Tropical Weather Update for Wednesday, October 7 2009

Tropical Storm Henri

The Tropical Atlantic remains slightly more active compared to the previous few weeks.  Tropical Storm Grace is now history as the remnants race into western Europe.  However, a new tropical storm, Henri, has formed to the east of the Leeward Islands.

Tropical Storm Henri continues to get slightly better organized overnight, however it is clear the strongest convection remain to the northeast of the center of circulation at the surface.  Strong southwesterly shear will remain over Henri over the next 48 hours, which should force Henri to weaken and dissipate.

The rest of the tropical Atlantic is quiet as a deep trough from the western Atlantic into the Caribbean continues to produce unfavorable conditions.  A ridge will build over the Gulf of Mexico over the next 48 hours, however a lack of any signs of disturbances will limit any potential for development.  The eastern Atlantic remain quiet as there is no sign of any wave showing signs of development.
