Tomorrow, the 9th (Sunday): Widespread rain; thunderstorms and strong rain and wind in some places; watch out for melting snow in Hokkaido

2025/11/08 12:21

Today, the 8th (Saturday), the area around Honshu is covered in high pressure and the weather is crisp and sunny, making it a perfect day for going out and viewing autumn leaves.
Tomorrow, the 9th (Sunday), rain will fall across the country due to low pressure and fronts.
The rain and wind will be strong in some places, so please take advantage of the sunshine today, the 8th (Saturday).



As of 9 a.m. today, the 8th (Saturday), a front is extending from the continent to the East China Sea.
By tonight, a low pressure system will have formed in the East China Sea above the front, and is expected to move eastward around western and eastern Japan until tomorrow, the 9th (Sunday).
Also, tonight, a front will extend from the Yellow Sea to the northeastern region of China, forming a low-pressure system accompanied by the front, and moving towards the Sea of Okhotsk into tomorrow, the 9th (Sunday).
A cold front extending from a low pressure system is expected to pass through eastern and northern Japan.
Atmospheric conditions will be unstable due to the influence of warm, humid air heading towards low pressure systems and fronts, as well as cold air in the upper atmosphere.
Please be careful of strong rain, thunderstorms, and sideways rain.



Tomorrow, the 9th (Sun), it will rain in many places in western Japan from the morning, and the Tokai and Kanto regions will experience rain on and off.
In the Pacific coast of western and eastern Japan, please be careful of sideways driving rain caused by strong winds.



As the low pressure moves eastward, the area where it will rain is expected to gradually expand.
There will be more places in Hokuriku where it will start raining from around noon.
In northern Japan, rain is expected to start falling from the Sea of Japan side in the afternoon, with some thunderstorms expected.
At night, there will be places on the Pacific side of northern Japan where it will start to rain.



Hokkaido is also expected to experience rain instead of snow as warm, humid air will flow toward the low pressure system moving toward the Sea of Okhotsk.
The currently accumulated snow is expected to melt in many places in the plains by the morning of the 9th (Sunday), but in the mountainous areas, rain will fall where snow remains, so please be careful of deterioration in road conditions due to melting snow.

Large and strong typhoon No. 26 is moving westward off the eastern seaboard of the Philippines. Heavy rain and heavy storms are expected in Okinawa and the Sakishima Islands from the beginning of the week.

2025/11/08 07:26

As of 6 a.m. today, Saturday, August 8, Typhoon No. 26 is moving westward over the eastern seaboard of the Philippines. The central pressure is 965 hPa, the maximum wind speed near the center is 35 m/s, and the maximum instantaneous wind speed is 50 m/s.

Typhoon No. 26 is expected to continue to develop and move westward, becoming extremely strong by the 9th. It is expected to pass over Luzon Island in the Philippines around the 10th, then change its course northward and approach Taiwan around the 13th.



In Okinawa and the Sakishima Islands, waves will gradually become higher as Typhoon No. 26 approaches, and there is a risk of heavy swells from the 10th (Monday) to the 12th of the week. In addition, there is a possibility of warning-level heavy rain, so please pay attention to the latest typhoon information that will be updated in the future.

The current situation is that there is still a great deal of uncertainty regarding the future course. Some predict its path to end in the South China Sea, while others predict it will move eastward over the sea south of Honshu. If Typhoon No. 26 moves eastward, it may affect Honshu as well, so please pay close attention to future typhoon forecasts.

What's the weather like on Saturday and Sunday Tomorrow, the 8th (Saturday) will be a good day for tourists, but rain is expected over a wide area on the 9th (Sunday).

2025/11/07 20:00

Tomorrow, the 8th (Saturday), the area around Honshu is expected to be covered in high pressure. The atmospheric pressure distribution, with high in the west and low in the east, will loosen, and areas of calm and sunny weather will likely spread. However, the weather is expected to turn downhill from the day after tomorrow until the 9th (Sunday).



In Hokkaido, there are places where it will snow until tomorrow morning, and there are likely to be places where snow will accumulate even in flat areas. There is a possibility of increased snowfall along the mountains, so please be careful of road conditions and traffic hazards.
The weather is expected to improve in many places in Hokkaido from around noon.

It will be extremely cold in the mornings around Honshu, with some places inland experiencing temperatures below 10 degrees Celsius. There is a possibility of frost, so please take care of your crops. Also, please do not get sick due to the difference in temperature between morning and afternoon.
The sun will shine through during the day, and the weather will be mild and sunny in many places, making it a perfect day for sightseeing. It might be a good idea to go out to see the autumn leaves. Your laundry will dry well.

However, clouds are expected to gradually spread over western and eastern Japan from the evening. In western Japan, there will be places where it will start raining late at night.



