Despite changes in intensity, Erin’s size will drive dangerous surf and massive seas along much of the United States East Coast, as well as Atlantic Canada and Bermuda waters.

Hurricane Erin was taking aim at the U.S. East Coast on Tuesday evening, according to forecasters who are warning Americans of life-threatening rip currents along beaches that could persist for days.

Powerful Hurricane Erin is expected to bring high seas, big rip currents, and rough surf as it moves between the United States and Bermuda.
