Unseasonal "yellow sand" flying. Be careful after tomorrow's rain! [Yellow sand forecast]

2026/01/14 13:32

Today, the 14th (Wednesday), a winter-like atmospheric pressure pattern continues in northern Japan.

Although snow and rain continues on the Sea of Japan side of northern Japan and Hokuriku,
western Japan, eastern Japan and the Pacific side of northern Japan are covered by high pressure and are sunny in many places.



A low pressure system accompanied by a
front is expected to advance into the Sea of Japan and pass over the Japanese archipelago through the night.

In the afternoon, rain and snow will begin to fall from areas on the Sea of Japan side, and
winds will become stronger.



There is yellow sand waiting behind this low pressure system,
Looking at the forecast for yellow dust at 9 am on the 16th (Friday) the next day,
it is expected to fly widely from Kyushu to the southern part of Tohoku.

It is expected that it will continue flying from western to eastern Japan until around the 17th (Saturday).

It may be tempting to wash your clothes or car after the rain, but please be careful as yellow sand may stick to your laundry or car.

If you have a respiratory illness, please take precautions such as wearing a mask.

A complete change from the winter storm; sunny weather similar to March; caution against melting snow; warning of strong winds, blizzard and high waves until tomorrow; winter-like atmospheric pressure pattern after passing of low pressure system

2026/01/13 12:20

During the three-day holiday period, the winter shogun invaded and brought winter storms to various places.
Today, the 13th (Tuesday) after the 3-day holiday, a low-pressure system in the Sea of Japan will rapidly develop, passing near Hokkaido and heading into the Sea of Okhotsk, and a cold front will pass from western Japan to northern Japan.
As a result, there are expected to be heavy storms and heavy storms in places along the Japan Sea side of eastern and northern Japan until tomorrow the 14th (Wednesday).



Also, in eastern and northern Japan today, the 13th (Tuesday), atmospheric conditions will be extremely unstable in some places due to the influence of warm and humid air heading towards the low pressure front.
Temperatures will be similar to March in some places, and even on the Sea of Japan side of Hokuriku and southern Tohoku, many coastal areas are expected to experience rain instead of snow.
As the snow continues to melt, please be careful of deteriorating road conditions, falling snow from roofs, and avalanches in mountain areas.

After the low pressure system passes, we will once again have a winter-like pressure pattern.
The cold air in the upper atmosphere is expected to move southward to western Japan once again.
The snow will intensify, especially in northern Japan, causing blizzards in some places.
Please be careful where you step, as new snow may accumulate on top of melted snow, worsening road conditions.



In eastern and northern Japan, extremely strong winds are expected to blow, leading to strong winds and heavy snow in some places tomorrow, Wednesday the 14th.
The maximum instantaneous wind speed expected through tomorrow the 14th (Wednesday) is 35 m/s in Hokuriku and 30 m/s in the Tohoku region.
On the Sea of Japan side of eastern and northern Japan, there will be heavy rain in some places until tomorrow the 14th (Wednesday).
The expected wave height through tomorrow the 14th (Wednesday) is 6m in Hokuriku and Tohoku.



On the Sea of Japan side of eastern and northern Japan, please be careful of strong winds, heavy snow, and high waves until tomorrow the 14th (Wednesday).
Also, in eastern and northern Japan, please be careful of strong gusts of wind such as lightning and tornadoes today, the 13th (Tuesday).

Rapidly developing low pressure system - Beware of strong winds, heavy snowfall, and high waves from the Sea of Japan side of northern Japan to the Hokuriku region

2026/01/13 07:38

Today, the 13th (Tuesday), a low pressure system accompanied by a front is moving through the Sea of Japan, and is expected to develop rapidly in the future.
On the Sea of Japan side, this low pressure system will cause very strong winds, and it is expected that there will be strong winds at sea. Additionally, a cold front extending from the center of the cyclone will pass from western Japan to northern Japan, making atmospheric conditions extremely unstable in some places.



