WATCHES AND WARNINGS

CHANGES WITH THIS ADVISORY:

The Canadian Hurricane Center has discontinued all tropical cyclone
warnings for Atlantic Canada.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone
Dorian was located near latitude 52.1 North, longitude 53.4 West.
The post-tropical cyclone is moving toward the east-northeast near
24 mph (39 km/h) and this motion is forecast to continue through
Tuesday.  On the forecast track, the center of the post-tropical
cyclone Dorian will continue to move away from Atlantic Canada
through Tuesday.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Some weakening is forecast during the next 48 hours, and the
post-tropical cyclone is forecast to be absorbed by a larger low
pressure system on Tuesday.

Tropical-storm-force winds extend outward up to 415 miles (665 km)
from the center.

The estimated minimum central pressure is 980 mb (28.94 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical-storm-force wind gusts will continue across portions
of southeastern Newfoundland until early Monday and then diminish by
late Monday morning.

STORM SURGE: Storm surge along the northeastern Gulf of St. Lawrence
and the West Coast of Newfoundland will continue to subside through
Monday morning.

RAINFALL:  Dorian is expected to produce rainfall accumulations of
less than 1 inch across far eastern Quebec into Newfoundland and
Labrador.

SURF:  Large swells are affecting the coast of Atlantic Canada, and
they will continue to affect that area during the next couple of
days. Swells along the mid-Atlantic and New England coasts of the
U.S. will continue for another day or so.  These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.


NEXT ADVISORY

Center on this system.  Additional information on this system can be
found in High Seas Forecasts issued by the National Weather Service,

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.
