Extraordinary Storm Moving Into the Rockies and Central United States

In addition to the high risk of tornadoes (article below this), here is a summary of the various weather alerts out in the region:

Color codes:
  • Orange is a blizzard warning. Keep in mind that in order to have a "blizzard," there must be high winds as well as heavy snow. Don't even think about traveling in the blizzard warning and in northern Colorado where very heavy snow is forecasted to fall.
  • Pink are winter storm warnings.
  • Dark turquoise (MN and IA) are winter storm watches.
  • Blues are winter weather advisories (lesser conditions). Note: I-70 and I-76 may be closed in the advisory areas because of lack of hotel rooms when the storm gets in full swing as the say progresses.
  • Brown = high wind warnings.
  • Greens are various flood watches and warnings. 
  • Magenta = fire weather danger area.
  • Gray are dense fog advisories.
  • Amber = short term severe thunderstorm warnings.
Forecasted Snow Amounts:
Keep in mind when viewing the Denver forecast of 19 inches that the official measuring station is Denver International Airport. On the west side of the city, 20 to 30 inches is forecasted to fall with nearly 40 inches in the foothills.
