Disputing a claim at a Monona address?
This page covers the city. A claim dispute needs the record around your address: every NWS-recorded event within 1, 3 and 10 miles, the disputed date highlighted, citations formatted for an insurance appeal.
Verify an address — $29NWS 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.
