LENGTHY LIST OF HEAVY
RAIN, FLOOD AND MUDSLIDE REPORTS STATEWIDE
Mother nature did not take
long to deliver downpours on Tuesday, starting the in the northwest part of the
state before noon and quickly spreading across the Divide into the Front Range
by early afternoon and farther south and eastward into the evening and
overnight hours. Most of the heavy rain squalls lasted anywhere from 40 to 60
minutes, delivering up to 2.5 inches of rain in one hour. One particular
downpour moved by our office in downtown Denver during the mid afternoon and
dropped 0.63 inches in about 14 minutes before subsiding. Many locations
received multiple such thunderstorms, leading to widespread rain totals above 2
inches across the state (mainly east of the Divide) with some locations in the
southeast exceeding 4 inches. Below is a small sampling of the many impressive 24-hour
rain totals (for a more complete list, check out the Colorado
CoCoRAHS reports). Of course, check out our map below for a statewide
(County): Amount (inches)
Forest (El Paso): 2.52
(Denver): 2.10* [Also, record daily rainfall at DIA of 1.80 inches]
Springs (Routt): 1.65
Ford (Otero): 0.87
Vista (Rio Grande): 0.65
we all know, in Colorado, these kinds of rainfall totals usually imply a hefty
flood threat. Indeed, as of 8:45AM this morning roughly three dozen flash
flood, flood and debris flow reports had been noted. Quite a few of the flood
reports came from Larimer and Weld counties where numerous roads were impassable
due to standing or moving water. Another aggregate of reports came from Prowers
County, where the 3-5 inches of rainfall resulted in quite a few road closures.
At least 3 reports of debris flows, rock and mud slides were reported over the higher
terrain of Eagle, Moffat and Delta counties. The Eagle County report stated
that I-70 was closed at mile marker 153 due to a mud slide.
Map Update: Our forecasters will continue to monitor weather conditions over all of Colorado's burn areas throughout the summer.
