If making the walnut cake one day before would it need to be refrigerated due to the meringue?

Thanks so much for your answer. It's frustrating as one has only a short window to make meringue in Florida and that is in the winter months.

Thanks so much for a quick response I truly appreciate that.

Meringue is not a good choice for humid weather. It's very likely (certain??) to become chewy and not at all crisp. And you can't refrigerate meringue. There's too much humidity in the fridge and it will also turn the meringue chewy and weepy.

Ok so you can refrigerate it, it will just be a little softer I've put leftovers in fridge adn it was still pretty darned good--- do you have a covered cake dish, carrier some thing that you can put the layers with a silica packet? you lose the crispness when it in the fridge-- its crisp meringue not fluffy like a lemon meringue pie

Pam-- Don't refrigerate it --- do you have a covered cake plate? or cake Carrier? just keep it cool and if you have a little silica packet (like from shoes or a purse-- the ones that say do not eat) slip that in there to keep out any moisture. IF you can make the layers ahead and add the whip cream the day of, it will be even better
