In early October 2025, Bihar and eastern Uttar Pradesh were struck by an unprecedented weather event. The India Meteorological Department (IMD) issued a red alert as the region experienced extremely heavy rainfall, with some areas recording over 210 mm in just 24 hours. This deluge has led to widespread flooding, loss of life, and significant infrastructure damage.
A Record-Breaking Downpour
The IMD reported that districts like Siwan, Gopalganj, East Champaran, and Bhojpur received rainfall amounts ranging from 230 mm to 320 mm on October 4. These figures are 300% to 600% above the normal rainfall for this time of year. Varanasi in neighboring Uttar Pradesh also set a new record, with 190 mm of rain, making it the wettest October day in the city’s history.

Human Toll and Infrastructure Collapse
The relentless rain has claimed at least 10 lives across Bihar. Seven fatalities were due to lightning strikes, while three others died from storm-related incidents. The worst-hit districts include Vaishali, Rohtas, Muzaffarpur, West Champaran, Bhojpur, Jehanabad, Kishanganj, and Arwal.
In Patna, a portion of the Mithapur flyover collapsed after hours of heavy rainfall, highlighting the vulnerability of urban infrastructure. Additionally, roads in Sitamarhi, Darbhanga, and Muzaffarpur have been submerged, disrupting daily life and hindering rescue operations.
Rivers in Fury
The Kosi River, known for its unpredictable behavior, has breached its banks, inundating 105 villages in Supaul district. The rising water levels have caused extensive damage to homes, agricultural land, and infrastructure, displacing thousands of residents.

Relief Efforts and Forecast
The IMD has forecast a reduction in rainfall over the coming days, providing some relief to the affected regions. However, the damage caused by the deluge will require sustained efforts for recovery. Authorities are focusing on rescue operations, providing shelter, and restoring essential services to the affected populations.
Looking Ahead
As Bihar grapples with the aftermath of this unprecedented rainfall, the event underscores the urgent need for improved infrastructure, better flood management systems, and enhanced disaster preparedness. The resilience of the affected communities and the swift response from authorities will be crucial in the coming days as they work towards recovery and rebuilding.
