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.

The hurricane was about 330 miles east-southeast of Grand Turk Island with maximum sustained winds of 125 miles per hour, down from 160 earlier.

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