Two low pressure systems accompanied by a front are expected to pass near Honshu the next day (Sunday), causing rain to fall over a wide area from northern to western Japan, with some places experiencing heavier rain. Due to the rain, the temperature rises slowly during the day, making it feel colder.
If you are planning to go out the next day on the 9th (Sunday), be sure to take precautions not only against the rain but also against the cold so that you do not get sick.

Weather for today, the 7th (Friday): Rain to snow in Hokkaido, clear skies and sunshine in eastern and western Japan

2025/11/07 06:28

Today, the 7th (Friday), is the 24th solar term, ``First Winter'', which is the beginning of winter according to the calendar. Due to a winter-like atmospheric pressure pattern centered in northern Japan and cold air flowing into the sky, snow will gradually fall in Hokkaido as per the calendar. On the other hand, many places on the Pacific coast west of the Kanto region are likely to have sunny skies.



In Hokkaido, strong cold air will flow into the sky, so snow will gradually spread through the night. Snow is expected to fall mainly along the mountains until around noon, and snow is expected to fall in the afternoon on flat areas such as the Sea of Japan and Sea of Okhotsk sides. In addition, the wind will become stronger, so you need to be very careful when driving.
The temperature does not rise throughout the day, so please be sure to protect yourself from the cold.

Tohoku will experience changeable skies. Even if it's sunny, there's a chance of rain showers, so be sure to bring a foldable umbrella when you go out.

The sun will shine widely from eastern Japan to western Japan, and the sky will be refreshingly blue. The weather hasn't turned bad, and there doesn't seem to be any problem with drying laundry outside. During the day, the temperature in many places exceeds 20c, making it a pleasant and sunny day. It gets cold in the mornings and evenings, so you need to be careful about the temperature difference.

[1 Month Forecast] Is it unlikely that winter-like atmospheric pressure distribution will occur in the future Will the season move slowly

2025/11/06 16:39

Today, the 6th (Thursday), the Japan Meteorological Agency announced the weather forecast for the next month (November 8th to December 7th) across the country.

The average sea level pressure for the next month is expected to be lower than normal near Siberia, and the Siberian High is weak, so it is predicted that winter-like pressure patterns will not occur near Japan.
The atmospheric pressure in northern, eastern, and western Japan is higher than normal and will likely be covered by a high-pressure system.
In Okinawa and Amami, the atmospheric pressure is lower than normal, and there is expected to be a period at the beginning of the period when it is susceptible to the effects of humid air.
The temperature at an altitude of approximately 1,500 meters is predicted to be higher than normal from western Japan to Okinawa and Amami, as the cold air from the continent is weakly moving southward.



# Weather for the next month (11/8-12/7)
On the Sea of Japan side of northern Japan, there are expected to be fewer cloudy, rainy, or snowy days compared to normal years.
The Pacific side of northern and eastern Japan will have more sunny days than normal.
The Sea of Japan side of eastern and western Japan is normally in the rainy season, but it is expected that there will be fewer cloudy and rainy days compared to normal years.
On the Pacific side of western Japan, the weather changes every few days, but there will be more sunny days than normal.
Okinawa/Amami is expected to have many cloudy and rainy days, similar to normal years.

#Temperatures for the next month (11/8 - 12/7)
As they are likely to be covered by warm air, temperatures will be high in western Japan, Okinawa and Amami, and at or above normal in eastern Japan.
The progress of the seasons seems to be slow.
However, there are more sunny days than normal on the Pacific side, and when the weather clears up, the morning will be colder due to radiation cooling.
The temperature difference between daytime and daytime is expected to increase.
We recommend wearing clothing that allows you to easily adjust your experience, such as something to put on.
Also, the temperature difference between morning and evening and daytime will increase, and the autumn leaves will change color slowly.



#Precipitation for the next month (11/8-12/7)
There are periods when it is easily covered by high pressure and is less affected by cold air. Precipitation over the next month is expected to be low on the Sea of Japan side of eastern and western Japan, and at or below normal on the Sea of Japan side of northern Japan and the Pacific side of eastern and western Japan.
Okinawa/Amami is susceptible to the effects of humid air, especially at the beginning of the season, and heavy precipitation is expected over the next month.

#Sunshine hours for the next month (11/8 to 12/7)
There will be plenty of sunshine on the Pacific side of northern Japan, as well as eastern and western Japan, and it will be at or above normal on the Sea of Japan side of northern Japan.

[Double typhoon in progress] Typhoon No. 26 is predicted to be ``very strong''. Will it affect the Japanese archipelago next week Pay attention to trends

2025/11/06 11:55

Typhoon No. 26 (Fongwon) occurred near the Mariana Islands at 3:00 a.m. today, November 6th (Thursday).

Currently, Typhoon No. 25 (Karmaegi) is moving westward in the South China Sea with "very strong" force,
creating a "double typhoon" in which two typhoons will form in the south of Japan in November.



