According to Skymet Meteorology Division in India, the average country rainfall in first six days of October was 4.1 mm against the normal of 20.8 mm. While parts of Northeast India, including Assam and Bihar are witnessing a rain deficiency of 99%, Rajasthan in Northwest is seeing a rain deficiency of 86% for the same period.
Northeast Monsoon
Unlike the Southwest Monsoon, Northeast monsoon does not have any specific date. Yet late September to first week of October is the time when Northeast Monsoon generally commences. However, October started on a poor note as the average country rainfall on October 1 was 1.7 mm against the normal of 4.1 mm.
Northeast monsoon also means that South Peninsula witnesses heavy rainfall while North and Northwest India observes only light rain showers. According to Skymet Meteorology Division in India, the spell of least rain during the first week of October is likely to pick up in the beginning of the second week commencing with the weather activity in Bay of Bengal.
Effect of Cyclonic Storm
A low pressure area that has formed over Tenasserim coast area adjoining Andaman Sea is likely to move towards Orissa and Coastal Andhra Pradesh in next 48 hours. However, it is not going to enhance rain activity in South India. Moreover, the rainiest pocket of South Peninsula, Tamil Nadu, will also witness minimal rain activity due to this storm.
