Arunachal Pradesh has been hit by severe disruption following days of relentless monsoon rain and repeated cloudburst incidents, leaving several areas cut off from the rest of the state. The latest spell of extreme weather, the second major cloudburst reported within a week, has caused widespread flooding, landslides and extensive damage to roads and public infrastructure, particularly in East Siang and Leparada districts.

According to district authorities, nine key roads in East Siang, considered vital lifelines for local communities, have either been washed away or blocked by landslides. Several residents stranded in flood-hit areas have been rescued, while many villages remain isolated due to damaged transport links. The India Meteorological Department (IMD) has issued red alerts for several districts and warned of continued heavy rainfall, with more than 200 mm of rain expected by Monday. The state government has advised people to avoid unnecessary travel and follow official weather advisories.

Road Connectivity Severely Affected

Restoration work is underway, but continuous rainfall has slowed clearance operations. Emergency Response Teams have managed to reopen only two of the eleven major roads affected—the Terang-Korang-Mebo Road and the JNC Lower Campus to Upper Campus Road. Several important routes, including Pasighat-Pangin, Mariyang-Yingkiong and Mebo-Dambuk-Bomjir, remain completely closed due to massive landslides and mudslides.

Infrastructure has suffered extensive damage, with the Pasighat-Ranne-Takilalung Road among the worst affected. The left span of the Letang Bridge has been washed away by floodwaters, cutting off traffic entirely. Authorities have also announced the temporary closure of the Pasighat-Yagrung-Ledum-Ten (PLT) Road until further notice.

Authorities Urge Public to Stay Alert

Heavy machinery has been deployed to clear debris, while highway officials continue restoration efforts on a war footing. However, recurring landslides along National Highway-13 between Renging and Yembung continue to disrupt movement. The administration has urged residents to avoid non-essential travel, drive only during daylight hours, stay away from landslide-prone areas and swollen rivers, and avoid parking vehicles near unstable hill slopes until weather conditions improve.
