Smart to be prepared. That is certainly possible, but unlikely in my opinion.
You’ve gotten some very bad information about hurricanes changing course. History is FULL of examples of hurricanes that have turned sharply... MORE than 90 degrees. But, they slow down first. Irma has been slowing.
She’s NOT going far into this cold air mass. Gulf Shores might still be in play.... But, no further. And, if she goes that far, NO WAY she’s Cat 5. There will be too much shear, and dry air.
You are right about course changes. Joaquin really messed with Long Island, Bahamas in 2015, wandering by it twice.
Interesting to watch.
The track has been moved westward, but has it been moved enough?
Hurricnae Harvey just being the most recent example.
