The Flood Forecasting and Warning Centre said, water may increase over the next three days, raising the risk of short-term flooding in seven northern districts, including Rangpur and Kurigram. 

However, heavy rain upstream in India's West Bengal and Sikkim is expected to increase the flow of the Teesta River. 

Although water at the Teesta Barrage is now 18 centimeters below the danger level, officials say it could rise above the danger mark within the next three days.
