The rain activities have reduced significantly over the entire Tamil Nadu state and during the last 24 hours, no significant rains have been witnessed. However, light to very light rains has been seen over many parts of Tamil Nadu including Chennai. In the last 24 hours, Pamban recorded 5.2 mm of rain, and Coimbatore 0.2 mm.
The reason for these reduced rain activities can be attributed to the reversal of winds due to two major weather systems over the Arabian Sea and the Bay of Bengal.
TheCyclone Kyarrover the east-central Arabian Sea is enhancing the south-westerly winds over Kerala but almost dry westerly winds are prevailing over Tamil Nadu. As per our experts, no significant increase in rainfall activity is expected over the state for at least the next two days.
Therains are likely to increase marginally on October 27. On October 28 and 29, there can be moderate rains with one or two heavy spells over the coastal stations of Tamil Nadu including Chennai. These activities will be in wake of a Cyclonic Circulation over Southwest and Southcentral Bay of Bengal. A trough from this system will extend up to the South Coast of Tamil Nadu.
We can say that after a lull of two-three days, rains will once again pick up the pace. Around October 28 and 29, the rain activities will be subdued over the interior region.
At present Tamil Nadu is the only state which is in normal rain category with a surplus of eleven percent whereas all other southern states are either excess or large excess.
