Ophelia looks to be in post-tropical transition and will hit Ireland tomorrow as a post-tropical storm with max winds near 110-120 km/hr.

I'm not so sure, the National Hurricane Service still shows Ophelia hitting Ireland in the vicinity of County Cork on Monday morning as a full on hurricane.

^look at the colour of the circle with the H. Black = tropical, white = post-tropical.

Marty had to explain this to me IRL too, Moncton. Just because it had hurricane force winds doesn't mean it's a hurricane. There are certain tropical characteristics that are required that simply can't be met at higher latitudes. It won't make much difference to the actual experience of it on land, though.

But the "H" in the middle of the circle stands for "hurricane". After landfall, the letter in the circle changes to an "S", standing for tropical storm.

It will still be a tropical storm as it passes over the Shetlands.

I think the letter just means windspeed. We get hurricane force winds frequently here but they're rarely hurricanes.

Well, I certainly know (from Hurricane Juan which hit the Maritimes) that the effective wind strength of a hurricane can be upgraded (along the east side of the storm) because of rapid forward motion accelerating the counterclockwise wind flow. Juan was really a CAT 1 hurricane when it hit Halifax, but since the storm was moving so quickly, it was effectively a CAT 2 hurricane.

In any event, you're right that even if it is "post tropical", it will still effectively have hurricane force winds........

And again you're right in the sense that many winter nor'easters have hurricane force winds but are not hurricanes because they are cold core storms rather than warm core storms.........

It refers to wind-speed of the storm, not whether it's fully tropical or not. A post-tropical storm can have hurricane-force winds; the only difference is how the storm gets its fuel/energy, and how the storm is organized (tropical cyclones have its strongest winds and rain symmetrically to slightly north of the eye, whereas in post-tropical storms heavy rains shift to the left of the centre of the low, and highest wind speeds shift to the right). It doesn't make the storm any less dangerous, but it'd be technically incorrect to say that a "hurricane" will make landfall in Ireland tomorrow (unless Ophelia is able to hold on to some of its tropical characteristics for another 24 hours or so).

Here's the latest NHC technical discission:

000
WTNT42 KNHC 151445
TCDAT2

Hurricane Ophelia Discussion Number 26
NWS National Hurricane Center Miami FL AL172017
1100 AM AST Sun Oct 15 2017

After displaying a distinct eye overnight, recent satellite imagery
indicate that the cloud pattern of Ophelia has begun to deteriorate
and the eye is no longer apparent. The deep convection is also
weakening fast and consequently, Dvorak numbers have begun to
decrease while analysts are trying to lower them as much as the
technique allows. The best estimate of the initial intensity is 80
kt. Given the cold waters of about 20 deg C, and the strong shear,
Ophelia is forecast to gradually weaken and become a post-tropical
cyclone later today.


Satellite fixes indicate that Ophelia is moving toward the
north-northeast or 025 degrees at 33 kt, well embedded within the
fast flow ahead of a large trough. This pattern is expected to
persist, so no significant change in track is anticipated before
dissipation. Guidance continues to be in remarkably good agreement
and most of the models bring a weakened post-tropical Ophelia to the
southern coast of Ireland Monday morning (AST or Miami time).
Thereafter, the cyclone will continue over northern Great Britain
until dissipation.

Strong winds and rains associated with Post-Tropical Ophelia will
arrive well in advance of the cyclone center. Residents in those
locations should consult products from their local meteorological
service for more information on local impacts.

KEY MESSAGES:

1. Ophelia is expected to be a powerful extratropical cyclone with
hurricane force winds while it moves near Ireland and the United
Kingdom.
Direct impacts from wind and heavy rain in portions of
these areas are likely, along with dangerous marine conditions. For
more details on the magnitude, timing, and location of impacts from
post-tropical Ophelia, residents in Ireland should refer to products
issued by Met Eireann, and residents in the United Kingdom should
refer to products issued by the Met Office.

Summer and autumn are always pretty clear. It's the winter when things get bad.

Incredible day...

23C with a humidex of 29. Only negative aspect of today was the overcast skies. Thunder could be heard this evening.

Low of 15C this morning as well.

The warmspot was Saint-Anicet, QC at 25.9C. Had the day been sunny, I have no doubt it would have hit 30C (or at least seriously approach the mark).

St. Catharines, ON with a humidex of 33.

Via FB, with Ophelia on the way, the whole nation of Ireland turns to a single person

Via FB. Up in Labrador this morning:



Here it's going to be mild, windy, and rainy. But looks like we'll be added to that freeze list this week, I suspect.

An incredible 18C in Moncton today when I woke up. Temperatures are supposed to slowly fall through the daytime though.

Went to a Wildcat's hockey game yesterday (currently #1 in the QMJHL) and it was funny to see the crowd entering the building all in tee shirts and shorts. This is how hockey should be experienced.......

Meanwhile Sudbury fell under the bus last night and is now added to the freeze list.

1) - Whitehorse - September 3rd
2) - Iqaluit - September 7th
3) - Prince George - September 14th

Wow. Talk about temperature-focused. It was warm but I can't say much good about the weather yesterday. Grey skies, low ceiling, on and off raindrops, and that weird warmth that doesn't feel truly warm like summer heat. I felt weighed down all day.

But sure it wasn't cold.

A nice n mild 17C today. Mostly sunny changed to mostly cloudy but that should keep our evening from getting too chilly.

Friend was at Harbourside Park today. It's strange how it can look like a proper park from some angles. It looks out through the Narrows.



But, earlier photo, it's so tiny. It's Harbourside Park between Water Street and the harbour, and the National War Memorial between Water Street and Duckworth Street. On the left, that's the entire thing:

Southside Hills Hike by R C, on Flickr

Also, Telephoto lenses are weird. Our old Parliament is that building left-of-centre at top. There's probably 5-6 city blocks between it and the houses behind, it goes pretty far downhill, but you can't tell at all?

When it's that warm in mid-October, I don't really mind the clouds.

Absolute 360 today... 8C and cloudy now THAT's crappy.

Skies are clearing up this evening so we are getting the worst combination of overcast day but clear night.

Frost advisory in effect for:

Châteauguay - La Prairie area

Cover up plants, especially those in frost-prone areas.

Frost advisories are issued when temperatures are expected to reach the freezing mark during the growing season, leading to potential damage and destruction to plants and crops.

Environment Canada predictions are that Ottawa will join the freeze list tonight.
