They are toast. You have end checking, veneer delaminating, and warped rails and what appears to be glue joints separating. Reorder and store in a better spot next time.

If you have a house that has an unexpected roof leak, you might want to contact your insurance company. Otherwise, who doesn’t store in a weathertight location? Buy new doors

Oh bummer. Were you storing them in your garage? At any rate, the above are correct, you are looking at replacement. I wish you better luck with the rest of the project.

Hit the high spots with a grinder and slap on a gloppy coat of paint. They'll make fine doors for plywood storage cabinets in your cellar or garage.
