In 1997 one of the worst and deadliest blizzards of the decade developed over eastern Colorado as deep east to northeast flow associated with a vigorous upper level low pressure system over the four corners…combined with a strong arctic air mass over the central great plains. Snowfall totals across metro Denver ranged from 14 to 31 inches. The heaviest snowfall occurred in the foothills west and southwest of Denver where 2 to 4 feet of snow were measured.
Sustained winds to 40 mph with gusts as high as 60 mph produced zero visibilities and extremely cold wind chill temperatures from 25 below to 40 below zero. Winds whipped the snow into drifts 4 to 10 feet deep.
Several major and interstate highways were closed as travel became impossible. Red Cross shelters were set up for hundreds of travelers who became stranded when they had to abandon their vehicles. Four people died in northeastern Colorado as a result of the blizzard. None of the deaths were in metro Denver.
