In August 2025, a single hour of extreme rainfall killed hundreds of people in Buner district and reshaped Pakistan’s conversation about climate disasters. A year later, with fresh floods striking the same province and NDMA once again naming Buner among the districts most at risk, the record shows what the government promised, what it delivered, and what still hasn’t been fixed.

What Is a Cloudburst?

Cloudburst means a sudden, heavy localized rain with very heavy rain in a very short time, generally less than an hour. Cloudbursts occur when moist air is pushed up very quickly in the mountains, causing towering clouds to develop and carry a huge amount of water vapour until the cloud eventually has so much water that it releases it all at once, meteorologists said. The danger is heightened in steep mountain valleys as there is little flat land to catch or slow the water, allowing a cloudburst to quickly become a wall of water and debris, with little time for residents to respond. Cloudbursts are extremely difficult to predict precisely as they are localized and develop very rapidly. Weather departments can alert the public to large-scale weather patterns conducive to heavy rainfall (humidity, wind direction, monsoon activity), but currently no forecasting system anywhere in the world can predict exactly which valley or village will receive the rain, and when. This discrepancy between wide-area notifications and localized life-saving advice is at the heart of what occurred in Buner.

August 15, 2025: The Night Buner Changed

Buner is a mountainous District in Khyber Pakhtunkhwa (KP), approximately 100 kilometres due north-west of Islamabad, and is characterized by narrow valleys, steep slopes and streams which flow rapidly during monsoons. This torrential rain fell on the district for approximately an hour, with some estimates putting the amount over 150 millimetres per hour on the evening of August 15, 2025. Having no place to disperse, the water rushed down the hillsides as a force of destruction, sweeping through the villages along the riverbanks, and washing into villages with mud, rocks, and fallen trees. 

The flooding occurred in a few villages, such as Pir Baba, Qadar Nagar, Beshonai and Malik Pura, where the village of Beshonai (with over 80 households) was left in ruins, having had its houses swept away by flash floods in a matter of moments. One instance was reported in which a family had just celebrated a wedding in Qadar Nagar when the floods struck, killing 24 people. There was no warning before the water came, according to survivors and elders there, but via the usual means: through the mosque speakers. Later, the government officials stated this was a sudden and intense rainfall, so intense that they could not give warnings, but that it had been the Buner district (not any particular village) that had been marked as vulnerable in advance. 

Rescue and recovery efforts continued for days. About 2,000 rescuers, army troops and sniffer dogs were sifting through the rubble for the victims and bodies, while landslides and damaged roads and phone lines hindered the efforts. Another provincial government helicopter was also operated in the relief effort and crashed, killing all on board during the crisis.

In the first two weeks, casualty figures fluctuated daily (this is to be expected in such a disaster), but every count referred to Buner as the worst-hit district by a factor of tens. Provincial Disaster Management Authority (PDMA) situation reports put Buner’s death toll at 208 within the first 48 hours, rising past 220 by August 18 as more bodies were pulled from the wreckage.
