Based on the fire hot spot and haze covered area detected from satellite, the number of the hot spot is reducing, however, the haze covered area moving closer to the Peninsular Malaysia. I am suspecting that the current haze is contribute both by the local fire in Malaysia, as well as the thick haze from Sumatra. News reported the haze will become thicker approaching night, where the stable atmospheric condition with weak northeastery wind might help the intrusion of haze from the Sumatra Island. The haze intrusion has been reported in the news from Singapore few days back, check HERE for more detail.
