South Florida beachgoers are being warned of life-threatening rip currents that are expected along the coastline next week, as part of the impacts from Hurricane Erin.

JACKSONVILLE, Fla. — Hurricane Erin was upgraded to a Category 5 as of Saturday’s 11 a.m. advisory. Hurricane hunters were flying in and around the storm all morning Saturday. They found a rapid rate of intensification in the storm, which now has winds of 160 mph.

The National Hurricane Center updated Erin from a Cat 3 at 5 AM, then to a Cat 4 by 6 AM. The center of Erin is forecast to move just north of the northern Leeward Islands, the Virgin Islands, and Puerto Rico over the weekend.

5 p.m. Update: Erin is now organizing and strengthening over the Central Atlantic. Erin is expected to become at least a Catgory 3 hurricane but missing Puerto Rico to the north and staying well east of Florida. It is expected to reach Jacksonville’s latitude about early Wednesday, resulting in some rough seas and surf at area beaches next week.

Invest 97L, an area of low pressure associated with tropical wave now has a high probability of developing next week.
