Heavy Rainfall Likely to Lash Assam, IMD Issues Yellow, Orange Alert For Several Parts

The Assam region will experience rainfall over the next 4-5 days, with isolated areas experiencing extremely heavy to very heavy rains, according to the India Meteorological Department (IMD).

Yellow and orange advisories have also been issued in some areas of Assam for the upcoming few days by the principal agency in charge of meteorological monitoring, weather forecasting, and seismology.

According to a report shared by the Regional Meteorological Centre, the low-pressure area that was over south Jharkhand and the neighbouring states of north interior Odisha, north Chhattisgarh, and north Jharkhand is now over north Chhattisgarh and its surrounding areas, with the cyclonic circulation that goes with it extending up to 5.8 km above mean sea level and tilting southward with height. Within the following 24 hours, it is predicted to move across northeast Madhya Pradesh in a west-northwesterly direction.

It also mentioned that the Monsoon Trough currently stretches up to 1.5 km above mean sea level and moves southeast to northeast Bay of Bengal, passing through Ganganagar, Narnaul, Datia, Satna, the heart of the Low-Pressure Area over north Chhattisgarh & vicinity, Keonjhargarh, and Balasore.

“From August 21 onward, the eastern end is most likely to move north of its usual position. Strong low-level winds from the Bay of Bengal to Northeast India are quite likely to bring moisture into the region. In the Assam region over the next 4-5 days, rainfall is very likely to occur at many locations to most locations with isolated heavy to very heavy rains,” IMD report reads further.
