When events like this happen the local stores always run out of certain emergency supplies...like plywood, water, ice, and even generators.
I think it's really up to the individual to apply common sense way ahead of time to be prepared.
But human nature as it is...many wait until the last minute...or they never experienced a storm situation before (maybe new to FL for example).
I would really like to see local governments be more proactive in setting up a couple centralized locations to provide such emergency supplies AHEAD of the storm instead of waiting until afterwards.
I will forward this suggestion at some point after we get through Matthew....it would certainly mitigate some of the 'panic' that some people experience in the days preceding the event.
