How Huerfano County floods

Flash flooding from summer thunderstorms dominates the flood risk profile in Huerfano County, accounting for 61 of the last 30 years' 73 recorded flood events, compared to 12 standard floods.

Recent weather patterns illustrate this hazard. On June 9, 2024, a stalled boundary over the plains produced heavy rainfall and flash flooding across Huerfano and Pueblo Counties. Earlier, on July 11, 2022, rainfall amounts approaching two inches in a short timeframe caused flash flooding and debris flows across multiple burn scars. Heavy

From the storm reports

Flash Flood · Jun 9, 2024. A boundary stalled out over the plains and resulted in the development of strong storms. Heavy rainfall from thunderstorms produced some flash flooding in Huerfano and Pueblo Counties. Isolated stronger storms (sub-severe) also developed further west over Saguache County, resulting in some hail (below severe criteria) and a brief landspout was also reported.

Flash Flood · Jul 11, 2022. Strongest thunderstorm development with the heaviest rainfall on this day was focused over and near the higher terrain. Highest rainfall amounts approaching two inches in a short amount of time caused flash flooding and debris flows across multiple burn scars.

Flash Flood · Aug 7, 2022. Numerous heavy rains and severe thunderstorms developed all across the region during the afternoon and evening of August 7th. Numerous flash floods, mud and debris slides, and damaging winds and hail were all reported as storms moved from the central mountains onto the eastern CO plains.

Flash Flood · Jul 31, 2021. The combination of the monsoon plume and moist low level upslope flow allowed for thunderstorms with heavy rainfall and flash flooding to occur on this day across the region. The highest concern for flash flooding was over the mountains and I-25 corridor region, but later in the evening, additional flash flooding occurred along and south of Highway 50.

Flood insurance in Huerfano County

If a building in Huerfano County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
