How a stream works

  1. Public sources, every 10 minutesNWS issues the alert, USGS logs the quake, CAMS measures the air. We read them as they publish and keep one deduplicated record per alert.
  2. One stream per placeA state or a county gets its own page, JSON and RSS. Agents read the same stream people do.
  3. One mission per alertA flood warning suggests clearing a storm grate; a heat warning suggests a car-free day. Finish it on the iChallenge arena for your state and it is counted.
  4. Honest by designAlerts are relayed as issued, with the source on every card. We add the action, never the drama.
