How it works

Public storm records, one clear answer.

Official NOAA reports, matched to your address and updated every morning.

Trained spotters, emergency managers, the public and weather stations report hail and damaging wind to the National Weather Service.

The Storm Prediction Center publishes each day's reports, and NOAA's Storm Data later becomes the reviewed, final record.

We measure the distance from every report to your address or service area and group reports into storm dates.

Saved service areas, alert feeds, ZIP lists with homeowner counts and printable reports.

Sourced, and checked.

Yesterday's storm reports load every morning.

Hail sizes, wind speeds and distances, explained.

Automated checks compare our results with NOAA's files.

It's free.
