Central Water Commission Upper Ganga Basin Organisation, Lucknow Daily Flood Situation Report Cum Advisories Date: 19 JUNE, 2021 FSR No.19 Dated: 19-06-2021 1. Weather forecast by IMD I. SYNOPTIC SITUATION: ♦ Southwest monsoon has further advanced into remaining parts of north Arabian Sea, Saurashtra, Gujarat region & Madhya Pradesh, entire Kutch, some more parts of Rajasthan and west Uttar Pradesh today, the 19th June 2021. ♦ The northern Limit of southwest monsoon (NLM) now passes through Lat. 26°N / Long. 70°E, Barmer, Bhilwara, Dholpur, Aligarh, Meerut, Ambala and Amritsar as on today, the 19th June 2021. ♦ Further advance of southwest monsoon into remaining parts of Rajasthan, west Uttar Pradesh, Haryana, Chandigarh & Delhi and Punjab is likely to be slow as large scale features are not favourable and the forecast wind pattern by the numerical models do not indicate any favourable condition for sustained rainfall over the region during the forecast period. ♦ The Low pressure area over southeast Uttar Pradesh & neighbourhood with the associated cyclonic circulation extending upto mid tropospheric levels persists. ♦ The trough from West Rajasthan to northeast Bay of Bengal across south Haryana, center of low pressure area over southeast Uttar Pradesh, Jharkhand and Gangetic West Bengal extending upto 0.9 km above mean sea level persists. ♦ The Western Disturbance as a trough in mid & upper tropospheric westerlies with its axis at 5.8 km above mean sea level roughly along Long. 72°E to the north of Lat. 25°N persists. ♦ The cyclonic circulation over south Pakistan & neighbourhood now lies over southwest Rajasthan & neighbourhood between 1.5 km & 7.6 km above mean sea level tilting southwestwards with height. ♦ The cyclonic circulation over north Rajasthan & neighbourhood now lies over south Haryana & neighbourhood at 0.9 km above mean sea level.
