The first three months of the Monsoon season were cumulative deficient by 6% for Pan India. Thereafter, September also commenced on dwindled note, in spite of the deep depression passing across the central parts of country.
However, the first 10 days of September did not receive much rain, as only on two occasions good rainfall activity was observed rest on all days Monsoon remained weak and increased the rain deficiency to 7%. In fact, during the last two days, Monsoon remained subdued over almost all parts of the country, except the northeastern states along with Sikkim and Sub-Himalayan West Bengal and the last two days were rain deficient by 54% and 43% respectively.
The remnants of the depression that gave rains over North Madhya Pradesh and Rajasthan have also defused and at present a feeble cyclonic circulation is seen over Haryana and North Rajasthan. With this, the Monsoon trough is likely to shift north of its position all along from western end to the eastern end. It will lie along the foothills.
This situation is expected to increase rainfall activity over the northeastern states of Sikkim, Arunachal Pradesh and Upper Assam along with few eastern states such as Bihar and adjoining Sub-Himalayan West Bengal. We expect heavy to very heavy rains to occur over all these places during the next three days. Flood like situation may also occur over the northeastern states due to the mighty river Brahmaputra and as Bihar and adjacent East Uttar Pradesh lie along the foothills, flooding conditions are likely to make an appearance over these states.
On the other hand, rest of the country i.e. western, central and southern parts barring Interior Karnataka and Interior Tamil Nadu will go almost dry. Monsoon is expected to go weak, as rains will slow down over the entire country. Due to limited Monsoon activities, the Pan India rain deficiency is also expected to increase.
