The weather system which originally formed as a cyclonic circulation in north Bay of Bengal has been lingering on for quite some time. It intensified into a low pressure system and has been vital in giving Monsoon rain to Northeast India, Sub Himalayan West Bengal, Bihar and Uttar Pradesh. It has already weakened and is now positioned over Bihar and adjoining Sub Himalayan West Bengal as an upper air cyclonic circulation.
After bringing good Monsoon rain over many parts of central and east Uttar Pradesh on Monday, rainfall has reduced over the entire state.
As the system is moving away from Uttar Pradesh, rain has reduced in Bahraich and Fursatganj, where 315 mm and 358 mm of rain respectively had been observed on Sunday. Rain has reduced in Bihar as well with Patna receiving only 0.6 mm of rain. According to the latest weather update by Skymet Meteorology Division in India, the system is moving along the foothills in a west to east direction. It will continue to move slowly and give intense weather activity over Sub Himalayan West Bengal and Northeast India, particularly Arunachal Pradesh and Assam for the next 48 hours.
The system has been bringing good Monsoon rain over East India and played a crucial role in mitigating the rain deficiency in other parts of the country.
