As Hurricane Erin churns in the Atlantic Ocean east of Florida, its effects are being felt along Florida's coast.

The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in its advisories.

Additional strengthening is expected as the storm is forecast to “remain a large and dangerous major hurricane through the middle of this week,” the National Hurricane Center said.

From Miami to Maine, the East Coast is under moderate or high rip current risk advisories because of Hurricane Erin

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.

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.

Erin won't make landfall in the Northeast, but it will bring some impacts due to the hurricane's enormous size.

Rough surf conditions and dangerous rip currents have forced many beaches to ban swimming and boogie boarding this week.
