Post-Tropical Cyclone Gabrielle Discussion Number 29
NWS National Hurricane Center Miami FL

AL082019
Issued by the NWS Weather Prediction Center College Park MD
1100 AM AST Tue Sep 10 2019

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
in excellent agreement that the cyclone will move northeastward and
slowly weaken through midweek with the system evolving into an open
trough and dissipating beyond 36 hours prior to reaching the British
Isles.
