Patna: Cold weather has made a brief comeback in Bihar, prompting the India Meteorological Department (IMD) to issue a yellow alert for dense fog in 12 districts, including West and East Champaran.
The weather office said foggy conditions were likely to affect large parts of north Bihar during the morning hours, with visibility in several areas expected to remain between 50 and 200 metres. Districts under the fog alert include West Champaran, East Champaran, Gopalganj, Siwan, Saran, Sitamarhi, Sheohar, Madhubani, Supaul, Araria, Kishanganj, Darbhanga, Muzaffarpur, Vaishali and Samastipur. A light haze is expected in the remaining districts.
Meteorologists warned that reduced visibility could disrupt road traffic, particularly on highways and in open areas, and urged drivers to exercise caution. Fog may thin out as the day progresses, but fully clear conditions are unlikely in the short term.
A slight dip in night temperatures was recorded over the past 24 hours due to cold winds, though the IMD said there were no signs of a cold wave or cold day conditions returning. Clearer skies and sunshine over the coming days are expected to help temperatures recover gradually.

Light rain is forecast on February 3 in parts of southwestern Bihar, including Bhojpur, Buxar, Kaimur, Rohtas, Aurangabad and Arwal. A marginal fall in temperature may be recorded in these areas, while the rest of the state is expected to remain dry.
In the capital, Patna, light to moderate fog is likely in the morning, followed by limited sunshine during the day. Minimum temperatures are expected to hover between 10 and 12C, with maximum temperatures around 20 to 22C.
According to the IMD forecast, there will be little change in temperatures over the next 24 hours. However, a rise of 3–5C in maximum temperatures and 2–4C in minimum temperatures is likely over the following 48 hours. Until then, dense morning fog is expected to continue causing inconvenience across several parts of the state.
