Patna: Bihar is expected to see a shift in weather from April 25, with storms and rainfall forecast to bring some respite from an intense heatwave that has gripped the state in recent days. However, high temperatures are likely to persist in parts of southern Bihar even as conditions begin to change elsewhere.
The India Meteorological Department (IMD) said a low-pressure system has developed over Bihar and neighbouring regions, including Jharkhand and West Bengal, which is set to alter weather patterns over the coming days. The system is expected to trigger thunderstorms, gusty winds and rainfall across much of the state for four to five days.
In northern districts, storms and rain are likely to begin on Saturday, with conditions gradually extending to southern areas from April 27. The IMD has issued a yellow alert for several districts in north Bihar, including East Champaran, Shivhar, Sitamarhi, Madhubani, Supaul, Araria and Kishanganj, warning of thunderstorms, lightning and wind speeds of up to 50km/h.
At the same time, heatwave conditions are expected to continue in parts of south Bihar, including Gaya, Nawada, Aurangabad, Rohtas and Kaimur, highlighting a sharp contrast in weather across the state.
On Sunday, weather activity is forecast to intensify, with an orange alert issued for 13 districts in north Bihar. Heavy rainfall, thunderstorms and lightning are expected in areas including Sitamarhi, Muzaffarpur, Darbhanga, Samastipur, Purnia and Kishanganj. A yellow alert will also remain in place for districts such as Saran, Siwan, Gopalganj and Champaran.
By April 27 and 28, the impact of the system is expected to be felt across Bihar, with widespread rain, gusty winds and lightning forecast in several districts, including Patna, Bhagalpur and Gaya. The change in weather is likely to bring a fall in temperatures, offering some relief after days of oppressive heat.
On Friday, Dehri in Rohtas district recorded the state’s highest temperature at 44C. Temperatures in Patna, Aurangabad, Nalanda, Jehanabad and Chapra also exceeded 40C. Night-time conditions have offered little respite, with temperatures remaining between 22C and 27C.
The IMD has urged residents to exercise caution during storms and lightning, advising people to avoid open areas and shelter under secure structures. In heatwave-affected districts, authorities have recommended limiting outdoor activity during peak daytime hours and maintaining adequate hydration.