As cold air moves northward and warm air from the south tends to enter, many places in Hokuriku and Tohoku will experience rain instead of snow during the day. In inland areas and along the mountains of northern Japan, there are likely to be places with wet snow. As snow melts rapidly in areas with heavy snowfall, please be careful of avalanches and falling snow from roofs.



Also, extremely strong winds will blow from the Sea of Japan side of northern Japan to Hokuriku, and the weather is likely to be rough. At sea, there are swells and there is a risk of becoming a big rock.




Tonight, the area around Honshu will have a winter-like atmospheric pressure pattern, and cold air in the upper atmosphere will move southward. From tonight to tomorrow, rain will change to snow in many places from the Sea of Japan side of northern Japan to Hokuriku. In northern Japan, it is likely that there will be a blizzard in some places due to the effects of a rapidly developing low pressure system. From the Sea of Japan side of northern Japan to the Hokuriku region, please be on guard for strong winds and heavy snowfall through the 14th, as well as high waves accompanied by swells at sea.

Tomorrow, the 13th (Tuesday), there will be a lot of rain on the Sea of Japan side. The snow will melt due to unseasonably warm weather.

2026/01/12 20:54

As of 7 p.m. today, Monday the 12th, snow is falling in some parts of Honshu on the Sea of Japan side from northern Japan to Hokuriku.



It snowed this morning on the flatlands of the Tokai region, with 1cm of snowfall observed in Nagoya City and 11cm in Gifu City, the first snowfall of the season.
Although the peak of snowfall has already passed, there are many places around Tohoku, Kanto-Koshin, and Hokuriku, mainly along the mountains, with more than 100 centimeters of snow.



The winter-like pressure pattern near Honshu is gradually loosening, and a low pressure system is expected to pass through the Sea of Japan tomorrow. Warm air from the south toward the center of the low pressure system tends to enter, and temperatures in many places will be similar to those from February to March. The predicted maximum temperature for tomorrow, the 13th (Monday) is expected to be 2c in Sapporo (similar to late February) and 6c in Akita (similar to early March), so the severe cold is expected to ease. On the Pacific side, temperatures in some places are expected to be around the time cherry blossoms bloom, with temperatures expected to reach 15 degrees Celsius in Tokyo (like late March) and 14 degrees Celsius in Osaka (like mid-March), making it unseasonably warm.



However, in places where snowfall increased during the three-day holiday period, it is likely that snow will melt further due to rain. The Sea of Japan coast from southern Tohoku to Hokuriku and northern Kyushu is expected to experience rain instead of snow in many places, with localized thunderstorms.
There may be places in Hokkaido and northern Tohoku that will experience wet snow. In northern Japan, winds are expected to become stronger due to the developing low pressure system, and blowing snow is expected to occur in some places.

On tomorrow, the 13th (Tuesday), which marks the end of the three-day weekend, please be careful of deteriorating road conditions due to melting snow, snow falling from roofs, and avalanches.
Aircraft will be dry on the sunny Pacific side, so please be careful when handling fire.

Although the Sea of ??Japan side has passed its peak, we continue to be on alert for blizzards, etc.

2026/01/12 06:55

The area around Japan has a strong winter-like atmospheric pressure pattern, but it is gradually loosening from the west.
In northern and eastern Japan, very strong winds are blowing, accompanied by snow, and there are places where the sea is swamped.
Also, there are places on the Sea of Japan side of northern and eastern Japan where heavy snow is falling.

As of 6:00, heavy snow warnings have been announced in Tochigi, Gunma, Gifu, and Aichi prefectures, and blizzard warnings have been announced in Niigata prefecture and the Soya, Rumoi, and Ishikari regions of Hokkaido.

Although the peak of wind and snow is passing, it is expected that extremely strong winds will continue to blow in northern and eastern Japan today, the 12th, causing heavy snowfall in some places.
