DISCUSSION AND OUTLOOK
At 200 PM AST (1800 UTC), the center of Post-Tropical Cyclone Dorian
was located near latitude 50.5 North, longitude 58.7 West. The
post-tropical cyclone is moving toward the northeast near 25 mph
(41 km/h), and this general motion is expected to continue during
the next couple of days. On this track, Dorian will be moving near
or over northwestern Newfoundland or eastern Labrador this afternoon
and then enter the North Atlantic this evening.
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. These winds are occurring mainly over water near the west
coast of Newfoundland. The post-tropical cyclone is forecast to
drop below hurricane strength after passing Newfoundland later
today, and it is forecast to be absorbed by another large low
pressure system in a couple of days.
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). Stephenville, Newfoundland, recently reported
sustained winds of 54 mph (87 km/h) and a wind gust of 69 mph
The estimated minimum central pressure is 965 mb (28.50 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions are occurring in the Hurricane
Warning area in Newfoundland at this time, and hurricane conditions
are expected during the next few hours. 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
RAINFALL: Dorian is expected to produce rainfall accumulations of
1 to 2 inches across far eastern Quebec into Newfoundland and
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 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.
