How to read this map
- These are hail reports from storm spotters, the public, media and apps, collected by NOAA's Storm Prediction Center. They are not a measurement of every storm, and no report doesn't mean no hail.
- Places with more people tend to have more reports, so the busiest parts of town will look busier.
- Dates follow NOAA's records, which use Central Standard Time.
- The map covers 2000 through 2025, the years in NOAA's final database.
- Data: NOAA Storm Prediction Center severe weather database, filtered to Oklahoma County, Cleveland County and Canadian County, Oklahoma.
