A total of 5.5 million people have been affected by the natural disaster, local authorities were cited as saying by the India TV broadcaster. Karimganj and Cachar districts of the state are among the worst hit areas.
The floods were reportedly caused by heavy rains continuing for over two weeks, as a result of which the Brahmaputra and Barak rivers burst their banks and flooded most of the state. By June 19, 528.5 millimeters (20.8 inches) of rain or 109% monthly average, fell in the state, the Indian meteorological department said.
In addition, the flood damaged over 100,000 hectares of crops, according to the Indian authorities. Moreover, several trains were canceled, stopped for a short time or rerouted.
Local authorities plan to announce a relief package soon to help all those affected, Chief Minister Himanta Biswa Sarma was quoted as saying by the broadcaster.
Earlier in June, Debabrata Saikia, the opposition leader in Assam's parliament, requested an aid package of at least 200 billion rupees ($2.5 billion) from the country's government for reconstruction works and urged the authorities to declare a state of national disaster.