---------Information on Typhoon No. 25 (Karmaegi)---------
Live coverage at 9am on November 6th
Type Typhoon

Strong wind area of 25 m/s or more Entire area 140 km
Strong wind area of 15 m/s or more South side 440 km North 390 km
-----------------------------------------

Typhoon No. 25 is expected to make landfall in Vietnam tonight, with the central pressure dropping to 935hPa
reaching the peak of its development.

In areas such as Hoi An and the ancient capital of Hue in central Vietnam,
more than 1,000 mm of rain fell in 24 hours due to the damp and cold air in late October, making it a record heavy rain.

In areas where widespread flooding and other major damage has occurred,
the next typhoon will approach with very strong force,
there is a risk of further heavy rain disasters.

After making landfall in Vietnam, the typhoon is expected to weaken rapidly,
to advance to Laos tomorrow, the 7th (Friday), and to become a tropical cyclone in Thailand on the morning of the 8th (Saturday).





---------Information on Typhoon No. 26 (Fuongwon)---------

-----------------------------------------


On the other hand, Typhoon No. 26 will move westward as it continues to intensify, as it will move over warmer seas.

The central pressure is expected to drop to 980hPa on the morning of the 7th (Friday),
with strong winds.

On the 8th (Saturday), it becomes a strong force, and on the 9th (Sunday), it becomes a very strong force, and
There is a high possibility that a "strong" force will approach and land on Luzon Island in the Philippines on the 10th (Monday).




Looking at the weekly weather map, from around the 10th (Monday) to the 11th (Tuesday), Typhoon No. 26 will turn sharply westward and disappear from the weather map, but from around the 12th (Wednesday), it is possible that it will make a U-turn and approach
the Japanese archipelago such as Okinawa.

We need to pay close attention to the future trends of Typhoon No. 26.



Finally, the weekly weather.
Until around the 8th (Saturday), many places will be covered in high pressure and sunny, but
from the 9th (Sunday) to the 10th (Monday), a low pressure system and front will pass through, causing widespread rain.

The weather will temporarily improve on the 11th (Tuesday), but from the 12th (Wednesday) to the 13th (Thursday), there will be rain in many places due to the influence of the low pressure
(possibly a typhoon or a low pressure system that changes from a typhoon) moving along the southern coast of Honshu
and the front.

Next week's weather may change significantly depending on the future trends of typhoons, so
Please continue to pay attention to the latest weather and typhoon information.

[Ocean Summary] A low pressure system is rapidly developing, and a big storm is occurring in the east of Japan. Sea surface temperatures in the Sea of ??Japan are much higher than normal, and the area is shrinking (October 26, 2025 - November 1, 2025)

2025/11/05 15:09

Frequently, low-pressure systems developed as they moved near Japan, resulting in a disaster in the Sea of Okhotsk and a major disaster in the east of Japan.
In the Sea of Japan, areas where sea surface temperatures are much higher than normal have shrunk, and areas where sea surface temperatures are at or near normal have expanded.
Below is a summary of the ocean (October 26, 2025 - November 1, 2025).



#Pressure distribution and waves
On the 26th and 27th, a front extended from south of Okinawa to east of Japan, and a low pressure system moved eastward south of Japan on the front.
In addition, a low pressure system accompanied by a front moved east of Japan, and another low pressure system moved northeast over the northern Sea of Japan.
Waves were high in the waters near Okinawa and from south to east of Japan, and on the 27th, waves were also high in the Sea of Japan and the Sea of Okhotsk. On the 28th and 29th, a developing low pressure system moved eastward through the Sea of Okhotsk, causing waves to become high in the central part of the Sea of Japan, with wave heights exceeding 4 m in the northern Sea of Japan and the Sea of Okhotsk.
From the 28th to the 31st, a front extended from south of Okinawa to east of Japan, and the gradient of atmospheric pressure increased between it and the high pressure system moving near Japan.
It was in the waters near Okinawa on the 29th, and east of Japan on the 30th and 31st.
On the 1st, a low pressure system rapidly developed and moved from the coast of Sanriku to the waters near Chishima, and the wave height became large off the coast of Sanriku, exceeding 6 meters.



#Sea surface temperature
In the Japanese sea area, areas where sea surface temperatures are much higher than normal have shrunk, and areas where sea surface temperatures are around normal have expanded.
On the continental side of the central Japan Sea, sea conditions continued to be lower than normal.
In the East China Sea, the area slightly higher than normal has shrunk and is now near normal.
On the Pacific side, waters slightly higher than normal continued south of Japan.
The waters around the Izu Islands were slightly lower than normal, while off the coast of Sanriku, the waters were significantly higher than normal.
On the other hand, south of the Kuril Islands, the area of sea area that is much lower than normal has expanded.
The Sea of Okhotsk remained at normal levels.
