DISCUSSION AND OUTLOOK
At 200 PM AST (1800 UTC), the center of Hurricane Dorian was located
near latitude 42.8 North, longitude 64.9 West. Dorian is moving
toward the northeast near 29 mph (46 km/h), and a general motion
toward the northeast is expected to continue through Sunday night.
On the forecast track, the center of Dorian is expected to move
across central or eastern Nova Scotia this afternoon or this
evening, pass near or over Prince Edward Island tonight, and then
move near or over portions of Newfoundland and Labrador on Sunday.
Recent satellite wind data indicate that the maximum sustained winds
are now near 100 mph (155 km/h) with higher gusts. While Dorian is
forecast to weaken and become a post-tropical cyclone during the
next 24 hours, it is expected to maintain hurricane-force winds as
it moves across eastern Canada this afternoon through Sunday.
Hurricane-force winds extend outward up to 115 miles (185 km) to
the south of the center, and tropical-storm-force winds extend
outward up to 310 miles (500 km). NOAA buoy 44011 to the southwest
of the center recently reported sustained winds of 74 mph (119 km/h)
and a wind gust of 94 mph (151 km/h). A station at Baccarro Point,
Nova Scotia, recently reported sustained winds of 58 mph (93 km/h).
The estimated minimum central pressure is 953 mb (28.15 inches).
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions should spread into the warning area
in Maine during the next several hours.
Regardless of whether Dorian is a hurricane or a post-tropical
cyclone, hurricane conditions are expected in the Hurricane Warning
area in Nova Scotia and Newfoundland beginning this afternoon, and
they are possible in the Hurricane Watch area by tonight. Tropical
Storm conditions are currently spreading into southwestern Nova
Scotia, and these conditions are expected elsewhere in the Tropical
Storm Warning area in eastern Canada later today and tonight.
STORM SURGE: 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 tonight:
Far eastern Maine...1 to 3 inches.
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 increasing along the coast in 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.
