Hurricane-force winds extended up to 60 miles (95 kilometers) from the center and tropical-storm-force winds extend outward up to 230 miles (370 km).

Erin is not forecast to hit the U.S. directly, but coastal areas along the Eastern Seaboard will feel its effects with dangerous high waves and rip currents over the next several days. "These rough ocean conditions will likely cause life-threatening surf and rip currents," the National Hurricane Center warned.

Reports from NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds have increased to near 75 mph. Steady to rapid strengthening is expected during the next two to three days, and Erin is forecast to become a major hurricane this weekend.

Hurricane Erin became the first hurricane of the 2025 Atlantic season on Friday, with sustained winds of 75 mph as it moves toward the Leeward Islands.

Forecasters are tracking a new disturbance in the Atlantic Ocean as Hurricane Erin, a Category 5 storm, undergoes an eyewall replacement cycle, according to a Saturday night update from the National Hurricane Center.

Tropical Storm Dexter is forecast to strengthen in the north Atlantic Ocean, according to the National Hurricane Center.

After exploding in strength at a historic rate this weekend, Hurricane Erin is now a sprawling Category 4 storm churning in the Atlantic. The storm’s enormous footprint is becoming the biggest concern as it threatens to drive life-threatening rip currents and towering waves toward the eastern US coastline and Bermuda.

Hurricane Erin formed Friday in the Atlantic Ocean on track to bring heavy rains that could lead to flooding and landslides in Puerto Rico and the Virgin Islands, forecasters said.
