The Category 2 hurricane saw its winds weaken to as low as 100 mph on Aug. 19 as its north side battled winds, but the National Hurricane Center said early on Aug. 20 that the storm had reformed an inner eye wall, and a Hurricane Hunter mission this morning is expected to help the center determine if winds have increased in response.

Meteorologists are closely tracking the projected path and forecast of Hurricane Erin, which is the first hurricane to develop over the Atlantic this year.
