Issue Time: 10:55 AM MDT

Summary:

Sunday featured an uptick in precipitation across the state compared to Saturday, although showers and storms were mainly limited to the mountains along and south of I-70.

QPE data suggests amounts of 0.50-1.00” from the Central Mountains southward into the San Juans, Southeast Mountains, and Southwest Slope. Flood Advisories were issued for portions of San Miguel and Dolores Counties, but no flooding was reported. Notable rainfall totals include 1.04” and 0.67” near Durango and 0.50” near Paonia Reservoir. A Severe Thunderstorm Warning was also issued for portions of Garfield County, but no severe weather was reported there.

Farther north into the Northern Mountains, precipitation totals were lower, with generally 0.50” or less. 0.47” was measured by a rain gauge near Gypsum. A Flood Advisory and Flash Flood Warning were issued for portions of the East Troublesome burn scar, but no flooding was reported. To the west of East Troublesome near Steamboat Springs, 0.25” hail was reported by the public.

Out west in the Grand Valley near the Utah border, non-thunderstorm gusty winds up to and exceeding 60 mph were measured by several weather stations.

No flooding was reported on Sunday. For precipitation estimates in our area, check out the map below. Remember, if you observe flooding in your area you can use the “Report a Flood” page to make a flood report, when you can safely do so.

Denver’s radar is down for maintenance upgrades through the end of August. QPE may be underestimated across the region.

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.
