A well-marked low-pressure area is over Jharkhand and adjoining Gangetic West Bengal. Its impact has been felt over many parts of Gangetic West Bengal during the last 24 to 48 hours. Moderate to heavy showers occurred over Gangetic West Bengal, parts of Odisha and Jharkhand. This system is expected to move in the west-northwest direction. Rain activities will be intense over Sub-Himalayan West Bengal and Bihar as well as over Sikkim and western parts of Assam.
Withdrawal of monsoon has come in Northwest and parts of Central India. Westerly winds are blowing over the Northwest and Central parts of the country. These westerly winds will not allow the well-marked low-pressure area to move further West. Therefore, it may weaken into a low-pressure area and will continue to hover over Bihar and its adjoining areas for at least 2 to 3 days. Rain activities will also remain concentrated over eastern parts of the country, particularly over Bihar, Jharkhand and West Bengal.
Southwest monsoon was not very generous for eastern parts of the country as most of the Meteorological divisions of East India remained drain deficient during monsoon season. Therefore, we can say that the next 4 to 5 days will be rainy for the eastern parts of the country.
