During the months of January and February, there have been a few spells of unseasonal rain over central and eastern parts of the country. Parts of Bihar have witnessed hailstorm activities during the first week of this month leading to widespread damage to crops.
Another spell of rain is possible over parts of East Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, North Odisha and West Bengal between February 9 and 10. Two successive Western Disturbances are expected to approach the Western Himalayas, with one reaching on February 6th and another on February 8 or 9.
Along with this, a Cyclonic Circulation may form over Northeast Madhya Pradesh and adjoining area on February 9 and a trough is expected to extend from West Bengal to south Odisha coast on February 10. Humid winds from Bay of Bengal are also expected to feed moisture over East India.
These rains will be passing showers and we do not expect moderate to heavy showers which cause damage to the crops. The months of January and February are considered as the least rainy for east and Central India. However, exceptions are always there, and we can say that the year 2022 is an exception for East and Central India in terms of unseasonal rains.
