“A strong storm produced quarter-sized hail near the Loop-101 and SR-51 highway interchange in north Phoenix. A severe thunderstorm warning was in effect at the time. This storm also produced accumulating smaller hail and was enough to cover much of the highway interchange. This was observed on multiple ADOT webcams and led to major traffic delays. No injuries or damage were reported.”

Working a Phoenix claim from 2019?

These are aggregates. A claim file needs the per-address record: every recorded event within 1, 3 and 10 miles of the property, distances, official narratives, and citations an adjuster can check line by line. That's the report — generated in seconds, hosted on HailEvidence (the neutral evidence surface), formatted as an insurance-appeal attachment.

Provenance

Final counts: NCEI Storm Events Database, file vintage c20260527, hail events with recorded magnitude ≥1.00″ and point coordinates within 35 miles of the Phoenix anchor. NWS records are point and path observations. The absence of a nearby report does NOT prove that no hail fell at this address — it means no observation was logged nearby. A report of nearby hail documents the event; it does not by itself prove damage to a specific structure. Spotted an error? Email the address on our terms page and we correct against the source.
