Many people are in this situation. Even those with satellite TV and satellite radio won't receive local emergency alert system (EAS) messages since they only broadcast national EAS activation from the President. So if you wanted to receive flash flood, tornado, hazardous materials, AMBER alerts, or other local warnings you wouldn't get them.
There are two solutions, however. You can purchase a NOAA All-Hazards Weather Radio, which even if you have local TV and radio is the most efficient and direct way to get EAS messages. These radios cost between $15 and $50 and are available locally at several retailers. Learn more at the Emergency Management page.
Another option is to sign up for Nixle. This system allows us to broadcast emergency messages over email and SMS (cell phone text messages) to those that sign up and list their location as being in Teton County. You can enroll in this service online.
