9 1 Weather in the Debris Flow Disaster Area of Wama Township, Baoshan, Yunnan

From 2nd to 4th, the weather in Longyang District was light to moderate rain, and it turned into thunderstorm on 4th, and the temperature remained between 18 and 27 degrees Celsius. According to the long-term forecast, rainy weather may last until after the 7th, which will add some difficulties to the rescue work.

Landslides are mainly caused by heavy rainfall and debris flow. The local landform type river has deep cutting depth, steep mountain slope and poor stability; From autumn of 2009 to early summer of this year, Yunnan suffered from severe drought. Continuous drought leads to loose cracks in rocks and soil, which reduces its stability. In heavy or continuous rainfall, the probability of sudden collapse, landslide, debris flow and other geological disasters is obviously increased.
