Guwahati, Sept 20: The Regional Meteorological Centre (RMC) here has forecast increased rainfall activity across parts of the Northeast for the next three days.
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.
It may be noted that heavy rainfall accompanied by thunder and lightning lashed Guwahati with water-logging reported from several areas of the city on Tuesday evening.
According to the IMD report, a low pressure area has been formed over northwest Bay of Bengal and adjoining West Bengal-north Odisha coasts and the associated cyclonic circulation extending up to 7.6 km above mean sea level tilting southwestwards with height. “It is likely to move northwestwards across Jharkhand,” the IMD report stated.
