Authorities are warning people along much of the Atlantic seaboard to beware of rip tides from distant hurricanes after a surfer died and a swimmer was reported missing.

Surfers pulled 47-year-old Tazwell Brown from the water off Satellite Beach in central Florida on Saturday. No official cause of death has been determined, but investigators say the Ocoee, Fla., man appeared to have drowned.

Authorities in Ocean City, Md., called off a search Sunday for a 23-year-old man from Washington who went swimming late Saturday.

More than 250 people in Ocean City and roughly 70 on Florida's central Atlantic Coast were rescued from rip currents.

Swimmers are being warned to stay close to shore or out of the water altogether until Hurricanes Danielle and Earl run their course.
