Montrose hail storm history
Montrose County·NOAA NCEI Storm Events Database·~75-day publication lag
Montrose County has recorded no hailstorms of 1 inch or larger in the past 10 years. This absence of significant hail events reflects the area's geographic position in southwestern Colorado, where the San Juan Mountains and higher elevation terrain create different atmospheric conditions than those found on the Front Range.
When hail does occur in the Montrose area, it follows a delayed seasonal pattern compared to lower-elevation Colorado regions. Peak hail activity occurs from June through August, with May as a secondary risk month. This 4- to 6-week delay from Front Range timing is driven by Montrose's mountain geography and the development of afternoon convective storms at higher elevations.

NOAA maintains limited reporting density for Montrose County relative to urban Colorado areas. The absence of recorded 1-inch-or-larger events over the past decade should be interpreted with awareness that smaller hail events and localized storms may not be fully captured in the national dataset.
