Monsoon Watch & It’s Farewell

This is a tradition of IMD that before declaring withdrawal of Southwest monsoon from any part of the country, they declare that monsoon trough less marked. So on 27^th September south west monsoon trough has been less marked. Before 27^th it was at the foot hills of Himalayas. The well marked low over northern part of central MP on 21^st which moved up to West UP and Uttarakhand did not allow IMD to declare the withdrawal of monsoon. Though it was confirmed that this low would not move west ward because of anticyclone present over west Rajasthan. On 27^th September IMD declared withdrawal of south west monsoon from West Rajasthan, parts of Punjab, parts of Haryana and Kutch.
