Nome Census Area, Alaska
Active alerts and forecasts are evaluated at the representative point shown below. Historical and climate evidence uses county-level data where available.
Representative point: Nome Census Area Census representative point, Alaska
NOAA county-coded Storm Events history is not assigned to this Alaska county-equivalent.
Alaska NWS reporting areas do not align consistently with Census borough and census-area geography. FEMA National Risk Index county-equivalent scores are shown as supplemental long-term evidence when returned, but they do not replace the rolling 2016–2025 NOAA history layer.

Recommendations.
- 01Monitor linked issuing agencies and compare source issue, validity, and expiration times before acting.
- 02Use the highest active or forecast hazard as the planning driver; do not average away a severe local threat.
- 03Prioritize preparedness for heavy rain and atmospheric rivers based on the currently confirmed score floor.
These recommendations never create, paraphrase, or override evacuation or shelter orders.

- 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.
