A friend of mine from the CentOS community is extremely close to several northern CA fires.

Once things die down (he was evacuated last week), he and I are planning on investigating various CentOS / nix public safety tools for future events like this.
Any suggestions in this area would be greatly appreciate. I just recently found out at Sahana, and if there is anything else along those lines, I'd be very grateful.
