The formation of the Confluence zone along with the presence of the upper level Trough had resulted in light to moderate rain and thundershower at many places over interior and northern parts of Tamil Nadu in the last two days. In fact, many parts of Chennai have been experiencing light rain and drizzle since last two to three days. However, these rains were highly localised and remained confined only to small areas of Chennai.
Now, the confluence zone is on the verge of weakening due to which we expect rains to make an exit from the parts of Tamil Nadu including the city of Chennai. Already, a change has been noticed and intensity of rain has been reduced to a large extent since the last 24 hours.
Moreover, these rains have dropped the temperatures by 2℃ to 3℃ thereby leading to the comfortable evening and nights for the residents.
Now, as the Confluence zone completely weakens, weather will go completely dry over the entire region. However, some systems may develop in the near future which might give another spell of light rain over the state of Tamil Nadu around February 4 and 5, but chances of heavy rains are completely ruled out during that time for the region.
