Storm Reports
Storm Report Database Guide: Hail, Wind, Tornado, Flood, and Damage Reports
How storm report databases are used, what reports can and cannot prove, and why duplicate or delayed reports happen.
Quick answer: Storm report databases collect tornado, hail, wind, flood, and damage reports that help document severe weather events.
Report sources
Reports can come from trained spotters, emergency managers, media, public submissions, radar context, and damage surveys.
Quality varies by source and event.
Limitations
A missing report does not prove nothing happened, and duplicate reports can describe the same damage.
Population density affects how many reports are received.
How to read
Use reports with radar, warnings, photos, and official summaries.
Reports are evidence, not always final verification.
