        winds caused one fatality and minor injuries to others.
        West winds were sustained to 46 mph in downtown Denver
        where the strong chinook winds warmed the temperature to
        a high of 74 degrees.

        Denver with 10 to 20 inches in the foothills.  At Stapleton
        International Airport...6.1 inches of snow fell and north
        winds gusted to 47 mph reducing the visibility to as low
        as 1/8 mile in heavy snow.  Strong north winds at 20 to 30
        mph with frequent gusts to 40 mph and temperatures hovering
        around 30 degrees plunged wind chill temperatures to
        5 below zero.

        involved in the pileup.  Although there were no fatalities...
        18 people were seriously injured and taken to nearby
        hospitals.  The northbound lanes of I-25 were closed for
        several hours...snarling the traffic between Denver and
        Colorado Springs.

        sustained to 60 mph with gusts to 75 mph on the 15th.

        after midnight.
      In 1996...around a foot of new snow fell in the foothills
        west of Denver with 3 to 6 inches at lower elevations
