WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:
The Tropical Storm Warning has been discontinued for the coast of
Maine.
Environment Canada has discontinued the Tropical Storm Warning in
New Brunswick from the U.S./Canada international border to south of
Fundy National Park, from Belledune to north of Shediac, and north
of Lower East Pubnico to west of Avonport along the Fundy Coast of
Nova Scotia.
SUMMARY OF WATCHES AND WARNINGS IN EFFECT:
A Tropical Storm Warning is in effect for...
* New Brunswick from the Fundy National Park to Fort Lawrence and
from Tidnish to Shediac including Grand Manan Island
* Nova Scotia from Fort Lawrence to Avonport and then east from
Lower East Pubnico to Tidnish
* Prince Edward Island
* Magdalen Islands
A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning, in this case today through
Sunday.
For storm information specific to your area, please monitor
products issued by your national meteorological service.
DISCUSSION AND OUTLOOK
----------------------
At 1100 PM AST (0300 UTC), the center of Post-Tropical Cyclone Lee
was located near latitude 45.3 North, longitude 65.5 West. The
post-tropical cyclone is moving toward the north-northeast near 14
mph (22 km/h). A faster northeastward motion is expected during the
next day or so, taking the system across the Canadian Maritimes.
Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Steady weakening is forecast the next couple of days.
Tropical-storm-force winds extend outward up to 290 miles (465 km)
from the center.
The estimated minimum central pressure is 979 mb (28.91 inches).
HAZARDS AFFECTING LAND
----------------------
Key messages for Lee can be found in the Tropical Cyclone Discussion
under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC and on the
web at hurricanes.gov/text/MIATCDAT3.shtml
WIND: Tropical storm conditions are occurring along portions of the
coasts of New Brunswick and Nova Scotia and will spread northward
within the Tropical Storm Warning areas overnight. The strong
winds are leading to downed trees and power outages.
SURF: Swells generated by Lee are affecting Puerto Rico,
Hispaniola, the Turks and Caicos Islands, the Bahamas, Bermuda, the
east coast of the United States, and Atlantic Canada. These swells
are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
RAINFALL: Lee is expected to produce an additional 1 inch or less,
or 25 millimeters or less, from portions of eastern Maine into parts
of New Brunswick and far western Nova Scotia. This may produce
localized urban and small stream flooding.
STORM SURGE: A dangerous storm surge will produce coastal flooding
within the wind warning areas in Atlantic Canada in areas of
onshore winds. Near the coast, the surge will be accompanied by
large and destructive waves.

Post-Tropical Cyclone Lee Discussion Number 47
NWS National Hurricane Center Miami FL AL132023
1100 PM AST Sat Sep 16 2023
Satellite imagery, surface observations and Canadian radar imagery
indicates that the center of Lee is over the Bay of Fundy, near the
coast of New Brunswick. Rain bands continue to spread across
portions of far eastern Maine and New Brunswick this evening. Drier
air is wrapping into the system and has eroded most of the
convection on the southern and eastern side of the circulation.
Recent observations and a recent partial ASCAT pass support an
intensity of 50 kt for this advisory.
The forward motion of Lee is slower than earlier today, as the
system has stated to make a northeastward turn . This northeastward
motion with an increase in forward speed is expected late tonight
and Sunday, as the system moves across the Canadian Maritimes. The
NHC forecast track is very similar to the previous forecast.
Strong wind shear, dry air, and land interaction should cause
steady weakening over the next day or so as Lee spins down. The
global models are in agreement that Lee should dissipate on Monday,
and no real changes were made to the NHC intensity forecast.
KEY MESSAGES:
1. Tropical storm conditions and coastal flooding are occurring
across portions of Atlantic Canada, and will continue to spread
northward within the Tropical Storm Warning areas. The strong winds
are leading to downed trees and power outages.
2. Any additional rainfall from Lee may produce localized urban and
small stream flooding in portions of eastern Maine and portions of
New Brunswick and Nova Scotia.
3. Dangerous surf and life-threatening rip currents will continue
to affect the U.S. East Coast, Atlantic Canada, Bermuda, the
Bahamas, the Turks and Caicos Islands, Hispaniola, and Puerto
Rico through Sunday.

8:41 PM ADT Saturday 16 September 2023
The next intermediate information statement will be issued at 12:00 am ADT, with a full information statement again at 3:00 am ADT.
Strong post-tropical storm Lee is now located near Saint John. Lee will continue to impact the region tonight with rain or showers, strong winds, and high waves along the Atlantic coast.
1. Summary of basic information as of 9:00 pm ADT.
Location: near 45.1 degrees North 66.0 degrees West.
About 23 km south-southwest of Saint John.
Maximum sustained winds: 110 kilometres per hour.
Present movement: Northeast at 22 kilometres per hour.
Minimum central pressure: 975 millibars.
2. Public weather impacts and warnings summary.
Tropical storm warnings are in effect for much of the Maritimes and parts of Quebec.
The circulation around Post-Tropical Storm Lee is quite expansive
and impacts are occurring not only near the track but several
hundred kilometres away from it.
a. Wind.
Wind warnings are in effect for most of the Maritime provinces.
Widespread winds of 70 km/h with gusts of 90 to 100 km/h are occurring or will soon occur. Given the abundance of rainfall over the past several months, and in recent days, the ground is quite saturated therefore trees may more readily become uprooted. We have seen several reports of this today. Widespread utility outages are occurring across much of the Maritimes. Some structural damage to roofing materials and siding, as well as exterior fixtures and fencing have been reported.
b. Rainfall.
Rainfall warnings are in effect for much of New Brunswick eastern regions of the Gaspe Peninsula, Anticosti Island and portions of the Quebec Lower North Shore. The rainfall warnings for Nova Scotia have been recently ended.
In the end, rainfalls in excess of 100 mm are possible, especially in
areas near and to the left of the track.
c. Surge/Waves.
High waves and elevated water levels are widespread due to the
large size of the storm - the most impacted areas have been along the Atlantic coast of mainland Nova Scotia and to a much lesser extent, the Fundy coast of New Brunswick. Wave conditions are also rough in the western Gulf of St Lawrence / western Northumberland Strait but should remain below warning criteria. This includes all of the east coast of New
Brunswick.
For Atlantic coastal Nova Scotia breaking waves of 4 to 6 metres (15 to 20 feet) are occurring in areas facing the open ocean. Elevated water levels (storm surge) combined with waves have resulted in coastal flooding during the high tide earlier today from Shelburne County to Guysborough County. This could be an issue again this evening during high tide. Water levels up to 1.5 metre (5 feet) above high tide is possible. Storm surge warnings are in effect from Shelburne County eastward to Guysborough County, causing some further beach erosion.
3. Marine weather impacts and warnings summary.
Storm or gale warnings are in effect for most waters. Significant wave heights up to 15 meters or so have been recorded in offshore waters south of Nova Scotia.
