NOAA representative observed events

County-coded observed-event types and dates from NOAA NCEI Storm Events.

Practical preparedness implications

These actions translate record categories into low-regret planning steps. They are not predictions and do not replace local emergency instructions.

  1. Priority 1

    Prepare for observed high wind events

    High Wind is the most frequently reported NOAA hazard type among 134 exact county-coded observed events in this profile.

    • Review household alerts, evacuation routes, and insurance coverage for this hazard.
    • Keep a documented communication and reunification plan that works during power or cellular outages.

    Evidence sections: NOAA observed events

  2. Priority 2

    Review declared winter storm history

    Winter Storm is the most frequent hazard category among 24 unique exact-county FEMA declarations in this profile.

    • Review insurance, documentation, and recovery contacts relevant to this declaration category.
    • Learn which local and state assistance channels operate before any federal declaration is made.

    Evidence sections: FEMA declarations

  3. Priority 3

    Use July as a readiness checkpoint

    NOAA records place 33 observed county events in July, the profile's highest observed monthly count.

    • Before this historically high-count month, refresh supplies, medications, contact lists, and alert settings.
    • Recheck transportation and shelter options for people, pets, and accessibility needs.

    Evidence sections: NOAA observed events

  4. Priority 4

    Plan from both observed and declared history

    NOAA event reports describe observed local frequency, while FEMA declarations identify a narrower administrative record of incidents receiving federal declarations.

    • Do not treat the absence of a FEMA declaration as evidence that a damaging local event cannot occur.
    • After an incident, preserve photos, receipts, policy records, and official notices for local, state, insurance, and possible federal processes.

    Evidence sections: FEMA declarations and NOAA observed events

Methodology and profile limitations

A source-separated county history using exact OpenFEMA county designations and NOAA county-coded observed events.

Counting rules

  • FEMA counts one declaration per unique disasterNumber for exact county designations dated 1964 or later.
  • NOAA counts one unique EVENT_ID only when CZ_TYPE=C and the constructed state-plus-county FIPS matches exactly, from 1996 onward.
  • Statewide-only FEMA rows, NOAA forecast zones, and NOAA marine zones are excluded from county metrics.

Comparison rules

  • Each county is compared only with the median of the same source and metric across every county equivalent in its state.
  • The New York baseline contains every compatible county equivalent, including zero-count counties if any.

Limitations

  • This atlas publishes source-separated historical records, not a probability of future loss.
  • Records can be revised by their issuing agencies; regeneration selects the newest official NOAA revision for every year.
  • Statewide-only FEMA declarations are disclosed but excluded from exact county metrics.
  • Observed history is not a forecast or modeled risk score.
  • FEMA declarations and NOAA event reports measure different phenomena and are never merged into one event total.

Sources, coverage, and limitations

Each official dataset retains its own meaning, coverage period, freshness, and limitations.

Coverage notes

  • OpenFEMA v2 exact county designations from 1964 onward; disasterNumber is the unique declaration key.
  • Statewide-only, tribal, and other non-county designations are excluded from county metrics and medians.
  • Current Census county-equivalent FIPS define state comparison baselines; obsolete historical county codes are not reassigned.
  • County-level designation history is most consistently available from 1964 onward.
  • A declaration can designate multiple counties; each designation is a source record, not a separate physical event.

Limitations

  • Federal declarations are administrative actions and do not enumerate every damaging local incident.
  • Statewide-only and tribal designations are intentionally excluded from exact-county counts.
  • Federal declarations are administrative Stafford Act actions and do not capture every damaging local event.
  • Declaration counts should not be presented as forecasts or direct probabilities of future loss.

Coverage notes

  • NCEI Storm Events details files for every year from 1996 through the current available year.
  • Only exact county-coded CZ_TYPE=C records are counted; forecast-zone and marine-zone records are excluded and disclosed.
  • Current Census county-equivalent FIPS define state comparison baselines; obsolete historical county codes are not reassigned.
  • Every state summary and county profile uses this same selected-national-corpus coverage window; a state or county need not have an event on the final date.
  • 15 optional damage cells contained a bare K/M/B suffix; those amounts are retained as unknown/null and are never inferred as zero.
  • 1 record had an unrecognized CZ_TYPE and was excluded because it could not be assigned to an exact county geography.
  • The 2026 shard is preliminary; national coverage ends at the latest accepted county event anywhere in the selected official corpus.
  • Comparable all-event statistics begin in 1996; earlier reporting eras cover only a subset of event types.
  • County profiles count only exact county-coded CZ_TYPE=C records; forecast-zone and marine-zone records are excluded.
  • Finalized Storm Events records typically lag the event month by about 75 to 90 days.

Limitations

  • Storm Events reports are not a complete loss inventory and reporting practices vary over time.
  • Forecast-zone and marine-zone records are excluded because they cannot be assigned exactly to one county.
  • 15 optional archive damage cells contained only a K/M/B suffix, so their dollar amounts remain unknown/null rather than inferred.
  • 1 archive record with an unrecognized CZ_TYPE was excluded rather than attributed to a county.
  • The current-year file is preliminary through the latest event present in its selected official revision.
  • Storm Events is a report database; reporting practices and included event types change over time.
  • Damage estimates and narratives may be incomplete and should retain their source-level caveats.
