About these numbers
Every figure on this page comes from the NOAA Storm Prediction Center Local Storm Reports file, matched to reports within 25 miles of the city center. Reports are preliminary: they come from trained spotters, emergency managers, the public and mPING app submissions, and sizes are often estimated against a coin or ball. We do not adjust them. A roofer tagged Verified holds a license or registration we confirmed in a public registry. That tag says nothing about coverage, so ask whoever you pick for a current certificate of insurance before signing.
