Ha ha, very funny!!!
My MIL is 85 and lives in a retirement home here, it's on the water.
They got evacuated to a "sister" complex in Sarasota last time. She's already getting her stuff together for another trip. If the EOC gives an evacuation order, her complex moves quickly. Last time they had charter buses pick up the residents and move them by late Thursday afternoon (the evac order came at noon.)
We'd have her come stay with us (actually me and my son because hubby has to be in city operations center during a storm), but she is dependent on electricity for some of her health needs (nebulizer, etc.) and that's one sure thing we'd probably be without in the event of any kinds of winds. We live in an area with LOTS of trees.
All those pine trees out back look pretty until a hurricane threatens, then it's not such a comforting sight!
For emergencies, consider getting her a battery powered nebulizer. I use one.
Prayer heavenward for your MIL *and* your family. <><
