The term is shorthand for explosive cyclogenesis, aka bombogenesis, a phenomenon characterized by a swiftly deepening low-pressure area capable of producing heavy winds — which, when twinned with a forecast for heavy snow, like the one for the metro area today, March 13, can produce blizzard conditions.
Hence school closures before a single flake hit the pavement and widespread cancellations, with Denver government offices and libraries among the places where doors will remain locked today. The latter announcement came complete with a link to the city's snow plan.
Of course, Colorado residents are accustomed to dealing with wintry weather. But after local, regional and national meteorologists began dropping "bomb cyclone" warnings over the past day or so, plenty of folks went from normal preparations (checking tire pressure, making sure the windshield wipers are in good condition) to full-fledged freak-out.
And predictably, the bomb cyclone struck social media before any snow hit Denver (at this writing, it's only raining).
Some Twitter users are reacting with legitimate fear and concern. But as you'll see by our collection of responses below, others are laughing in the face of danger. Among those weighing in are TV weather personnel armed with wry GIFs and memes and even longtime Westword contributor Bree Davies, whose insurance broker is already hammering the panic button.
Consider what follows to be an essential part of storm preparation. Bombs away!

I know I said yesterday it was C-17 Globemaster, and that is still a pretty good name if you're going for a certain aesthetic, but Bomb Cyclone just has better mouth feel.

Spring may be just a week away, but Old Man Winter isn't going quietly. A "bomb cyclone," an intense and ferocious winter storm, will strike the nation's midsection today. #WinterStorm #WednesdayWisdom pic.twitter.com/XQDUDPH2bD

If we're frantic, life will be frantic.
If we're peaceful, life will be peaceful.
And so our goal in any situation becomes inner peace.” #InnerPeace #Settings #BombCyclone

If/when this weather turns super awful, I'll start live tweeting from the eye of the #BombCyclone (which sounds like a shitty 90's rap rock band)

I'm loving all of these cool names meteorologists are thinking of for weather phenomenon, like "BOMB CYCLONE" or "POLAR VORTEX".

Soon, Kim Jong Un will cease this opportunity to weaponize the weather. Like a sharknado, but instead of sharks it is filled with bombs.

Gassed up the car in case I have to sleep in it due to power loss. Not ideal, but at least I'll have heat and can power my laptop and watch movies. Things are about to go to hell in a handbasket here in Colorado in about 6-7 hours. #BombCyclone #ColoradoBlizzard #cowx #FrontRange

Kids' schools closed tomorrow in anticipation of "cyclone bomb". I've lived in Colorado for 45 years. Never heard of this weather phenomena. But I'm sure everything is FINE. IT'S FINE.
