Monsoon has returned from most parts of North West India. Conditions are becoming favorable for further withdrawal from some more parts of Gujarat, Chhattisgarh. Conditions are becoming favorable for withdrawal of monsoon over Gujarat, Chhattisgarh, Madhya Pradesh, Jharkhand, most parts of Bihar, Maharashtra, Odisha and West Bengal. India Meteorological Department (IMD) gave this information.
Monsoon started its withdrawal on 6 October as compared to the normal date of 17 September, but in the last four days it has withdrawn from almost half of the country including Punjab, Haryana, Delhi and parts of Gujarat, Bihar and Madhya Pradesh. Even in years when the onset of monsoon is slow, the withdrawal of monsoon can be quick. This is because there is no low pressure system that can bring further rain.
Only low pressure system can delay monsoon – DS Pai
The India Meteorological Department (IMD) said that there is no other system bringing rain after the passage of Cyclone Gulab and the associated low pressure system. However, it is expected that a low pressure area will form North Andaman Sea which is likely to cross Odisha coast. This system may slightly delay the complete withdrawal of monsoon and bring rain to Maharashtra. DS Pai, Scientist and Head of Climate Research and Services, IMD, Pune gave this information.
This time the return of monsoon is fast – Mahesh Palawat
Mahesh Palawat, Vice President, Skymet Weather, said that the withdrawal of monsoon is very fast this time. It is expected that Monsoon will withdraw from most parts of the country during the next 3 to 4 days, but there is a slight chance that the low pressure area over Andaman Sea may turn into a cyclone or depression, which is very May bring more rain. There is no warning of cyclogenesis from IMD so far.
Cyclone Circulation over North Andaman Sea – IMD
According to IMD, a Cyclone Circulation is persisting over North Andaman Sea. Under its influence, a low pressure area is likely to form in this area during the next 36 hours. It is very likely to become more marked and move west-northwestwards towards South Odisha-North Andhra Pradesh coasts during subsequent 4-5 days. Under its influence, light to moderate rain at most places with isolated thunderstorms (wind speed reaching 40-50 kmph gusting to 60 kmph) and heavy rain is likely over Andaman and Nicobar Islands during next 5 days. Chances are.
