Andrea could bring up to a foot of flooding on the sound side of the Outer Banks, Elardo said.
The rain threatened to ruin a beach day Friday for Angela Hursh, 41, of Cincinnati, who had rented a house in Frisco, N.C. Hursh was planning to soak in the hot tub and watch movies with her 9-year-old and 13-year-old daughters.
"I think we're just going to hunker down and eat junk food," Hursh said.
Doug Brindley, who owns a vacation lodging rental service on the northern end of the Outer Banks near Virginia, said he expects all outdoor activities to be washed out Friday, driving tens of thousands of early-summer vacationers toward unexpected shopping sprees.
"We're going to have rain and wind," said Brindley, who owns Brindley Beach Vacations and Sales. "Retailers are going to love it."
He expects new visitors streaming south from their homes across the U.S. Northeast to arrive tired and grumpy.
"They're going to be driving through that mess," Brindley said.
In Cuba, heavy rains associated with the storm system have soaked the western part of the island for the past several days, overflowing rivers and damaging crops. At least 30 towns were cut off by flooding, and more than 2,600 people sought refuge from the rising waters at relatives' homes or state-run shelters, the Communist Party newspaper Granma reported Thursday.
