MIAMI (AP) — Day-old Tropical Storm Debby picked up forward speed Monday on its march toward the Leeward Islands, and forecasters said it could become a hurricane within a day.
Hurricane watches were posted for islands in the northeastern Caribbean.
Debby could pass over the U.S. and British Virgin Islands and reach Puerto Rico by Wednesday if it continues its current west northwest track, forecasters said.
"It's a little too early to say how the storm might affect the United States," said National Hurricane Center meteorologist Eric Blake.
At 8 a.m. EDT Monday, Debby was about 400 miles east of the Leeward Islands and was likely to move over Antigua, Guadeloupe and the rest of the islands early Tuesday.
