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.

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

With maximum wind speeds back down to 125 mph, Erin remains a Category 3 storm, but is expected to strengthen again in the next few days. NHC said the storm is getting bigger, with hurricane-force winds extending 25 miles from the center and tropical storm-force winds extending up to 205 miles.
