Guwahati: Northeast India is set to experience a spell of widespread snow and rain, with two western disturbances bringing their influence to bear.
The first, a trough in the middle troposphere, stretches along 60°E north of 30°N, while the second, a cyclonic circulation, lies over north Pakistan and its vicinity in lower levels.
An additional induced cyclonic circulation over central Pakistan in lower tropospheric levels further amplifies the impact.
Snow and Thunderstorms to Blanket Sikkim and Arunachal Pradesh: From February 19th to 21st, Sikkim and Arunachal Pradesh will see widespread snow and rain, accompanied by thunderstorms. This could lead to disruptions in travel and outdoor activities, so residents are advised to stay alert and take necessary precautions.
Scattered Rainfall and Isolated Heavy Snowfall Across Northeast: The influence of the western disturbances extends beyond Sikkim and Arunachal Pradesh. Scattered to fairly widespread light or moderate rainfall or snowfall with thunderstorms and lightning is expected across Northeast India from February 20th to 23rd.
