Don't be alarmed as an "Alert Ready" emergency system TEST will sound across Canada today (Wednesday, November 17).
Here in Alberta, the alert will go out at 1:55 p.m.
It will be heard on mobile devices, websites, social media, TVs, and radios.
The Alert Ready is tested twice a year in May and November.
The system is used in case of emergencies like floods, fires, and amber alerts, and it has an accompanying app called Alberta Emergency Alert.
Phones set to silent will show the message, but the alert sound won't play.
