People want to shit on people in the northeast being worried about a category 1 hurricane but the city just isn't prepared for something like this. There were some statistics released a while ago that said at any one time there is only enough food in manhattan to feed everyone for 4-5 days if shit goes south, possibly less. The subways are completely flooded with water, sewage, and garbage. Entire streets in areas are flooded with sewage runoff. People are stuck in apartment buildings 40 floors up with no electricity or water.
There's only so much you can do here to prep for this sort of thing when there are 2000000 trying to prep with the same shit as you in a such a small area when you get word of something coming.
