Huge monsoon rain deficit for Chennai this year
Posted on: 18/Dec/2018 12:53:58 PM
With the nearing end of north east monsoon Chennai is standing in a delicate position of 54% rain deficit for this year that will surely affect the bio diversity and growing water needs. Starting from the month of October Chennai has received only 343.4mm rain. The expected amount of rain for this year was 747.1mm as per the earlier reports.
Though the reports of huge rain deficit for the year the meteorological department has mentioned a possibility of rain for next three days after a complete dry spell. The Weather forecast of the department has shown the energy left over the ocean formed as the result of Phethai, a cyclone with low atmospheric pressure in an elongated region. The system is not that strong to give expected amount of rain to northern regions of Tamil Nadu. There is no low pressure or depression inside the ocean but there are clear signs of sustained rainfall to hit the city.
Temperature over the Bay of Bengal is higher leading to the process of convection. This will affect the monsoon rains hitting the coast on a full swing. So the expected rains will not have a big impact on the deficit said the sources of the weather department. IMD deputy director, S. Balachandran informed about the expected rainfall at the end of this week having a blurred side without any concrete rain readings.
Outer band of Phethai cyclone was only 40 kms from Chennai and so there were less hopes for a heavy rainfall. The system moved northwards to the Andhra coast and will not impact the coastal regions of north Tamil Nadu with heavy rains.
