Summary:
Continued moisture transport from the west primed Colorado for another active weather day yesterday, especially along and west of the Continental Divide where precipitable water values were well above average. Due to this elevated moisture, widespread thunderstorms over the high country were efficient rainfall producers. The locally heavy rainfall resulted in the following reports:
Debris Flow: I-70 closed in two locations in Garfield County due to mudslides
Flash Flood: Water shut down traffic on Highway 92 East 3 miles ENE of Delta (Delta County)
Flash Flood: 3 miles WNW of Redlands (Mesa County)
Debris Flow: Water and mud were reported across Highway 145 near Sawpit (San Miguel County)
More widely scattered coverage occurred east of the mountains where moisture was a bit below average, with the main impacts being gusty winds and brief heavy rainfall. For a look at precipitation estimates in your area, please see the State Precipitation Map below.

The map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE) 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 may have occurred). The 24-hour, 48-hour and 72-hour total precipitation contain bias corrections that are not disaggregated into the hourly estimates, so there will likely be some differences. 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.
