Trump and The Hurricane Maria Death Toll

The Death toll was apparently high.

Trump says it was low, and inflated for political purposes...but you know what that guy's like.

I'd guess that it's got to be pretty nonstandard to look at a six month window. But it seems that you should keep the window open however long makes sense in a particular case. Presumably there were effects resulting in loss of life longer in PR than there typically are / would have been in, say, NC or FL.
