To avoid as much of the fallout as possible. I suppose evacuating opposite of downwind would also be good, but less important to spell out since to evacuate opposite of downwind you would have to already be opposite of downwind. Basically don’t go closer to the blast or closer to downwind of the blast if at all possible.
Great guide. What’s the rationale behind evacuating in a direction perpendicular to downwind of the blast?
