CHENNAI: May is usually a dry period in Tamil Nadu with soaring temperatures. However, several districts received heavy to moderate rains in the last two weeks. And it is expected to continue for the next five days.

The weather experts said the southwest monsoon will start next week, so the temperature will gradually surge.

From May 1 to 13, the State recorded 10.97 cm of rainfall against the normal rainfall of 8.91 cm, of which Kanniyakumari received 22.37 cm, followed by 21.33 cm in The Nilgiris, 19.2 cm in Theni, while Chennai recorded 2.75 cm of rainfall.

In the last 10 years, Chennai recorded the highest rainfall in May 2016 with 9 cm in 24 hours, due to cyclonic storm Roanu, which came very close to Tamil Nadu. That month, city recorded a total rainfall of 20 cm.

According to RMC, May 2021 received 1.68 cm of rainfall, 1.35 cm in 2014, and at least three years – 2018, 2019 and 2020 did not receive rainfall in May month.

“Formation of atmospheric circulation and low-pressure area is random near Tamil Nadu during May. Almost five years after, cyclonic storm Asani, formed over west central and adjoining southwest Bay of Bengal, brought in heavy rains for several districts on May 10,” said a senior RMC official.

As the State witnessed heavy to moderate rains in the last few days, the maximum temperature reduced drastically in districts which had reported above 100 degrees Fahrenheit.

With the change in wind pattern from next week, the mercury will surge again.

“The southwest monsoon onset in the Andaman Sea is expected in the next two days. And depression formation will occur near neighbouring Kerala next week. So, the wind pattern will change to Tamil Nadu, and rains will decrease, and maximum temperature will surge,” said Srikanth K, a weather blogger.
