While a curve back out to sea is widely expected and forecast in models, any impacts Erin could have on Florida and the U.S. remains uncertain.

Tropical Storm Erin is gaining strength in the Atlantic and is expected to become the first hurricane of the 2025 season by Friday, forecasters said. Here is the latest hurricane forecast, timeline, spaghetti models and potential Florida impact.

Swells generated by Erin will begin affecting portions of the northern Leeward Islands, the Virgin Islands and Puerto Rico by this weekend. These swells are likely to cause life-threatening surf and rip currents. What impact Erin will have on Florida and the east coast of the United States is known at this time.
