Date of Loss Weather Research
StormAuditor can help you organize and review historical weather information when researching potential dates of loss. It does not determine damage, causation, coverage, liability, or an official date of loss.
What date-of-loss research means here
When a property owner or professional needs to identify which storm plausibly affected a property, StormAuditor organizes the public weather record around that question: every qualifying storm date at the address, with estimated peak wind gust, estimated maximum hail size, warnings, and nearby reports — a historical weather report built for insurance claim research, so candidate dates can be compared on documented evidence instead of memory.
The workflow
- Run the Free Report Snapshot to confirm the record shows severe activity at the address at all.
- Browse the Date-of-Loss Database and Storm Calendar to see major storm days by state and date.
- Pull a full Weather Report ($2.99) listing every qualifying date in the screened sources and date window, with estimates and evidence.
- Check a specific day with Weather On This Date.
The honest boundary
StormAuditor organizes weather context; it does not determine damage, causation, coverage, liability, or an official date of loss. Those are determinations for qualified professionals and insurers. Every value is an estimate from public NOAA/NWS data under a published methodology.
