The north-eastern states of Assam, Meghalaya, Arunachal Pradesh and Sub-Himalayan West Bengal and Sikkim will receive heavy to very heavy rainfall till May 20, due to strong south-westerly winds from the Bay of Bengal to the northeast and the adjoining east Indian states at lower tropospheric levels.
The Met Department has issued a red alert in Assam and Meghalaya on Tuesday, advising residents to take precautionary measures against the hazardous weather conditions. The rest of the north-eastern states are under orange or yellow watch.
The heavy downpours have triggered flash floods and landslides in many districts of Assam, especially in Dima Hasao, where the situation has turned from bad to worse. Meteorologists said the north-eastern states can expect precipitation up to 50-80 mm/day for the whole week.
The Assam State Disaster Management Authority reported at least three people were killed in the Dima Hasao district of Assam and nearly 57,000 people from 222 villages have been affected due to rain-related incidents, including landslides.
Assam and Meghalaya have recorded surplus rains of 43% to 53% higher than their respective averages between March 1 and May 15.
