Over half a million people in villages and cities of Bihar have been severely affected by floods triggered by heavy monsoon rains as all the major rivers continue to swell and overflow.
Further, the flood situation is likely to aggravate with heavy rains in catchment areas of rivers in neighbouring Nepal.
The districts that are facing the worst of nature's fury are Sitamarhi, Sheohar, Muzaffarpur, Bhagalpur, east and west Champaran.
All major rivers in the state, including the Ganga, Bagmati, Koshi, Burhi Gandak and Kamlabalan, continued to rise following heavy rains, according to the central water commission.
The rivers have inundated nearly 500 villages and damaged several embankments and dams across state, particularly in Muzaffarpur and Bhagalpur, said an official on Friday.
Road traffic on many national highways remained paralysed as floodwaters rose to the height of four-five feet.
Floods caused by heavy rains also affected some parts of Patna, Sheikhpura, Begusarai and Nalanda districts.
Thousands of people in Patna suffered due to water logging in the city following incessant rains through the week. Rain and sewage water entered hundreds of houses while several roads were completely submerged.
The heavy rains and waterlogging forced the Patna district magistrate Thursday to order the closure of all schools for two days.
Though the sky remained cloudy with intermittent showers Friday, there was no heavy rainfall.
Nearly 73 percent of the state's area is prone to floods that cause massive damage almost every year, inundating hundreds of villages, killing several people and damaging crops and property.
