SPM 06-05-2019: Rivers Continue to Rise with Afternoon Storms Firing Over the Mountains

Issue Date: Wednesday, June 5th, 2019
Issue Time: 9:30AM MDT

Summary:

Similar setup occurred to the previous couple of days. Storms fired over the high terrains by early afternoon favoring the Front Range and Southeast Mountains for accumulation. Weak thunderstorms with small hail occurred over western Colorado with more intermittent coverage due to lower moisture. Isolated totals up to 0.25 were reported with most areas receiving under 0.1 inches of rainfall. A severe thunderstorms storm over the Palmer Ridge/Southeast Plains intersect in Lincoln County produced 1.25 inch and 0.6 inches of rainfall near Punkin Center. The Ellicott airport reported a gust of 25 mph with this storm. No flooding was reported as totals remained under 1 inch.

An Areal Flood Advisory continued for the Mancos River in Montezuma County for minor lowland flooding. A Flood Warning was issued for the San Antonio and Conejos Rivers in southeastern Conejos County through Thursday morning. Additional Areal Flood Advisories were issued for the Gunnison River above Grand Junction and the La Plata River at Hesperus. Minor flooding was not reported at any of these locations, though rivers remain at or slightly above bankfull.

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.
