Biggest monsoon surge in 5 years expected in Colorado’s mountains this weekend


DENVER (KDVR) — The biggest monsoon surge in five years is expected to arrive in Colorado’s mountains this weekend.

Meteorologist Chris Tomer says dewpoint values could run 60-65 degrees, which is high for Colorado in general. Values this high indicate available fuel for thunderstorms. 

Flash flooding is likely this weekend in the mountains, especially near burn scars.

Thursday afternoon was foreshadowing with “numerous mudslides” closing Glenwood Canyon. More than 20 people were rescued from a tunnel in the canyon after drivers got stranded in between mudslides before the interstate could be closed.

Highway 125 was shut down in Grand County from Lazy U to Willowcreek Pass around 6:30 p.m. on Friday due to a mudslide. Colorado Department of Transportation does not know when the road will reopen.

Campers, hikers, bikers, and anyone recreating in the mountains this weekend need to be prepared. Have rain gear and be ready to climb to higher ground at a moment’s notice.

If you need to drive through the mountains and get around Glenwood Canyon, here’s an alternate route:
