The convergence of moist southwesterly winds in the lower levels aided by favourable upper-level wind pattern is likely to cause scattered to fairly widespread rain/thundershowers over Northeast India (Arunachal Pradesh, Assam & Meghalaya and Nagaland, Manipur, Mizoram & Tripura) and Eastern states (West Bengal, Sikkim, Odisha, Jharkhand and Bihar) during next 5-7 days, reported Indian Meteorological Department weather forecast morning bulletin. Moreover, thunderstorms accompanied by lightning and occasional thunder squalls (wind speed 50-60 kmph and more), hailstorms at isolated places are also likely over these regions during this period.
Heavy rain along with hail & gusty winds to lash over Western Himalayan Region and Plains of Northwest India
