Tropical Update: Tropical Storm/Depression Gabrielle 9/5/13

11 PM Update | Gabrielle Has Dissipated

Tropical Depression Gabrielle is finally done and is now a remnant low.  While the system is no longer a tropical cyclone the low pressure system remains a heavy rain threat to Puerto Rico and the US Virgin Islands. The NHC will continue to monitor the remnants of Gabrielle for signs of regeneration.

5 PM Update | Gabrielle Barely a Tropical Cyclone

Tropical Depression Gabrielle is holding in there, but just barely.  Gabrielle is barely a tropical cyclone at this point as she sits about 30 miles south-southwest of Punta Cana, Dominican Republic.  She is moving northwest at 9 mph with winds around 30 mph.

According to NHC, Gabrielle is being generously maintained as a tropical cyclone with very little circulation and organized convection.  This is just enough to maintain the classification as a tropical depression. Gabrielle is forecast to weaken and degenerate overnight into Friday morning as she beings interacting with land over the eastern portion of the Dominican Republic.  The main concern with regard to Gabrielle will be heavy rains in the Eastern Caribbean region.

The mid-level activity as we discussed earlier today remains, but there is no sign of the low-level redeveloping in that area.  It is unclear at this time, but there is potential for the impending remnants of Gabrielle to merge with the other disturbance presently north of Puerto Rico in 2 to 4 days.

2 PM Intermediate Update | Tropical Depression Gabrielle Continues to Weakens

Tropical Depression Gabrielle continues to weaken this afternoon and all tropical storm watches and warnings have been discontinued.  The center of what is left of the circulation is located about 55 miles south of Punta Cana, Dominican Republic moving northwest at 9 mph with maximum sustained winds of 30 mph.  Gabrielle remains poorly organized and the National Hurricane Center expects her to degenerate to a remnant low sometime tonight or early Friday as the system begins to interact with land.

While the wind is decreasing the potential for heavy rains has not diminished.  Additionally, tropical storm force wind gusts are possible over portions of Puerto Rico and the Virgin Islands.

The cyclone is is tilted, the low level center of circulation is basically between Puerto Rico and the Dominican Republic.  The mid-level center is located between Puerto Rico and the Virgin Islands. There is a slight chance that the that the low-level center could re-develop below the mid-level center.  If this does happen it is game on, if not Gabrielle will likely dissipate over the course of the next day and a half.
