SPM 09-24-2019: Light Rainfall for the Southern Border

Issue Date: Tuesday, September 24th, 2019
Issue Time: 10:10AM MDT

Summary:

Late afternoon/early evening showers for the southern border as a shortwave moved through the southwest flow aloft. A slight increase in PW values allowed rainfall to reach the surface. It was too dry at the low levels to have any accumulation further north. Durango recorded 0.23 inches at the NWS ASOS site (KDRO) with Animas River (near Cedar Hill, NM) recording 0.28 inches at a USGS gage. Storms spread eastward throughout the evening, so the San Luis Valley also got some measurable rain. Radar indicates as much as 0.25 inches over the northeast corner of the valley with widespread totals between 0.05 and 0.15 inches. Light rain also fell over the Southeast Mountains and adjacent Southeast Plains, but totals were under 0.10 inches.

Flooding was not reported yesterday. To see estimated precipitation totals over your area the last 72-hours, scroll down to the State Precipitation 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 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.
