DISCUSSION AND OUTLOOK
----------------------
At 200 AM AST (0600 UTC), the center of Post-Tropical Cyclone Dorian
was located near latitude 47.5 North, longitude 61.8 West. The
post-tropical cyclone is moving toward the north-northeast near 26
mph (43 km/h), and this general motion with a turn to the northeast
is expected during the next couple of days. On this track, Dorian
will be moving near or over western Newfoundland later today and
then enter the North Atlantic this evening.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. These winds are occurring mainly over water. The post-
tropical cyclone is forecast to drop below hurricane strength on
Sunday.

Hurricane-force winds extend outward up to 115 miles (185 km) from
the center and tropical-storm-force winds extend outward up to 310
miles (500 km).  An observing site at Wreckhouse along the
southwestern coast of Newfoundland recently measured a sustained
wind of 54 mph (87 km/h) with a gust to 73 mph (117 km/h).  A
sustained wind of 48 mph (77 km/h) with a gust to 62 mph (100 km/h)
was recently reported at North Point on Price Edward Island. A
sustained wind of 60 mph (97 km/h) with a gust to 78 mph (125 km/h)
was also recently observed at Heath Point on Anticosti Island.

The estimated minimum central pressure is 960 mb (28.35 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm and hurricane conditions are still occuring
over portions of Nova Scotia. Hurricane conditions are also expected
elsewhere in the Hurricane Warning area today. Hurricane conditions
are also possible in the Hurricane Watch area through this morning.
Tropical storm conditions are expected in the Tropical Storm Warning
area today.

STORM SURGE: A dangerous storm surge is likely in the Gulf of St.
Lawrence, the Southwest Coast of Newfoundland, and Eastern Nova
Scotia.

RAINFALL:  Dorian is expected to produce the following rainfall
totals through Sunday Night:

Nova Scotia...3 to 5 inches, isolated 7 inches.
New Brunswick and Prince Edward Island...2 to 4 inches
Newfoundland and far eastern Quebec...1 to 2 inches

These rainfall amounts could result in flash flooding.

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