What this document is not

It is not an expert report or a signed technical opinion. It is documentation of public federal data, with source, time and evidence level stated. A professional interprets the damage.

Every event shown is radar-indicated, never confirmed. Measured cell-by-cell precision is 36%. The method does not measure hail size (measured correlation r=0.31). That is why we do not publish inches as if they were size.
