Summary:<\/h3>\n

The plume of moisture that has been responsible for so much rainfall over western Colorado the last few days shifted slightly east. Not surprisingly, this also shifted the axis of heavier rainfall yesterday. The big rainfall story of the day was the interior of the San Luis Valley. CoCoRaHS<\/span> in Alamosa ranged from 0.18 to 0.40 inches, and Monte Vista had about 0.25 inches reported. Just west of La Garita, a CoCoRaHS<\/span> station picked up 1.09 inches. The QPE<\/span> from MetStorm has a hard time with underestimations in that area, so hoping the new radar data will be added soon.<\/p>\n

Looking at MRMS QPE<\/span>, which does better over the area, QPE<\/span> over Blanca Peak (Sand Dunes) was 2 inches. A nearby 2 inch CoCoRaHS<\/span> station and 1.20 inch Whiskey Creek SNOTEL observation indicate there was some very heavy rainfall over the Southeast Mountains yesterday. This definitely confirms my suspicions that MetStorm underestimated rainfall totals over the San Juan Mountains for this last 3-day event. Two Flash Flood<\/span> Warnings were issued for the Spring Creek burn area. The La Veta Mountain NWS<\/span> gage recorded 0.18 inches and Weather Underground stations in the area recorded up to 0.25 inches. So far so good over this large, problematic burn area, but it really hasn’t seen a large rainfall event yet. Daily totals in Archuleta County were just over 1 inch, so that puts the 48-hour totals somewhere between 1.5 and 2 inches for the area! To put that in context, that’s a little over half of the typical rainfall totals they see during the month of July. Storms over the San Juan Mountains also produced pea sized hail. Further north, 55 mph gusts were recorded in Glenwood Springs and Silt, which makes since with rain totals dropping off to about 0.15 to 0.25 inches. Flooding was not reported on Saturday.<\/p>\n

\nThe map below shows radar-estimated, rainfall gage-adjusted Quantitative Precipitation Estimates (QPE<\/span>) 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<\/span> 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.
