Q: Who sends CMAS alerts?
A: Most are originated by the National Weather Service. Some alerts such as Amber alerts are prompted by local law enforcement. All alerts first pass through the FEMA alerting gateway for verification and are then distributed to the mobile network.
Q: Do I have to have a smartphone to use the CMAS app?
A: Yes. Today CMAS is only available to Cellular One smartphone users via this app.
Q: What type of alerts will be made available to the public through CMAS?
A: Adverse weather conditions in the form of extreme & severe imminent threat warnings, Amber alerts, and Presidential alerts are distributed via this app. More common weather events such as severe thunderstorms and weather events which are not sudden in nature such as hurricanes and blizzards are not sent through the FEMA system and will not be delivered by this app.
Q. Will wireless customers be charged for CMAS/WEA alerts?
A. Wireless customers will not be charged for the receipt of CMAS messages.
Q. Will CMAS track a person’s location?
A. No, CMAS will not track any personally identifiable individual’s locations or personal data. This assures that authorities cannot collect any subscriber-related data. The app will access location services on your handset in order to provide you with only alerts which affect your area, but this information is not stored or retained historically.
