Got an emergency alert on your phone? What it means and what to do
That loud double tone and a message you didn't sign up for. Here is what a Wireless Emergency Alert (WEA) really is, checked against FEMA, the FCC and Ready.gov. Each answer links to its source.
(Our story DON'T OPEN THE DOOR starts with a fake one: "Stay inside. Don't answer the door, even to a voice you recognize." That alert is fiction. Everything below is not.)
1. Who sent it?
Only authorized public alerting authorities: federal, state, local, tribal and territorial officials, such as the National Weather Service. They send it through FEMA's alert system (IPAWS) to the wireless carriers, which push it to phones in the area. The FCC does not send alerts; it writes the rules.
2. The 4 kinds of alert
National Alerts (only from the President or the FEMA Administrator), Imminent Threat alerts (extreme weather, disasters, active shooters), AMBER Alerts for missing children, and Public Safety Messages. Many carriers let you turn off every type except National Alerts.

3. Why it got you in a town you don't live in
Alerts follow where you are, not where your phone is registered. Every WEA-capable phone in range of the targeted towers gets it, and if you drive into the area while the alert is still active, you get it too. WEAs do not track your location; they are broadcast to everyone in the zone.

4. Why it screams twice
A WEA has a unique tone and vibration, both repeated twice, so it can't be mistaken for a text. That also helps people with hearing or vision disabilities notice it. If you're on a call, the alert waits until you hang up.
5. It's short on purpose: 360 characters max
The message shows the type and time of the alert, the action to take, and the agency that sent it, in no more than 360 characters. Do what it says first, then get details from local authorities or local news. Newer phones keep the alert for at least 24 hours.

6. It's free, and works when networks jam
You don't sign up or download anything, alerts don't count against your texting limit, and WEAs are not affected by network congestion. But your phone must be on, not in airplane mode, and connected to a tower of a carrier that takes part.
7. "Shelter in place" means this
Stay where you are. Take your emergency supply kit, go to an interior room with few windows, and if told to seal the room, cover windows, doors and vents with plastic sheeting and duct tape, cut several inches wider than each opening, taping the corners first. Long stays mean managing your water and food.
