About these alerts
- Straight from the National Weather Service's CAP alert feed (api.weather.gov), refreshed every two minutes. Only actual alerts are shown, not tests or exercises.
- The EAS code is the event code in the alert's SAME header (for example TOR, SVR, FFW). Alerts the Weather Service doesn't send over EAS, such as most advisories, show "not sent over EAS".
- Whether your station relays an alert depends on your state EAS plan and how your decoder is set up.
Alert text is from the National Weather Service. Not a product of the NWS or the FCC.
