What public feeds report right now, next to the frozen screening baseline
Current NWS station observations across California, point forecasts and AirNow readings for a selected tract, shown alongside the current California UCRI score for the same geography. This is context for screening work in the Explorer. It is not emergency guidance, and it does not tell you what to do.
Station readings are point observations taken at instrument sites, which may sit miles from a tract and do not describe conditions across it. UCRI is a frozen model score for the tract, not a measurement of today. The two are different kinds of information and are never combined.

Source scope
NWS observations
Quality-controlled station observations can be delayed by upstream processing. Statewide statistics summarize the balanced configured network and are not population-weighted.
NWS point forecast and alerts
A selected tract resolves an exact forecast grid point, nearest observation station, and active alerts for the tract point.
AirNow
Data provided by AirNow.gov. Current AQI and forecasts represent the returned reporting area. They are not an in-tract monitor reading or regulatory air-quality determination. No endorsement is implied.
California UCRI
Released tract screening context is displayed beside current conditions. Weather and AQI never alter the model score, rank, confidence, or priority band.
Statewide colors are nearest-station context from quality-controlled NWS observations and are not in-tract measurements. Selecting a tract resolves its exact NWS forecast grid, nearest observation station, active point alerts, and AirNow reporting area. California UCRI is released screening context and never changes with current weather. For emergency decisions, follow official local authorities and weather.gov; active alerts are published at weather.gov/alerts and air quality at AirNow.gov.
