DISCUSSION AND OUTLOOK

----------------------

At 1100 PM AST (0300 UTC), the center of Hurricane Fiona was located

near latitude 31.9 North, longitude 68.1 West.  Fiona is moving

toward the north-northeast near 21 mph (33 km/h).  A north-northeast

or northeastward motion with an increase in forward speed is

expected through Friday.  Some reduction in forward speed with a

turn toward the north is forecast Friday night through Sunday.  On

the forecast track, the center of Fiona will pass just to the west

of Bermuda overnight.  Fiona's center will then approach Nova

Scotia on Friday, move across Nova Scotia and into the Gulf of

St. Lawrence on Saturday, and then across Labrador over the

Labrador Sea on Sunday.

Data from an Air Force Reserve Hurricane Hunter aircraft indicate

that Maximum sustained winds remain near 130 mph (215 km/h) with

higher gusts.  Fiona is a category 4 hurricane on the Saffir-Simpson

Hurricane Wind Scale.  Some slight weakening is forecast to begin

tonight or on Friday, however Fiona is forecast to be a large and

powerful post-tropical cyclone with hurricane-force winds when it

approaches and moves over Nova Scotia Friday night and Saturday.

Hurricane-force winds extend outward up to 115 miles (185 km) from

the center and tropical-storm-force winds extend outward up to 275

miles (445 km).

The estimated minimum central pressure is 932 mb (27.53 inches).

HAZARDS AFFECTING LAND

----------------------

Key messages for Fiona can be found in the Tropical Cyclone

Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC

and on the web at hurricanes.gov/text/MIATCDAT2.shtml.

WIND:  Tropical storm conditions have begun on Bermuda, with

hurricane conditions expected overnight.  Tropical storm conditions

should diminish during the day on Friday.

Hurricane conditions are expected in portions of the hurricane

warning area in Canada by late Friday night or early Saturday.

Tropical storm conditions are expected in portions of the tropical

storm warning area in Canada by late Friday.  Tropical storm 

conditions are possible in the watch area in Labrador on Sunday.

RAINFALL:  Fiona is forecast to produce the following rainfall:

Bermuda: 2 to 4 inches (50 to 100 mm).

Nova Scotia, Prince Edward Island, and western Newfoundland: 3 to 6

inches (75 to 150 mm), with local maximum up to 10 inches (250 mm).

This rainfall could result in areas of flooding, some of which may

be significant in nature.

Eastern Newfoundland: 1 to 3 inches (25 to 75 mm).

Eastern Quebec: 2 to 5 inches (50 to 125 mm).

Eastern New Brunswick: 1 to 3 inches (25 to 75 mm).

STORM SURGE:  A storm surge will cause elevated water levels along

the coast of Bermuda in areas of onshore winds beginning tonight.

Near the coast, the surge will be accompanied by large and

destructive waves.

A dangerous storm surge could produce coastal flooding within the

warning areas in Atlantic Canada in areas of onshore winds. Near 

the coast, the surge will be accompanied by large and destructive 

waves.

SURF:  Swells generated by Fiona are affecting the Turks and

Caicos Islands, the Bahamas, the southeastern United States

coast, and Bermuda.  These swells will continue to spread

northwestward across the western Atlantic toward the mid-Atlantic

and northeast coasts of the United States and Atlantic Canada

tonight and on Friday.  These swells are likely to cause

life-threatening surf and rip current conditions.  Please consult

products from your local weather office.

Hurricane Fiona Discussion Number  35

NWS National Hurricane Center Miami FL       AL072022

1100 PM AST Thu Sep 22 2022

Fiona's satellite appearance looks a little more asymmetric this

evening, with deep convection and upper-level outflow becoming more 

restricted on the western side.  That said, the hurricane has not 

yet lost any intensity.  An Air Force Reserve Hurricane Hunter 

mission measured a peak 700-mb flight-level wind of 123 kt and SFMR 

winds as high as 110 kt, which support maintaining a 115-kt 

intensity on this advisory.  In addition, dropsonde data indicate 

that the central pressure has fallen further to 932 mb, and the 

SFMR instrument measured hurricane-force winds now extending 100 n 

mi to the southeast of the center.

