A sudden, brief, and intense rainstorm, often with strong winds.
The weather forecast warned of a rainsquall approaching the coast this afternoon.
Rainsquall → It is formed from "rain" (from Old English *regn*, meaning water droplets falling from the sky) and "squall" (from Middle English *squale*, meaning a sudden, sharp gust of wind). The word "rainsquall" describes a sudden, brief, and intense rainstorm often accompanied by strong winds.
Imagine a sudden burst of 'water droplets' ('rain') being driven by a 'sharp gust of wind' ('squall') — that's what a rainsquall is.
