Hurricane Erin weakened to a Category 3 hurricane overnight, but still remains a formidable major hurricane. Erin had max winds of 125 mph, the National Hurricane Center said in a 5 a.m. ET update. The next update is expected at 8 a.m. ET.

Hurricane Erin has been downgraded to a Category 3 hurricane. A tropical storm warning is in effect for the Turks and Caicos Islands as winds and heavy rains continue to lash the Virgin Islands and Puerto Rico.

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