DISCUSSION AND OUTLOOK
At 1100 AM AST (1500 UTC), the center of Hurricane Dorian was
located near latitude 42.0 North, longitude 66.0 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.
Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Dorian is expected to become a hurricane-force
post-tropical cyclone as it moves across eastern Canada tonight or
Hurricane-force winds extend outward up to 105 miles (165 km) from
the center, and tropical-storm-force winds extend outward up to 310
miles (500 km). Yarmouth, Nova Scotia recently reported sustained
winds of 36 mph (57 km/h) and a wind gust of 56 mph (91 km/h).
The estimated minimum central pressure is 953 mb (28.15 inches).
NOAA buoy 44011 reported a minimum pressure of 955.3 mb (28.21
inches) as the center passed just to the west about an hour ago.
HAZARDS AFFECTING LAND
WIND: Tropical storm conditions should spread into the warning area
in Maine by this afternoon.
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 later today, 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.
