All , New York City and Long Island beaches are closed through Aug. 21 as Hurricane Erin makes its way up the Atlantic coast.

Hurricane Erin continues to churn in the Atlantic waters hundreds of miles off the U.S., prompting officials to close beaches along the East Coast from the mid-Atlantic to the Northeast.

Hurricane Erin is bringing 100 mph winds and dangerous rip currents to coastal towns, prompting beach closures and tropical storm warnings from North Carolina to Virginia.

People trying to enjoy the last hurrahs of summer along the coast are being met on Wednesday with rip-current warnings, closed beaches and treacherous waves as Erin inches closer, once again on the cusp of becoming a major hurricane as it treks north after lashing Bermuda.

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.

The massive hurricane was picking up speed, traveling north at 14 mph, and its center was located about 295 miles south-southeast of Cape Hatteras, North Carolina. A tropical storm warning is in effect for parts of North Carolina and Virginia as the impacts from Erin spread northward.

High surf and dangerous rip currents are likely. People are advised to stay out of the water this week, even when a lifeguard is on duty.
