Take it from a cabinet-maker's wife. In 1982, we had a tremendous flood in our little town in North Central Florida, with 13" of rain in one afternoon (about 3 hours). All the custom wood cabinets, including large pantry(s), etc., were threatened by incoming local flooding, and loss of part of the roof which blew off. Even with stacking concrete blocks and putting the wooden cabinets atop the blocks, they could NOT be protected, and were a total loss. Anything you want to preserve should NOT be outside! The weather just brutalizes furniture/iron left outside!
