A forest fire threatened the village of Weigeng in Yuxi, Yunnan province. Upon receiving the mission, 145 firefighters from the Pu'er Forest Fire Brigade quickly arrived on the scene.

After surveying the surrounding area, they found that although the fire line was less than 500 metres from the village. The blaze was relatively weak and suitable for suppression, as it was a downhill fire with wind speeds of 4 to 5 on the Beaufort scale.

However, just as the team was preparing to start their firefighting work, the wind suddenly changed direction and the fire quickly intensified. The wind speed increased to above 8 on the Beaufort scale, and the downhill fire became an uphill fire, which spread to the mountaintop.

Due to the preheating phase, the fire quickly escalated into a rare explosive burning situation, with flames reaching over 200 metres high and rapidly approaching the Pu'er Forest Fire Brigade.

Liu Dongjun, the political commissar of the Pu'er brigade, explained that the accumulated humus in the valley is much thicker than usual and the dry conditions are severe, combined with the high temperature in recent days, which created a rare and extreme danger beyond their conventional recognition.

The explosion occurred suddenly, and the fire burned from the bottom of the valley to the mountaintop, a distance of about 1 kilometre in less than two minutes. In the critical moment, the firefighters immediately ordered an evacuation. The team quickly assembled and moved to the central open space, seeking cover to resist the high-temperature radiation caused by the explosion.

After scientific command and emergency response, all firefighters were able to narrowly escape the danger. The fire gradually subsided after 10 minutes of explosive burning, and firefighters successfully extinguished the fire that threatened Weigeng Village.

4月13日，云南玉溪围埂村受到森林山火威胁。普洱森林消防145名指战员，在接到任务后，迅速赶达现场。经过对周边火场勘察发现，虽然火线距离围埂村已不足500米，但火势相对较弱，火势为下山火，风力4到5级，适合扑打。
然而，正当队伍准备展开灭火工作时，火场风势突变，火势发展迅猛，风力增至8级以上，由原来的下山火，经过跳火转变为上山火，蔓延到山顶以后，由于前期的预热，形成了爆燃（轰燃），火焰高度达到200米以上，迅速向普洱市森林消防支队袭来。
云南森林消防总队普洱支队政委刘东君介绍：“由于它是个沟谷地带，常年积累的腐殖层比一般的腐殖层要厚很多，干旱情况非常严重，加之这两天的气温又非常高，在风力增大的情况下，形成了一种极为罕见剧燃、爆燃的情况，突破我们常规认知的一个险情。”
爆燃突然发生，火势从山谷底部燃烧到山顶位置，约一公里的距离仅仅用了不到两分钟时间。
云南省普洱市森林消防支队景谷中队副中队长夏招锋：感觉到热浪在不停地急速升温，当时感觉背部有一股强烈的炙烤感，体感温度有七八十度的感觉。
火借风势，风助火威，瞬间黄土漫天，飞沙走石。危急时刻，指战员立即下达避险命令。队伍迅速集结向空地中央转移，并寻找掩体，以此来抵挡爆燃引发的高温辐射。
下午4时许通过科学指挥，全体消防员紧急应对，成功避险。在爆燃持续了10分钟后，火势渐小，消防员们成功扑灭了威胁围埂村的火情。
