The already sprawling storm will grow larger as it hurls the ocean toward the East Coast and Bermuda, and it could have company this week.

Hurricane Erin is forcing evacuations on North Carolina’s Outer Banks as it threatens to whip up wild waves and tropical force winds.

Forecasters are confident it will curl north and away from the eastern U.S., but tropical storm and surge watches were issued for much of North Carolina’s Outer Banks.

Two more tropical systems trail Hurricane Erin, which is following a projected course that brushes past the East Coast without making landfall.

Erin is the first hurricane to develop over the Atlantic this year, and meteorologists are closely tracking its path and forecast.

Erin has rapidly intensified into a major hurricane. The storm officially became the first hurricane of the 2025 Atlantic hurricane season on Frida. As of 6 a.m. on Saturday, Erin has become a Category 4 hurricane.

Forecasters are tracking three systems in the Atlantic basin, including one with a medium chance of becoming a tropical depression later this week.
