The flood situation in northern part of Bengal showed an overall improvement, barring Malda district where nearly five blocks were still inundated by the increasing water level of the Mahananda river.
Floods wreaked havoc in Cooch Behar, South Dinajpur, North Dinajpur, Jalpaiguri, Alipurduar and Malda, affecting over 50 lakh people.
The Chief Minister interacted with victims and assured them of relief. She also instructed district officials to deal with the disaster promptly.
"This situation is due to the water level of the river," she told locals.
According to the State Irrigation Department, heavy downpour in Nepal and Bihar is further worsening the situation as the waters released by them is entering Mahananda.
They said the Mahananda was flowing 1.5 metres above the extreme danger level in the English Bazar area while some other rivers in the area have also breached the danger level.
According to the district administration in Malda, nearly eight lakh people are affected by the flood.
Ms Banerjee earlier alleged floods in southern West Bengal districts were "man-made" and held the Centre and the Damodar Valley Corporation (DVC) responsible for the disaster.
