What Triggered the Disruptions in Deomali
Incessant heavy rainfall caused the Chatjo River to swell and overflow its banks. This natural surge directly impacted low-lying zones and connectivity routes in the town. The flooding resulted in waterlogging and structural damage to public assets.
Context (general): Arunachal Pradesh, like many Himalayan and northeastern areas, experiences intensified monsoon rains that can challenge local infrastructure due to terrain and river systems. This is a recurring seasonal pattern.

A private school in Deomali also suffered damage from the heavy rainfall and associated flooding. Connectivity issues hindered normal routines, with residents facing challenges in accessing essential services and transportation.
