Major Late February Snowstorm Brings Travel to a Halt  

February 28-29, 2004 - An intense winter storm system moved slowly northeast out of the Great Basin into the Northern Rocky Mountains on Friday Night , and through the Cowboy State on Saturday.  Significant areas of snowfall broke out across southern Wyoming around 5 PM Friday, and spread north reaching the Wind River Basin by around 9:30 PM Friday.  On Saturday, a strong moist southerly flow continued to shift to the northeast and caused winds to turn northeasterly, increasing snowfall intensity in upslope favored areas, especially east of the Continental Divide (eastern Wind River Mountains, eastern Big Horn Mountains, and Casper Mountain).  Numerous area roads were closed on Saturday Morning including Wyoming 135 from Riverton to Sweetwater Station and Wyoming 287 from Sweetwater Station to Highway 789.  The following are snowfall totals as of 1PM Sunday, from this late February snowstorm.  The National Weather Service Forecast Office in Riverton would like to thank all of our spotters who helped make this report possible.
