This fresh spell of rains can be attributed to the fresh low pressure area that has developed in west-central Bay of Bengal off the Andhra Pradesh coast. The system has been infusing moisture over several parts of North Coastal Tamil Nadu, resulting in light to moderate showers.
According to weathermen, the system will move inland and will continue to drench North Tamil Nadu including Chennai for the next 2-3 days. However, rains will not be heavy and widespread in nature and many places will only get light to moderate showers with one or two good spells.
In wake of this, maximum temperatures have also taken a dip and day maximum is presently settling at 32.1°C, which was two degrees below normal.
So far, Chennai has recorded mere 32.3 mm of rain against its monthly average of 140.4 mm of rain. However, with these rains, we can expect situation to improve up to some extent. At present, the cumulative rainfall deficiency for Tamil Nadu stands at 4%, which is near to normal.
The state including Chennai does not record much rains during the Southwest Monsoon as it falls under a rain shadow region. The state records its majority of rainfall during the Northeast Monsoon that spans from October to December. Chennai also records more than 60% of its rainfall during that period.
