Tropical Storm Chantal Racing Through the Eastern Caribbean 7/9/2013

11 PM Update

The center of Tropical Storm Chantal is passing about 215 miles south of Puerto Rico. Chantal has picked up about 2 mph and is currently moving at 28 mph, but her minimum central pressure has risen to 1009mb and maximum sustained winds have dropped to 60 mph. The latest updated suggests there will be little change in intensity between now and the time she makes landfall in Hispaniola.  The forecast track shifted slightly to the west.

The rapid forward motion of Chantal could suggest that a westerly low to mid level shear is having an affect which could limit intensification between now an the time she makes landfall in Hispaniola.  Once Chantal interacts with the topography of the land mass should disrupt the circulation causing significant weakening or best case dissipation.  If Chantal survives the interaction with the land mass and strong westerly shear, the system could restrengthen as she makes her way into the Bahamian waters.  The NHC notes that there is significant uncertainty in the intensity forecast 3 to 5 days from now.

This is the last update for 7/9/2013.  There will be a new post Wednesday to document the tropical storm.
