Q: What are flash floods and why are they dangerous?

<p style=";text-align:left;direction:ltr">Sudden torrents occur when the rain water that has fallen in abundance begins to flow very quickly in the torrent valleys or the torrents that have previously dug, sweeping away everything in its path, even large objects such as vehicles and rocks. It becomes difficult to see the content of the water and the objects that move with it, and large rocks that move quickly with it can collide and strike the human body.<br /><br /> These torrents may move to a stable area, surprising the residents, or these torrents may increase in strength, break out of their streams, and strike other areas that may be inhabited, so it is necessary to follow the torrents streams, and to stay away from valleys, low areas and torrents when there is a state of instability air, or depressions</p>
