Reason for heavy rain
The well-marked low over Odisha and westcentral Bay of Bengal has been there for about 5 days and is moving across Odisha, Bengal, Bihar, Northeast India and Bangladesh. During retreating monsoon these systems have a tendency to recurve and go towards East and Northeast India giving spells of heavy rain, which is exactly the case at the moment.
Forecast
Meanwhile, rainfall is going to reduce in intensity as well as in spacial coverage over the next two days. However, flood situation may continue as rivers keep responding even after cessation of rain. Overall improvement in the condition is possible only by the weekend, when rain will become minimal and river waters will start receding.
