Is the storm in Colorado a bomb cyclone?
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.
A second storm with bomb cyclone potential was predicted for April 10-11, 2019. The storm did become a bomb cyclone by definition, but the impact in most of Colorado was nothing like the first.
