Morphology

flash + flood

The compound 'flash flood' transparently combines 'flash' (a very short instant) with 'flood' (an overflow of water) to denote a flood that happens suddenly and is usually short-lived. This is a direct compositional pattern and is cross-linguistically common, so a B1 learner who knows both constituents will readily infer the meaning.

Etymology

Flash flood comes from the simple image of a quick flash of water — a sudden burst — that turns roads and valleys into a flood in minutes after heavy rain. That's why the term means a very 'sudden' and short but dangerous flood.
