Federal agencies are scheduled to test warning system functions today.
The Federal Emergency Management Agency and the Federal Communication Commission are conducting a nationwide test of Wireless Emergency Alerts and Emergency Alert System.
The WEA test message will be sent to cell phones that are on, within range of an active cell tower, and connected to participating wireless systems.
Some cell phones will not receive the message and users cannot opt out of receiving the test message.
A lawsuit has been filed in a federal court in New York City, claiming the new Alert system represents an unconstitutional seizure of electronic devices.
Litigants argue that the system would allow President Trump and future presidents to disseminate propaganda.
According to the Polk County Sheriff’s Office, the tests will assess the readiness of the infrastructure for distribution of a nationwide message and determine whether improvements are necessary.
