Tropical Storm Erin is expected to become the first hurricane of the 2025 Atlantic hurricane season later this week, according to forecasters at the National Hurricane Center. Erin formed in the eastern Atlantic Ocean on Monday and continues to move westward.

Erin could potentially strengthen to sustain wind speeds of over 115 miles per hour in the next four days, making it a Category Three hurricane on the Saffir-Simpson scale and the first major hurricane of the Atlantic season.
