Weather forecasting

I filmed Richard explaining how to forecast the weather using seaweed. Unfortunately what with the thundering of the waterfall, the roar of the sea and the howling of the wind he was completely drowned out! So here is what I remember.

If the seaweed is wet it's raining
If the seaweed is dry it's not raining
If you can't find the seaweed it's windy
If you can't see the seaweed it's misty
If the seaweed is white then it's snowing
