The next statement will be issued by 3.00 AM ADT

1. Current position, strength, central pressure and motion

At 9.00 PM ADT, post-tropical storm Fiona was located near latitude

48.8 N and longitude 59.8 W, about 52 nautical miles or 96 km

at 60 knots (111 km/h) and central pressure at 955 MB. Fiona is

moving northeast at 30 knots (56 km/h).

3. Technical discussion

A. Analysis

Post-tropical storm Fiona is now a large and powerful mid-latitude

system. Local gusts to near - hurrcane force persist for parts of

Southwestern Newfoundland and Îles-de-la-Madeleine. Wind radii have

increased significantly over the last 12 hours. A wide band of storm

force winds are east of the track and a very large area of gales

surround the entire system.

B. Prognostic

Fiona is moving off to the northeast and will slowly accelerate

towards Southeast Labrador. While this is happenning it will begin to

interact with an upper trough and curve northwards. The system will

start to develop frontal features tonight, albeit not too strong.

Model guidance is generally very good, and the track is effectively

unchanged. The storm will then dissipate over the Labrador Sea on

Sunday night.

DISCUSSION AND OUTLOOK

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

At 500 PM AST (2100 UTC), the center of Post-Tropical Cyclone Fiona

was located near latitude 48.4 North, longitude 60.5 West. The

post-tropical cyclone is moving toward the northeast near 8 mph (13

km/h). A faster north-northeast or north motion is expected

through Monday.  On the forecast track, the center of Fiona will

move across Labrador and over the Labrador Sea late tonight and 

Sunday.

Maximum sustained winds are near 70 mph (110 km/h) with higher

gusts.  Gradual weakening is expected during the next couple of

days.

Tropical-storm-force winds extend outward up to 550 miles (890 km)

from the center.

The estimated minimum central pressure based on surface 

observations is 952 mb (28.12 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:  Gale-force and storm-force winds are expected to continue

across portions of Atlantic Canada through early Sunday.

RAINFALL:  Fiona is forecast to produce 1 to 2 inches (25 to 50 mm) 

of rainfall across portions of Atlantic Canada, with storm total 

maxima as high as 10 inches (250 mm) across Nova Scotia, New 

Brunswick, Prince Edward Island, and western Newfoundland. Flooding 

is expected, some of which could be significant.

STORM SURGE: A dangerous storm surge is expected to produce coastal

flooding in portions of 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 Atlantic Canada, the

northeastern United States coast, and Bermuda. The swells are

likely to cause life-threatening surf and rip current conditions.

Please consult products from your local weather office.

Post-Tropical Cyclone Fiona Discussion Number  42

NWS National Hurricane Center Miami FL       AL072022

500 PM AST Sat Sep 24 2022

Fiona remains a large and potent extratropical low pressure system.

Even though the maximum winds have decreased just below

hurricane-force, ASCAT data and surface observations show that

Fiona has a very large wind field.  The initial wind speed is

estimated to be 60 kt.

Fiona has slowed down significantly, and the system is now moving

northeastward at 7 kt.  A faster north to north-northeast motion is

expected, taking the center of the system across Labrador tonight

and early Sunday.  The NHC track forecast is similar to the

previous one.

Since the tropical warnings have been discontinued for Atlantic

Canada, this is the last NHC advisory on Fiona.  For information on

this system, see forecasts issued by Environment Canada at

https://weather.gc.ca/.  Additional information can be found in

High Seas Forecasts issued by the National Weather Service, under

AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and online

at ocean.weather.gov/shtml/NFDHSFAT1.php

Key Messages:

1. Fiona is forecast to continue to affect portions of Atlantic

Canada through early Sunday, and significant impacts from high

winds, storm surge, and heavy rainfall are expected.

2. Heavy rains from Fiona are expected to continue to impact

portions of Atlantic Canada into Sunday. This rainfall is expected

to produce flooding, some of which could be significant.

3. Large swells generated by Fiona are expected to cause

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

the northeast United States, Bermuda, and Atlantic Canada during

the next couple of days.
