El Paso County·NOAA NCEI Storm Events Database·~75-day publication lag

Fountain, located in El Paso County on Colorado's Front Range, sits directly in a corridor where afternoon convective storms track northeast from the Rocky Mountains. This geographic position places the city in a zone of concentrated hail risk during the warm season, when atmospheric instability and wind shear favor the development of severe thunderstorms capable of producing large hail.
