Is the storm in Colorado a bomb cyclone?
(But it was.)
A storm hit much of Colorado and the Midwest on March 13, 2019, which underwent bombogenesis. A cyclonic storm becomes a "bomb cyclone" when its central barometric pressure drops especially rapidly — at least 24 millibars in 24 hours, according to the National Weather Service. This type of storm behavior usually requires conditions that occur nearer to an ocean, and may be a first for Colorado. The storm was expected to have an intense impact — and it delivered. Road closures and power outages lasted into Friday in the state, and stranded motorists waited hours for rescue.
