evening. “They are going to have to tell me I have to leave if they want me to go before Sunday.”

Rain started falling early Friday on the Carolina coast, with streets in some spots flooding by late afternoon and wind gusts hitting 45 mph as the leading edges of the storm approached land, making people gathered on beaches shout to be heard.

Hanna was expected to blow ashore early this morning between Myrtle Beach and Wilmington, N.C., then race up the Atlantic Coast, reaching New England by Sunday morning. Tropical storm watches or warnings ran from Georgia to Massachusetts, and included all of Chesapeake Bay, the Washington, D.C., area and Long Island.

South Carolina Gov. Mark Sanford said people in low-lying areas, mobile homes, camping trailers or places susceptible to wind damage should consider leaving: “Now is the time to look at taking shelter.”

For all the talk of Hanna, there was more about Ike, which could become the fiercest storm to strike South Florida since Andrew, which did more than $26 billion in damage and was blamed for 65 deaths from wind and flooding along with car crashes and other storm-related accidents.

FEMA officials said they were positioning supplies, search and rescue crews, communications equipment and medical teams in Florida and along the Gulf Coast – a task complicated by Ike’s changing path. Tourists in the Keys were ordered to leave beginning this morning.
