Late last night, NOAA reclassified "#4" as Tropical Storm "Dean".  Dean will most likely become our first hurricane of the 2007 hurricane season. 

Dean will approach the eastern Caribbean by Friday and will possibly be a hurricane.  It's currently traveling West towards South America.

NOAA's storm track (available here) shows Dean moving Northwest as it approaches South America and heading for the eastern Caribbean possibly making initial landfall over the Martinique, Dominica, Guadeloupe area.

Then, according to NOAA,  will track northwest towards western Puerto Rico and the eastern part of Hispaniola (The Dominican Republic) and onward towards the Bahamas.  See the below map - click the map to enlarge.

Northern Caribbean islands of Virgin Islands, Anguilla, St. Martin, St. Barts, Barbuda, Antigua should all pay close attention to the tracking maps.  Currently now, hurricane Dean looks to be glancing by this area on route to Puerto Rico. 

Southern Caribbean islands of Aruba, Curacao, Bonaire, Tortuga, and Margarita should also pay attention to the computer models.

But the islands that look to be right in the middle of Dean's path are: St. Kitts, Nevis, Guadeloupe, Dominica, Martinique, St. Lucia, St. Vincent, The Grenadines, and Barbados and then Puerto Rico, Dominican Republic/Haiti and possibly the Bahamas.  

TheStormTrack.com has other computer models that show the storm with a possible path north towards the east coast of the US, missing the Caribbean entirely.  Unfortunately, most models do have Dean heading right into the middle of the Caribbean.
