ABSTRACT

I

A survey was conducted for evidence Df thunderstorm
heavy rainfalls occurring at elevatiDns above 7,500
feet in the central Colorado Front Range foothills.
During the period Df April to September 1979 24 cases
Df thunderstorm rainfalls of 2.00 inches or mDre were
fDund in the Jefferson, Teller, Gilpin and Clear Creek
CDunties. Several cases of 4.00 inch or more rainfall
were fDund, These thunderstorm rainfalls appear tD be
at odds with other recent research which suggests the
lack Df heavy rains at elevations abDve 7,500 feet.
Three model thunderstDrm rainfall profiles are proposed
for cDnsideration by planners until definitive research
can be conducted.
