Imo it's possible though it'd have to somehow not weaken below HU status first

remnant low idk but extratropical cyclones that happens often

I don’t think it’s happened before, but hypothetically it’s possible if a TC’s convection can wane and collapse quicker than its max sustained winds can drop below hurricane-force.

Like Sierra said, this happens many times with hurricanes transitioning into extratropical cyclones.

Officially it's not possible because remnant lows have to be below hurricane force

@Catsarecool558 Oh yeah I forgot. RL is only below storm-force winds. Any higher than that and it’ll just be called “post-tropical”.

it is worth mentioning that briefly Pulasan of last year was classified as a monsoonal typhoon before being overwritten to TS

@CycloneTracker15 Yep. I just found that out. The only exception is Hurricane Calvin (2011), when it was declared a remnant low whilst having storm-force winds.

So now I’m wondering…. the correct terminology would technically be “post-tropical but not extratropical cyclone?” XD

Edit: *I accidentally put TS instead of remnant low. Hopefully you guys knew what I was talking abour*

It's be like how EPac storms are post-tropical, so pretty much a RL but it's post-tropical

@ChilledAntoine Welllll things get a bit more complicated here…

Technically, you could call any tropical cyclone that that became extratropical or a remnant low “post-tropical”, but that wouldn’t fit the actual definition of the term. Extratropical would be a non-tropical frontal system while post-tropical would be a non-tropical NON-frontal system, while a remnant low is a subset of post-tropical except the criteria includes that the system must have lower than storm-force winds.

Hopefully that all makes sense! 😅

(Also I think you meant “declared a remnant low” not “declared a TS”) :)

@CycloneTracker15 Yep. I did mean remnant low. Whoops!
