I don't see any problem betting on the weather. I don't even mind if weather agencies and bureaus are giving forecasts every hour of the day. They are mostly wrong anyway. With all their knowledge, equipment, charts, etc. it seems their predictions are not much different from gamblers' predictions.

I remembered our local weather bureau reminding us to bring our umbrellas during the day because there's a high chance of rain. There was no rain but they were so right about the umbrellas. The sun was angry.
