2025/03/31 13:24

Today, the 31st (Monday), cold air below -3 C is flowing into the air above Kanto, Koshin, about 1,500m, which is strong for this time of year.
Also, a low pressure system will occur off the coast of Tokaido by tonight, and it is expected to remain largely stagnant until tomorrow, Tuesday, April 1st.
For this reason, there will be some areas around Kanto, Koshin where cold rain and wet snow will fall until tomorrow, April 1st.



#Snow accumulates late tonight in mountains in Shizuoka Prefecture and southern Kanto region Heavy snow in Yamanashi Prefecture
Snow accumulates in mountains in Shizuoka Prefecture and mountains in the western part of Kanagawa Prefecture, and the snowfall is expected to be 5cm in places with a high 24-hour snowfall.
In Yamanashi Prefecture, there will be areas in the mountains in the central and western parts and in the Fuji Five Lakes in the eastern part of the Fuji peak, and there will be heavy snowfall from the early hours of the 1st to the evening.
24 hours snowfall is expected to be 10cm at a high 24-hour location.

The area around Honshu is covered by mobile high pressure, and today, the 31st, many areas will be exposed to sunlight, mainly in western Japan.
On the other hand, on the Pacific side of eastern Japan, such as the Kanto and Tokai regions, moist air that circumnavigates the edge of high pressure will flow in, making it likely to be a cloudy day. Due to the predominance of clouds, temperatures do not rise much during the day, and temperatures will be around February to March.



By night, a low pressure system is expected to occur off the coast of Tokaido due to the effects of the valley of atmospheric pressure travelling through Honshu and the humid air from the high pressure.
Due to the influence of this low pressure system, there are areas in the Kanto and Tokai regions where cold showers will fall from night, and the cold rain and snow will expand tomorrow morning.



If you look at the forecast for rain and snow tomorrow morning, the 1st (Tuesday), you will see that sleet and snow are predicted, mainly from southern Tohoku to the inland areas of the Kanto-Koshin region and along the mountains. You need to be careful about snow accumulation caused by wet snow and the condition of the road surface. Cold rain is expected in the plains of southern Kanto, and the highest daytime temperature in central Tokyo is expected to be 8 C, making it colder than 10 C.

/April is likely to start in southern Tohoku, Kanto, Koshin, Hokuriku, and Tokai, as cold as midwinter. Please be careful not to disrupt your health.
