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

After completing an eye wall replacement cycle, Hurricane Erin has now restrengthened to a Category 4 hurricane. Erin had max sustained winds of 130 mph, the National Hurricane Center said in an update on Sunday evening.

Hurricane Erin regained Category 4 strength Sunday night as its outer bands pounded the Virgin Islands and Puerto Rico with gusty winds and heavy rains.
