The northeastern states are likely to receive widespread and extremely heavy rain during June 24-26 due to an intense monsoon spell, according to the India Meteorological Department.
There is an orange category warning for Assam, Meghalaya, Arunachal Pradesh, Nagaland, Manipur, Mizoram and Tripura along with some parts of sub-Himalayan West Bengal and Bihar for these three days for very heavy to extremely heavy rains.
An orange warning implies that authorities will have to be prepared for rain-related emergencies.
A trough of low pressure currently runs from north Punjab to northwest Bay of Bengal. Its eastern end is very likely to shift northward from June 24. The convergence of strong moist southerlies and southwesterly winds from the Bay of Bengal over northeast and east India is likely to make conditions conducive for extremely heavy rains.
