Translation guide
A rainstorm is a storm with heavy rain. In Japanese, the most common and natural way to express this is 暴風雨 (bōfūu), which specifically means a rainstorm with strong winds. For everyday heavy rain without strong winds, 大雨 (ōame) is more common. Learners should note that directly translating 'rainstorm' as 雨の嵐 is unnatural.

Do not translate 'rainstorm' as 雨の嵐 (ame no arashi). This is not a natural Japanese expression. Use 暴風雨 or 大雨 depending on the context.
暴風雨 (bōfūu) specifically includes strong winds, while 大雨 (ōame) simply means heavy rain. Use 暴風雨 when wind is a significant factor, and 大雨 for general heavy rain.
The forecast says heavy rain today.
