Thursday, August 5: Parts of Northeast India are set to experience a spike in rainfall activity this weekend, as heavy monsoon showers have been forecast across the region on August 7-8.

As per The Weather Channel’s met team, the cyclonic circulation that has been present over Bangladesh for the past few days is expected to gradually move westwards.

Once it shifts away, moist southwesterly winds from the Bay of Bengal will start flowing into Northeast India, strengthening the rainfall activity over the region from Friday night to early next week.

Accordingly, the India Meteorological Department (IMD) has predicted isolated heavy to very heavy falls over the northeastern states on Saturday and Sunday, August 7-8.

The IMD’s regional met centre based in Guwahati adds that the likes of Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram and Tripura will start experiencing moderate showers and thunderstorms from Thursday itself.

The isolated heavy to very heavy showers that are on the horizon may remain restricted to just Assam and Meghalaya over the weekend.

In view of these predictions, the IMD has issued a yellow watch over Assam, Meghalaya, and N.M.M.T. for Thursday and Friday; over Assam and Meghalaya on Saturday; and over Arunachal Pradesh, Assam and Meghalaya on Sunday and Monday. The advisory urges residents to ‘be aware’ of the local weather situation.

Overall, the weather.com meteorologists expected daily rainfall of 30-50 mm to continue over the region for this forecast period.

Meanwhile, over the past one week, the monsoon activity over the Northeast has been fairly normal. Between July 29 and August 4, Assam and Meghalaya collectively received 91.7 mm rainfall, the N.M.M.T. subdivision recorded 72.3 mm precipitation, while Arunachal Pradesh experienced rains worth 45.7 mm.

As for the seasonal precipitation, all three subdivisions have received below-average rainfall since the monsoon period began in June. Between June 1 and August 4, Assam and Meghalaya received 844.3 mm rains (a 24% deficit compared to long-term average), N.M.M.T. recorded 559.7 mm (33% deficit) and Arunachal registered 666.5 mm (37% deficit).
