How to read the index

Observations and storm areas are different.

Hail observations are individual public reports in the source feed. Several observations may describe one storm moving through the same area.

Distinct storm areas collapse likely duplicates using time, distance, and source-aware rules. It is an operational grouping, not a meteorological declaration.

Public reports can be delayed, corrected, clustered unevenly, or absent. Reported hail does not verify damage at a property. See the full RoofHeadsUp data methodology and limitations.
