Emergency Alert System in Teton County is tested by the National Weather Service every Wednesday between 11 a.m. and 1 p.m., as long as there is no severe weather in the area.
The EAS is a nationwide network designed to inform and give instructions to the public before, during, and after disasters. At the federal level, only the President has the authority to enact a nationwide EAS broadcast, and he delegates that authority to the head of Federal Emergency Management Agency (FEMA). If a nationwide activation ever occurred, you would receive the EAS message the same way you do for local EAS activation.
What Citizens Can Do
First, make sure that you have multiple methods to receive EAS broadcasts. These can be a reliable AM / FM radio, television (not satellite), or a NOAA All-Hazards Weather Radio. Many times for smaller scale events (such as winter weather shutting down highways) radio, NOAA All-Hazards Weather Radio, and television will be the only systems that will be used to notify the public. Other elements such as sirens, emergency vehicles, and highway signs are usually used for larger scale or more imminent disasters.
If you receive an EAS broadcast, listen carefully. Be sure that it affects your geographic area, then be sure to follow any instructions given. These can be evacuation orders including routes to take, instructions on how to shelter-in-place, directions to Red Cross shelters, or information related to the disaster or pending disaster.
