Issue Date: Saturday, August 13th, 2022
Issue Time: 11:45 AM MDT

Summary:

Friday saw isolated to widely scattered showers and thunderstorms develop over the high terrain by late afternoon. The heaviest precipitation was confined to the southern Northwest Slope/Grand Valley/Southwest Slope, in addition to the Northern Mountains and western Front Range.

QPE data suggests amounts up to 1” were observed where storms occurred. Notable rain gauge observations include 0.70” southeast of Pagosa Springs, 0.70” near Breckenridge, and 0.64” near Steamboat Springs. No severe weather was reported, but a Flood Advisory was issued for western portions of the Cameron Peak burn scar; no flooding was reported. Additionally, a Flash Flood Warning and two Flood Advisories were issued near the Uncompahgre National Forest, but again, no flooding was reported.

If you observe flooding in your area, remember to use the “Report a Flood” page to make any flood reports when you can safely do so. For precipitation estimates in our area, check out the 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 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.
