Tropical Storm Erin poised to become a hurricane, potentially causing risks along the U.S. East Coast.

Tropical Storm Erin, currently in the eastern Atlantic, is expected to become the season's first hurricane by this weekend. While it's unlikely to make landfall in the U.S., it may cause large swells and dangerous rip currents along the East Coast, including Maine, starting next week. The storm is moving west and could impact the Caribbean and Bermuda before curving north. Beachgoers are advised to exercise caution.
