For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center has issued the last advisory

on Post-Tropical Cyclone Gabrielle, located over the far north

Atlantic Ocean.

Shower and thunderstorm activity associated with a surface trough

near the southeastern Bahamas and adjacent Atlantic waters has

increased since yesterday. Limited development of this disturbance

is expected during the next couple of days while it moves

conditions could become a little more conducive for development when

the system moves ...

Gabrielle has now completed its transition to an extratropical
cyclone this morning based on the latest GOES-16 satellite imagery.
The center of the storm has now become exposed with convection
displaced to the north of the center, and a well-defined baroclinic
zone has become established in association with the low center.
Thus Gabrielle is now an extratropical low, and this is the latest
advisory on this system. The intensity remains 45 knots based on
scatterometer data and TAFB Dvorak intensity estimates. Models are

Tropical Storm Gabrielle Discussion Number 28
NWS National Hurricane Center Miami FL

AL082019
500 AM AST Tue Sep 10 2019

Gabrielle's extratropical transition is well underway. Deep
convection is now confined to an area near and to the north of
the center, and a baroclinic zone is already impinging upon the
circulation. The initial wind speed has been maintained at
45 kt, which was in agreement with earlier scatterometer data. The
cyclone should become fully extratropical later this morning, and
the global models indicate that gradual weakening will occur after
that time. As a result, the NHC forecast shows steady weakening
after 12 hours, and calls for the system to dissipate in a little
more than 2 days as it appro...
