Post-Tropical Cyclone Dorian Discussion Number  64
NWS National Hurricane Center Miami FL       AL052019
1100 PM AST Sun Sep 08 2019

The center of Post-Tropical Cyclone Dorian is now located northeast
of Newfoundland over the Labrador Sea where sea-surface temperatures
are less than 10 deg C. No significant convection exists within 120
nmi of the center and, thus, Dorian has become fully extratropical.
Therefore, this is the last advisory on this system.

The post-tropical cyclone is now moving east-northeastward or 060/21
kt. This general motion should continue through Tuesday or until the
cyclone is absorbed by a larger extratropical low.

The NOAA Ocean Prediction Center (OPC) once again provided guidance
on the intensity and wind radii forecasts, and initial 12-ft seas
radii.  The post-tropical cyclone is forecast to gradually weaken
through Tuesday or until it is absorbed by a larger low.

Key Messages:

1. Dorian will continue to cause some impacts across portions
Atlantic Canada into early Monday morning. Storm surge impacts will
gradually subside over portions of the northeastern Gulf of St.
Lawrence and western Newfoundland.  Tropical-storm-force wind gusts
will continue over portions of southeastern Newfoundland into early
Monday but should end by late Monday morning. Refer to information
from the Canadian Hurricane Centre for more information on these
hazards.
