Tamil Nadu received heavy to very heavy rainfall activity during the last few days. These rains were attributed to the low-pressure area over Southeast Arabian Sea which gradually intensified into a cyclone. Moreover, a cyclonic circulation was also persisting over Southwest Bay of Bengal near South Tamil Nadu and Sri Lanka Coast.
Tamil Nadu received the highest amount of rain during the first week of October. In fact, as of October 7, the state of Tamil Nadu is largely rain surplus by 133%.
Meanwhile, during the last 24 hours, the southern and interior districts of Tamil Nadu received moderate rains. Meanwhile, light rains occurred over the northern parts.
In the last 24 hours from 08:30 am on Sunday, Nagapattinam recorded 25 mm of rain, followed by Madurai 21.2 mm, Adiramapatnam 21 mm, Kanyakumari 15.6 mm, Pamban 14.3 mm, Valparai 7.6 mm and Kodaikanal 5.3 mm.
Now, the cyclone has moved away in a northwest direction. Therefore, we expect rains to reduce significantly over Tamil Nadu. However, light to moderate rains will continue over the state for another 24 hours.
The conditions have also become favorable for Northeast Monsoon to set in. Thus, we do not expect weather to go completely dry and on and off light rains are expected to continue during the next few days.
Rains may once again increase around October 15 and 16 over the entire state of Tamil Nadu. So, we can say that the month of October is turning out to be a good one for the southern state in terms of rain.
