PLAIN-LANGUAGE INTERPRETATION

What this assessment says.

01 / CURRENT AND 14-DAYLow

No elevated active or forecast signal appears in the available evidence.

0 intersecting official alerts. Forecast guidance available for supported hazards.
02 / LONG-TERM EXPOSUREELEVATED SIGNALS

High historical or climate indices for hail.

Historical and climate indices describe planning exposure, not current conditions.
03 / EVIDENCE COVERAGE45 OF 76

Evidence layers are available across the 19 monitored hazards.

All registered sources responded. Not scored is different from zero.
HAZARD MATRIX / 19 CLASSES

Risk by hazard

Weights: active 40% · forecast 30% · history 20% · climate 10%

Scores are 0–100 decision indices, not probabilities. Rows are ordered by current or near-term signal, then high long-term exposure.

Recommendations.

  1. 01Monitor linked issuing agencies and compare source issue, validity, and expiration times before acting.
  2. 02Use the highest active or forecast hazard as the planning driver; do not average away a severe local threat.

These recommendations never create, paraphrase, or override evacuation or shelter orders.

LIMITATIONS / REQUIRED READING
  • The primary score is a confirmed 0–100 decision index, not an event probability. A technical worst-case bound remains available in component evidence when required data is missing, but it is not an expected range or forecast.
  • Source outages and unsupported hazard layers are shown as unavailable or not scored. Missing evidence is never treated as zero.
  • Days 8–14 use freely available model guidance. NOAA CPC outlooks do not provide deterministic location-level forecasts for every hazard.
  • FEMA National Risk Index values use hazard-specific source windows and are supplemental. They are never labeled as the requested rolling 10-year history.
  • Climate trend scores are county-level derived comparisons, not event forecasts. Tornado, hail, hurricane, surge, smoke, lightning-strike, blizzard, and ice-event projections remain unscored where no defensible source exists.
  • Low or unscored risk does not mean safe. Follow current instructions from the issuing authority.
