The biggest mystery in these terms is Sanibel, Captiva and Pine Island. They had a mandatory evac ordered, but invariably there are people who stay behind. However, with the Sanibel causeway down, EMS cannot easily get teams on the ground to check. I suspect they are using drones to fly over and initially look for signs of survivors or loss of life.
Which brings me to this observation: drones are a Godsend in situations like these. So much safer and more efficient for emergency services to be able to assess ground conditions before having to go in with boots on the ground.
I have a customer who moved down to Sanibel permanently during the pandemic. I texted her a couple of days before to wish them luck in the storm. I heard from her about 30 minutes ago...she said they have no idea when they'll be able to get back on the island, but have heard that the damage is catastrophic. I can't imagine .
