Record Humla Rains and Snow Sever Border Road in Deadly Karnali Deluge
Simkot has experienced its heaviest rainfall since 1978 as late-monsoon downpours and unseasonal snow sever Humla's link to the northern border and push Karnali's disaster death toll to 10.
Record-breaking rainfall and early autumn snowfall across Karnali Province have triggered destructive landslides, blocked the vital northern transit corridor in Humla, and pushed the province's monsoon disaster toll to 10 fatalities since mid-July.
Simkot, the district headquarters of Humla situated at an altitude of 2,993 metres, received 114.8 millimetres of rainfall in the 24 hours between September 25 and September 26. As reported by Nepal Watch, Dr. Indira Kandel, head of the Meteorological and Climate Science Office in Surkhet, identified the downpour as the heaviest 24-hour rainfall measured in the district since record-keeping began in 1978.
The deluge surpassed previous peaks of 110 millimetres in 2021 and 98 millimetres in 2015. Out of 14,113 days of monitoring at Simkot, only 3,794 days recorded precipitation above one millimetre, and just one previous day had ever exceeded the 100-millimetre threshold. During the same 24-hour storm window, Birendranagar in Surkhet logged 75.5 millimetres. District authorities confirmed landslides across Humla, Jajarkot, Kalikot, Mugu, Jumla, and Salyan.
Border Route Cut by Floodwaters and Snow
The severe weather crippled vehicular movement along the Simkot–Hilsa highway connecting northern Humla to the border with China. Reporting by Onlinekhabar revealed that flash floods tore through settlements along the corridor, washing away an essential culvert near Kermi village in Namkha Rural Municipality-3. Local residents noted that overflowing streams destroyed agricultural land, swept away standing crops, and wrecked public infrastructure along the Tatopani riverbank.
Simultaneously, high-altitude stretches of the route were buried under heavy snow following a three-day blizzard between September 25 and September 27. Onlinekhabar reported that security personnel were deployed on September 29 to shovel thick snowdrifts off the highway after weather conditions improved. District Police Chief Deputy Superintendent Shankar Khadka confirmed that teams were clearing the road to restore transport links for stranded travellers and northern border communities.
Rising Provincial Casualties
The severe spell compounded months of monsoon devastation across Karnali. Statistics from the Karnali Provincial Police Office, published by Onlinekhabar, document 175 disaster incidents across the province's 10 districts since the start of Shrawan (mid-July). The disasters have claimed 10 lives, injured 31 people, left two missing, and displaced 152 households, while inflicting physical damage on 21 commercial enterprises.
Landslides formed the overwhelming bulk of incidents, accounting for 118 occurrences, alongside 42 floods and 54 bouts of continuous downpours. Jajarkot suffered the highest human loss with four fatalities, Kalikot and Mugu recorded two deaths each, and Salyan and Rukum West each reported one death. Provincial Police spokesperson Santosh Singh Rathore warned that remote mountain terrain continues to obstruct relief and rescue efforts, stressing the critical need for proactive risk reduction and early warning systems over reactive emergency responses.
