Do sting jets only occur with tropical cyclones transitioning to extra tropical or do they also occur with regular extra tropical storms too?

Regular extratropical cyclones too. Many of the damaging European Windstorms feature sting jets, and it is believed that most of the damage from the 1962 Columbus Day Storm was also from a sting jet. Sting jets also don't occur with every extratropical cyclone, just a few that develop the dynamics for it.

And for that matter, what is a sting jet?

Yeah I would like to know the answer to this question too, if this isn’t too hard to answer. I have a bad feeling I won’t understand the jargon in all the papers that will come up in my search results.

EDIT: there is a Wikipedia page on it. Apparently it has something to do with a cold front fracturing?...I didn’t even realize that was a thing that happened.

EDIT 2: oh wait the cold front fracturing is the whole warm seclusion thing...sorry for my complete ignorance of literally everything.

One of the weather stations in Halifax is now gusting to 76 mph. Hurricane force gusts have arrived there.

I believe it involves the dynamics of very strong extratropical or semi-extratropical cyclones where the air comes together near (usually south of) the center with a warm seclusion also taking place there. It normally requires a pressure around 950 or lower. Sandy also had one at a time when it was offshore.

I know a sting jet became embedded in Arthur back in 2014. That is why places as far inland as Houlton in Maine had 75 mph peak wind gusts.

Back to category two. Nova Scotia is in bring trouble now. I'm thankful I'm not there. Please pray for them, everyone :eek: -

Now Extratropical in the 18Z best track update. The sting jet was a pretty good indication of that.

That and you can see on IR satellite images Dorian has lost nearly all of the deep convection around his core.

Dorian may pass directly over this buoy, should be interesting.

I used to think I knew everything about the weather...until I came here! But it's a good place to learn. :wink:

It's extremely rare to see a hurricane transition into an extratropical cyclone with 85+ knot winds. I wonder what the last one was.

I know Sandy reached 85 kt while in the process but weakened before becoming fully ET. That said, they aren't usually sampled well since they are in distant oceans most of the time.

Osborne Head, just southeast of Halifax, now sustained 64 mph with gusts to 88 mph.

Ginny 1963 (https://en.wikipedia.org/wiki/Hurricane_Ginny) or the Great New England Hurricane 1938 (https://www.weather.gov/okx/1938HurricaneHome) spring to mind as possible candidates.

Or maybe the Nova Scotia Hurricane of 1927 (https://en.wikipedia.org/wiki/1927_Nova ... _hurricane).

I’m gonna say probably Matthew. Transitioned to Extratropical off the Carolina coastal and expanded it’s wind field. We had 15 inches of rain from that storm in Va. Beach with winds gusting to 90 mph.

Is that the remnants of the eye wall just south of Lunenburg?

That is indeed correct. Probably will make landfall near Halifax.

So is Dorian completely extratropical by now? There's still a bit of convection lingering around the core and new convection keeps popping up briefly. Did he reach cat 2 again while tropical?

Looks like it's going to go East of Halifax unless it starts getting tugged now.
