MIAMI — Forecasters have issued a tropical storm warning for Puerto Rico and other parts of the Caribbean as officials expect a disturbance in the Atlantic to soon strengthen into a tropical storm.
The U.S. National Hurricane Center in Miami said Tuesday morning that warnings have been issued for Puerto Rico, the British and U.S. Virgin Islands and numerous other islands including Antigua, Barbuda, Martinique and Montserrat.
If it becomes a tropical storm, it would be named Isaias.
A tropical storm warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours.
On Tuesday morning the system was centered 585 miles (940 km) east-southeast of the Leeward Islands. It was moving west at 23 mph (37 kph).
