At least 13 persons have died after buildings collapsed and trees fell on them due to incessant rain in Patna, Bhagalpur and Kaimur districts of Bihar.
The three districts are among over a dozen in the state that were lashed by incessant rain for close to 48 hours bringing normal business to a grinding halt and disrupting rail and road traffic in most places.
According to weather department, the state capital has received more than 200 mm of rainfall since Friday evening, which was described by Principal Secretary, Disaster Management department, Pratyay Amrit as "totally unexpected".
He also expressed concern over water having entered many power sub-stations which could affect the functioning of sump houses in the long run.

I would appeal to the people of the state to have patience and courage. Torrential rain have followed a prolonged dry spell which vindicates our governments resolve to combat climate change through environmental preservation."
