The Southwest Monsoon has further advanced into remaining parts of Rajasthan, Haryana and Punjab and thus it has covered the entire country today, the 26th June 2020. Thus Monsoon has covered entire country ahead of 12 days before normal date. In 2013, Monsoon covered entire country on 16 June. IMD DG Dr M Mahapatra said that formation of a low pressure area over Bay of Bengal which moved west-northwestwards and another cyclonic circulation over central India basically helped in advance of monsoon.
Mahapatra said that the rain so far has been quite good and well distributed with 31 put of 36 meteorological subdivisions getting normal to large excess rainfall during June. Certainly, it is beneficial for sowing. June is the main sowing season for major parts of the country except some parts of Rajasthan, especially west Rajasthan. Hence, there may not be any adverse impact.
The trough at mean sea level now runs from Punjab to east Bihar across Haryana & Uttar Pradesh.
♦ Due to shift of trough northwards and convergence of strong southerly/south-westerly winds from Bay of Bengal over northeast & adjoining east India, widespread rainfall with isolated heavy to very heavy rainfall very likely to continue over northeast & adjoining east India during next 3 days. Isolated extremely heavy rainfall is also likely over Bihar, Sub-Himalayan West Bengal & Sikkim and Assam & Meghalaya during 26th-27th June.
♦ Fairly widespread to widespread rainfall with isolated heavy to very heavy rainfall likely over parts of south peninsular India during next 4-5 days. Isolated extremely heavy rainfall also likely over Kerala & Mahe during 26th-27th June.
♦ Fairly widespread to widespread rainfall activity with isolated heavy to very heavy falls also very likely over East Uttar Pradesh during next 3-4 days. Isolated heavy to very heavy rainfall also likely over West Uttar Pradesh during 28-29th June.
♦ Thunderstorm accompanied with lightning very likely at a few places over East Uttar Pradesh, Bihar and Jharkhand during next 4-5 days.
