How does this affect Maui? For the most part, the trade winds blow the vog to the south-west of Big Island, away from Maui. But every now and then the trade winds disappear and we get Kona (named after the town of Kona on Big Island) winds blowing from the south, south-easterly (opposite direction of the trade winds) which bring the vog to Maui and the other Hawaiian Islands. Kona winds can also bring storms. We are currently in the midst of this weather pattern, The storm hasn't materialized in Kihei (just clouds and muggy weather), but it's hazy from the vog. According to KHON's weather forecast, a high pressure system and our trade winds should return tomorrow and things will start to clear up.
What to do when it's voggy? Drink lots of water and avoid exertion. If you have asthma or breathing problems, you should consider staying indoors.
