Despite a record-setting year for flash flood warnings nationwide, Colorado is seeing its quietest flood season since 2008, per an Axios Denver analysis of data from Iowa State University's Iowa Environmental Mesonet.
By the numbers: As of Monday, the National Weather Service has issued 24 flash flood warnings in Colorado so far in 2025.
- That's down 48% from this time last year — and a dramatic 82% drop from 2023, when the state had already recorded 131 flash flood warnings.
Zoom in: El Paso County leads the state with six warnings this year.
- Larimer and Pueblo counties follow with three each.
The intrigue: Denver hasn't had any flood alerts this year. Still, the city shattered a 75-year rainfall record on March 26, logging 1.39 inches in a single day, per FOX31.
- More than half of Denver's total precipitation for 2025 fell in May alone, CBS4 reported.
The big picture: Scientists say climate change supercharges rainstorms by warming the atmosphere, allowing it to hold and dump more water. But that doesn't mean every region sees more rain every year.
What we're watching: Monsoon season in Colorado is just gearing up.
