New Delhi, Oct. 22 -- Heavy rainfall in Chennai has paralysed the city, causing flooding, choking roads, and even prompting authorities to close schools today. As the northeast monsoon intensifies amid its early onset, the India Meteorological Department has issued a cyclone warning for Tamil Nadu. The alert comes just hours after the weather agency placed eight districts of the southern state under a red alert - Villupuram, Cuddalore, Mayiladuthurai, Nagapattinam, Tiruvallur, Thanjavur, Pudukottai, and Ramanathapuram. A red alert indicates a heavy rainfall warning.
