    What happened

    While blizzards are not uncommon in Colorado, the widespread areal extent of this blizzard was, perhaps a one in 50 year event. A powerful low pressure system moved in from the northwest through Utah, and settled into northern New Mexico. Meantime, arctic air invaded eastern Colorado, setting the stage for high winds, below zero wind chill values, heavy snow, and widespread life threatening conditions. The heavy snow began in the southwest mountains early on Friday morning the 24th. Snow spread across the Eastern San Juan and La Garita Mountains into the San Luis Valley, Upper Arkansas Valley, Wet Mountain Valley, and Sangre de Cristo Mountains through Friday morning. Snow began spreading across the eastern plains by midday Friday. By Friday evening the arctic high pressure and low pressure to the south intensified, and blizzard conditions began in the eastern mountains and across the plains. Blizzard conditions persisted, except for a brief break early Saturday morning, through Saturday night into the extreme eastern plains. The scope and length of blizzard conditions proved fatal for several eastern Coloradans. Three people in El Paso county perished from carbon...

  • Heavy Snow12/24/1997

    Pueblo and Eastern Fremont Counties/Pueblo and Vicinity

    1 death

    What happened

    An upper level low pressure system combined with upslope northerly winds at the surface to produce widespread snow across the southeast mountains and adjoining plains starting the morning of the 24th and lasting into Christmas morning. Storm totals ranged from 4 to 9 inches in and around the Wet Mountains. However, 12 inches of snow fell in Cuchara in the Southern Sangre De Cristo Mountains and in Walsenburg in Huerfano county. One to three inches of snow fell on Monument Ridge, north of Colorado Springs, and in parts of the adjacent plains in southeast Colorado. One fatality was attributed to this storm. James Hall, 83, of Wetmore in Custer county, was found Christmas Eve after apparently falling outside of his home and dying of exposure.
