Swimmers are being warned about possible riptide currents as Tropical Storm Bertha passes within a few hundred miles of southern New England.
Forecaster says Bertha will be moving east of New England through Thursday morning bringing swells of 5 to 8 feet. Massachusetts State Police Sergeant Blake Gilmore, of the underwater recovery unit, says swimmers should check conditions, heed the advice of lifeguards and not swim alone.
"Rip currents flow into the beach area and then funnel out in a very strong pattern that can pull people away from the shore."
The riptide warnings affect Cape Cod, Martha’s Vinyard, Nantucket, the south coast of Rhode Island and Block Island.
