flash flood
This term describes a specific meteorological event characterized by extreme rapidity. A flash flood is defined by its sudden onset, often occurring within minutes or a few hours of intense rainfall, which distinguishes it from general flooding that may rise slowly over several days. It carries a strong connotation of danger and unpredictability, frequently associated with narrow canyons or urban areas with poor drainage.
In technical and journalistic registers, the term is used to distinguish between slow-rising riverine floods and these violent, rapid surges. As a compound noun, it functions as a single semantic unit and follows standard English pluralization rules when referring to multiple occurrences.
