Warning Procedures and Information

Warning Sirens And Procedures

A monthly test of the Emergency Alert System (EAS) and warning sirens is conducted at 11:45 am on the first State work day of each month. This consists of a 50 second steady tone with a 20 second break followed by a 50 second wailing tone.

During a natural disaster, a steady three-minute siren tone is the attention alert signal. When the siren is heard, tune your radio or television to any local station and listen for emergency information and instructions. Listen to EAS broadcasts for further instructions and the all-clear announcement.  

During an man made attack, a wailing three-minute siren tone is the attention alert signal.  When the siren is heard, "Get inside, Stay Inside, Stay tuned."  As practical as possible enter a structure, be prepared to spend 14 days within that structure, and stay tuned to your radio, television of any local station and listen for emergency information and instructions.  Listen to EAS broadcasts for futher instructions and the all-clear announcement.

Information Access

The EAS will provide you with the information you need. Emergency instructions are broadcast over radio, television, and cable television systems. Tune to your local station when you hear the warning sirens and do not use the telephone except for serious emergencies.
