Explanation: 

Detailed explanation-1: -Flash flooding occurs when too much rain falls too fast and too long for the ground to absorb all that water. Louisianans are used to thunderstorms. But if one of those storm cells stall over one area and drops heavy rain for hours, that can lead to dangerous flash flooding that threaten life and property.

Detailed explanation-2: -Note:Flash floods are caused by excessive rainfall occurring in a short period of time.

Detailed explanation-3: -A flash flood occurs when water overflows on or inundates land that is normally dry. Rivers can overflow their banks to cause flooding, and sea waters can be pushed towards land by massive winds, which then causes flooding.
