Per a law passed in 2015 every three years FEMA & the FCC must conduct a nationwide alert test on all cell phones. It will occur today at 2:20 pm and it will be loud...... You cannot opt out but you can turn your phone off or put in in Airplane mode prior to the alert. You will still get the alert but at least you won't hear it.
Your phone will emit a blaring emergency alert today - unless you do this
