The India Meteorological Department (IMD) has issued a weather warning that includes heavy rainfall and fog for various regions in India over the upcoming week. A depression has developed in the central South Bay of Bengal and the adjacent East Equatorial Indian Ocean, which is forecasted to strengthen into a deep depression within the next 24 hours. This meteorological system is moving northwest and is expected to bring heavy to very heavy rainfall to coastal Tamil Nadu and Puducherry on November 26 and 27, with certain areas possibly experiencing extremely high rainfall totals. Rainfall activity is anticipated to persist in these areas on November 28, accompanied by additional heavy rain in some localities. Additionally, South Coastal Andhra Pradesh may see isolated heavy rainfall from November 26 to 29.

The IMD also forecasts dense fog conditions in parts of northern India, particularly affecting isolated locations in Himachal Pradesh, from November 26 to 30. The dense fog is likely to impact regions such as Punjab, Haryana, Chandigarh, and Uttar Pradesh between November 28 and December 1.

Furthermore, a gradual decrease in minimum temperatures by 2-3 degrees Celsius is expected over northwest India, excluding Rajasthan, in the forthcoming days. A similar trend is forecast for Maharashtra, while no significant temperature variations are projected for other regions of the country during this timeframe.

As for air quality, Delhi is grappling with alarming pollution levels, with the capital’s 24-hour average Air Quality Index (AQI) reaching 349 on Monday, a rise from 318 the previous day. According to the SAMEER app that tracks the National Air Quality Index, the AQI was measured at 218 in the morning but soared to 377 by the evening due to inadequate wind speeds. By the end of the day, 14 out of Delhi’s 38 air quality-monitoring stations recorded AQI levels categorized as “severe.” The Central Pollution Control Board (CPCB) confirmed Delhi’s alarming AQI measures, highlighting the persistent air quality crisis.

Environmentalist Bhavreen Kandhari contextualized the rise in AQI levels, attributing it to stagnant winds with speeds below 10 km/h and falling temperatures, which effectively trap pollutants close to the ground.

In Tamil Nadu, significant rainfall is anticipated over the next five days, commencing November 26, due to the deep depression nearing the Sri Lanka-Tamil Nadu coasts, as reported by the Regional Meteorological Centre (RMC) in Chennai. Under the influence of this system, heavy rain is expected in certain isolated locations in the districts of Ramanathapuram, Tiruchirappalli, Perambalur, Kallakurichi, and Chengalpattu.

The RMC also warns of heavy to very heavy rainfall at some locations, with instances of extremely heavy rainfall likely at one or two spots, particularly in the Cuddalore, Mayiladuthurai, and Karaikal regions. Other districts that might experience very heavy rainfall include Ariyalur, Tiruvarur, Nagapattinam, Thanjavur, Pudukkottai, Villupuram, Puducherry, Sivaganga, Chennai, Kancheepuram, Tiruvallur, Ranipet, and Tiruvannamalai, as per the bulletin issued by the RMC.
