New Delhi, Oct 18 (IANS): Heavy rainfall accompanied by thunderstorm lashed parts of Delhi-NCR on Monday which led to a decline in temperature and further deteriorated the air quality.
According to the India Meteorological Department (IMD), thunderstorms with moderate intensity rain with heavy intensity rain over isolated places would continue to occur over and adjoining areas of the national capital during the next two hours.
"Thunderstorm with moderate intensity rain with heavy intensity rain over isolated places would continue to occur over and adjoining areas of entire Delhi, Gurugram, Aurangabad, Palwal, Faridabad, Ballabhgarh, Panipat, Sohana (Haryana) during next two hours (issued at 4 a.m.)," the IMD tweeted.
