Serian, Sarawak's air pollutant index reading has improved slightly after an emergency was declared due to hazardous haze, dropping from a peak of 521 to 488. The emergency declaration was announced by the Prime Minister's Office after the Yang di-Pertuan Agong's consent. Other areas in Sarawak, including Kuching, Samarahan, and Sri Aman, also recorded very unhealthy air quality.
