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 became one of the earliest Category 5 hurricanes on record on Saturday. The storm will lash parts of the northern Caribbean on Sunday and Monday.

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