27 mm of rain can be considered a substantial amount depending on the context.

In contrast, for regions accustomed to heavy rainfall, it might be seen as moderate. The impact also greatly depends on the duration over which this rain falls; a short, heavy downpour might cause more immediate issues than a longer, steady rain.
