11 AM NHC update shows Irma maintaining Cat-4 strength until landfall, coming ashore at at least 150 MPH winds. It could still strengthen.
Hurricane warnings shifted north too. This is a pretty slow mover too, 24-36 hours of hurricane force winds for a large area of FL.

I did a little research this morning to try and recall Hurricane Andrew (I was 21 at the time). Lowest recorded barometric pressure on record and they're saying Irma is more powerful.
On a side note, I had forgotten how bad it was for Louisiana and Mississippi for Andrew. Everyone always talks about Florida since that's where the records were broken.
