Snowing underwater?
 

Playing R'leh I got the 'Heavy snowfall has blocked trade routes' event in my capital. Perhaps this could be changed to 'Ice forming on the surface of the ocean has blocked the sunlight for the crops below' or something similar.

They are obviously not talking about "heavy snowfall", but instead a fall of "heavy snow" - i.e. frozen dideuterium oxide or heavy water. Being heavy this snow will of course sink to the bottom and block the subsea tradeways.(*)

(*) Okay, so it's not that heavy; but hey - maybe it's magical dideuterium oxide snow! Or maybe it's particularly heavy in dominions with positive sloth. Or...

I like snow, but I'd certainly stay indoors if it was snowing ditritium oxide. The freezing point of salt water is depressed (and heavy water freezes at a higher temperature anyway), so heavy freshwater snowflakes could possibly remain frozen and intact while falling through cold, light saltwater.
