The India Meteorological Department (IMD) has predicted widespread to very heavy rainfall in several Northeastern states until July 14. Assam, Meghalaya, Arunachal Pradesh, and Tripura are expected to experience intense rain spells, leading to weather alerts in the region. Heavy to very heavy rainfall, including extremely heavy rainfall in isolated areas, is likely over Assam and Meghalaya on Wednesday and again from July 10-14.
Fresh heavy rain has caused flash floods and landslides in various districts of Arunachal Pradesh, affecting over 94,200 people across 26 districts. Changlang district experienced heavy rainfall resulting in landslides and flooding, while Upper Subansiri and Upper Siang districts were severely impacted by floods and landslides. A rockfall incident due to continuous rainfall was reported in East Kameng district.
In Tripura, the IMD’s Meteorological Centre in Agartala issued an Orange Warning for Wednesday for West Tripura, Khowai, Dhalai, and Gomati districts due to the possibility of heavy to very heavy rainfall at isolated places. The remaining four districts received a Yellow alert, forecasting heavy rainfall at isolated locations. Normal life was disrupted in parts of Tripura following heavy rainfall, leading to waterlogging in low-lying areas and disruptions in traffic movement.
The Southwest Monsoon entered substantial parts of the Northeastern region on June 7, slightly later than its normal onset date. Despite the current widespread rainfall, seven of the eight northeastern states, excluding Sikkim, faced significant rainfall deficiency in June due to weak rain-bearing systems over the Bay of Bengal, inactive monsoon troughs, and El Nino conditions. The IMD data revealed a rainfall deficiency of over 40% in the northeastern region during June, the first month of the Southwest Monsoon season.
