Nothing you can do about weather forecasting unless somebody is proven to maliciously produce a false forecast to mislead. It's an imprecise science in its nature in that we only can predict a chaotic system so far based on limited precis information. Things like fog and thunderstorms are highly local knowledge based, even then the locals get it wrong sometimes. The BOM is protected from legal repercussion as you'd have airlines, shipping, graziers and a myriad of other businesses claiming billions in restitution when a bad forecast goes out. Then you'd just end up with no one wanting to do it.
