SPM 08-23-2022: Mudslides for East Troublesome Burn Scar

Issue Date: Tuesday, August 23rd, 2022
Issue Time: 10:50 AM MDT

Summary:

Monday felt like a broken record as the pesky upper-level low lingered in the region, providing enough synoptic lift during daytime heating to spark showers and storms over the high terrain by shortly after noon. Precipitation coverage was more limited yesterday, with convection mainly confined to the mountains south of I-70 and west of I-25.

QPE data suggests precipitation amounts of 1-1.50” from the Central Mountains southward across the San Juans and Southeast Mountains. A National Weather Service co-op observer measured 1.15” in just over 2 hours near Rosita; other notable rain gauge observations include:

• 0.95 and 0.91” near Salida
• 0.84” near Woodland Park
• 0.72” near Buena Vista
• 0.65” near Georgetown
• 0.61” near Breckenridge

Farther north, isolated showers and storms over the Northern Mountains prompted a Flash Flood Warning and Flood Advisory for portions of Grand County, including the East Troublesome burn scar. Local law enforcement reported that Highway 125 was closed in both directions, from Trail Creek to Forest Service Road 112, due to mudslides.

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.
