Follow Ryan Maue for the play by play:
Usually, in winter, when a Nor’easter forms, there is a weak sfc disturbance along a frontal boundary that slowly grows via ocean moisture and heat flux. It happily moves along if and until it can phase with upper level jet stream. Then, all that available potential energy can be converted into eddy kinetic energy. That potential energy reservoir is enormous, and only a small fraction (4%) can be unlocked. But, it’s what creates the explosive deepening of a “bomb cyclone”.
With Hurricane Fiona, you are not starting at square one with a weak, shallow disturbance at 1007 mb. Instead, you have a massive, Category 3+ monster already at 935 mb. The jet energy is tapped during this rapid re-intensification process.
Explosive barely describes it.
Some background: my MS and PhD research dealt w/these post-tropical cyclones, their climatology, and energy fluxes.
This would be most exceptional Atlantic Ocean case by far.

Unfortunately, the Dauphin will use this as justification for higher gas taxes and banning vehicles that actually can drive hundreds of miles at minus 35.
It has been a remarkably quiet hurricane season up til now, some would argue that energy had to go somewhere. I guess some of it went to people protesting trudeau in London, some went to trudeau singing and dancing on the queen’s grave, and some went to this hurricane.
I’m glad it wont make its way up to Alberta although we will likely see some effect on our weather patterns.
…and Damn, the mornings are getting frosty early this year…no?
No, frosty mornings are the norm for Calgary in September. I’m surprised that the garden still has blooming flowers.
This does affect western Canada, we pay the majority of equalisation which Quebec and the eternally welfare dependent Atlantic provinces leach from.
This storm affecting N.S. and the others will see Zoolander of the #Libranos bail out the Atlantic provinces once again at our expense. Everything the Zoolander of the #Libranos does affects the west poorly.
The only way out from this is to separate from tier 2 Old Canada.
If a hurricane doesn’t make landfall does anyone care?
It’s about to make landfall in NS / NL. They care.
Twenty five years ago I saw (and felt) the result of a hurricane that passed a couple hundred miles east of NS. A truly awesome demonstration of the power of nature. This one looks like it will make landfall. Stay safe.
Winter? It is the autumn equinox. For someone with a PhD in a meteorology subject, this person seems rather shaky on some basic facts.