The hurricane is still accelerating toward the north-northeast with

an initial motion estimate of 030/18 kt.  Fiona is getting closer

to a deep-layer trough currently located over the northeastern

United States, and this feature is expected to cause the hurricane

to speed up further during the next day or so, reaching peak speeds

of 30-35 kt by 24 hours as it approaches Nova Scotia.  Fiona should

merge with the trough soon after 24 hours, slow down a bit, but

continue moving northward across Atlantic Canada to the Labrador

Sea.  The previous official forecast appears on track based on the

latest guidance, and no significant changes were made to the new

forecast.

Fiona is forecast to remain over warm waters, including within the

Gulf Stream current, during the next 24 hours, although deep-layer

shear is forecast to increase substantially in 12-24 hours.  Given

the hurricane's current appearance, some gradual weakening is

anticipated during the next day or so.  Extratropical transition 

should begin on Friday, and that process is expected to be quick,

with Fiona becoming a warm-seclusion-type extratropical low Friday

night before the center reaches Nova Scotia.  Although continued

weakening is forecast thereafter, Fiona is expected to maintain

hurricane-force winds through 48 hours while it moves across the

Gulf of St. Lawrence.  Winds could drop below gale force by day 5

when the post-tropical low is over the Labrador Sea.  After 24

hours, the NHC intensity forecast is a blend of the GFS and ECMWF

global model solutions.

Key Messages:

1. Hurricane conditions are expected on Bermuda overnight.

Conditions should diminish below tropical storm force during the

day on Friday.

2. Fiona is expected to affect portions of Atlantic Canada as a

powerful hurricane-force cyclone late Friday and Saturday, and

significant impacts from high winds, storm surge, and heavy rainfall

are likely. Hurricane and Tropical Storm Warnings have now been 

issued for much of Atlantic Canada.

3. Large swells generated by Fiona are expected to cause

life-threatening surf and rip current conditions along much of the

east coast of the United States, the Bahamas, Bermuda, and Atlantic

Canada during the next few days.

Area Forecast Discussion

National Weather Service Caribou ME

906 PM EDT Thu Sep 22 2022

.SYNOPSIS...

High pressure will build to our west Friday into Saturday as

Hurricane Fiona tracks through the eastern Maritimes. High

pressure will slide to our south on Sunday while the remnants of

Fiona track into Labrador. Low pressure will approach from the

west on Monday then lift north of the area Tuesday.....

...Previous discussion:

Rain persists across the forecast area as the cold front

continues to drop southward towards the coast. Rain may be heavy

at times along the coast in the presence of the FROPA, and

precipitation will taper off as the surface boundary pushes

offshore. Weather will turn drier overnight behind the cold

front, though winds will turn NW and advect cooler air into the

region. Low temperatures tonight will fall into the 40s across

most of the forecast area.

The pressure gradient aloft will begin to tighten greatly on

Friday as high pressure works its way into New England and the

low pressure which is currently Hurricane Fiona makes its way

into the Canadian Maritimes. As this gradient increases, high

winds will be mixed to the surface, especially beginning Friday

afternoon, and gusts will increase to around 30 mph. These NW

winds will continue to advect cold air into the region, and a

brisk day is on tap with high temperatures only reaching into

the lower 50s across the majority of the forecast area.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...

Main story during the short-term period will be Hurricane Fiona.

The latest forecast has the storm transitioning to a powerful

extratropical cyclone before making landfall near Cape Breton,

Nova Scotia on Saturday morning. This track will keep the

precipitation shield east of the forecast area, but an isolated

shower cannot be ruled out in far eastern areas.

