A false color satellite image provided by the National Oceanic and Atmospheric Administration shows Hurricane Bill at 12:15 a.m. EDT Tuesday Aug. 18, 2009 in the Atlantic Ocean. Forecasters say the first hurricane of this year's Atlantic season has increased to a Category 2 storm with winds whipping at 100 mph.
A hurricane hunter plane found that winds had increased to near 125 mph Tuesday night, making Bill a major hurricane, the first of the Atlantic season.
The National Hurricane Center says people in the Leeward Islands should monitor Bill's progress.
As of 5 p.m. Tuesday, Bill was centered about 635 miles east of the Leeward Islands, moving west-northwest near 16 mph.
The most significant threat the storm seemed to pose was to Bermuda, which it could pass in three or four days. But it also could move directly between Bermuda and the eastern coast of the U.S. without making landfall.
