its all in the hands of Hashem what will happen during Jose. its in our hands with the gift of free-will to decide if we have had enough homes destroyed in Harvey & Irma together with many other public tragedies if we are all ready to do teshuva & make a final halt to all future tzaros in klal yisroel.
i.e. Hashem can stop it right now but only if we accept his wake-up calls for teshuva & finally do something about it & not just sit around watching all the tzaros go from tragic to horrific. a person today would need to be crazy to watch all this & live in denial thinking that this is all coincidence & we can just sit around without doing teshuva for the sins thats are causing these tragedies to occur
