The deluge, exacerbated by incessant rain on Wednesday night, has led to severe disruption in regions such as Teesta Bazar and Geil Khola, with roads submerged and houses at the riverbank in peril.

The districts currently submerged in floodwaters include Cachar, Karimganj, Morigaon, Hojai, Nagaon, Dima Hasao, Hailakandi, and West Karbi Anglong. A total of 19 revenue circles in these districts are affected.
