Conditions along the Florida coast are expected to deteriorate Wednesday as Hurricane Erin moves north-northwest off Florida.

Hurricane Erin is marching north and is set to bring life-threatening rip currents, destructive waves, coastal flooding and possibly beach erosion to much of the East Coast. The conditions will last through Thursday before improving later on Friday and into Saturday.

Hurricane Erin was a Category 4 storm Monday morning and is expected to retain major hurricane status through the middle of the week.

People in the Outer Banks should shelter in place, authorities said. Meanwhile, life-threatening rip currents are likely at beaches along the East Coast, according to forecasters.

Meteorologists are closely tracking the projected path and forecast of Hurricane Erin, which is the first hurricane to develop over the Atlantic this year.

As of the 5 a.m. advisory, Hurricane Erin has max sustained winds at 105 mph, is located 205 miles east-southeast of Cape Hatteras, North Carolina.

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.
