The idea here is storms that happen periodically within the story’s narrative / timeline that help to uncover new crash sites, scattered crates, valuable information. Storms could even create temporary under currents or strengthen the ones that already exist increasing power output (or temporarily disabling) turbines. Shifting debris could uncover new areas to explore within the game. Could even include waterspouts or whirlpools or like in Greek Mythology the storm could awaken the Great Maw of the sea which is actually a creature that creates a giant whirlpool, that would be a scary site.
