Chennai is bracing for significant rainfall today, November 17, 2025, as the India Meteorological Department (IMD) has issued an orange alert for the region. Heavy to very heavy showers are anticipated due to a developing low-pressure system over the Bay of Bengal. In response to the severe weather and resulting waterlogging, authorities have announced a holiday for all government, private, and aided schools in Chennai and several surrounding districts, including Chengalpattu and Tiruvallur. Parents are strongly advised to avoid non-essential travel. While southern Tamil Nadu districts are experiencing milder conditions, the orange alert specifically targets Chennai, Tiruvallur, Kancheepuram, Chengalpattu, Mayiladuthurai, Nagapattinam, Tiruvarur, and Karaikal, forecasting intense rainfall. Other parts of Tamil Nadu are under a yellow alert, indicating expected heavy rain. Temperatures in Chennai are expected to hover around 29-30 degrees Celsius amidst cloudy skies and persistent downpours. Meanwhile, states like Delhi NCR, Uttar Pradesh, and Bihar are reporting normal conditions with no widespread school closures due to weather.
