A grave weather crisis has severely impacted Himachal Pradesh, leaving districts like Mandi and Kullu paralysed as incessant rainfall triggers widespread landslides and flash floods. Transportation and essential services have ground to a halt, with over 482 roads closed, including four National Highways — the Chandigarh–Manali highway, NH-154A (Chamba–Pathankot), NH-305, and NH-21 — all blocked due to landslides at multiple locations.
Mandi district alone has seen 333 roads rendered impassable, and over 2,000 vehicles are currently stranded. The Mandi–Kullu National Highway via Pandoh remains shut following a landslide near Jhalogi, while the alternative route via Kamand–Kataula is also blocked near Kalauj. As a result, all road access to Kullu has been cut off.
Due to heavy rains, Karsog has also been cut off from Shimla and the district headquarters Mandi, as both the Karsog–Shimla road via Tattapani and the Karsog–Mandi road via Rohanda are blocked.
Additionally, the Chamba–Pathankot highway was blocked when a hillside collapsed near the Nalda bridge at Bathri, stranding numerous pilgrims and other travellers. Long queues of vehicles were seen along the affected stretches. Meanwhile, the Manimahesh Yatra has been suspended following a landslide near Sundrasi on the pilgrimage route.
According to reports, since June 20, Himachal Pradesh has reported 79 landslides, 77 flash floods, and 40 cloudbursts. Though no casualties have been reported so far, flash floods and landslides in districts such as Chamba and Kullu have led to considerable damage to infrastructure and private property.
Though Mandi and Kullu experienced temporary relief with clear skies on Wednesday, August 27, the situation remains precarious. The India Meteorological Department (IMD) has issued a red alert for Chamba, Kangra, and Mandi for the next two days. A yellow alert for heavy rainfall is in effect for Chamba, Lahaul-Spiti, Kangra, Kullu, and Mandi on August 28, and for Shimla and Mandi on 29 August. An orange alert has also been issued for August 30–31 in Mandi, Shimla, and Solan, while Kullu, Mandi, Kangra, and Shimla will continue under the same alert on 31 August.
According to reports, Himachal Pradesh has incurred losses amounting to Rs 2,394 crore so far this monsoon. Between 20 June and 25 August, 306 lives have been lost due to landslides, flash floods, and related accidents. Additionally, 367 people have sustained injuries, and 38 individuals are still reported missing.
Authorities continue to monitor the situation closely as weather conditions remain unpredictable and dangerous across the region.
The impact of climate change is increasingly evident in Himachal Pradesh and Uttarakhand, largely due to their geographic and ecological sensitivity. Experts have long warned against unrestrained construction in Himachal’s fragile mountainous terrain. Despite high vulnerability to landslides, flash floods, and soil erosion, development—fuelled by tourism and urban sprawl—continues unchecked.
The Himalayas, among the world’s most ecologically fragile regions, face mounting threats due to steep gradients, young geological formations, and climate variability.
Himachal Pradesh’s fragile mountainous terrain, combined with unregulated construction, deforestation, and climate change, has significantly increased its vulnerability to natural disasters. Steep slopes, unstable soil, and heavier buildings contribute to slope destabilisation, often triggered by intense rainfall.
Modern concrete structures are far heavier than traditional wooden houses. Built on unstable slopes, these structures put excessive pressure on loose soil, disrupting the natural balance. Over time, this leads to slope failure, land subsidence, and landslides, particularly during heavy rainfall.
Reports say that geologists and environmentalists have described Himachal’s development as “unscientific, unsustainable, and foolish.” They warn that continued disregard for ecological limits could cause irreparable environmental damage and threaten the state’s long-term stability.
The IPCC reports that the Himalayas are among the most climate-vulnerable regions. Increased precipitation over shorter periods is a growing trend, leading to flash floods and rapid saturation of soil. This further destabilises already weakened slopes and infrastructures.
Ignoring warnings has led to the collapse of thousands of buildings, bridges, loss of biodiversity, and disruption of local livelihoods. Recent incidents, such as the sinking land in Shimla and building collapses in Kullu, show that without immediate corrective action, both human life and the environment remain at grave risk.
