IMD Weather Alerts for Rain and Snowfall
The India Meteorological Department (IMD) has issued a series of alerts for heavy rainfall and snowfall across various regions in India from November 10 to November 16, 2026. This weather phenomenon is primarily attributed to a western disturbance affecting the Western Himalayan region. According to the IMD, isolated to fairly widespread rain and snowfall is expected in the western Himalayan region until November 13, with heavy precipitation anticipated in the Kashmir Valley on November 12.
The IMD's forecast indicates a low-pressure area forming over the southeastern Bay of Bengal around November 13, which is expected to move northwestward and intensify into a well-marked low-pressure area within the next 24 hours. This development could lead to further weather changes across the country, particularly in the southern states.
Regional Weather Impacts and Forecasts
The IMD has highlighted specific regions that will experience significant weather changes. Heavy rainfall alerts have been issued for Tamil Nadu, Puducherry, and Karaikal on November 10 and 11, as well as on November 15 and 16. Additionally, Kerala and Mahe are expected to receive heavy rainfall on November 16. The IMD has also predicted isolated to scattered rainfall over Jammu-Kashmir-Ladakh-Gilgit-Baltistan-Muzaffarabad during November 10-11 and November 14-16, with Himachal Pradesh and Uttarakhand experiencing similar conditions during November 10-16.
The forecast also warns of isolated heavy rainfall in northeastern states, including Nagaland, Manipur, Mizoram, and Tripura on November 10. Moderate to intense lightning is expected over Meghalaya, Mizoram, and Tripura on November 10 and 11, which could pose risks to local populations and infrastructure.
Delhi's Air Quality Improves
In conjunction with the weather alerts, Delhi's air quality has shown signs of improvement, moving from the 'very poor' category to 'poor' with an Air Quality Index (AQI) of 299. This improvement follows a spike in pollution levels post-Diwali, where the AQI reached as high as 376. The Central Pollution Control Board (CPCB) reported that wind speed increases have contributed to this positive change in air quality.
Despite the improvement, 23 monitoring stations across Delhi still recorded 'very poor' air quality, with Pusa Road and Chandni Chowk reporting AQIs of 385 and 381, respectively. The CPCB categorizes AQI levels as follows: 0-50 is 'good', 51-100 is 'satisfactory', 101-200 is 'moderate', 201-300 is 'poor', 301-400 is 'very poor', and 401-500 is 'severe'. The ongoing weather changes may further influence air quality in the coming days.
Temperature Trends and Fog Conditions
The IMD has forecasted that Delhi will experience partly cloudy skies, with shallow to moderate fog expected in the mornings. The maximum temperatures are predicted to range between 27°C to 29°C, while minimum temperatures will hover between 14°C to 16°C. These temperature trends, combined with the expected rainfall, may further impact the air quality and visibility in the region.
Summary of Weather Alerts and AQI Changes
The IMD's comprehensive forecast highlights the significant weather changes expected across India, particularly in the context of the ongoing western disturbance and the formation of a low-pressure area. The alerts for heavy rain and snowfall, coupled with the improvements in Delhi's air quality, underscore the dynamic nature of India's weather patterns during this period.
The IMD's forecasts and alerts serve as critical information for residents and authorities, aiding in preparedness for the upcoming weather events. As the situation develops, continuous monitoring will be essential to mitigate any adverse impacts on public health and safety.
