Ja, all the rain and clouds we've had the last couple weeks is causing the gases (hydrogen sulphide if I remember correctly) from increased production at Secunda to be 'trapped' underneath. (this seems to be the consensus) Then I assume the wind being exacerbated by the Moz storm are just pushing the gas clouds towards GP. Everyone I know is having allergy type reactions, and those of us with asthma are sucking down air a little harder... Its not great.
