Patna: Flooding has intensified across Bihar following heavy inflows from Nepal and breaches in embankments, leaving six districts severely affected, inundating 253 villages and affecting around 3.65 lakh people. Nearly 44,000 people have been forced to leave their homes and take shelter on higher ground, while three youths have died after being swept away by floodwaters.
Embankments have been breached in 10 blocks as swollen rivers put pressure on flood-control structures. The affected districts include Saran, Gopalganj, Muzaffarpur, West Champaran, Vaishali and Bhagalpur, where low-lying areas and riverine settlements have been inundated.
The National Disaster Response Force (NDRF) and State Disaster Response Force (SDRF) teams have been deployed in affected areas. Dry food supplies are also being air-dropped by helicopter to assist people stranded in flood-hit locations.
Embankment Breaches Worsen Flooding in Bihar
Several embankment breaches were reported early Thursday, worsening the flood situation in north Bihar.
In Saran district, the sluice gate of the Saran embankment at Panapur was washed away. A ring embankment was breached in Taraiya, while a 100-metre stretch of the Chharki embankment at Sahebganj was washed away.
In Jaymal Dumri village in the Paroo block of Muzaffarpur district, a breach in the Gandak river embankment led to flooding in surrounding areas.
Saran has reported extensive inundation, with 102 villages across seven blocks submerged. Around 1.70 lakh people have been affected in the district alone.
National Highway 722 in Saran has also been inundated, with reports indicating that water has accumulated to a depth of around five feet in some stretches, disrupting movement and creating difficulties for residents.
Gandak, Ganga and Other Rivers Flow Above Danger Marks
The Gandak, Kosi, Bagmati and Ganga rivers are flowing above the danger marks at several locations in north Bihar, increasing pressure on vulnerable embankments and raising concerns about further flooding.
In Patna district, the Ganga is flowing above the danger mark at Dughaghat, Gandhi Ghat and Hathidah.
Authorities are continuing relief and rescue operations in affected areas. Residents in low-lying settlements and riverine areas remain particularly vulnerable as floodwaters spread.
No Rain Alert for Bihar; Heat and Humidity Likely
Despite the severe flooding, the India Meteorological Department (IMD) has not issued a rain alert for any district in Bihar for Friday, October 2.
According to the forecast, bright sunshine is expected across much of the state, with high humidity likely to cause discomfort during the day. Patna’s maximum temperature may hover around 35°C.
The weather is expected to remain predominantly dry across Bihar until October 4. Light rainfall may occur in some parts of the state thereafter.
Weather experts attribute the expected hot and humid conditions to the absence of a strong weather system capable of producing widespread rainfall, combined with moisture in the atmosphere and intense sunshine.
The lack of rain does not necessarily mean that humidity will decline immediately. Moisture retained in the ground and lower atmosphere, combined with daytime heating, may make conditions feel hotter.
Bihar Weather Forecast for October 2026
The weather is expected to remain warm and humid across much of Bihar during October, as the southwest monsoon typically begins withdrawing from the state around the first week of the month. However, the timing of its withdrawal can vary from year to year.
