Hurricane Erin is forecast to continue growing in size, with hurricane-force winds extending up to 50 miles from its center.

Erin is a strong Category 3 hurricane, the National Hurricane Center said in its 8 p.m. ET update Sunday, with sustained winds of 125 mph and tropical storm-force winds reaching out 205 miles. The storm is just over 300 miles northwest of Puerto Rico as of Sunday evening.

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.

Hurricane Erin continues to rapidly intensify in the Atlantic Ocean with its outer bands starting to impact the northern Leeward Islands.

Erin developed in the eastern Atlantic, moving westward from the Cabo Verde Islands at about 20 mph (32 km/h). Infrared sensors on NOAA's GOES-19 satellite reveal colder cloud tops and deep convection near the center — signs of a strengthening system feeding on warm ocean waters.

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.

The National Hurricane Center is predicting Invest 97L could become a tropical depression or tropical storm as early as later this morning, Aug. 11.
