What it means for windshield replacement in Oklahoma City
Hail is one of the main causes of chipped and cracked windshields in the OKC metro, and most comprehensive policies treat it as a glass claim.
How we counted
We downloaded NOAA NCEI Storm Events detail files for 2010 to the latest release and kept every Hail event in Oklahoma, Cleveland and Canadian counties, OK. A hail day is a calendar day with at least one report in those counties. Recent months appear only after NOAA publishes them, so the current year is incomplete.
