After 2010, TN gets excess rainfall due to South West monsoon

Meteorological department officials said that there will be scattered rainfall on Monday in Tamil Nadu and Puducherry, due to a shear zone formation over north Tamil Nadu and Kerala.

The maximum temperature will be 32 degrees Celsius and the minimum temperature will be 26 degrees Celsius.

Srikanth K, weather blogger at Chennaiyil Oru Mazhaikalam (COMK), said that over the next few weeks, the wind patterns will change towards the easterly, as the southwest monsoon starts withdrawing.

“When the winds change daily, there will be thunderstorms in the interior areas of the state.

Winds will change in different areas in different pockets. It is these areas that will get good rainfall,” he said.

The Southwest monsoon, which begins from June 1 and remains active till September 30, has been beneficial for Tamil Nadu and Puducherry, pointed out the weather blogger.

“The state has received 27 % excess of rainfall from the southwest monsoon from June 1 till September 24. This is the best amount of rain the state has received so far due to the Southwest monsoon,” added Srikanth.

Blogger at the Kea weather portal, Bhaskaran Shivaraman, said that with the state already experiencing excess rainfall due to the Southwest monsoon, there will also be good rain during the Northwest monsoon. “Withdrawal of Southwest monsoon happens in the third week of September gradually. Now, in most of the states in north India, rains have receded. Only the Western Ghats – parts of Kerala and Karnataka – are getting rains.

After this, we expect the Northeast monsoon to set in by third week of October, which will bring a good amount of rain to the state,” he added.

Rain will occur in the next two days due to upper air circulation, said Bhaskaran, adding that most of the dams have been benefited due to rain from the Southwest monsoon.

“Most dams in Tirunelveli and Coimbatore have reached the brim. Mettur, on Saturday, touched 80 feet. Parts of Tamil Nadu, like Tirupur and Erode and most of the Western Ghats have also received good rainfall,” he noted.
