A powerful western disturbance is activating over the Himalayan regions starting today, leading to heavy snowfall in mountainous areas and rainfall in the plains. Delhi-NCR continues to face dense fog and severe air pollution, with AQI levels remaining in the 'severe' category.
Reporting from New Delhi on January 19, 2026: A strong western disturbance is becoming active over the Himalayan regions starting today. According to the weather department, heavy snowfall is expected in Jammu and Kashmir, Himachal Pradesh, Uttarakhand, and Leh-Ladakh on January 20. In recent years, weaker disturbances had led to minimal snowfall in these areas, but conditions are now shifting.
The impact on the plains will be felt between January 23 and 25, with good rainfall possible in Delhi, Punjab, Haryana, and Rajasthan. Two consecutive western disturbances are incoming, intensifying the winter.
Meanwhile, dense fog and pollution have worsened conditions in Delhi-NCR. The Central Pollution Control Board (CPCB) reports Delhi's average AQI reaching 444, in the 'severe' category, though some accounts note it at 418. Levels hit 434 at ITO and 417 near Rafi Marg. Noida recorded 430 and Gurugram 378. Low wind speeds and cold have trapped pollutants near the ground.
Consequently, GRAP-4 measures include a ban on construction, hybrid operations for schools and offices, and restrictions on polluting vehicles. Flights at Indira Gandhi International Airport faced delays due to fog. The weather department issued a yellow alert, with minimum temperature at 5.3 degrees Celsius. Health experts advise limiting outdoor activities.
