Chennai: The Northeast Monsoon has intensified over Tamil Nadu, with the India Meteorological Department (IMD) issuing a detailed multi-day forecast predicting heavy to very heavy rainfall across multiple districts, including Chennai. The weather agency has also indicated that a new low-pressure area is expected to form over the southeast Bay of Bengal around November 22, which is likely to strengthen and amplify the rainfall activity.
Tamil Nadu Weather Forecast: District-Wise Alert & Heavy Rains Target Coastal and Southern RegionsThe IMD has provided a day-by-day breakdown of the weather alert, highlighting districts that are likely to experience heavy downpours:
Today & Tomorrow (Nov 19-20): Mayiladuthurai and Cuddalore districts are on alert for heavy rains. Widespread light to moderate rain with thunderstorms is expected across Tamil Nadu, Puducherry, and Karaikal.
November 21: The heavy rain alert expands to include several southern and coastal districts, including Kanyakumari, Tirunelveli, Thoothukudi, Ramanathapuram, Nagapattinam, Mayiladuthurai, and Cuddalore.
November 23-24: The rainfall intensity is expected to peak, with a widespread heavy rain alert covering a vast swathe of the state. Northern coastal districts, including Chennai, Tiruvallur, Kanchipuram, and Chengalpattu, are added to the list, along with numerous other districts from the Cauvery Delta and southern regions.
For the state capital, the sky is expected to be partly cloudy with a likelihood of light to moderate rain accompanied by thunder and lightning in a few areas. The maximum and minimum temperatures are likely to hover around 31-32°C and 25-26°C respectively. While the immediate forecast for Chennai points to moderate rainfall, residents are advised to stay updated as the situation could change with the development of the new weather system later this week.
Key Factor: New Low-Pressure System to Form on November 22A significant factor in the forecast is the development of a low-pressure area over the southeast Bay of Bengal around November 22. The IMD has stated that this system is likely to intensify further. The movement and strength of this system will be crucial in determining the exact distribution and intensity of rainfall over Tamil Nadu and adjoining areas in the latter half of the week, potentially leading to more widespread and intense downpours.
