Schools in Negeri Sembilan will be closed tomorrow due to worsening haze conditions. Air quality readings from monitoring stations across the state have reached unhealthy levels. Specifically, Seremban recorded an Air Pollutant Index (API) of 189, Nilai registered 184, and Port Dickson reported an API of 170. These readings indicate a significant decline in air quality, posing health risks to students. The decision to close schools is a precautionary measure to protect the health of pupils and staff. Authorities are monitoring the situation closely and will provide updates as conditions evolve. Residents, particularly those with respiratory problems, are advised to take necessary precautions.
