Wednesday, May 18: Last week, the remnants of Cyclone Asani brought rainfall to Tamil Nadu, bringing down the state’s otherwise soaring temperatures. And now, after a brief spell of punishing heat, the rain gods are favouring Tamil Nadu once again, at least until May 22.

According to the India Meteorological Department (IMD), a cyclonic circulation over Kerala and a north-south trough running from Maharashtra’s Vidarbha to north Kerala are set to collectively cause bountiful rains across South Peninsular India.

For the next five days, Tamil Nadu will witness widespread light or moderate showers accompanied by thunderstorms, lightning, and gusty winds.

Furthermore, heavy to very heavy rains are likely to lash isolated locations across the southern state on Wednesday and Thursday, followed by isolated heavy rains on Friday and Saturday.

Accordingly, the IMD has issued an orange alert over Tamil Nadu for Wednesday, May 18, so as to urge locals to “be prepared” for the inclement weather. A yellow watch (“be aware” of weather situation) will remain in place over the state until Sunday, May 22. Fishermen have been cautioned against venturing into the sea until May 21.

As per the Regional Meteorological Centre in Chennai, isolated heavy rains are likely in Coimbatore, Tiruppur, Dindigul, Theni, Erode, Salem, Namakkal, Karur, Tiruchirapalli, Dharmapuri, Krishnagiri, Vellore, Tirupattur, Tiruvannamalai and Kallakurichi districts of Tamil Nadu on Wednesday, May 18.

Similar weather is forecast over a few places of north interior Tamil Nadu, Kanyakumari, Tirunelveli, Thenkasi, Theni, Dindigul, Cuddalore, Pudukottai, Delta districts of Tamilnadu and Karaikal area for Thursday, April 19.

In view of the isolated heavy rains forecast, a yellow watch has been placed over Vellore, Tirupattur, Tiruvannamalai and Kallakurichi, Trichy, Namakkal, Karur, Salem, Dharmapuri, Krishnagiri, Erode, Nilgiris, Coimbatore, Tiruppur, Theni and Dindigul for Wednesday.

Chennai will experience generally cloudy skies and light to moderate rainfall through this week. The wet weather will keep the capital city’s daytime temperatures around 35-36 ̊C for the next 2-3 days, but the mercury will return to the 37 ̊C normal thereafter.

Meanwhile, since the beginning of the pre-monsoon season, almost all the southern states have recorded above-average precipitation, and it seems like the ongoing rain spell will contribute more to the stats.

Between March 1 to May 17, Tamil Nadu has registered ‘excess’ rains worth 136 mm, which is 37% higher than its average for this period (99 mm).
