@samhenrigold local? national? other?

Your solution (especially with the collapse of Twitter & unreliability of FB) will likely be limited to multi pronged OSINT for the foreseeable future.

It'll also be easier the more urban your area.

Check openmhz for the US - many places also have discord or other chats set up for first responders. Most of these are not locked for viewing & you can configure push notifications.

It's work, and it's not simple - but you can get what you want.

Good luck.
