National Oceanic and Atmospheric Administration (NOAA) All-Hazards Weather Alert Radios
Outdoor Warning Sirens are intended to notify people who are outdoors that there is a severe weather situation occurring and they should seek shelter immediately. These are not intended to warn you if you are inside your home.

Weather Radios
Hamilton County Emergency Management recommends the purchase of a NOAA weather radio to warn you of severe weather, day or night, when you are inside your home. You will want to purchase one with the Specific Area Message Encoding (SAME) feature, which means the receiver is capable of turning itself on from a silent mode when the signal for your area is sent out. These radios can be programmed for specific areas so you do not receive alerts from areas far away. Read a list of Indiana County SAME Codes by County.
