GLOF Alert in Pakistan: Glacial Flood Risk Has Risen in Gilgit-Baltistan and KP — Here’s What Travelers and Locals Need to Know
A Glacial Lake Outburst Flood (GLOF) alert is in effect for northern Pakistan as rising temperatures accelerate snowmelt and increase water levels in glacial rivers and lakes. Gilgit-Baltistan and parts of Khyber Pakhtunkhwa are the most exposed, with sudden outburst floods, flash floods, and landslides now a real risk over the next 48 to 72 hours. Here is the official warning, the areas on watch, and what to do if you are in a high-risk zone.
The alert was issued by the Pakistan Meteorological Department on Saturday after a sharp rise in temperatures across the high-altitude catchments of GB and upper KP. Sudden drainage from glacial lakes — a normal seasonal phenomenon, but one that has been getting more frequent and more destructive in recent years — is now the most immediate natural hazard facing the country’s north.
What is a GLOF, and why now
A Glacial Lake Outburst Flood is what happens when a dam of ice or moraine holding a glacial lake suddenly fails. The water rushes downstream in minutes, picking up rocks, mud, and debris, and turns normally quiet streams into fast-moving walls of water. The triggers are usually a combination of sustained warm temperatures, rainfall, ice calving, or an internal ice-dam collapse.
The 2026 alert comes after a week of unusually warm weather in the Karakoram and Hindu Kush ranges, with daytime temperatures several degrees above the seasonal average. That heat accelerates snowmelt on the higher peaks and feeds water into the glacial lakes that sit below the snow line. Once a lake overtops or breaks its natural dam, the wave downstream can reach communities within minutes.
Areas on watch
| Region | Risk level | What to expect |
|---|---|---|
| Gilgit-Baltistan (Hunza, Skardu, Gilgit, Ghizer, Shigar, Kharmang) | High | Outburst floods in tributary streams; flash floods in nullahs; landslides on mountain roads |
| Upper KP (Chitral, Swat, Kohistan, Mansehra, Shangla, Buner) | High | Flash floods in mountain streams; landslides on Karakoram Highway and Lowari Top |
| Azad Jammu and Kashmir (Neelum, Jhelum valley, Leepa) | Moderate | Rising river levels; localised flash floods in streams |
| Murree, Galiyat, northern Punjab hill tracts | Moderate | Flash floods in seasonal nullahs; landslides on hillside roads |
What residents and travelers should do now
- Avoid overnight stays near glacial streams. Most GLOFs happen overnight or in the early morning, when colder water temperatures and reduced visibility make the wave hard to spot in time.
- Do not camp on riverbanks, alluvial fans, or in the direct line of any stream that drains a glacier. These are the first areas flooded in an outburst.
- Watch for the warning signs. A sudden drop in water flow downstream of a glacial lake is often the first sign of an upstream outburst — the lake is draining, and the wave will arrive within minutes to hours. If you see this, move immediately to higher ground.
- Stay off the Karakoram Highway and Lowari Top after dark. Landslides triggered by the same conditions have already closed these roads in previous years.
- Keep your phone charged and your CNIC accessible. Rescue operations rely on the local rescue service, the Pakistan Army, and the GB Disaster Management Authority. Identification is needed for emergency travel permits.
- Move valuables and documents to higher ground in your home. Traditional houses along riverbanks in Hunza, Skardu, and the lower Indus catchments have flooded multiple times in recent decades.
- Listen to local FM radio and PDMA alerts. The Pakistan Disaster Management Authority and the GB Disaster Management Authority run regular updates on FM radio and WhatsApp channels during the GLOF season.
If you live within two kilometres of any river that drains a glacier, you are in the immediate flood zone of a potential outburst. Treat every abnormal drop in water level as the first warning, not the last.

How the alert is being managed
The Pakistan Meteorological Department has activated its high-altitude monitoring stations in GB and upper KP, including automatic water-level sensors on the major glacial lakes. The PMD issues GLOF warnings through a combination of satellite imagery, ground sensors, and partner data from the International Centre for Integrated Mountain Development (ICIMOD). Warnings go out via the PDMA, the GB Disaster Management Authority, the KP Provincial Disaster Management Authority, and the National Disaster Management Authority (NDMA).
Rescue assets are pre-positioned in Gilgit, Skardu, Chitral, and Mansehra. The Pakistan Army’s Special Communication Organisation (SCO) maintains emergency helplines in the northern areas, and the district administrations have evacuation plans for the most exposed villages. Tourists and trekkers in the Karakoram and Hindu Kush regions are advised to register with their local hotel or the local tourist information centre.
Why GLOFs are getting more frequent in Pakistan
Pakistan is home to more than 7,000 glacial lakes, the largest concentration outside the polar regions. Of those, around 33 are classified as potentially dangerous and are monitored closely. The 2022 floods, the 2023 Hassanabad disaster in Hunza, and the 2024 Shigar valley flooding are all part of a trend driven by warmer summers, longer melt seasons, and more intense rainfall in the high-altitude catchments. The 2026 alert is consistent with that pattern, and the PMD expects more such alerts in late August and early September as the seasonal melt peaks.
What to do if you are caught in a GLOF
- Move immediately to higher ground — never try to outrun the wave downstream.
- Stay away from bridges, riverbanks, and the foot of any slope.
- If you are in a vehicle, abandon it and climb. Vehicles are routinely swept away.
- If you are indoors on a lower floor, move to the roof or upper floors.
- Do not return to retrieve belongings — the secondary wave is often larger than the first.
- Once safe, contact the GB Disaster Management Authority helpline (see below) or the nearest army checkpoint.

Frequently asked questions
What is a GLOF?
A Glacial Lake Outburst Flood — a sudden release of water from a glacial lake when its natural ice or moraine dam fails. The wave can reach downstream communities within minutes.
Which areas of Pakistan are at risk right now?
Gilgit-Baltistan (Hunza, Skardu, Gilgit, Ghizer, Shigar, Kharmang) and upper KP (Chitral, Swat, Kohistan, Mansehra) are the most exposed. AJK and the northern Punjab hill tracts are at moderate risk.
How long will the GLOF alert last?
The PMD’s high-altitude monitoring is currently in active alert mode for the next 48 to 72 hours, with the seasonal peak expected to last through late August and into early September.
Is it safe to travel to Gilgit-Baltistan right now?
Travel is possible but with precautions. Avoid the Karakoram Highway after dark, register with your hotel or local tourist information centre, and stay away from glacial streams and riverbanks. Trekking and overnight camping near glaciers is strongly discouraged.
What is the helpline for a GLOF emergency?
GB Disaster Management Authority: 05811-920400. KP PDMA: 091-9213845. NDMA national helpline: 051-9205037. For general emergencies, dial 1122.
Are Pakistan’s GLOFs getting worse?
Yes. The 2022 mega-flood, the 2023 Hassanabad disaster, and the 2024 Shigar flooding are all part of a warming-driven trend. Pakistan is home to more than 7,000 glacial lakes, of which around 33 are classified as potentially dangerous and actively monitored.
What is the first warning sign of a GLOF?
A sudden, abnormal drop in water flow downstream of a glacial lake. This usually means the lake is draining, and a large wave is on its way. Move to higher ground immediately.
