Significant amounts of moisture and much below normal temperatures combined together for a late springs now storm across
most of the Colorado high country. The two day storm dropped between 8 and 24 inches of fresh snow which brought the high
country snowpack up to between 140% and 249% above normal on average. Locations above 10,800 feet collected around 24
inches with 8 to 18 inches received at locations such as Leadville, Climax, Thunder Mountain Lodge, Arapahoe Basin ,
Breckenridge, Crested Butte, the Steamboat vicinity, and Hourglass Lake. Due to the lack of warm, spring temperatures in the
mountains, a few snowpack reporting stations were as high as 800% to 1000% of normal for this time of year.

COLORADO, Western, Cont'd
More snow was added to the Colorado high country as an upper low tossed copious amounts of moisture over the mountai n
states. Accumulations of 8 to 18 inches had been received mainly in the Northern and Central Mountains above 7500 feet. The
heavy, wet snow caused numerous traffic problems along Interstate 70 west of Denver to near Vail Pass and was to blame for
a four to five hour traffic jam at some locations along the Interstate. The heavy snow also knocked out power to a long-distance
phone service relay tower in Summit County. The power outage disrupted phone service for five hours between Denver and
western slope.

Northern Foothills
Northeast Plains
Significant moisture and upslope flow caused moderate to heavy rains which began late in the evening ofthe 16th. The rains
which developed in the foothills east of the urban corridor eventually spread eastward out on to the plains throughout the night.
The heavy rains brought many creeks and small streams to bankfull or slightly over. Locations along the northern foothill s
received between three and four inches of rainfall from the storm. Boulder received around 3.60 inches of rainfall for the 24-hour
period causing minor street flooding near small streams. To the northwest of Boulder, a bridge which crossed Fourmile Canyon
Creek had been washed out. A second bridge had been washed out four miles northwest of Lyons in Larimer County. Numerous
cases of rock and mudslides had been reported in the northern foothills and were responsible for closing portions of U.S .
Highways Six, 24, 40, and State Highway 119 for a few hours at a time. Rocks were piled six feet deep on a stretch of Highway
119 along with boulders as large as cars on Highway 6. Locations along the South Platte River between Greeley and Kersey
overflowed the banks at a few locations causing flooding of fields. A parking lot near a creek in Golden caved in leaving a hole
