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.

Erin, the first hurricane of the season, exploded to a Category 5 hurricane Saturday, and despite fluctuations in intensity, the storm is remaining formidable this weekend. Here's where it could head in the week ahead.

Tropical Storm Erin on Tuesday continued to push west through the Atlantic as the National Hurricane Center forecasted it to become a major hurricane with Puerto Rico and other Caribbean islands in its potential path.

Tropical Storm Erin is expected to start to gain strength starting on Wednesday and will likely become a hurricane either Thursday or Friday.

Erin is expected to reach major hurricane intensity this weekend as it tracks just north of the Caribbean islands, where it could bring rain, gusty winds and high surf. Erin's longer-term future through next week is still somewhat uncertain,
