GRAP 3: Implemented when the AQI is between 401 and 450.
GRAP 4: Implemented when the AQI is above 450.
The maximum temperature for the day is expected to reach 22°C, with cloudy conditions prevailing. Nighttime will also remain cloudy, with a minimum temperature of 12°C. Air quality is forecast to remain hazardous from Sunday morning through late Friday night, prompting officials to continue public health advisories.

In Uttar Pradesh, dense fog continues in the mornings and evenings amid changing weather and dropping temperatures. The Meteorological Department has issued an orange alert for 19 districts in the Terai region for Sunday due to extremely dense fog.
Professor Manoj Kumar Srivastava, a weather scientist at BHU, said that the cold will continue to affect Uttar Pradesh. Over the next 3 to 4 days, both maximum and minimum temperatures are expected to drop further, intensifying the cold. During this period, daytime temperatures are also likely to fall.
According to the Meteorological Department, dense fog is expected in the Terai region of western Uttar Pradesh on Sunday. In eastern Uttar Pradesh, particularly the Purvanchal region, fog is likely to vary from dense to very dense in some areas, leading to reduced visibility.
