NOAA Weather Radio Alerts

NOAA Weather Radio broadcasts 24/7 with forecasts, current weather conditions, and climate information. During severe weather, normal programming is interrupted with emergency broadcasts. Many emergency messages will automatically turn on weather radios and broadcast the emergency bulletin. The following is a list of alerts that will automatically alarm "specific area message encoding" (SAME) alert weather radios.
