Northeast Monsoon season makes the state of Tamil Nadu a getaway for tourists during the month of October. Even though Northeast Monsoon still hasn’t made its onset over the state, but Tamil Nadu has been receiving good rains since the beginning of October itself.
In fact, similar to Kerala, October is also the rainiest month for Tamil Nadu, as good rains with moderate to heavy intensity are observed especially over the coastal and northern parts. Moreover, as of today, Tamil Nadu is 21% rain surplus and has received 143.1 mm of rains against its normal of 180.2 mm.
Thus, we can say that even before the arrival of Northeast Monsoon, which is expected towards the end of this month, Tamil Nadu has already received more than two third of its normal rains.
Many cities in Tamil Nadu have recorded rains above 200 mm and 300 mm till now, such as Coonoor 387.2 mm, Valparai 283 mm and Ooty 269 mm.
During the last 24 hours also, widespread rains were observed over many parts of Tamil Nadu. In the last 24 hours from 08:30 am on Sunday, Kanyakumari recorded 66 mm of rain, followed by Nagapattinam 33 mm, Thondi 26 mm, Parangipettai and Mailam 23 mm.
Now during the next few days, we expect rains to reduce significantly. However, due to the El Nino conditions building up, we can say that Northeast Monsoon season is going to be good for Tamil Nadu.
Therefore, we can say that, once Northeast Monsoon makes its onset over Tamil Nadu, rains will once again enhance over the state and increase the rain surplus for Tamil Nadu for the month of October.
Rain and thundershower activities are likely over Cuddalore, Dindigul, Karaikal, Madurai, Nagapattinam, Pudukkottai, Ramanathapuram, Sivaganga, Thanjavur, Theni, Thiruvarur, Thoothukkudi, Tiruchirappalli, Tirunelveli and Virudhunagar during the next 3-4 hours.
