Dorian was located near latitude 46.3 North, longitude 62.1 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
on Sunday and then enter the North Atlantic late Sunday.

Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. These winds are occcuring 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).

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 overnight and Sunday.
Hurricane conditions are also possible in the Hurricane Watch area
overnight.  Tropical storm conditions are expected in the Tropical
Storm Warning area on Sunday.

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
