IMD Weather Today: Various parts of the country are being affected by the weather these days. Due to dense fog, the traffic system from ground to sky has broken down. Due to very low visibility, many vehicles collided with each other on Yamuna Expressway, due to which a major accident occurred. Now weather experts have predicted two types of weather conditions simultaneously. On one hand, the Meteorological Department says that there will be very dense fog in many states from Uttar Pradesh to Madhya Pradesh, Rajasthan, Odisha and North-East. Due to this, normal life is sure to be derailed. On the other hand, due to rapid activation of Western Disturbance, there is a possibility of increase in wind speed. This can provide great relief to millions of people of Delhi-NCR before Christmas. If the mercury falls further due to strong cold winds, there is also a possibility of reduction in air pollution. Due to higher wind speed, a decline in AQI level can be recorded. However, on the morning of Wednesday 17 December 2025, AQI 378 was recorded in Bawana area of Delhi which was in the poor category. Meanwhile, in view of the dense fog, the Indian Meteorological Department (IMD) has asked the people of the concerned states to exercise caution and remain alert.
The cold of December has now started showing its effect in many parts of the country. According to the Meteorological Department, there is a possibility of dense to very dense fog in the morning in many areas of North India, Central India and North-East India between 17 and 21 December. Along with this, cold wave conditions may also arise in some states, due to which normal life as well as road, rail and air traffic may be affected. The Meteorological Department said that there is a possibility of dense to very dense fog in the morning in some areas of Uttar Pradesh and East Madhya Pradesh during December 17 to 20. Especially in Uttar Pradesh, very dense fog may occur at many places on December 17, while this situation may persist in some areas on December 18 also.
