Chennai is set for a cloudy, rain-dominated week, with intermittent light showers expected on most days, according to the India Meteorological Department (IMD). While the overall pattern remains stable, the IMD has flagged two days with stronger weather alerts.
Chennai Records Warmer Nights
The city has been witnessing slightly higher minimum temperatures, rising between 1.6°C and 3°C above normal. Similar night-time warming was reported across districts including Coimbatore, Dharmapuri, Salem, Tirupattur and Tiruvallur.
Erode and Madurai airports recorded the highest daytime temperature in Tamil Nadu at 32°C, while Karur Paramathi saw the lowest minimum temperature in the plains at 20°C.
Puducherry, Karaikal Shut Schools and Colleges After Heavy Rain
Continuous rainfall since Saturday led to widespread waterlogging in Puducherry and Karaikal,
disrupting daily life and prompting authorities to declare a holiday for all schools and colleges on Monday. Home and Education Minister A. Namassivayam announced the closure of government and private institutions due to the persistent downpour, PTI reported.
IMD Issues Heavy Rain Warning for Tamil Nadu
The IMD said the southern and delta districts of Tamil Nadu are likely to experience intense rainfall. Heavy rain may occur at isolated places in:
Kanyakumari, Tirunelveli, Tenkasi, Thoothukudi, Ramanathapuram, Virudhunagar, Pudukkottai, Thanjavur, Tiruvarur, Nagapattinam, Mayiladuthurai, and the Karaikal region.
What’s Driving Tamil Nadu’s Wet Weather
Multiple developing weather systems in the Bay of Bengal and surrounding seas are influencing the state’s rain pattern:
- A low-pressure area near the South Andaman Sea has strengthened and may intensify into a depression by Monday, with the potential to become a cyclonic storm. Its west-northwest movement is channeling moisture into Tamil Nadu, triggering clouds, rain and thunderstorms.
- Another circulation near the Comorin region is expected to evolve into a fresh low-pressure area by November 25, adding further moisture over the state.
- A third system over the Southeast Arabian Sea is also contributing to unstable atmospheric conditions.
Together, these systems are keeping Tamil Nadu under a prolonged wet spell—bringing heavier rain to the southern districts, while Chennai continues with light to moderate showers and occasional thunderstorms.
