Mussoorie/Haridwar, Aug. 22 -- The Char Dham Yatra was disrupted on Thursday after overnight rainfall triggered multiple landslides across the state, leaving 155 roads blocked. The India Meteorological Department (IMD) has issued an orange alert for four districts, warning of heavy to very heavy rainfall on Friday and Saturday. In Chamoli, the Badrinath National Highway was blocked at Kamera, Bhanerpani, and Pagal Nala after heavy rains caused boulder falls and landslides around 6.30 am. The National Highways Authority personnel cleared the blockages after more than three hours of effort, allowing stranded pilgrims to resume their journey. In Uttarkashi, the Gangotri highway, already damaged at multiple spots since the August 5 Dharali disaster, was blocked near Dharasu and Songad.

District Disaster Management Officer Shardul Gusain said, "Authorities are working swiftly. A section of the Gangotri highway near Dharasu has reopened, while work on Yamunotri's blocked stretches at Kuthnaur and Naradchatti was completed after two hours of effort." The met department on Thursday issued an orange alert for heavy to very heavy rainfall in Bageshwar and Champawat on Friday, warning of extremely intense spells at isolated spots.
