The first Atlantic hurricane of 2025, Erin ramped up from a tropical storm to a Category 5 hurricane in a mere 24 hours.

Tropical Storm Erin is slightly intensifying and forecast to become a hurricane Friday with a chance of ultimately affecting the U.S. East Coast next week.

Tropical Storm Erin, now spinning far out in the central Atlantic Ocean, could undergo rapid intensification into a powerful 125-mph hurricane.
