Images from areas hit by Hurricane Ian show how quickly the historic storm swamped Florida.

Ian, now a tropical storm, submerged a hotel pool in Sanibel Island, Florida, in under an hour, as seen in video taken by WFTX reporter Elyse Chengery.

Additionally, footage taken by Loni Architects showed the rapidly deteriorating conditions in Fort Meyers, which took a brutal blow from the storm.

Ian destroyed a section of the Sanibel Causeway, which connects Sanibel Island and Captiva with mainland Florida, preventing all access for ground vehicles.
