Historical Colorado Flooding Continues

The amount of rain across north central Colorado has exceeded 12 inches over the last 7 days in many areas.

Boulder has beared the brunt of the massive rainfall. The Community Collaborative Rain, Hail and Snow Network in Colorado had this to say about the historic rainfall for Boulder:

"Boulder's annual precipitation averages 20.68 inches, with an average of 1.68 inches in September. For September 1-13, the U.S. Cooperative Weather Station in Boulder has received 14.74 inches of rain. This nearly three times the previous monthly September record of 5.50 inches in 1940! This is also the wettest month ever on record for Boulder. The previous record was 9.59 inches in July 1995."

The CoCoRaHS cooperative network reported 24 location with more than a foot of rain from the 9th through the 14th.

The river levels are not forecasted to fall below current levels for days. Moderate to extreme flooding will continue through the middle of the week. Below are the gauge reports from the Colorado Division of Water Resources.

Luckily, the 5 day rainfall forecast will give Colorado a significant break this week.
