Weather officials are forecasting snow in the greater Tokyo area from Monday afternoon through Tuesday. Even a little amount of snow could disrupt traffic in urban areas if it accumulates on roads and railway tracks.
A low-pressure system and a high altitude cold air mass are expected to bring snowfall to wide areas around Tokyo.
Forecasters say snowfall through late Tuesday morning may reach up to 30 centimeters in areas north and west of Tokyo, and one centimeter in central Tokyo. If temperatures fall lower than forecast, Tokyo could see a heavier snowfall.
The Meteorological Agency is warning of transportation disruption and icy roads, as well as strong winds and high waves along Pacific coasts.
