Millions of cell phones will beep, chirp and vibrate at exactly 1:18 p.m(CST). Wednesday.  Don’t panic.  The Federal Emergency Management Agency is conducting a nationwide test of its Wireless Emergency Alerts (WEA), similar to the ones conducted on radio and television. In fact, radio and TV will start broadcasting similar messages as part of its Emergency Alert System (EAS) at precisely 2:20 p.m.

“The purpose of the test is to ensure that EAS and WEA are both effective means of warning the public about emergencies, particularly those on the national level,” FEMA said in a release. Testing of public alert and warning systems helps to assess the operational readiness of alerting infrastructure and to identify any needed technological and administrative improvements.  Cell towers will broadcast the WEA test for approximately 30 minutes. Cell phones that are switched on, within range of an active cell tower, and whose wireless provider participates in WEA, should be capable of receiving the test message.  The cell phone message will have a header that reads “Presidential Alert” and the following text: “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed.”

It should appear only once.

This will be the first national test of the cell phone alerts. The system is used to warn the public about dangerous weather, missing children and other critical situations while also providing the president the capability to address the nation during a national emergency.  The exercise is being held in cooperation with the Federal Communications Commission and the National Weather Service, and with the participation of the communications industry.

A truck plowed into a crowd of protesters outside of a Flint, Michigan restaurant. The rally was set up to protest in favor of the right to form unions.  It happened Tuesday just after 7 a.m. near a McDonald’s. Several people were hurt, but an exact number and severity of injuries was not immediately available.

According the Associated Press, Police Chief Tim Johnson said he doesn’t believe the crash was intentional and that the driver “seemed pretty shaken up.” Johnson initially said four or five people had non-life-threatening injuries, but later said eight were hospitalized.  According to Gray TV affiliate WJRT, police reported that they were all awake and talking in the ambulances.

The pickup was later hit by a utility truck.  It was dark at the time of the crash.WJRT photographer Tony Zyber, who was on scene when the crash happened, said the march turned into pandemonium afterward.The AP reported that Johnson said those who were struck were at the end of a group of protesters walking along a street. He says the driver “acted like he didn’t see them.”
