Well Harvey just nailed(and is still nailing) Texas as a Cat 4. First major hurricane to hit the US since '05 and the first Category 4 since '04.
From what I've been hearing from sites and chasers, they are saying widespread destruction already and many places are still in the eyewall right now.
After it finally weakens, it will drop 30-60 inches of rain, then possibly move back over the gulf, possibly restrengthen and hit Texas again or LA.
This will go down in the history books.
