Several flights to and from Delhi were delayed due to dense fog on Monday morning, but no flight was cancelled or diverted. Around 30 long and short distance Delhi trains were running late on Monday morning due to the dense fog in north India.
On Monday morning, moderate to dense fog was witnessed and there's a likelihood of partly cloudy sky and haze thereafter. The maximum and minimum temperatures are expected to be 21° and 9 degrees Celsius.
In a weather warning bulletin, isolated cold wave has also been predicted for Delhi. Rain has also been predicted for Wednesday and Thursday.
In terms of the air quality, Delhi had a “poor” day as the AQI reached 289, an improvement from Saturday’s 332 at “very poor” levels.
According to SAFAR, the air will remain in lower range of very poor to upper side of poor category for the next three days. “Moderate foggy conditions are not allowing air quality to improve. However, such conditions cannot get prolonged for long and AQI will start to improve after three days. There is a partial probability of occurrence of active western disturbance,” a SAFAR report said on Sunday.
Data according to CPCB’s central control room, meanwhile, showed NCR’s average PM2.5 and PM10 readings more than two times the safe standard on Sunday. While the average PM2.5 readings at 6pm were recorded at 128.9 micrograms per cubic metre, the average PM10 readings at the same time were 210.3 micrograms per cubic metre. The safe standard for both these ultra-fine particulates is 60 and 100 micrograms per cubic metres respectively.
Under the Graded Response Action Plan, pollution is considered ‘severe plus’ or ‘emergency’ when readings of ultrafine particulates PM2.5 or PM10 are above 300 and 500 ug/m3 respectively.
Measures listed under the emergency category are rolled out when these conditions prevail for 48 hours at a stretch.
