Northern Caribbean islands potential threat from tropical cyclone

Published on August 15, 2009 4:42 AM | Comments

From Caribbean360.com:

BRIDGETOWN, Barbados 15 August 2009 - Tropical Depression 2 has sprung to life again and is a potential threat to the islands in the Northeast Caribbean - parts of the Leeward Islands, Turks and Caicos and The Bahamas.

The National Hurricane Centre has advised the northern Leeward Islands to closely follow the progress of the system which is expected to become a tropical storm on Saturday.

Looks like a busy couple of weeks ahead for the Caribbean after a very slow start to the season.
