Starting the week on the 11th (Monday), the weather will be downhill in western Japan, including Kyushu and Shikoku, from the evening onwards due to the influence of a low pressure system off the south coast. It will rain nationwide on the 12th (Tuesday), and there is a risk of locally stronger rain and winds on the Pacific coast. After the southern low-pressure system passes, cold air temporarily enters, and snow falls mainly along the Sea of Japan side of Tohoku and the mountains of Hokuriku. In areas with heavy snowfall, you need to be careful about avalanches.
11th (Monday) Weather is downhill in western Japan with heavy rain at night
Tomorrow, the 11th (Monday), the sky will be covered in high pressure during the day and it will be sunny over a wide area. However, the sunny weather in spring doesn’t last long. The weather is going downhill in western Japan as a low pressure system approaches. It will start raining in Kyushu from the evening, and by night the rain will spread to Chugoku and Shikoku, with heavy rain expected to be strong in some places in southern Kyushu and Shikoku.
12th (Tuesday) Rain and wind intensify on the Pacific side of western and eastern Japan
On Tuesday the 12th, a low pressure front accompanied by a front will move east along the southern coast of Honshu. The so-called “south coast cyclone” sometimes brings snow to areas such as the Kanto region, but this time the cyclone is close to the land and warm air prevails, so it is likely to rain across the country, except for the 2,000-meter-class mountains.
Rain and wind will become stronger in western Japan, mainly in the morning, and in eastern Japan, including the Tokai and Kanto regions, in the afternoon. In the Kanto region, stormy weather is likely to be at its peak around the time of your return trip.
Since low pressure systems move relatively quickly, the period of stormy weather is short, lasting only 3 to 4 hours, but it is important to be aware of the rain and winds that can pick up in local areas. Please be careful of high waves in coastal areas.
12th (Tuesday) night to 13th (Wednesday) morning: Snow on the Sea of Japan side of Tohoku and Hokuriku
The southern coast low pressure system penetrated off the coast of Sanriku and developed on the night of the 12th (Tuesday). Cold air is expected to temporarily intensify behind the low pressure system.
From the night of the 12th (Tuesday) to the morning of the 13th (Wednesday), snow will fall mainly along the Sea of Japan side of Tohoku and the mountains of Hokuriku. Road conditions can change from rain to snow, and in areas with a lot of snow, you need to be careful to avoid avalanches and snow falling from roofs.
Types and characteristics of avalanches
When snow accumulates, avalanches are more likely to occur. An avalanche is a phenomenon in which snow piled up on a slope slides down due to gravity, and there are two types of avalanches.
One is “surface avalanche.” This is a phenomenon where newly fallen snow slides down on top of old snow that has accumulated on the mountain. It tends to occur on steep mountain slopes during the cold winter months of January and February, and often occurs on slopes where snow canopies or snowdrifts have formed.
The other type is “full-thickness avalanche.” This is a phenomenon where all the snow that has piled up on the mountain slides down. This often occurs in early spring when the temperature rises, after rain or due to the Fohn phenomenon, and hard, heavy snow on the slope slides down. Be especially careful on slopes where avalanches have occurred in the past or where there are cracks in the snow.
