The only mandatory evacuation in Polk Co is for trailers and mobile homes. This looks like it is going to be similar to Irma in 2017 in the FL interior, with lots of power outages.
On a personal note, I have been in the hospital for a blood infection; I was supposed to be discharged today with home health care, but that is not available, so the hospital is requiring me to ride out Milton there, with my family at home about three miles away.
Good luck and prayers for all in the path.
Hoping you will do well. I am not far from you so let me know if there is anything I can do.
