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.

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.

Hurricane season spans from June 1 to November 30. Here’s what you should know before Erin or any future storm approaches land.
