The southwest monsoon might finally start withdrawing from parts of North-West India over the next three days, signaling the end of its four-month journey over the country that started in June, the India Meteorological Department (IMD) said. However, though the retreat might begin from next week, the rains might not descend quickly, as the met department predicted fresh spells of rains in Vidarbha, Chhattisgarh and east MP on September 21-22 and over Odisha, Coastal areas north Andhra Pradesh and Gangetic West Bengal on September 19-21.

"Hence conditions are becoming favourable for the withdrawal of Southwest Monsoon from parts of northwest India during next three days," the IMD said.
