torrential downpour — extremely heavy rain concentrated in a small area over a short time, often causing floods and landslides

Compound of 集中 ('concentration') and 豪雨 ('heavy rain, downpour'). Literally 'concentrated heavy rain.'
USAGE:
- Emphasizes that the rain is concentrated in both time and space — falling very hard on a limited area for a short stretch, rather than spreading out over a wide region.
- A frequent term in weather forecasts, news reports, and disaster alerts; often appears in headlines about flash floods (鉄砲水) and landslides (土砂災害).
- The Japan Meteorological Agency (JMA) uses the related term 線状降水帯 ('linear rainband') for a specific pattern that causes repeated 集中豪雨.

- 集中豪雨に見舞われる: to be hit by a torrential downpour
- 集中豪雨による被害: damage caused by a torrential downpour
