Everyone should have a rough idea (planned and written out might be better, like Blast's Binder) of a "comprehensive" emergency plan.

If you have to evacuate, where would you go in all 4 directions? If you have to shelter-in-place, how many days of food do you have?

It doesn't matter if it's a hurricane, wildfire, blackout, or "matters of internal security", the preparedness is the same.
