Chennai: The Regional Meteorological Centre in Chennai has issued a weather advisory indicating a likely rise in maximum temperatures across Tamil Nadu, even as the southwest monsoon continues to influence sporadic rainfall in the region. According to the forecast, temperatures in some areas are expected to be 2 to 3 degrees Celsius above normal from today until August 29th. This comes amidst the development of a low-pressure system over the northwest Bay of Bengal, which is expected to intensify weather patterns in the coming days.
The meteorological department’s statement predicts a consistent pattern of light to moderate rain with thunder and lightning at isolated places across Tamil Nadu, Puducherry, and Karaikal for this week. A significant feature of the forecast is the prediction of strong surface winds, gusting between 30 to 40 kmph, from August 26th to 28th. The western hilly regions, particularly the Nilgiris and Coimbatore districts, are likely to experience heavier rainfall during this period, potentially leading to localized downpours. For Chennai and its suburbs, a partly cloudy sky with chances of light rain in a few areas is expected. The city is set to experience a noticeable temperature increase, with maximums reaching 36° Celsius by tomorrow.
Detailed Day-by-Day Outlook and Temperature Advisory
The weather agency provided a specific day-wise breakdown, indicating that while rainfall will be widespread, it will generally be isolated and light to moderate in intensity. The forecast for heavy rain is currently confined to the hilly terrains of the Nilgiris and Coimbatore on August 27th and 28th. The key takeaway for the public is the combination of heightened humidity due to impending rains coupled with above-normal daytime heat.
Maximum temperatures are projected to hover between 35-36°C in Chennai, with similar increases expected in other parts of the state. Residents are advised to stay hydrated, plan outdoor activities accordingly.
