EDIT: Wednesday. Oops.
FYI this is tomorrow, prepare to get freaked out for a sec: https://www.fema.gov/press-release/20230803/fema-and-fcc-plan-nationwide-emergency-alert-test-oct-4-2023
@tankgrrl It says Wednesday. Oct 4, not Tuesday.

@tankgrrl My housemate and I appreciated it anyway. Thanks! I hadn't heard about it.

But it was better for us to put it on our calendars so it won't freak us out on Wednesday....

@tankgrrl Ha! As I am in Canada, I am free from this, except every single time there is an amber alert.
