Tropical Storm force wind gusts have now reached Cape Breton Island and eastern Nova Scotia.  The highest wind gust I have seen so far is at Gabarus with a gust to 49 mph and a pressure of 29.12 inHg (Davis Network) Barometric pressure values close to this are common in that region at this time.

Henry Island just to my west is gusting to 50kts

I'm about half that currently but it's deteriorating here at a faster rate now.

With the dropping pressure, Assuming the center goes over land (0Z output on tropical tidbits have corrected west some) in NS Fiona will quite possibly set the record for lowest pressure recorded in Canada. I believe someone mentioned was 940 mb  from a winter storm.

Have you seen numbers on the expected storm surge there? I haven't found anything, even front their TV broadcasts.  And this is all the NHC says:

 

STORM SURGE: A dangerous storm surge is expected to 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

It has been very tough. This is the official warning for eastern Cape Breton

9:54 PM ADT Friday 23 September 2022
Storm surge warning in effect for:

  • Sydney Metro and Cape Breton County

Higher than normal water levels with very large waves are expected.

Locations: South to southeast facing shorelines of eastern Mainland Nova Scotia
and Cape Breton, as well as southwestern Newfoundland.

Maximum water levels: near high astronomical tide.

Maximum wave heights: 8 to 12 metres, breaking upon approach to shore.

Time span: Early Saturday morning until early afternoon.

High tide: mid to late morning.

Remarks: Very large long period waves will approach the Cabot Strait and gradually diminish west along the Atlantic Coast. Areas west of Guysborough County are expected to remain below warning levels.

Coastal erosion is likely in vulnerable areas. Surge and waves can cause impacts well inland.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to [email protected] or tweet reports using #NSStorm.

All I was seeing were talks about the waves as well.   Ok then.  

I found this on the CHC site for Cape Breton:

Strong category-1 hurricane force winds of 100 gusting to 140 km/h at exposed locations except 140 gusting to 160 km/h at the coast with surge of 1.8 to 2.4 m and dangerous waves from 11 to 15 m from Hurricane Fiona are expected.

I don't think I have ever head of a storm declared post tropical with cat 3 winds.

But I mean-it is post tropical. It doesn’t have a symmetric warm core CDO anymore for sure, and you can see for the last few hours the cold air stratocumulus wrapping into the storm. There’s also the classic baroclinic leaf growing out NW of the storm. Takes nothing away from its destruction and I think Environment Canada will treat “post tropical hurricanes” differently after this storm. Thank goodness it’s not headed directly into Halifax or just west.
