Who knows? Some say it will take everything out, powered or not. Some say things must be turned on. Either way, it'll get the electrical grid, so unless you have some kind of generator that's unaffected, you're SOL. lol
Yeah I get it. 95 Roadmaster, K5 Blazer, 61 Utiline ,64 Dart, Starcraft boat all full of gas mostly, Gerry Cans also. Earl stuff should run lol.
Some LP bottles full, propane tree, stove and lantern. Water the problemo at least need bleach, tablets etc.
Not a worry wart but been evacuated with fires, earthquakes always a concern etc.
