According to a statement issued here by RMC on Wednesday evening, moisture incursion would be there owing to strong low-level Southerly/Southwesterly winds from the Bay of Bengal to Northeast India from September 21 onwards.
“Fairly widespread to widespread rainfall activity with heavy to very heavy rainfall and thunderstorms with lightning at isolated places is very likely to occur over the Northeast region till September 23,” the RMC informed.
As it is, the India Meteorological Department (IMD) has already issued a “yellow alert” over Assam and other parts of Northeast region, predicting heavy to heavy rainfall till September 24.
The yellow alert issued for several districts in Assam indicates heavy rainfall accompanied with thunder and heavy rainfall.
