The three main sub-divisions in Northeast India i.e. Sikkim, Sub-Himalayan West Bengal, Assam, Meghalaya and Arunachal Pradesh have been receiving heavy rainfall activity since last few days, which has led to flood situation in many parts of these areas.
Floods over these areas are mostly because of the heavy rains in Assam and Arunachal Pradesh as the river Brahmaputra and its tributaries pass through both these states. However, these heavy rains can be attributed to the eastern part of the axis of Monsoon trough that lies close to the foothills of the Himalayas.
In the last 24 hours from 08:30 am on Tuesday, Cherrapunji recorded 225 mm of rain, followed by Mangan 80.7 mm, Pasighat 66.3 mm, Itanagar 42.7 mm, Tezpur 39.1 mm, Shillong 34 mm, Dhubri 20.6 mm, Silchar 18.1 mm, Dibrugarh 12.3 mm, Golaghat 6.6 mm.
Now, a cyclonic circulation is seen coming up over North Bay of Bengal which is likely to pull the Monsoon trough southwards. On account of this, temporary reduction in rainfall activity over few pockets will be seen.
However, most parts will continue to receive widespread rains as moist southerly winds are likely to continue and no change in wind pattern is expected.
Therefore, we can say that moderate to heavy rains are likely to continue, no significant reduction in rainfall activity is expected over all the areas.
