New Delhi : In view of the establishment of an anti-cyclonic circulation in the lower tropospheric levels over western parts of northwest India and substantial reduction in moisture content and rainfall, the southwest monsoon withdrew from some parts of west Rajasthan and Punjab on September 28, 2020, against its normal date of September 17. The withdrawal line passes through Amritsar, Bhatinda, Hanumangarh, Bikaner, Jaisalmer and Lat. 26°N/ Long.70°E.
Conditions are becoming favourable for further withdrawal of southwest monsoon from some more parts of Rajasthan & Punjab and some parts of Haryana, Chandigarh & Delhi, Uttar Pradesh, and Madhya Pradesh during next 2-3 days.
Meanwhile, a trough runs from a cyclonic circulation over east Bihar to westcentral Bay of Bengal off Andhra Pradesh coast across Gangetic West Bengal and coastal Odisha at lower tropospheric levels, according to the National Weather Forecasting Centre of the India Meteorological Department.
Under the influence of this system:
Scattered to fairly widespread rainfall with moderate thunderstorm & lightning very likely over south peninsular India during next 3 days. Isolated heavy falls are very likely over Tamilnadu during next 2 days; over Rayalaseema, South Interior, Karnataka and Kerala on September 29, 2020, according to a PIB release.
