A national test of the emergency alert system will occur at approximately 11:20 a.m. today. All major wireless providers will send a test message at that time to all subscribers. Radio and television stations will also broadcast the alert. The backup test will occur Oct. 11.

However, you should act if you do not have LabAlert on your mobile device. LabAlert is the premiere communication method in the initial phase of an emergency. Sign up for LabAlert for your personal mobile device. Updated event information will be added to status.lbl.gov.  LabAlerts go to the entire database of devices, meaning you may occasionally receive a LabAlert that is unimportant to you. However, it is an important enough message to rise to the level of a LabAlert.
