According to meteorologists, the dusty conditions prevailed due to a combination of intense heat in northwest India over the past five days, parched soil due to the absence of rainfall and strong winds that have persisted since midnight.


"Dust concentration has gone up multiple times. The PM10 concentration rose from 140 micrograms per cubic metre at 4 am to 775 micrograms per cubic metre at 8 am. It is mainly because of strong gusty winds prevailing over the area. Dust will settle down soon," the news agency PTI quoted VK Soni, the head of the IMD's Environment Monitoring and Research Centre, as saying.


Over the past few days, the national capital has witnessed maximum temperatures soaring above the 40-degree Celsius mark, intensifying the hot weather conditions.
