Patna: Storms and heavy rainfall have swept across Bihar over the past 24 hours, with the India Meteorological Department warning that adverse weather conditions are likely to continue in parts of the state on Sunday.
Districts including Sitamarhi, Sheohar, Madhubani, Supaul, Araria and Kishanganj are expected to experience strong winds of up to 50 km/h, accompanied by thunderstorms and heavy rain. Authorities have advised residents in these areas to avoid stepping outdoors unless necessary.
Sharp temperature drop
The sudden change in weather has led to a steep fall in temperatures across the state, with daytime temperatures dropping by up to 14°C in some districts.
Cities such as Araria, Muzaffarpur and Patna recorded significant declines, bringing a brief return of cooler conditions despite the onset of March.
Meteorologists attributed the change to a cyclonic circulation over eastern Bangladesh, combined with a strong westerly jet stream.

Mixed conditions across state
While northern districts remain under alert, other parts of Bihar are expected to see dry weather and rising temperatures, with sunshine likely to return in the coming days.
The weather department has forecast a gradual increase in temperatures from March 23 to March 25, as conditions stabilise across the state.
More changes ahead
However, officials said the relief may be temporary, with another western disturbance expected to become active from March 26, potentially bringing fresh spells of wind and light rain.
Air quality improves
The recent rainfall has also led to a significant improvement in air quality. Patna’s air quality index dropped to 44, while cities such as Bhagalpur and Gaya recorded even lower levels, indicating cleaner air conditions.
Officials said the rains helped settle dust particles, offering short-term environmental relief alongside the cooling effect.
