Summary:<\/h3>\n

With the moisture plume in place, there was another round of rainfall oriented from southwest to northeast again. A little better moisture was in place, but over the mountains, limited instability allowed rain rates to stay low enough that there was little flooding reported. The highest totals over the Front Range were just under 0.75 inches. We’ve been keeping our eye on the the San Juan Mountains, as a multi-day rainfall event begins. The western portions picked up widespread<\/span> totals of 0.75 inches to more isolate 1.50 inches on south facing slopes. An areal flood advisory was issued just before 6PM for the Uncompahgre Wilderness Area due to rock slides being reported onto roadways. Observations in the area ranged from about 0.80 inches to up to 2 inches! With more rain coming today and tonight, there’s an increased risk for mud flows and rapid rises in local streams\/creeks. Streams in the area were already showing high flows (see the South Fork San Miguel River near Ophir below), which means some soils could already be saturated before today’s rainfall even begins (runoff).

Training<\/span> storms again produced high totals over the Northeast Plains, thankfully not directly over Wray AND slightly lower totals for Colorado. The heaviest rainfall from the storms was just over the border in Nebraska where about 4.5 inches of rain fell in the core (not shown below). A CoCoRaHS<\/span> station in Phillips County observed 1.01 inches. Flooding was not reported on Friday.<\/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.
