According to Indian Meteorological Department, the northern limit of the southwest monsoon (NLM) continues to pass through Lat. 26°N / Long. 70°E, Barmer, Bhilwara, Dholpur, Aligarh, Meerut, Ambala and Amritsar.
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.
Under the influence of lower-level wind convergence and monsoonal easterly and southeasterly wind and a trough in westerlies in middle tropospheric levels over the region; fairly widespread rainfall very likely over Odisha, West Bengal & Sikkim, Jharkhand, Chhattisgarh and Bihar during the next 5 days.
While due to overflowing river water 50% of Ghatal, West Bengal is underwater. Locals resort to boats/canoes to commute.
Isolated heavy rainfall also likely over Odisha and Sub Himalayan West Bengal and Sikkim during next 5 days; over Chhattisgarh during 23rd to 25th, over Gangetic West Bengal, southeast Uttar Pradesh, Madhya Pradesh and Jharkhand on 23rd, and over Bihar on 26th & 27th June 2021.
Isolated Very Heavy Rainfall is also likely over Odisha on 25th and Chhattisgarh on 23rd, June 2021.
Under the influence of the strengthening of moist southwesterly winds; fairly widespread to widespread rainfall is likely over Northeast India during the next 5 days.
Isolated heavy rainfall very likely over Assam, Meghalaya and Nagaland, Manipur, Tripura, Mizoram during next 5 days and over Arunachal Pradesh on 25th June 2021.
