IMD predicts rain, thunderstorms in South Tamil Nadu

The India Meteorological Department (IMD) has forecast moderate rainfall accompanied by thunderstorms in parts of southern Tamil Nadu and along the Western Ghats on Monday, offering limited relief amid rising temperatures across the region.According to the Regional Meteorological Centre, a low-pressure system prevailing over the Gulf of Mannar and adjoining south-central Maharashtra is influencing weather patterns across southern India.Under its impact, several districts in south Tamil Nadu and areas along the Western Ghats are expected to receive moderate rainfall with occasional lightning.

The weather system is likely to persist over the next few days, with the IMD predicting continued rainfall activity in key districts. Coimbatore and Nilgiris, in particular, are expected to witness moderate showers on Tuesday and Wednesday.The forecast further indicates that rainfall will continue in these regions towards the end of the week, with similar conditions likely on Friday and Saturday.
Meanwhile, Chennai is expected to see partly cloudy skies over the next two days. No significant rainfall activity has been forecast for the city during this period, although cloud cover may offer mild respite from the prevailing heat.Despite the expected rainfall in certain regions, temperatures across Tamil Nadu, Puducherry, and Karaikal are likely to remain above normal.The IMD has predicted that maximum temperatures may rise by 2 to 3 degrees Celsius above the seasonal average between March 23 and March 26, leading to warm and humid conditions in several areas.Weather officials have advised residents, particularly in rain-prone districts, to remain cautious during thunderstorms and lightning activity. At the same time, people have been urged to take necessary precautions against heat-related discomfort, especially in regions where temperatures continue to remain elevated.The evolving weather pattern highlights a mix of summer heat and localised rainfall across Tamil Nadu, driven by atmospheric instability linked to the prevailing low-pressure system.
