Regional records are context, not events at an address
NOAA Storm Events summaries show selected hail, wind, tornado, tropical storm and winter storm event types for a matching county. When a unique county or retained county records are unavailable, a state fallback is explicitly labeled; county and state totals are never combined.
- Event records are not necessarily independent storms. A reported start-day count is also not a storm-frequency rate.
- County summaries exclude forecast-zone-only records; state summaries include broader reporting geographies.
- Reported property damage is nominal USD, not insured losses or claims for this property. Unknown amounts and absent years remain distinct from reported zero.
- The default six-year window ends at the imported NOAA snapshot, currently through March 2026; partial years are labeled, not extrapolated.
Point-matched footprints are a separate historical check
The NOAA Event Footprint Catalog supplies mapped historical hail and tornado polygons. TrueViewly checks exact point coverage with no nearby buffer and retains dated source-record references. A match is not proof of building damage or a property claim.
- Hail polygons can represent hourly radar-derived intensity swaths, not independent storms or measured hail sizes at a building.
- Tornado footprints describe retained historical mapped areas; they do not predict the next tornado.
- UTC and convective dates can differ. The most recent matching polygons are shown in a capped list, with truncation labeled.
- A no-match is not evidence of zero hazard, complete observations or insurance eligibility.
Read each source period and availability state
The prepared footprint snapshot includes tornado annual files from 2010 through partial 2026 and hail from October 14, 2020 through October 7, 2026. Missing requested dates are disclosed. Report generation does not advance those source periods.
- Full acquired source scope does not guarantee observations in every state or territory. Geographic, temporal and observational coverage are different.
- A California-only package is not assessed outside California; limited-year packages retain their explicit time scope.
- Unavailable source lookups, no retained records and no polygon match are distinct states, none silently converted to zero risk.
- These are saved historical snapshots, not live severe-weather alerts or an emergency monitoring service.
Use the evidence for verification, not automated underwriting
The validated Sonoma sample shows one county hail record in 2021, with a recorded zero damage amount, and no retained footprint covering the point. That does not contradict nearby SPC reports used by the existing score: the sources, geographies and periods differ.
- Regional NOAA summaries and point-matched footprints do not change the current module scores, weights or overall score.
- Review available roof inspections, repair records, disclosures and mitigation measures rather than assigning a storm or claim to the building.
- Confirm current policy terms, deductibles, exclusions and eligibility with an insurance professional. TrueViewly is not a loss model, quote or underwriting determination.
Sources and further reading
Source publications and live agency pages may differ from the snapshot used in a report. Check the report's source dates and confirm material findings through the responsible authority.
Frequently asked questions
Does a footprint match prove my building was damaged?
No. It is mapped historical source evidence covering a point, not a building inspection, verified claim or damage determination.
Why can the score show nearby storms but no footprint match?
Scoring history uses separate nearby reporting radii and source periods. A footprint check requires a retained polygon to cover the exact point. Those results can legitimately differ.
Do these new panels change scores?
No. Regional NOAA history and retained footprint matches remain contextual evidence, separate from existing scoring inputs.
Does no match mean no storm exposure?
No. Missing observations, source dates and footprint coverage can prevent a match. No match must not be treated as zero hazard.
