The Northeast Monsoon 2018 is almost about to end and the seasonal rainfall deficiency for the country is standing at 43% as on December 25. The only exception for now is Andaman and Nicobar Islands which is excess by 27%, whereas, other states are either normal or rain deficit.
The Long Period Average (LPA) is -/+ 19% and as per the records Puducherry, Kerala and Lakshadweep all are in normal range category, however on the lower side of normal.
As on December 25, state of Karnataka, Andhra Pradesh, Telangana and Tamil Nadu are rain deficit by 47%, 57%, 65% and 22%, respectively.
In this year, only three significant weather systems developed over Bay of Bengal- Cyclone Gaja, Cyclone Phethai and a well-marked low-pressure area. As per Skymet Weather’s Chief Meteorologist, Mr. Mahesh Palawat, the easterly waves which usually gives good rains over the states of Andhra Pradesh and Tamil Nadu remained inactive throughout the season. However, there were small surges in easterly waves which gave scattered rains only.
In the coming days as well, rain activities are not expected to increase. Although, there can be scattered light rains over parts of Andhra Pradesh, Tamil Nadu, Kerala and South Interior Karnataka between December 28-30. Since, the intensity of these rains will be light to very light, hence we do not expect any improvement in the rainfall deficiency. Thus, Northeast Monsoon 2018 is going to end on a deficit note.
Many parts of the region will remain rain deficient and many districts would continue to face drought like conditions. Also, the failure of Northeast Monsoon will have repercussions on the upcoming Rabi crops because of the depletion of soil moisture.
