Detailed Report
A Glof refers to the sudden release of water and debris from a glacial lake, leading to the loss of lives, property, and livelihoods in mountain communities. Over 7.1 million people in GB and KP are vulnerable to the phenomenon, according to the Ministry of Climate Change.
In its statement, issued on Saturday, the Met Office said that a moderate westerly wave is expected to enter the upper regions of Pakistan from Sunday.
“During this period, widespread rain, wind thunderstorms, and isolated heavy falls, are anticipated across Gilgit-Baltistan and Khyber Pakhtunkhwa,” the alert said.
According to the PMD, the sudden increase in temperatures followed by widespread precipitation “significantly elevates” the risk of Glofs, flow of debris, and flash flooding in vulnerable areas, particularly in Hoper, Ghulkin, Shishper, Yasin, Phander, Badswat, lower Hunza, Nagar, Ghanche, Shigar, Swat, upper Chitral, Dir and Astore.
Residents in glaciated valleys are advised to avoid proximity to riverbanks and stream beds during rainfall and secure livestock and essentials in higher safe grounds. They were also asked to disseminate the alert via SMS and social media.
The PMD alert also advised residents to monitor local nullahs for sudden changes in water colour, indicating muddiness, or unusual sounds that could indicate grinding rocks.
It directed them to coordinate closely with Community-Based Disaster Risk Management Committees (CBDRMCs). It further directed the disaster management authorities to ensure round-the-clock alertness and maintain active communication links with technical focal persons in remote valleys.
The PMD advised all concerned parties to “remain alert and take necessary measures to avoid any untoward situation”.
Pakistan is home to over 13,032 glaciers, the largest reservoir of glaciers outside of the polar regions. However, experts have warned that about 10,000 glaciers in Chitral and GB have been reported to be receding due to climate change–induced temperature rise.
In February, the National Emergencies Operation Centre (NEOC) of NDMA issued an advisory regarding potential Glof risks from March to September 2026, citing anticipated rising temperatures, changing weather patterns, and possible early heatwave conditions in northern Pakistan.
Rapidly melting glaciers, Glofs and cloudburst incidents severely affected residents of GB last summer. Experts said residents of the region, particularly those living downstream of rivers and glacial lakes, faced serious threats this summer.
