Is it rain proof?

We get some strong rain/winds and so far, so good. We do get some water leakage from the bottom where the doors are at since there is no weather strip at the bottom of the doors. It generally happens when we get a combination of heavy rain and strong winds. If you're concerned about water, then I would either just not let those things you're concerned about sit directly on the floor or close to the door (put it further in back). We have a 3-shelf wire rack inside, lawnmower and other misc yard stuff stored inside. The only things we have sitting directly on the floor are the shelf, the lawnmower and some buckets. Hope this helps!

This unit is weather resistant.
