Monitoring area radio, TV stations, or Emergency Alert Radio should be the first action you take after hearing an outdoor siren or indoor warning. Listen for details of the emergency and then activate your Emergency Preparedness Plan if necessary. Listen for road and weather conditions, Evacuation or Shelter in Place instructions. The radio and TV Emergency Alert System (EAS) stations or Emergency Alert Radio (weather radio) will give these instructions. In addition to severe weather, there could be other types of emergencies.
