Longmont climate and what it does to garage doors

Longmont sits at the mouth of the St. Vrain corridor, which channels strong downslope wind and gives the city noticeably harsher wind events than towns just east of it.

Wind: St. Vrain canyon outflow produces some of the strongest sustained winds on the Front Range, and wind-related door damage is a routine Longmont call.

Hail: Boulder County hail is frequent and often large; Longmont neighborhoods see clustered panel damage.

Snow and ice: Heavy upslope snow loads doors and strains older springs. Regular winter thaw days with hard refreeze overnight.
