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.

Tropical Storm Erin may near Puerto Rico and the Dominican Republic before likely turning north as a hurricane, sparing the U.S.

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.
