DISCUSSION AND OUTLOOK
----------------------
At 800 PM AST (0000 UTC), the center of Post-Tropical Cyclone Dorian
was located near latitude 51.5 North, longitude 55.5 West.  The
post-tropical cyclone is moving toward the northeast near 23 mph (37
km/h) and this motion is forecast to continue tonight.  A motion
toward the east-northeast is expected Monday through Tuesday.  On
the forecast track, the center of the post-tropical cyclone will
move off of the northern coast of Newfoundland shortly, then move
farther away from Atlantic Canada tonight and Monday.

Maximum sustained winds have decreased to near 60 mph (95 km/h)
with higher gusts.  The post-tropical cyclone should continue to
weaken, and it is forecast to be absorbed by another low pressure
system on Tuesday.

Tropical-storm-force winds extend outward up to 355 miles (575 km)
from the center. St. John's, Newfoundland, recently reported
sustained winds of 38 mph (61 km/h) and a gust of 47 mph (76 km/h).

The minimum central pressure based on surface observations is
estimated to be 979 mb (28.91 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected in the Tropical Storm
Warning area this evening.  Winds will diminish by early Monday.

STORM SURGE: A dangerous storm surge is likely in the northeastern
Gulf of St. Lawrence and the West Coast of Newfoundland.

RAINFALL:  Dorian is expected to produce rainfall accumulations of 1
to 2 inches 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.
