The heaviest rains in a decade have left a third of Bangladesh underwater affecting millions of people. The rains have swollen two main Himalayan river systems - the Brahmaputra and the Ganges - that flow through India and Bangladesh.

The Brahmaputra river is almost 40cm higher than normal and threatening to burst its banks in a number of locations. 15,000 people have already evacuated from flooded areas, and if rivers continue to swell the number of evacuations would increase dramatically.

Weather forecasts for the next 10 days are for further heavy rain. Officials in Bangladesh expecting the situation to worsen, as Covid-19 and weather conditions affect relief efforts.
