During last 24 hours, isolated rain and thundershowers occurred over parts of Punjab, Haryana, Delhi and NCR. These rain activities were due to induced Cyclonic Circulation over western parts of Rajasthan and a trough was extending from this system up till northwest Uttar Pradesh.
So, these weather activities were more prominent over northern parts of Delhi. Isolated rains were also observed over Safdarjung. Most of the regions of Delhi remained dry. However, sky turned cloudy during afternoon times.
Places over Punjab, Haryana like Patiala, Ludhiana, Ambala and Panchkula witnessed scattered rain and thundershower activities. Thus, pollutants over the regions of Punjab and Haryana subsided. The northwesterly winds which were coming from Punjab and Haryana helped in bringing down the pollutant levels. The pollutants levels which were earlier in moderate to poor category and very poor at few places has now come down to moderate category over most of the places. The Air Quality Index for now stands at 156 for Delhi, Noida, Gurugram, Greater Noida, Faridabad, Ghaziabad.
We now expect, minimums would further rise. They have already risen by two to three degrees in last 24 hours. Winters now take a backseat and summers seem to step in. Another Western Disturbance would be approaching Western Himalayas by March 11 and its induced Cyclonic Circulation would be seen over northern plains leading to rain activities. Thus, Delhi and neighbouring areas would witness light to moderate rain and thundershower activities with gusty strong winds to follow. Hailstorm is completely ruled out because vertical cloud development won’t be that strong during this time. However, pockets of Punjab and Haryana might witness hailstorm activity.
Pollution levels might increase marginally during next 24-36 hours. On the arrival of these rains, pollution levels would level down in and around satisfactory to moderate category.
