While chump immerses himself in Alabama to the exclusion of other things the rest of the country is drowning water. Will he even notice?

He made the tweets on Sun the 1st. 
There were still forcasts that said AL could be hit. (Not with eye but damage) Trump simply told people to be prepared and listen to your local people. 
Here is what the Euro model was forcasting MON Sept 2nd, the day after Trump's tweets saying AL could be hurt. 
Notice the black line that is still touching the southeastern border of AL (this is MON the day after the tweets) 
Now look at this forcast:

Here is a map of spaghetti models from 8/29 showing AL was a possiblity. (Interesting these have been removed from American news sites....I was in process of capturing one on of the Times sites when I had to help a customer and when I returned it was gone. Why? To claim AL was never in any forcasts) 


Others on aM have said they had family in AL who were concerned about getting hit. 

He was correct. There was a chance for damage in AL being forcasted at the time.
