There is a high potential for flash flooding today across much of south central and southeast Colorado. Can't stress this enough...Do not drive into flood waters! The road could be washed out and fast flowing water can easily sweep you away. #cowx pic.twitter.com/YNyLcWmn8f— NWS Pueblo (@NWSPueblo) July 31, 2021

A Flash Flood Watch remains in effect for portions of mountains and valleys of southern Colorado, which includes the Interstate 25 corridor. The weather watch expires 1 a.m. Sunday.
Monsoon moisture and moist upslope flow behind a cold front is bringing the threat of widespread heavy rain, which is likely to cause flash flooding in the region.
A Flash Flood Watch is issued until Sunday at 12 a.m. for portions of northwest Colorado and west central Colorado, including Elkhead and Park Mountains, Grand and Battlement Mesas, and West Elk and Sawatch Mountains.
The monsoonal moisture remains entrenched over portions of west central and northern Colorado mountains. This will lead to multiple rounds of afternoon thunderstorms capable of producing heavy rainfall. Several areas have received heavy rainfall the past few days and additional amounts could lead to excess runoff and localized flash flooding.
