Data
California counties
Each county has its own path (for example /sonoma or /alameda). Enter a ZIP on the home page, or open a county below. Briefings aggregate the same live sources for every county—National Weather Service (fire weather and hourly dayparts), CAL FIRE incidents when listed for that county, and other configured feeds. The map uses live CAL FIRE public GeoJSON filtered to the county. Sample mode exists only when live briefings are disabled on the server (local demos).
