Hurricane Erin became the first hurricane of the 2025 Atlantic season Friday (Aug. 15) morning, strengthening as it moves toward the northeast Caribbean and prompting tropical storm watches for parts of the northern Leeward Islands.

Hurricane Erin has quickly intensified into a Category 3 major hurricane as it moves through the Atlantic. Satellite images show Erin has developed a small eye and a well-organized inner core — signs of a strong and powerful storm.
