NOAA Hail Data Feed

A free, machine-readable feed of NOAA Storm Prediction Center hail reports — JSON and CSV, updated every 10 minutes. Built from the same data that powers our interactive hail map and hail reports by city.

What this is: every row is a NOAA SPC Local Storm Report for hail — preliminary, unverified, in NOAA's own wording, not a final or damage-confirmed assessment. Each report is matched to the nearest PickARoofer-covered city when one is within 25 miles. Full methodology on the Data & Methodology page.
