When Hurricane Erin made its closest approach to the Delaware beaches on the evening of Aug. 21, 12-foot swell and high tide caused beach erosion and some coastal flooding. Now, the sun is out, and there's one week left before Labor Day.

The National Weather Service is strongly urging beachgoers to stay out of the water in coming days in New Jersey and Delaware as Hurricane Erin churns up dangerous rip currents off coast.

Beaches along the New Jersey coast and in Delaware were closed Tuesday as the powerful storm churned in the Atlantic. New York City announced its beaches would close on Wednesday and Thursday.