However, Fiona’s circulation will expand as it transitions to an

extratropical cyclone, which will bring strong, gusty northwest

winds Friday night and Saturday. Wind gusts of 45 mph, with a

few gusts possibly reaching or even exceeding 50 mph are

forecast across Eastern Aroostook County, Northern and Central

Penobscot County, and over Downeast Maine. These winds are

capable of downing trees and knocking out power, especially as

leaves are still on the trees and the ground is saturated from

recent rainfall. As such, a High Wind Watch has been issued for

these areas Friday night through early Saturday evening. Further

west, winds will not be quite as strong, but wind gusts up to 40

mph are expected. These winds still have the potential to

produce some power outages. Winds will subside Saturday night as

Fiona pulls away to the north.

With the northwest winds, temperatures will be chilly Friday

night and Saturday. Expect lows Friday night in the upper 30s

across the north, with 40s elsewhere. High temperatures on

Saturday will be in the 50s across most of the area, with 60s

near the coast due to downsloping winds. Temperatures will

moderate to near normal on Sunday as milder air aloft advects

into the region.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...

A low pressure system a will track northwest of the area Sunday

night and Monday, bringing with it the threat of rain.

Confidence is relatively high, so went with likely pops over

much of the area on Monday. Kept high chance to likely pops

across the north Monday evening across the north as rain showers

are expected to hang on longer there. An upper-level low will

trail this low pressure system, so the chance of showers will

continue through Tuesday and Wednesday. Models show high

pressure building into the area on Thursday, bringing some dry

weather. Temperatures are forecast to be near normal Monday and

Tuesday, then fall below normal Wednesday and Thursday behind

the upper-level low.

The next information statement will be issued by 3:00 a.m. ADT.

Fiona expected to impact Atlantic Canada and eastern Quebec with heavy rainfall and powerful hurricane force winds beginning early Saturday.

1. Summary of basic information at 9:00 p.m. ADT.

Location: 31.0 North 68.6 West.

About 1622 kilometres south-southwest of Sable Island.

Maximum sustained winds: 213 kilometres per hour.

Present movement: northeast at 38 kilometres per hour.

Minimum central pressure: 935 millibars.

2. Public weather impacts and warnings summary.

This storm is shaping up to be a severe event for Atlantic Canada and eastern Quebec. Numerous weather models are quite consistent in their prediction of what we call a deep hybrid low pressure system, possessing both tropical and intense winter storm properties, with very heavy rainfall and severe winds.

The latest forecast guidance brings Hurricane Fiona north towards Nova Scotia waters Friday night, passing through eastern mainland Nova Scotia or western Cape Breton Saturday, and then reaching the Lower Quebec North Shore and Southeastern Labrador early Sunday. Severe winds and rainfall will have major impacts for eastern Prince Edward Island, eastern Nova Scotia, western Newfoundland, eastern Quebec, and southeastern Labrador. There will also be large waves, especially for the Atlantic coasts of Nova Scotia, Newfoundland, and eastern portions of the Gulf of St. Lawrence. Finally, there is a high likelihood of storm surge for parts of Nova Scotia, the Gulf of St. Lawrence and western Newfoundland.

a. Wind.

Most regions will experience hurricane force winds. These severe winds will begin impacting the region late Friday and will continue on Saturday. Similar cyclones of this nature have produced structural damage to buildings. Construction sites may be particularly vulnerable. Wind impacts will likely be enhanced by foliage on the trees, potentially causing prolonged and widespread utility outages.

Hurricane and tropical storm watches are now in effect for most areas. Many regions will see these watches upgraded to warnings tonight.

b. Rainfall.

Rainfall will be significant, especially north and west of Fiona's track, where heavy rain could lead to flooding. The highest rainfall amounts are likely for eastern Nova Scotia, southwestern Newfoundland, and the Gulf of St. Lawrence region. Forecast guidance is suggesting widespread amounts of 100 to 200 mm, but closer to the path of Fiona, more than 200 mm is likely. Some districts have received large quantities of rain recently, and excessive runoff may exacerbate the flooding potential. Road washouts are also possible.

Rainfall warnings are now in effect from the Atlantic Storm Prediction Centre for most of Nova Scotia, PEI, and southeastern New Brunswick.

c. Surge/Waves.

There will be some rough and pounding surf, especially for parts of Nova Scotia, the Gulf of St. Lawrence and Newfoundland. Large waves will reach the eastern shore of Nova Scotia from the south on Friday night and build to more than 10 metres. These waves will likely reach southern Newfoundland by Saturday morning. Some of the waves over eastern portions of the Gulf of St. Lawrence could be higher than 12 metres. The western Gulf will see waves from the north up to 8 metres in places, which will probably cause significant erosion for north facing beaches of Prince Edward Island. Iles-de-la-Madeleine will also see some coastal erosion from waves.

Coastal flooding will also be a threat for parts of Nova Scotia, Prince Edward Island including the Northumberland Strait, the Gulf of St. Lawrence region including Iles-de-la-Madeleine and eastern New Brunswick, and southwest Newfoundland. The highest risk for coastal flooding will be a combination of storm surge with large waves moving onshore. There may also be some coastal flooding for the St. Lawrence Estuary and the Quebec Lower North Shore. For most areas the highest water levels will be near high tide some time on Saturday morning.

3. Marine weather impacts and warnings summary.

Hurricane force winds will spread into Scotian Slope waters Friday evening, and these winds will persist near the track as Fiona moves northward through the region. Gale to storm force winds will impact most remaining marine waters. Waves in excess of 12 metres should form east of the hurricane track.

Tropical cyclone technical information statement issued by the

Canadian Hurricane Centre of Environment Canada at 8.56 PM ADT

Thursday 22 September 2022.

The next statement will be issued by 3.00 AM ADT

1. Current position, strength, central pressure and motion

At 9.00 PM ADT, hurricane Fiona was located near latitude 30.8 N and

longitude 68.8 W, about 891 nautical miles or 1650 km south-southwest

of Sable Island. Maximum sustained winds are estimated at 115 knots

(213 km/h) and central pressure at 932 MB. Fiona is moving northeast

at 20 knots (38 km/h).

3. Technical discussion

A. Analysis

Fiona, still a category 4 hurricane, is beginning to accelerate

northeastward at 20 kts. Ascat mostly missed Fiona, but what it did

catch shows that the wind field on Fiona is already quite expansive.

Also, wind shear is currently light and with a diminishing tendency,

and this will persist for the next 12 to 24 hours. Intensity will be

maintained at 115 kts.

B. Prognostic

Current indications suggest only a slight decrease in intensity over

the next 12 hours as the hurricane travels in a moist environment,

over very warm waters, and under light to moderate wind shear. Later

on Friday, the hurricane will begin to accelerate as it interacts

with a mid-latitude trough approaching from the west. This will bring

the hurricane near Sable Island on Friday night as it undergoes

extra-tropical transition. Then post-tropical storm Fiona is expected

to make landfall over Eastern Mainland Nova Scotia or Cape Breton

Saturday morning while decelerating slightly and maintaining

sustained hurricane force winds. New guidance suggests that Fiona is

progressing northeastward faster than originally anticipated and the

new track reflects this. The cumulative qpf field from the rdps/gdps

suite is indicating a pre-cursor rainfall event well ahead of the

centre beginning as early as Friday morning or afternoon. Rainfall

totals suggested by the main models are showing more than 200 mm

north and northwest of the track.

7:18 PM ADT Thursday 22 September 2022

Rainfall warning in effect for:

Fredericton and Southern York County

Rain, at times heavy, is expected.

Total rainfall: 40 to 60 mm.

Locations: southwestern New Brunswick.

Time span: until early Friday morning.

Remarks: Rain at times heavy, with localized downpours possible. The rain is expected to ease after midnight.

Heavy downpours can cause flash floods and water pooling on roads.

Rainfall warnings are issued when significant rainfall is expected.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to NBstorm@ec.gc.ca or tweet reports using #NBStorm.

12:03 PM ADT Thursday 22 September 2022

Tropical storm watch in effect for:

Moncton and Southeast New Brunswick

Tropical storm force winds of possible 60 gusting to 90 km/h over exposed areas from Hurricane Fiona may occur over the above regions.

This watch will be upgraded to a warning tonight for most regions. At that point, we will begin forecasting some specific wind speeds.

A tropical storm watch means that tropical storm conditions (sustained winds near 65 km/h or more) are possible over parts of the region within 36 hours.

By nature, a tropical storm also implies the threat of local flooding from heavy rainfall - consult your local area forecast for possible rainfall warnings.

Please continue to monitor alerts issued by the Canadian Hurricane Centre and forecasts issued by Environment Canada. Reports of storm conditions and impacts can be emailed directly to NSstorm@ec.gc.ca or by tweeting reports by province using #NSStorm, #NBStorm, #PEStorm, #NLwx, #QCStorm or #ONStorm.

10:56 PM ADT Thursday 22 September 2022

Rainfall warning in effect for:

Sydney Metro and Cape Breton County

Heavy rain is expected.

Total rainfall: 50 to 100 mm, local amounts possible reaching 150 mm.

Locations: central and northern Nova Scotia, and northern and eastern Cape Breton Island.

Time span: tonight through Saturday afternoon.

Remarks: A trough of low pressure will bring rain to the region tonight and Friday. This trough will then merge with approaching Hurricane Fiona later on Friday and will bring intense and torrential rainfall to the region. Rainfall rates in excess of 25 mm per hour are possible beginning later Friday night and will continue into Saturday. Rain will finally ease off then end during the day Saturday.

Past storms with these rainfall rates and total accumulations have caused hazardous driving conditions, elevated river levels, road closures, and localized flooding, especially in poor drainage areas.

Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

Rainfall warnings are issued when significant rainfall is expected.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to NSstorm@ec.gc.ca or tweet reports using #NSStorm.

10:58 PM ADT Thursday 22 September 2022

Rainfall warning in effect for:

Queens County P.E.I.

Heavy rain is expected.

Total rainfall: 50 to 100 mm, local amounts possible reaching 150 mm.

Locations: Prince Edward Island, with the highest amounts most likely over Kings County.

Time span: tonight through Saturday afternoon.

Remarks: A trough of low pressure will bring rain to the region tonight and into Friday. This trough will then merge with approaching Hurricane Fiona later on Friday and will bring intense and torrential rainfall to the region. Rainfall rates in excess of 25 mm per hour are possible beginning overnight Friday night and will continue into Saturday. Rain will finally ease off then end Saturday afternoon.

Past storms with these rainfall rates and total accumulations have caused hazardous driving conditions, elevated river levels, and localized flooding, especially in poor drainage areas.

Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

Rainfall warnings are issued when significant rainfall is expected.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to PEstorm@ec.gc.ca or tweet reports using #PEStorm.

 

Watches

12:02 PM ADT Thursday 22 September 2022

Hurricane watch in effect for:

Queens County P.E.I.

Full hurricane conditions from Hurricane Fiona are possible.

This watch is in effect for Saturday and will likely be upgraded to a hurricane warning tonight. At that point, we will begin forecasting some specific wind speeds. It is possible that full category-one type wind conditions could occur with this storm including the possibility of category-two scale gusts.

Residents under this watch - which is for the core of Hurricane / severe post-tropical storm Fiona - are strongly encouraged to take this storm seriously.

A hurricane watch means that hurricane conditions are possible over parts of the region within 36 hours. Hurricane conditions include (A) sustained winds near 120 km/h or more, and/or (B) significantly elevated water levels and dangerous surf along the coast.

By nature, a hurricane also implies the threat of local flooding from heavy rainfall - consult your local area forecast for possible rainfall warnings.
