Withdrawal of Monsoon begins from West Rajasthan | Today’s news
The southwest monsoon has started withdrawing from parts of northwest India, with a line of withdrawal moving across western Rajasthan and adjoining areas, the India Meteorological Department (IMD) said on Sunday.
As of September 20, the line of withdrawal passes through Ramgarh, Mohangarh, Phalodi and Khajuwala.
The development marks the beginning of the annual retreat of the southwest monsoon, which usually begins from western Rajasthan in September. The withdrawal process is expected to gradually move towards other parts of northwest and central India depending on rainfall and atmospheric conditions, the Met office said.
The south-west monsoon usually begins to withdraw from the north-west in September and its retreat proceeds gradually towards the south and east. Developments will be closely watched as the monsoon accounts for about 70% of India’s annual rainfall and its retreat marks the transition to the post-monsoon period.
Expected precipitation
Meanwhile, the IMD in its latest forecast also said that rainfall is likely to remain active over several parts of the country in the coming week, with widespread showers predicted over parts of east, central and south India.
In eastern India, widespread rainfall is likely over Andaman and Nicobar Islands and Gangetic West Bengal from 21 to 26 September, while Odisha, Jharkhand and sub-Himalayan West Bengal and Sikkim are expected to experience widespread rain from 22 to 26 September. Bihar may experience widespread rainfall during 24-26 September.

In south India, widespread rainfall is forecast over Kerala, coastal Karnataka and parts of Karnataka during the week, while Telangana and coastal Andhra Pradesh are likely to receive rain at different times.

So far, the southwest monsoon season has brought cumulative rainfall of 695.6 mm during June 1 to September 19, which is 15% below the normal of 817.2 mm.
Meanwhile, heavy rainfall lashed several parts of India during the 24 hours that ended at 8:30 am on Sunday, with Telangana, Rayalaseema and Tamil Nadu receiving very heavy rainfall, the IMD said. 12-20 cm of rain was recorded at isolated places in the three regions.
Heavy rainfall of 7-11 cm was also recorded in parts of Odisha, Madhya Pradesh, Andaman and Nicobar Islands, Chhattisgarh, Assam, Nagaland and south interior Karnataka, according to the weather agency. The rainfall comes amid increased monsoon activity over parts of south, east and central India, with the IMD predicting more heavy rains in several regions in the coming days.
