Silly me, should have known that :oops: Perhaps this may work:

Fog=0,3
FogRand=0,3
Clouds=0,5
CloudsRand=0,5
Precip=0,5
PrecipRand=0,5
WindHeading=0,5
WindSpeed=5.000000,15.000000
WindRand=0,5
WeatherRndInterval=5,7
SeaType=0,2

Try using the comma as the seperator. Something similar what Floater's Kriegstanz Generator does in SH2.
