Chennai, April 14 : The India Meteorological Department (IMD) has forecast that intense heat conditions will continue across interior parts of Tamil Nadu over the next few days, with maximum temperatures likely to remain up to 3 degrees Celsius above normal until at least Friday.

The department has warned that hot and dry weather will persist, particularly during peak afternoon hours, increasing the risk of heat-related illnesses and public discomfort across several districts.

According to the IMD, interior regions are expected to record temperatures ranging between 39 and 41 degrees Celsius over the coming days, while coastal areas will experience high humidity along with elevated temperatures.

In Chennai and its suburbs, the maximum temperature is likely to touch 37 degrees, with humid conditions making the weather feel significantly hotter than recorded levels.

On Monday, the heatwave tightened its grip across Tamil Nadu, with temperatures crossing 40 degrees in multiple locations. Karur Paramathi recorded the highest temperature at 40.6 degrees. Vellore and Erode followed closely at 40 degrees each. Madurai Airport, Namakkal, and Tirupattur registered around 38.9 degrees, while Coimbatore, Madurai city, Salem, and Dharmapuri recorded temperatures near 38.3 degrees. Palayamkottai and Tiruchirappalli saw the mercury rise to approximately 37.8 degrees, reflecting the widespread intensity of the heat.

Despite the prevailing heat, the IMD has indicated the possibility of some relief later this week. A low-pressure system extending from northeast Bihar to southern Tamil Nadu is expected to trigger light rainfall in select regions.

Isolated showers are likely over the Western Ghats districts, delta regions, and coastal areas of Ramanathapuram until Sunday, which could bring temporary respite from the heat.

Authorities have advised residents to remain cautious, stay well hydrated, avoid direct exposure to sunlight during peak hours, and ensure proper care for vulnerable groups such as children, the elderly, and those with existing health conditions.

With temperatures continuing to remain above normal, Tamil Nadu is expected to face persistent heat stress conditions in the coming days before any gradual weather transition sets in.
