cyclonic snow

[JonathanBelles]

can there be snow in a cyclone/hurricane/typhoon?

[mike815]

i dont think so lol

[Epsilon_Fan]

Since the season usually ends before snow is possible, I'd say no, but didn't the unnamed hurricane associated with the "Perfect Storm" create heavy snow in the Northeast?

[JonathanBelles]

idk thats y i asked you

[mike815]

lol id say no too much dry

It's in theory impossible since for a tropical system to qualify as a hurricane or tropical cyclone or typhoon it has to possess a warm core in which certainly the temperature will be much above 32 degrees Fahrenheit. Therefore, in theory and I will say, in reality, there can't be snow generated by a tropical cyclone!

[Epsilon_Fan]

Seems reasonable to me... I'm open to suggestion since there are alot more knowledgable people on storms than me on this site. Would the Perfect Storm case qualify as a fully warm-core system since the hurricane was at the center of a larger extratropical low?

It happened during Hurricane Ginny in 1963. Just prior to becoming extratropical, it dropped about a foot of snow due to cold air entering the northwest side of its circulation.

You said it. It was becoming extratropical, which means that its warm core was not existent anymore.

I have no information that indicates snow was reported from a FULLY TROPICAL HURRICANE/TROPICAL CYCLONE/TYPHOON landfall.

UNISYS INDICATES THAT WHEN GINNY MADE LANDFALL IN NOVA SCOTIA IN 1963 IT WAS AN EXTRATROPICAL CYCLONE, THEREFORE, SNOW BECOMES MORE COMMON THAN RAIN THAT FAR NORTH!

Yup good 'ol Ginny of 1963. The infamous "Snow Cane". I actually have a picture of a huge tree that crushed a car outside of our county jail up here, and yes there was quite a bit of snow and ice pellets on the ground in that photo too LOL

[Hybridstorm_November2001]

Here are two Monthly Weather Review articles (in PDF) that mention Ginny:
