Chennai, April 2 (IANS) The Regional Meteorological Department has forecast light to moderate rainfall in parts of southern Tamil Nadu over the next few days, even as temperatures are expected to gradually increase across the state.

According to an official statement, a trough of low pressure extending from the interior regions of Tamil Nadu to the northern interior parts of Karnataka at an altitude of around 900 metres is influencing the current weather pattern. This atmospheric condition is likely to trigger scattered rainfall activity, particularly in the coastal districts of South Tamil Nadu and along the Western Ghats.

On Thursday, light rain is expected at one or two places in these regions. The rainfall activity is likely to intensify slightly on April 3 and 4, with the weather department predicting light to moderate rain accompanied by thunderstorms at isolated locations across the south coastal districts and Western Ghats areas.

However, the rest of Tamil Nadu, along with Puducherry and Karaikal, is expected to largely remain dry during this period, with no significant rainfall activity forecast outside the identified regions.

While rainfall may bring temporary relief in certain areas, the Meteorological Department has also cautioned that maximum temperatures are likely to rise across Tamil Nadu and Puducherry over the coming days.

The increase in daytime temperatures could lead to warmer and more humid conditions, particularly in inland districts.

In Chennai, the weather is expected to remain partly cloudy for the next two days. Despite the cloud cover, daytime temperatures are likely to remain high, with the mercury expected to exceed 35 degrees Celsius.

The combination of heat and humidity may result in uncomfortable conditions for residents. Meteorologists have advised people, especially those in heat-prone areas, to take necessary precautions, including staying hydrated and avoiding prolonged exposure to direct sunlight during peak afternoon hours.

The evolving weather pattern reflects a transitional phase, where localised rainfall in southern and hilly regions coincides with a broader warming trend across the state, marking the gradual onset of summer conditions in Tamil Nadu.
