From TECO: "With the help of 6,000 utility workers, we expect to restore power for essentially all customers in the coming days. Many will have power sooner; more extensive damage may take longer."
"Hillsborough and Pinellas customers - Thurs. 10/17 by 11:59 p.m."
Preparation has very little to do with the number of people that lose power. System design, to an extent does, but not preparation.
Preparation helps with the recovery time.
Apparently OP's never seen a hurricane. Two totally different storms, with different landfalls, but OP has stats!
