Niigata has a cooler climate than most of Japan, with typhoons arriving less often and less directly than in the south, though remnants of storms can still bring heavy rain, and winter here is dominated by snow rather than rain.
Facing the Sea of Japan, the city’s flat, low-lying delta at the mouth of the Shinano River is more shaped by winter snowmelt and Sea-of-Japan-side weather patterns than by typhoons. %s When a typhoon or its remnants does track this far north, the sudden shift from a typically drier pattern means local drainage can be caught off guard, making radar a useful check against the unexpected.
