We are running an underwater campaign where everyone is an aquatic race, and most of the campaign will take place completely underwater. Call Lightning says:
"A storm cloud appears in the shape of a cylinder that is 10 feet tall with a 60-foot radius, centered on a point you can see within range directly above you. The spell fails if you can't see a point in the air where the storm cloud could appear (for example, if you are in a room that can't accommodate the cloud)."
Does this literally mean you must be able to see a point "in the air", or could this work beneath the waves?

I would rule that submarine areas could not accommodate a storm cloud.
The sticking point for me is in the example they give:
It seems to me that this spell description really wants this storm cloud to form in normal storm cloud areas, such as while out of doors. Just as a small indoor space could not accommodate a proper storm cloud, I would rule that underwater areas could not either.
