In 2010... high winds downed trees and power lines across
parts of the Front Range foothills and urban corridor.

4-8 in 1969... heavy rains caused flooding on Boulder Creek
in Boulder... which resulted in one death on the 7th.
Flooding also occurred on Bear Creek in Sheridan and
on the South Platte river in Denver. Rain over most
of the eastern foothills started late on the 4th and
continued with only brief interruptions in many areas
until the morning of the 8th. Very high rates of
rainfall occurred on the 6th and 7th with the greatest
intensities in a band along the foothills from about 25
miles southwest of Denver northward to Estes Park. Storm
totals by both official and unofficial measurements
exceeded 10 inches over much of this area and were over 12
inches in some localities. Heavy snow fell in the higher
mountains and in the foothills later in the period. The
saturation of the soil resulted in numerous rock and land
slides... and the heavy run-off caused severe damage along
many streams and flooding on the South Platte river. Many
foothill communities were isolated as highways were blocked
and communications disrupted. Roads were severely damaged
over a wide area... and a large number of bridges washed out.
Many roads were closed due to the danger from Falling
Rocks. A building in Georgetown collapsed from the weight
of heavy wet snow. In Boulder... a man drowned when caught
by the flooding waters of Boulder Creek... and a patrolman was
injured. Rainfall totaled 7.60 inches in Boulder with
9.34 inches recorded at the public service company electric
plant in Boulder Canyon. In Morrison... rainfall totaled
11.27 inches in 4 days. Heavy rainfall totaled 4.68 inches
