WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

The Canadian Hurricane Center has discontinued all tropical cyclone
warnings for Atlantic Canada.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

There are no coastal watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone
Dorian was located near latitude 52.1 North, longitude 53.4 West.
The post-tropical cyclone is moving toward the east-northeast near
24 mph (39 km/h) and this motion is forecast to continue through
Tuesday.  On the forecast track, the center of the post-tropical
cyclone Dorian will continue to move away from Atlantic Canada
through Tuesday.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Some weakening is forecast during the next 48 hours, and the
post-tropical cyclone is forecast to be absorbed by a larger low
pressure system on Tuesday.

Tropical-storm-force winds extend outward up to 415 miles (665 km)
from the center.

The estimated minimum central pressure is 980 mb (28.94 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical-storm-force wind gusts will continue across portions
of southeastern Newfoundland until early Monday and then diminish by
late Monday morning.

STORM SURGE: Storm surge along the northeastern Gulf of St. Lawrence
and the West Coast of Newfoundland will continue to subside through
Monday morning.

RAINFALL:  Dorian is expected to produce rainfall accumulations of
less than 1 inch across far eastern Quebec into Newfoundland and
Labrador.

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

Post-Tropical Cyclone Dorian Discussion Number  60
NWS National Hurricane Center Miami FL       AL052019
1100 PM AST Sat Sep 07 2019

The center of Post-Tropical Cyclone Dorian made landfall near
Sambro Creek, Nova Scotia several hours ago. Since then, the
powerful cyclone has continued to move rapidly to the
north-northeast and is now just east of Prince Edward Island.  The
wind field has expanded considerably, and the cyclone is producing
tropical-storm-force winds over an extensive area of the Canadian
Maritimes.  The powerful cyclone is expected to continue with a
large wind field, but gradual weakening is anticipated as forecast
by most of the global models.

The best estimate of the initial motion is toward the north-
northeast at 23 kt. Since the cyclone is embedded within the fast
extratropical westerly flow, this general track with a turn to
the northeast is anticipated until dissipation in about 2 days.
Track guidance is in very good agreement with this motion, and the
NHC forecast follows the guidance envelope.

The Ocean Prediction Center (OPC) provided guidance to prepare
this forecast.

The National Hurricane Center will continue to issue advisories on
Dorian as a post-tropical cyclone until the threat to eastern
Canada has ended.

Key Messages:

1. Dorian will continue to have significant impacts in portions
of eastern Canada overnight and Sunday. Dangerous storm surge
impacts are likely in portions of the Gulf of St. Lawrence,
southwestern Newfoundland and eastern Nova Scotia.  Hurricane-force
winds are still occurring in Nova Scotia and are forecast to occur
in Newfoundland overnight. Refer to information from the Canadian
Hurricane Centre for more information on these hazards.

Post-Tropical Cyclone Dorian Discussion Number  59
NWS National Hurricane Center Miami FL       AL052019
500 PM AST Sat Sep 07 2019

Satellite imagery and surface observations indicate that Dorian has
lost tropical cyclone characteristics and is now a hurricane-force
extratropical low.  The initial intensity is held at 85 kt based
mainly on the earlier scatterometer data.

The initial motion is 040/26.  Strong mid-latitude southwesterly
flow should steer Dorian across Nova Scotia and other portions of
eastern Canada during the next 24-30 h.  After that, the cyclone
should turn east-northeastward over the far north Atlantic, with
this motion continuing for the rest of the system's life.

Global model guidance indicates that the post-tropical cyclone
should gradually weaken as it moves across eastern Canada, and the
new intensity forecast brings the winds below hurricane force by 24
h.  Additional weakening should then occur until the storm is
absorbed by a large extratropical low to its north.

The National Hurricane Center will continue to issue advisories on
Dorian as a post-tropical cyclone until the threat to eastern
Canada has ended.

Key Messages:

1. Although Dorian has lost tropical cyclone characteristics, it
will have significant impacts in portions of eastern Canada tonight
and Sunday. Dangerous storm surge impacts are likely in portions of
the Gulf of St. Lawrence, southwestern Newfoundland and eastern Nova
Scotia.  Hurricane-force winds are also likely in Nova Scotia,
Prince Edward Island and Newfoundland later today and tonight. Refer
to information from the Canadian Hurricane Centre for more
information on these hazards.

Hurricane Dorian Discussion Number  57
NWS National Hurricane Center Miami FL       AL052019
1100 AM AST Sat Sep 07 2019

Satellite imagery this morning indicates that Dorian is starting
extratropical transition, with cold air clouds entraining into the
southwestern side of the cyclone and a developing warm front to the
north and east.  However, the cyclone still has persistent
convection just north and northeast of the center, so it remains a
hurricane on this advisory.  NOAA buoy 44011 reported a minimum
pressure of 955.3 mb as the center passed just to the west, so the
initial central pressure is lowered to 953 mb.  The initial
intensity remains 75 kt based partly on recently-received WindSat
data showing hurricane-force winds southwest of the center.

Dorian continues to move rapidly northeastward with an initial
motion of 040/25 kt.  The current motion should bring the center
of Dorian over central and eastern Nova Scotia in about 12 h and
near or over Prince Edward Island shortly thereafter.  Subsequently,
Dorian is forecast to move near or through northern Newfoundland
and southeastern Labrador before turning east-northeastward over the
far north Atlantic.  There are no significant changes to the
previous forecast, and the new forecast is again close to the
various consensus aids.

Dorian is expected to complete extratropical transition during the
next 24 h as it merges with a strong mid- to upper-level trough and
associated surface frontal zone.  The global models agree on a
gradual decay of the winds after transition is complete.  However,
the cyclone will likely still be producing hurricane-force winds as
it moves through portions of eastern Canada.  The global models also
agree that the post-tropical cyclone should become absorbed by
another extratropical low in 2-3 days.  The NHC intensity forecast
again leans towards the GFS and ECMWF models, which typically handle
large extratropical lows better that than the intensity models that
are made for tropical cyclones.


Key Messages:

1. Regardless of whether it is a hurricane or a post-tropical
cyclone, Dorian is expected to have a significant impact in portions
of eastern Canada beginning during the next several hours. Dangerous
storm surge impacts are likely in portions of the Gulf of St.
Lawrence, southwestern Newfoundland and eastern Nova Scotia.
Hurricane-force winds are also likely in Nova Scotia, Prince Edward
Island and Newfoundland later today and tonight. Refer to
information from the Canadian Hurricane Centre for more information
on these hazards.

Hurricane Dorian Discussion Number  55
NWS National Hurricane Center Miami FL       AL052019
1100 PM EDT Fri Sep 06 2019

During the past couple of hours Dorian's eye has become no longer
apparent in conventional satellite imagery. Microwave data shows an
eye-like feature just to the south of the convection, and also
indicates that the hurricane is becoming asymmetric. The lack of
symmetry is the first indication or hint that Dorian is slowly
beginning to acquire some extratropical characteristics. The rain
shield is now placed to the northwest of the center, and the wind
field is expanding in the southern semicircle.  Dvorak numbers are
either steady or have decreased slightly, and consequently the
initial intensity is kept at 80 kt in this advisory.

The hurricane is rapidly reaching cooler waters and guidance shows
an area of significantly strong shear along the forecast path
of Dorian. Given these conditions, the NHC forecast calls for
gradual weakening, but Dorian is still expected to make landfall in
Nova Scotia with hurricane intensity late Saturday. Dorian is
forecast to complete its transition to extratropical once it crosses
Nova Scotia.

The hurricane is racing northeastward or 045 degrees at 22 kt. Since
Dorian is already embedded within a fast southwesterly flow ahead of
a mid-latitude trough, the current northeast heading should
continue until dissipation occurs in about 3 days, if not sooner.
The track guidance is in remarkably good agreement, and the NHC
forecast is in the middle of the guidance envelope, increasing the
confidence in the track forecast.

Key Messages:

1. Regardless of whether it is a hurricane or a post-tropical
cyclone, Dorian is expected to have a significant impact in portions
of eastern Canada. Dangerous storm surge impacts are likely in
portions of the Gulf of St. Lawrence, southwestern Newfoundland and
eastern Nova Scotia this weekend. Hurricane-force winds are also
likely in Nova Scotia, Prince Edward Island and possibly
Newfoundland Saturday and Sunday. Refer to information from the
Canadian Hurricane Centre for more information on these hazards.
