Chennai, April 1 (NationPress) Following a period of extreme summer temperatures, Tamil Nadu is poised to experience a welcome change with light to moderate showers anticipated across the state from April 2 to 4, as reported by the Regional Meteorological Centre (RMC).
This shift in weather is linked to various meteorological factors, chiefly a cyclonic circulation over the southwestern Bay of Bengal and a wind discontinuity affecting peninsular India. These weather systems are expected to trigger rain and thunderstorms in Tamil Nadu, Puducherry, and Karaikal.
Over the last week, temperatures have surged throughout the region, with Vellore and Madurai reaching a sweltering 40 degrees Celsius — the highest recorded in the state this year. Nevertheless, meteorologists forecast a reduction of 2 to 3 degrees in maximum temperatures as rainfall activity increases.
The interior and western regions of Tamil Nadu are likely to benefit the most from these expected showers. Districts such as Coimbatore, Tenkasi, Virudhunagar, Theni, and Dindigul are anticipated to receive rain on April 2.
On April 3, isolated showers are forecasted for the mountainous areas of Coimbatore, the Nilgiris, and Erode. Light to moderate rainfall may persist in isolated regions of the state on April 4 and 5, according to the latest weather updates from the RMC.
A trough extending from interior Odisha to the Comorin region — traversing through South Chhattisgarh, interior Maharashtra, Karnataka, and Northern Tamil Nadu — is also expected to aid in this weather transformation.
Although maximum temperatures may remain 2 to 3 degrees above the norm, from April 2 onwards, temperatures are projected to revert to normal or even dip slightly below average across the state.
On Monday, Salem recorded the highest temperature at 39 degrees Celsius. Weather stations in Dharmapuri, Erode, Karur Paramathi, Madurai Airport, and Vellore all reported temperatures exceeding 38 degrees. Conversely, Chennai’s Nungambakkam observed a relatively cooler 33.7 degrees. The city is not expected to experience rain over the next 48 hours, although maximum temperatures could reach 35-36 degrees.
Despite the recent heat wave, Tamil Nadu had a robust northeast monsoon season, recording 14 percent more rainfall than average. The state received 447 mm of rain, surpassing the seasonal norm of 393 mm. Chennai alone experienced a 16 percent increase in rainfall, totaling 845 mm, while Coimbatore noted a significant 47 percent rise above average. These occurrences followed the devastating Cyclone Fengal, which struck Tamil Nadu and Puducherry from November 29 to December 1 last year. This cyclone caused heavy rains and was succeeded by additional showers from a low-pressure system in the southern Bay of Bengal. The disaster resulted in 12 fatalities, submerged 2.11 lakh hectares of agricultural and horticultural land, and affected 69 lakh families and 1.5 crore individuals.
