Supermarket shelves across Florida have been stripped bare as panicked locals prepare for the first major hurricane to make landfall in the sunshine state in four years. Photos from the weekend showed lines of Floridians stretching back from supermarket registers through aisles stripped bare of bottled water and other essentials. Tropical Storm Ian is expected to strengthen into a hurricane on Sunday and reach 'major' hurricane strength - anything Category 3 or above - on Tuesday before it hits Cuba. The storm is expected to make landfall in Florida midweek, either late Wednesday night or early Thursday morning.
