MIAMI (Reuters) - A tropical depression formed in the Atlantic Ocean on Tuesday, prompting tropical storm warnings across several Caribbean islands, and forecasters predicted it will strengthen into a hurricane later this week.
The swirling mass of thunderstorms was located about 580 miles east of Guadeloupe and moving at 20 miles per hour toward the Lesser Antilles, the U.S. National Hurricane Center said.
The depression had top winds of 35 mph. It is forecast to become Tropical Storm Isaac later on Tuesday, the ninth named storm of the Atlantic-Caribbean hurricane season that runs from June 1 to November 30.
