DISCUSSION AND OUTLOOK
At 500 AM AST (0900 UTC), the center of Post-Tropical Cyclone Dorian
was located near latitude 48.5 North, longitude 61.1 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 80 mph (130 km/h) with higher
gusts. These winds are occurring mainly over water. The post-
tropical cyclone is forecast to drop below hurricane strength after
passing Newfoundland later today.
Hurricane-force winds extend outward up to 90 miles (150 km) from
the center and tropical-storm-force winds extend outward up to 345
miles (555 km). A sustained wind of 62 mph (100 km/h) with a gust
to 79 mph (128 km/h) was recently reported at Heath Point on
Anticosti Island. A wind gust to 69 mph (109 km/h) was recently
observed at North Mountain in Nova Scotia.
The estimated minimum central pressure is 960 mb (28.35 inches).

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

SURF: Large swells are affecting the coast of Atlantic Canada, and
they will continue to affect that area during the next few days.
