Yesterday’s weather across Colorado had it all – heavy rain, severe thunderstorms<\/span> including large hail and tornadoes, and snow! There’s a lot to cover this morning, starting out west:<\/p>\n The Western Slopes and Grand Valley remained under a plume of monsoonal moisture and northwest flow spinning around the upper level low, resulting in a second day of widespread<\/span>, long-duration rainfall. Heavy rain caused a debris flow in Uravan in Montrose County<\/strong> on the Southwest Slope, reported yesterday afternoon by CDOT<\/span>.<\/p>\n COLORADO HIGHWAY 141 HAD ALTERNATING TRAFFIC DUE TO MUDSLIDE CLEAN-UP BETWEEN COUNTY ROAD Y11 AND COUNTY ROAD Q12.<\/p><\/blockquote>\n A CoAgMet weather station in Bedrock, 7 miles southeast of the reported debris flow location, reported 2.05 inches in 24-hours yesterday. For this part of the state, 2.05 inches in a day is between a 25-year and 50-year Average Recurrence Interval (or 2%-4% chance of occurrence in any given year). CDOT<\/span> has reported that CO-141 since reopened.<\/p>\n While no flooding was reported, the last two days of rain in Grand Junction have broken daily records at the airport. A total of 0.47 was reported on the 18th, and 0.68 inches at the time of the following tweet from the Grand Junction WFO<\/span>. Since then, a total of 0.79 inches was reported at the airport for a 2-day total of 1.26 inches. This falls between a 2-year and 5-year rainfall event for Grand Junction.<\/p>\n The @GJAirport<\/a> has officially set new daily rainfall records for both August 18th and 19th! Yesterday we received 0.47″ which broke the old record of 0.26″ set in 1989. Today we’ve received 0.68″ (so far!) which breaks the old record of 0.60″ set in 1925! ☔ #cowx<\/a><\/p>\n — NWS<\/span> Grand Junction (@NWSGJT) August 19, 2021<\/a><\/p><\/blockquote>\n\n
