The Indian Meteorological Department (IMD) has predicted that rainfall with isolated heavy showers in Assam will continue until May 22nd. In addition, Meghalaya – who is also suffering from the monsoon – will see heavy rainfall on May 21 and 22, the Met department said in its latest bulletin. The same weather alert was issued for Sikkim and sub-Himalayan West Bengal until 22 May.
However, the IMD said that the intensity of precipitation will decrease significantly across northeast India by 22 May.

The Met department said precipitation will be triggered by a wet atmosphere currently prevailing over the north-west and east Indies, and will dominate until May 24. Furthermore, thunderstorm activity will increase across the regions between 22 and 24 May.
At the same time, there is a western disturbance over northeastern Afghanistan and nearby. Another western disturbance is expected to affect northwestern India beginning May 22. “The east-west trough is likely to reappear at the lowest levels in northern India,” the IMD bulletin said.
Under the influence of these conditions, as many as 15 states and territories of the Union (UTs), including northeastern and eastern regions, will witness by May 25 thunderstorms with thunderstorm activity and hailstorms.
The forecast comes even as heavy downpours hit Assam for the eighth consecutive day, affecting a total of 29 districts and increasing the death toll to 15 so far. According to a bulletin from the Assam State Disaster Management Authority (ASDMA), 2,251 villages in 84 revenue districts of the state have been hit by floodwaters.
Images flooded by social media showed National Disaster Response Force (NDRF) personnel wading through deep water to rescue people from their homes that were almost completely flooded. Teams from the Indian Army and State Disaster Response Force (SDRF) are also deployed to provide assistance.
Here are the latest IMD alarms for 15 states and UTs through May 25:
