SPM 09-30-2022: Rain for Northwestern Portions of State

Issue Date: Friday, September 30th, 2022
Issue Time: 10:15 AM MDT


High elevation showers and storms developed by early afternoon on Thursday, with the heaviest precipitation falling over northwestern portions of the state roughly along and west of I-25 and along and north of I-70. In this region, QPE data and rain gauge observations suggest that amounts up to 0.50” were observed under the most intense cells. Notable rain gauge observations include:

• 0.45” near Trappers Lake
• 0.44” near Glenwood Springs
• 0.40” north of Glenwood Springs
• 0.33” near Kremmling

QPE data suggests isolated lighter amounts of 0.25” or less across portions of the San Juans, southern Front Range/Urban Corridor, Palmer Ridge, Northeast Plains, and Southeast Mountains.

Looking at the U.S. Drought Monitor updated yesterday morning, we see a further reduction in moderate, severe, and extreme drought conditions (by percent area) across the state compared to last week, while the percent area of exceptional drought conditions remained unchanged.

No flooding was reported yesterday. 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.

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.
