The March 2019 North American blizzard was a powerful Colorado Low that produced up to two feet of snow in the plains and Midwest. Rapid snowmelt following the storm caused historic flooding, and some areas received hurricane-force wind gusts. Comparable to the 1993 Storm of the Century,[1][2] the storm was labeled a bomb cyclone after barometric pressure readings dropped in excess of 24 mbar (0.71 inHg) over a 24-hour period.[3] After the storm entered Colorado from its origination in Arizona, the pressure dropped more than 30 mbar (0.89 inHg) and rapidly intensified over the western High Plains.[4] The severe storm set new all-time record low barometric pressure readings in Colorado, Kansas and New Mexico. The storm itself killed only one person in Colorado, but flooding caused by the storm killed at least 3, one in Iowa and at least two in Nebraska[5][6] and left ~140,000 without power in Texas.[7]
