Farm fires have played a significant influence in physically pushing the NCR's air quality from bad to worse. The weather is exacerbating the situation. According to a subcommittee on Graded Response Action Plan, climatic conditions will be particularly unfavourable for pollution dispersion until November 18, and agencies involved must be fully prepared to execute steps under the 'emergency' category.

Meanwhile, SAFAR has issued a severe health warning, recommending everyone to refrain from engaging in any outside physical activity. It advised individuals not to rely on dust masks for protection and instead to utilise N-95 or P-100 respirators. Meanwhile, the country's pollution control body has advised concerned authorities to be "fully prepared" for emergency measures to address the pollution problem in the national capital.
