Tomorrow, the 16th, a low pressure system and front will approach from the west, and the weather will be downhill. On the 17th, the weather is expected to be rainy and stormy across the country. By the 18th, cold air as cold as midwinter will flow into the skies over western Japan, so there is a risk of snow even in flat areas. Please pay attention to the latest weather information.
Tomorrow, the 16th, the weather will be downhill from the west, and the wind will increase in the afternoon.
Tomorrow, the 16th, the weather will be downhill as a low pressure system and front approach from the west.
There will be rain and thunderstorms in Kyushu from around noon, and in Chugoku and Shikoku at night, with extremely heavy rainfall in the form of waterfalls in some areas.
Sunshine will reach the Kinki, Tokai, Kanto, and Hokuriku regions mainly in the morning, but clouds will gradually increase. It will rain in places during the night, so if you will be returning late, please bring rain gear just in case.
Tohoku and Hokkaido will be sunny throughout the day, but there will be some places where it will rain at night.
The wind from the south is likely to gradually become stronger in the afternoon. If you are driving, please be careful not to be swept away by crosswinds.
Tomorrow is the 17th: rough weather with heavier rain mainly on the Pacific side
On the 17th (Friday), a low pressure system is expected to rapidly develop over the Sea of Japan and a front will pass near Honshu. Another low pressure system with a front will pass along the southern coast of Honshu.
Rain and wind are increasing across the country, and the weather is likely to be rough.
As moist air that forms rain clouds flows toward low pressure systems and fronts, rain clouds and thunder clouds will develop mainly on the Pacific side. Please be careful of flooding of low-lying areas, rising river levels, landslides, severe gusts of wind such as lightning and tornadoes, and hail.
Rain will peak in the early morning in Chugoku and Shikoku, early in the morning in Kinki, morning in Tokai and Hokuriku, morning to noon in Kanto-Koshin, midday to evening in Tohoku, and night in Hokkaido. In the Kanto-Koshin region, the peak of rain coincides with the rush hours for commuting to work and school, so be sure to allow plenty of time.
What is very heavy rain?
Very heavy rain refers to rain with an hourly rainfall of more than 50 mm and less than 80 mm. This is an image of rain falling like a waterfall and continuing to fall. Also, umbrellas are completely useless, and about half of the people sleeping inside a wooden house notice the rain. Driving outside is dangerous because the water is spraying all over the place, making the area whitish and reducing visibility.
In addition, 50 mm of rain per hour means that if the rainwater does not flow to another place and accumulates, the rain that falls will be 50 mm high. If 50mm of rain falls on 1 square meter in an hour, the amount of rain will be 50 liters. For example, the area of an open umbrella is approximately 1 square meter, so if you hold the umbrella for an hour, the amount of rain that is equivalent to 50 milk cartons will hit the umbrella.
However, in reality, when rainwater from the surrounding area collects, it can accumulate in excess of the amount of rain that fell at that spot. In areas where extremely heavy rain is expected (in areas where extremely heavy rain has fallen), please be careful of landslides, flooding of low-lying areas, and rising/flooding of rivers.
There is a risk of snowfall even in the flatlands of western Japan. Be careful of the impact on traffic.
From the night of the 17th, cold air as low as -6 degrees Celsius or lower, comparable to midwinter temperatures, will flow approximately 1,500 meters above western Japan.
In the Chugoku region, snow is expected to fall mainly in mountainous areas from the night of the 17th to the 18th, and snow may accumulate even in flat areas. Please be aware of the effects of snow and frozen roads on traffic.
In addition, as the winter-like atmospheric pressure pattern strengthens near Japan, there is a risk of strong winds and stormy weather from Hokkaido to the San’in area. Transportation may be affected, so please pay attention to the latest weather and traffic information.
