Issue Date: Sunday, July 25th, 2021
\nIssue Time: 10:25AM MDT<\/p>\n

Summary:<\/h3>\n

Another day with heavy rainfall, but this time the bulk of the precipitation was south of I-70 due to a cap<\/span> in place further north. Over the Urban Corridor, we enjoyed a much cooler and drier day thanks to a cold front that moved through in the morning. A couple storms tried to develop in Weld County, but they dissipated as fast as they formed. The flood day began rather early with storms kicking off over the southern high terrains just after 11AM. Storms were most widespread<\/span> over southwest Colorado, and they became stronger much earlier in the day when compared to the last few days. A storm popped near Redstone, CO just after noon, and it didn’t take much to cause a rockslide with the unstable<\/span> soils. QPE<\/span> reached up to 1.25 inches in the core of the storm according to MRMS. The Mesa Lakes SNOTEL station recorded 1.20 inches from this same storm. Dime to quarter size hail was reported with the storms that developed near Norwood, CO around 7:45PM. In total yesterday, there were 8 Flood Advisories and 12 Flood Warnings issued by the Grand Junction and Pueblo NWS<\/span> offices. Below is a list of flood reports in chronological order that they were received by flood type.<\/p>\n

The cold front sliding south also helped to generate some very heavy rainfall early in the day with training<\/span> storms over Pueblo (see the numerous<\/span> flood reports in the table above). The largest observation was 5.52 inches with another observer reporting “at least three inches in my gage”. QPE<\/span> from MRMS has up to 4.50 inches of rain falling over the area with MetStorm estimating about 4 inches. The front also generated some isolated<\/span>, but heavy rainfall producing storms over the eastern plains. The Lincoln\/Cheyenne\/Kiowa County intersect received just over 2 inches of rain for the 24-hour period according to both MRMS and Stage IV data. Unfortunately, there were no observations in this area. Finally, some evening storms developed over the Raton Ridge, which dropped just over an inch of rain.<\/p>\n

As far as burn areas, there were no reports of flooding over the FBF burn areas on Saturday though cleanup continued in Glenwood Canyon. There were Flash Flood<\/span> Warnings issued for both the Pine Gulch and Grizzly Creek burn areas. Heaviest QPE<\/span> were over the Pine Gulch and Spring Creek burn areas.<\/p>\n

\nThe map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE<\/span>) across Colorado. The map is updated daily during the operational season (May 1 – Sep 30) by 11AM. The following six layers are currently available: 24-hour, 48-hour and 72-hour total precipitation, as well as maximum 1-hour, 2-hour and 6-hour precipitation over the past 24 hour period (to estimate where flash flooding<\/span> may have occurred). The accumulation ending time is 7AM of the date shown in the bottom right corner. Also shown optionally are vulnerable fire burn areas (post 2012), which are updated throughout the season to include new, vulnerable burn areas. The home button in the top left corner resets the map to the original zoom.\n

Note: The 24-hour, 48-hour and 72-hour total precipitation do not contain bias corrections today due to errors in the CoCoRaHS<\/span> data. This means there may be underestimations in QPE<\/span> over the southwest and southeast corners of the state. <\/span><\/p>\n<\/div>\n\"\"<\/a>","protected":false},"excerpt":{"rendered":"
