Bihar is one of the most flood-prone states of our country. Inhabitants of north Bihar lives under the recurring threat of flood devastation. Historical data holds that about 16.5% of the total flood affected area in India is located in Bihar. In the years 1978, 1987, 1998, 2004 and 2007 Bihar witnessed high magnitudes of flood.
Several places in Bihar, situated along the foothills of Himalayas generally face the flood fury due to heavy rains in Nepal.
The plains of Bihar and adjoining areas of Nepal are drained by a number of rivers, which have their catchments in the steep and geologically nascent Himalayas. Rivers like Kosi, Gandak, Burhi Gandak, Bagmati, Kamla Balan, Mahananda originate in Nepal and usually drops down a lot of sediment load in the plains of Bihar.
The low pressure area over northwest and adjoining westcentral Bay of Bengal and Odisha, north Andhra Pradesh coast now lies as a well-marked low pressure area over northwest Bay of Bengal and adjoining coastal areas of Gangetic West Bengal, Odisha, north Coastal Andhra Pradesh and westcentral Bay of Bengal. This system has been bringing heavy showers over Nepal and north Bihar.
Heavy to very heavy rain in Nepal could lead to a sharp rise in the water level of Kosi River and its tributaries. Thereby, several districts of Bihar including Kishanganj, Madhubani, Sitamarhi and Motihari should prepare for floods.
According to the latest weather update by Skymet Meteorology Division in India, Sub Himalayan West Bengal and Sikkim, along with other states of Northeast India will also receive rain for at least next 48 hours.
