Weather department issues orange alert for TN's Ghat districts
The Regional Meteorological Centre (RMC) in Chennai has issued an orange alert for the Ghat areas of Coimbatore and the Nilgiris between June 13 and 15, forecasting heavy rainfall of up to 20.4 cm during the period. The alert comes as Tamil Nadu begins to witness the revival of the southwest monsoon after a prolonged spell of intense summer heat. An orange alert is issued when heavy rainfall is anticipated, typically exceeding 115.6 mm and up to 204.4 mm within 24 hours, and indicates a heightened risk of flooding. After days of soaring temperatures, parts of the north interior Tamil Nadu and Chennai have received welcome relief with sudden afternoon showers. Localities such as Mylapore, Chintadripet, Anna Nagar, Adyar, and Chepauk experienced sharp rainfall from around 2.30 p.m. on Monday, leading to a dramatic drop in temperature. The day's maximum fell from 38 degrees Celsius to 30 degrees by 4.00 p.m., aided by overcast skies and cool winds. However, the rain also caused brief traffic disruptions, with waterlogging reported along arterial stretches, including Jawaharlal Nehru Salai. Weather stations at Nungambakkam and Puzhal recorded 2 cm of rainfall by 5.30 p.m. on Monday. The RMC has forecast continued wet weather across Tamil Nadu and Puducherry for the rest of the week. Thunderstorms accompanied by gusty winds reaching speeds of 30-40 kmph are expected in isolated pockets. On Tuesday, isolated heavy rainfall is likely in seven districts, including Erode, Vellore, and Ranipet. The intensity of rain is projected to increase from Wednesday, with 15 districts -- including the delta region, interior Tamil Nadu, and the Western Ghats -- likely to experience heavier downpours. B. Amudha, Head (Additional In-charge) of RMC Chennai, attributed the current weather pattern to the formation of an east-west trough in the upper atmosphere. She said the trough is facilitating the monsoonal flow and that rainfall would likely intensify in northern districts first before shifting towards the Ghat regions. The prevailing weather system is expected to lower daytime temperatures by around 2 degrees across several parts of the state. The official also confirmed that the southwest monsoon is gradually reviving over Tamil Nadu, in line with similar activity recently seen in Karnataka. Chennai and its suburbs can expect light to moderate showers to continue through Tuesday, providing ongoing relief from the oppressive summer heat.

TN sees fewer heatwave days, higher rainfall this summer: Regional MeT Centre
Chennai: Tamil Nadu is witnessing a notably different summer this year, with fewer heatwave days and significantly higher rainfall compared to the usual seasonal trends, according to the Regional Meteorological Centre (RMC) in Chennai. B. Amudha, Head of RMC Chennai, stated that the number of heatwave days -- defined as days when temperatures exceed 41 degrees Celsius -- has declined across the state compared to the past five years. At the same time, the state has received far more rainfall than usual during the ongoing monsoon season. As per RMC data, Vellore reported the highest number of heatwave days this summer, with temperatures exceeding 40 degrees Celsius on 16 days. Karur Paramathi followed closely, recording high temperatures on 10 days. Erode registered the highest temperature of the season -- 41.2 degrees Celsius -- on May 15. In contrast, other districts such as Vellore and Madurai recorded maximum temperatures of 40 degrees only on one or two days. In Chennai, the mercury touched 40 degrees just once throughout the summer. However, rainfall in Chennai has been remarkably high. The city received 129 per cent more rainfall than the average, recording 12 cm of rain this summer. Across Tamil Nadu, the state recorded 25 cm of rainfall against the normal 13 cm -- an increase of 97 per cent compared to seasonal norms. Amudha added that the long-period average (LPA) -- a climatological benchmark measuring average rainfall over a specific time period -- is also expected to rise this year. The LPA for Tamil Nadu may reach up to 110 per cent, while the national average is expected to be around 106 per cent, according to the forecast by the India Meteorological Department (IMD). Despite the promising rainfall trend, the RMC has cautioned that some northern interior districts may experience a dip in rainfall during June. In other regions, rainfall is expected to be normal or above normal. Chennai, meanwhile, can expect light to moderate showers over the next few days, added Amudha. The shift in weather patterns highlights the dynamic nature of climate conditions and the importance of continuous monitoring and forecasting to ensure preparedness and resource management across the state.

Weather dept predicts heavy rainfall in TN from tomorrow
Chennai: The Regional Meteorological Centre (RMC) in Chennai has forecast an increase in rainfall activity across Tamil Nadu starting May 14, with heavy showers expected to lash districts along the Western Ghats and interior regions for three consecutive days. Until then, however, parts of Tamil Nadu and Puducherry will continue to endure intense heat. Daytime temperatures are expected to hover two to three degrees Celsius above normal, particularly in pockets such as Chennai, where high humidity may add to discomfort. A marginal dip in temperature is anticipated from Wednesday onwards. On Monday, Madurai airport recorded the highest maximum temperature in the State at 41 degrees Celsius. Erode and Karur Paramathi also crossed the 40 degrees C mark, reflecting the prevailing heatwave conditions across several districts. The RMC attributed the upcoming rainfall to pre-monsoon developments in both the Arabian Sea and the Bay of Bengal. B. Amudha, Head (Additional In-Charge) of RMC Chennai, said cloud formation is likely to intensify over the south Arabian Sea, Maldives, Comorin area, south Bay of Bengal, and Andaman and Nicobar Islands -- potentially triggering rainfall over parts of Tamil Nadu and Kerala. Dynamic weather models indicate that districts along the Western Ghats -- including Nilgiris, Coimbatore, Tiruppur, Dindigul, Erode, Dharmapuri, Krishnagiri, Tirupattur, Salem, and Tiruvannamalai -- are likely to receive heavy rainfall on May 14. Showers may continue in isolated areas, especially in Tirupattur and Krishnagiri, through Thursday and Friday. The RMC has predicted scattered rainfall across the State till May 18, with occasional thunderstorms and gusty winds reaching speeds of 40-50 kmph in some regions. The approaching Southwest Monsoon, expected to hit Kerala around May 27, could further enhance rainfall activity in Tamil Nadu. Both clouding branches -- over the Arabian Sea and the Bay of Bengal -- will be closely monitored for signs of monsoon progression, Amudha added.
