The India Meteorological Department’s Regional Meteorological Centre in Chennai has issued a detailed seven-day weather forecast highlighting spells of moderate to heavy rainfall across parts of Tamil Nadu, with a specific warning for interior districts later in the week.
According to the forecast, the initial days are expected to witness light to moderate rainfall at isolated locations over the Western Ghats districts and south coastal Tamil Nadu, with weather activity set to intensify from April 30 onward. The bulletin states that “moderate to heavy rain is likely to occur at isolated places over districts including Coimbatore, Nilgiris, Erode, Salem, Dharmapuri and Krishnagiri” on April 30.
The heavy rainfall warning continues into May 1 and May 2, with similar conditions expected to persist over interior regions such as Coimbatore, Nilgiris, Erode, Salem, Dharmapuri, Vellore, Tirupattur and Krishnagiri districts.
For the remaining parts of Tamil Nadu, including Puducherry and Karaikal, the forecast indicates light to moderate rainfall at a few locations, along with thunderstorms and gusty winds in isolated pockets. However, the overall trend suggests that the heaviest precipitation will remain concentrated over the western and interior parts of the state.
In contrast, coastal regions are expected to experience predominantly hot and humid conditions during the early part of the forecast period. The meteorological department stated that “hot and humid weather is likely to prevail over coastal areas of Tamil Nadu, Puducherry and Karaikal,” with maximum temperatures expected to remain 2–3°C above normal in some interior pockets.
For Chennai, the local forecast indicates partly cloudy skies, with maximum temperatures ranging between 36°C and 38°C and minimum temperatures around 27°C to 28°C over the next two days. The city is expected to continue experiencing hot and humid conditions, with no significant rainfall during this period.
