Bihar weather alert: 17 districts face lightning, rain and strong winds
Synopsis
Bihar's Meteorological Department has placed 17 districts on alert for lightning, winds of up to 40 kmph, and light rain on 14 September, with warnings extending to nearly the entire state by 16 September — even as a diverted monsoon trough continues to leave much of Bihar drier than normal.
Key Takeaways
The Meteorological Department issued a weather alert for 17 Bihar districts on 14 September , warning of lightning, winds of 30–40 kmph , and light rain.
A Yellow Alert has been issued for roughly half of Bihar on 15 September , with the Seemanchal region most likely to receive rainfall.
A rainfall warning covers almost all of Bihar on 16 September ; only Buxar, Bhojpur, Arwal, Aurangabad, Rohtas and Kaimur are expected to see near-normal conditions that day.
Bihar is recording below-normal rainfall this monsoon, with meteorologists blaming a low-pressure area over Central India that has diverted monsoon activity away from the state.
The highest temperature on Sunday was 37.9°C in Bhabhua, Kaimur ; the lowest was 24.4°C in Forbesganj, Araria .
Residents, especially in alerted districts, have been advised to avoid exposed areas during thunderstorms and lightning activity.
The Meteorological Department has issued a weather alert for 17 Bihar districts on Monday, 14 September, warning of strong winds, lightning, and light rain across a wide swath of the state. The advisory comes as Bihar simultaneously grapples with intermittent rainfall in some regions and hot, humid conditions in others — an unusual split that meteorologists attribute to a shifting monsoon pattern.
Districts Under Alert
The 17 districts placed under the weather warning are East Champaran, West Champaran, Sheohar, Sitamarhi, Madhubani, Supaul, Araria, Kishanganj, Gopalganj, Saran, Siwan, Buxar, Bhojpur, Arwal, Aurangabad, Rohtas, and Kaimur. Authorities have advised residents in these districts to remain vigilant during thunderstorms and to avoid exposed areas when lightning activity occurs.
According to the Meteorological Department, wind speeds of 30 to 40 kmph are possible in the alerted districts, alongside lightning and light rainfall. Officials have further cautioned that a sudden change in weather could bring light rain even to areas not formally under alert.
72-Hour Weather Outlook for Bihar
The department has issued a 72-hour weather outlook covering conditions up to 16 September. On 15 September, a Yellow Alert has been issued for roughly half of Bihar, with rainfall particularly likely in the Seemanchal region. Isolated light rain is also expected at scattered locations across North Bihar and the southeastern parts of the state.
On 16 September, a rainfall warning has been extended to cover almost the entire state. The only districts projected to see relatively normal weather that day are Buxar, Bhojpur, Arwal, Aurangabad, Rohtas, and Kaimur. Strong winds, lightning, and light rain remain possible across the remaining districts.
Why Bihar Is Seeing Below-Normal Rainfall
Bihar continues to record below-normal rainfall this monsoon season. Meteorologists have attributed the deficit to a low-pressure area that developed over Central India, diverting monsoon activity toward Central India, southeastern Rajasthan, and North Gujarat. The monsoon trough is also currently passing through Central India, further weakening precipitation over Bihar and leaving several areas with only isolated light showers.
Temperatures and Conditions in Patna
The highest maximum temperature recorded on Sunday was 37.9 degrees Celsius in Bhabhua, Kaimur, while the lowest minimum temperature was 24.4 degrees Celsius in Forbesganj, Araria. In the state capital Patna, residents continued to endure hot and humid conditions, with bright sunshine expected on Monday. No specific rainfall alert has been issued for Patna, though officials noted that a sudden weather shift could bring light rain accompanied by strong winds.
As the 72-hour warning period unfolds, residents across Bihar — particularly those in the alerted districts — are expected to monitor local bulletins closely, with conditions forecast to evolve significantly through the middle of the week.
Point of View
Not a routine advisory. The state's persistent rainfall deficit, driven by a low-pressure system pulling moisture toward Central India and Rajasthan, raises questions about groundwater recharge and kharif crop yields that the weather bulletin alone does not address. A 72-hour warning covering nearly the entire state by 16 September suggests the pattern may correct briefly, but the structural monsoon weakness over Bihar this season deserves scrutiny beyond daily alerts.
