Yes lightning is always and issue near a storm, Lightning hit an outboard on a dive boat in Florida, the Captain had one hand on the outboard and the other on the ladder, when he came to he was getting mouth to mouth. He was glad it was one of the women and not one of the gorilla divers :)

Rain will sometimes lower vis, if you are near an inlet wait for high slack tide when the ocean has flowed into the inlet stopping the outflow.
