Fort Collins hail storm history
Larimer County·NOAA NCEI Storm Events Database·~75-day publication lag
Fort Collins lies in Larimer County on Colorado's Front Range, where afternoon convective storms tracking northeast from the Rocky Mountains create a natural corridor for hail formation. The city's elevation and geography make it particularly exposed to hail-producing thunderstorms during the spring and summer months, when warm, moist air collides with cold upper-level systems over the Continental Divide.
Check if your roof was damaged by recent hail
Hail risk in Fort Collins peaks from May through July, when afternoon storms between 2pm and 7pm MT most commonly develop severe characteristics. Secondary activity occurs in April and August. The Front Range topography accelerates storm development along this corridor, making the May-to-July window the period when homeowners should prioritize roof inspections and ensure adequate insurance coverage.
