Hurricane Erin is expected to steer clear of the U.S. East Coast, but its massive impacts could include rip currents on American beaches.

Erin is the first hurricane to develop over the Atlantic this year, and meteorologists are closely tracking its path and forecast.

A tropical storm warning means tropical storm conditions are expected somewhere within the warning area, and in this case, within 24 hours, the NHC said. Heavy rain is still expected across the Virgin Islands and Puerto Rico, with rainfall of 3 to 6 inches, with 8 inches in some isolated areas.
