Continuing from today, the 12th (Wednesday) and yesterday, the 11th (Tuesday), active rain clouds associated with a front are passing through the Nansei Islands, and the rain is locally increasing. We need to be on guard against heavy rain until tomorrow the 13th (Thursday), when Typhoon No. 26 approaches.



As of 3:00 pm today, Wednesday the 12th, Typhoon No. 26 is slowly moving east-northeast through the Bashi Strait with strong winds.
From now on, Typhoon No. 26 will move northeast near the Bashi Strait, and will move southwest of Yonaguni Island at 3:00 a.m. on the 13th (Thursday) tomorrow.
It is expected to turn into an extratropical cyclone north-northwest of Miyakojima at 3pm on Thursday the 13th.
In Okinawa, there will be a large pressure gradient between the typhoon and the high pressure system.
Also, due to the influence of warm and humid air flowing in from the front and around the typhoon, extremely unstable atmospheric conditions are expected to continue into tomorrow, the 13th (Thursday).

Although the landslide alert has been lifted for the main island of Okinawa, the ground is loose in some places due to the rain that has fallen so far, so please continue to be cautious of landslides and flooding of low-lying areas today, Wednesday the 12th, and be careful of rising river waters.
Depending on the degree of rain cloud development, heavy rain warnings may be issued for a wider area or the warning period may be extended.



In the Sakishima Islands, it is expected that there will be heavy rain in some places until tomorrow, the 13th (Thursday), with an amount of 30mm falling over an hour.
Please be careful of landslides, flooding of low-lying areas, and rising river waters.
Depending on the degree of rain cloud development, there is a risk of heavy rain reaching warning level until tomorrow, the 14th (Friday).

The waters off the coast of Okinawa will continue to be rocky with swells until tomorrow the 13th (Thursday), with waves reaching heights of 5m in some places on the main island of Okinawa.
The Sakishima Islands are expected to experience heavy waves on the Sakishima Islands tomorrow, the 13th (Thursday), exceeding 6m in height.
Please be careful of high waves accompanied by swells.



Very strong winds and strong winds are expected to blow in Okinawa until tomorrow the 13th (Thursday).
The wind is expected to become even stronger tomorrow, the 13th (Thursday), with a maximum instantaneous wind speed of 30m/s.

The aftermath of the Kuroshio meander continues, with sea surface temperatures lower than normal in the waters near the Izu Islands [Ocean summary November 2-8, 2025]

2025/11/12 13:38

The Japan Meteorological Agency and Japan Coast Guard have announced that the Kuroshio Current Meander will end in April 2025 (announced on August 29, 2025).

However, according to JAMSTEC's Kuroshio Watch,
``the aftermath of the Kuroshio Great Meander continues, and meandering is occurring as the
vortex that was torn off from the Kuroshio is absorbed.''



The Kuroshio Current is flowing south of Hachijo Island, and sea surface temperatures near the Izu Islands are lower than normal.

Below is a summary of the ocean from November 2nd to 8th, 2025.



#Pressure distribution and waves
On November 2, a front extending from a low pressure system developing near the Chishima Islands
became stationary from the east of Japan to the waters near Ogasawara.
In the Sea of Okhotsk, waves exceeded 6 meters in height and became a major storm.

On the 3rd, the atmospheric pressure around Japan was high in the west and low in the east,
with wave heights of 4m mainly in the western and central parts of the Sea of Japan, where winds from the north were dominant.

On the 5th and 6th, a low pressure system accompanied by a front moved eastward south of Japan.
On the 6th, wave heights were widely over 3m on the Pacific side, and wave heights of 4m near the Izu Islands.

On the 7th, a low-pressure system developed in the east of Japan and moved northward, and the pressure around Japan became high in the west and low in the east.
On the night of the 7th, wave heights of 7m were observed in the Sea of Okhotsk, and wave heights of 5m were observed off the coast of Sanriku.



#Sea surface temperature
Sea surface temperatures in the Japanese Sea were around normal or slightly higher than normal, and
waters continued to be lower than normal on the continental side of the central Japan Sea.

The East China Sea continued to be at normal levels.
On the Pacific side, the sea area continued to be at normal levels in the south of Japan, but
below normal sea areas expanded from the Izu Islands to the Boso Peninsula, where the Kuroshio current flows off shore.

Off the coast of Sanriku, the area of sea area that is above normal has expanded, and
off the coast of Fukushima, an area that is below normal has expanded.
Off the southeastern coast of Hokkaido, the area of water much lower than normal has expanded.
The Sea of Okhotsk remained at normal levels.

Next week will be the cold of December, the strongest cold air of the season, the impact of Typhoon No. 26 [Weekly Weather]

2025/11/12 12:06

#Weekly Weather Points#
+``Typhoon No. 26'' will approach the Okinawa region tomorrow
+The strongest cold air inflow of the season will occur from the 17th (Monday) to the 18th (Tuesday)
+``Winter storm'' on the Sea of Japan side, with cold northerly winds on the Pacific side



Today, November 12th (Wednesday), there are fewer streaks of clouds associated with the cold air on the Sea of Japan side, and
there are many sunny days in eastern and northern Japan.

Meanwhile, from western Japan to the Nansei Islands, there is cloud cover from the
front and Typhoon No. 26.

Today, rain clouds formed due to the front,
Heavy rain fell on Kumejima in Okinawa Prefecture, with a rainfall of 347.0 mm in the 24 hours until 7 a.m.,
breaking the record for November.



The typhoon is expected to approach the Okinawa region tomorrow, the 13th (Thursday), and the active rain clouds of the typhoon itself are expected to cover the main island of Okinawa and the Amami region.
The expected 24-hour precipitation in the Okinawa region is high,
120 mm
until 6 a.m. tomorrow, Thursday the 13th, and 100 mm
from 6 a.m. tomorrow, Thursday the 13th to 6 a.m. Friday, the 14th.

In the Okinawa region, the ground has loosened in some places due to the rain that has fallen so far, so
continue to be wary of landslides and flooding of low-lying areas, and
take extra precautions against rising river waters.



From the 14th (Friday) to the 15th (Saturday), it will be covered by high pressure moving from the continent
There will be many areas around Honshu that will be sunny.

On the 16th (Sunday), a low pressure system will develop as it approaches northern Japan, and the strongest cold air of the season is expected to flow over Japan from
17th (Monday) to 18th (Tuesday).



Looking at the forecast for cold air from the 16th (Sunday) to the 18th (Tuesday), it is predicted that on the 16th (Sunday), warm air will flow towards a low pressure system, comparable to late October.

However, on the night of the 17th (Monday), cold air that brings snow in the mountains (below 0c at around 1500m) will move south to the Pacific side of western Japan.

Furthermore, on the night of the 18th (Tuesday), cold air (less than -6 degrees Celsius at around 1500m above the ground) that brings snow on the plains is expected to move south to the Hokuriku region, and
to temporarily flow into the Sea of Japan side of western Japan.

When it rains in the mountains of western Japan, it's not rain, but snow in many places, and even on the flatlands of western Japan, there may be places where it snows here and there.

If you drive over mountain roads or passes, it would be a good idea to change to
winter tires by the end of this week.



Looking at the weather for the coming week,
northern Japan is likely to experience frequent snow and rain, and
there is a possibility that it will snow every day in northern Tohoku next week.

Even on the sunny Pacific side, northerly winds are blowing, bringing the cold of winter.
Please take care of your physical condition as the temperature will vary greatly from day to day.

Typhoon No. 26 Okinawa region: Beware of disasters caused by heavy rain

2025/11/12 08:41

As of 6 a.m. today, November 12th (Wednesday), Typhoon No. 26 (Fongwon) is located near the Bashi Strait and is moving slowly north-northeast.
The central pressure is 992hPa.



The typhoon is expected to move northeast near the Bashi Strait on the 12th and approach the Okinawa region on the 13th. Additionally, a front is extending from near Taiwan through the Nansei Islands to the south of Japan, and due to the influence of warm, humid air moving towards the front from around the typhoon, extremely unstable atmospheric conditions will continue in the Okinawa region until the 13th.

-Rain Forecast
The atmospheric conditions in the Okinawa region will be extremely unstable, so there will be places where there will be heavy rain accompanied by thunder.
The predicted 24-hour precipitation from 6:00 on the 12th to 6:00 on the 13th is high in some places,
Okinawa region 120mm
Then, from 6:00 on the 13th to 6:00 on the 14th,
Expected 24-hour precipitation will be high in some places,
Okinawa region 100mm

-Wind forecast
There will be some places in the Okinawa region where there will be very strong winds on the 13th.
Maximum wind speed (maximum instantaneous wind speed) expected on the 12th
Okinawa region 15 meters (25 meters)
Maximum wind speed (maximum instantaneous wind speed) expected on the 13th Wind speed)
Okinawa region 20 meters (30 meters)

-Wave forecast
In the Okinawa region, there will be some places where there will be heavy waves on the 13th.
Wave height expected on the 12th
Okinawa region 4 meters with swell
Wave height expected on the 13th
Okinawa region 6 meters with swell


In the Okinawa region, on the 12th, be alert for landslides and flooding in low-lying areas, and be cautious and alert for rising river levels. On the 13th, be alert for high waves accompanied by swells, and be cautious and alert for strong winds. Also, be cautious of severe gusts such as lightning strikes and tornadoes.

Conditions close to La Nina phenomenon towards the beginning of winter What are the trends in winter in Japan

2025/11/11 13:28

The Japan Meteorological Agency released an El Nino monitoring bulletin on Monday, November 10th.

Currently, conditions appear to be normal, with neither El Nino nor La Nina occurring, but conditions are said to be close to La Nina.
It is expected that La Nina-like conditions will continue through the beginning of winter, but since they will quickly resolve after that, a La Nina phenomenon will not occur, and it is likely that normal conditions will continue through the beginning of spring.



#El Nino/La Nina phenomenon Last month's October live report (from the Japan Meteorological Agency)
It appears to be normal conditions with neither El Nino nor La Nina phenomena occurring, but conditions are close to La Nina.
The difference in sea surface temperature in the El Nino monitoring area in October from the standard value was -0.5c, which was lower than the standard value.
Also, the 5-month moving average used to determine the occurrence of El Nino/La Nina phenomena in August was -0.3c, close to the standard value.
Sea surface temperatures in the equatorial Pacific Ocean were higher than normal in the western part of the country, but lower than normal in the central and eastern regions.
Surface water temperatures in the equatorial Pacific Ocean were higher than normal in the western part of the ocean, but lower than normal in the central and eastern regions, with low temperatures becoming stronger in the eastern part. The easterly winds (trade winds) in the lower atmosphere of the equatorial Pacific region were stronger than normal in the western and central regions.
Convective activity was active near Indonesia, but inactive near the international date line in the equatorial Pacific.
These atmospheric and ocean conditions appear to be normal, with neither El Nino nor La Nina occurring, but they indicate conditions close to La Nina.



#Future outlook (from the Japan Meteorological Agency)
Conditions close to La Nina will continue into the early part of winter.
However, since it will quickly resolve after that, a La Nina phenomenon will not occur, and normal conditions are likely to continue until the beginning of spring.
According to the live report, cold water continues in the central and eastern parts of the equatorial Pacific Ocean.
The coupled atmosphere-ocean model predicts that as trade winds continue to be strong in the equatorial Pacific, sea surface temperatures in the El Nino monitoring area are likely to remain lower than the standard value through the beginning of winter.
After that, however, this state will not last long because the atmosphere-ocean coupling will weaken, and sea surface temperatures are expected to rise rapidly, reaching values close to the standard value at the beginning of spring.
From the above, it is likely that conditions close to La Nina will continue through the beginning of winter, but will not reach the point where La Nina occurs, and normal conditions will continue through the beginning of spring.



#Characteristics of Japan's weather during the La Nina phenomenon
The characteristics of Japan's weather during the La Nina phenomenon during the three months centered on December (November to January) are that the average temperature tends to be average or low in eastern and western Japan.
Precipitation tends to be high on the Sea of Japan side of northern Japan, and low on the Pacific side of eastern Japan and western Japan.
Sunshine hours tend to be high in western Japan, and average or low in Okinawa and Amami.

Typhoon No. 26 takes a sharp turn; warning-level heavy rain is expected until Friday the 14th in Okinawa; strong cold air will flow westward next week [Weekly Weather]

2025/11/11 11:55

As of 9am today, November 11th (Tuesday), Typhoon No. 26 (Fuongwon) is located in the South China Sea and is moving north-northwest at a speed of 15 km/hr.

The central pressure is 980hPa, accompanied by stormy winds.



From now on, it will gradually change its course to the northeast while weakening its strength, and
is expected to approach and land on Taiwan on the afternoon of the 12th (Wednesday) tomorrow.

It is expected to get very close to the Sakishima Islands in Okinawa on the 13th (Thursday), and turn into an extratropical cyclone south of Okinawa by the morning of
14th (Friday).

The typhoon itself is approaching Okinawa's Sakishima Islands while weakening, but
warm and humid air is flowing towards the stationary front near the Nansei Islands,
and there is a risk that heavy rain will continue for a long time even if the typhoon weakens.

There are already heavy rains in some places even before the typhoon approaches,
heavy rain warnings and flood warnings have been announced in the Yaeyama region, including Miyakojima in Okinawa.
Be wary of flooding in low-lying areas, rising water levels and flooding of rivers.

Locally heavy rain will fall in the main island of Okinawa and the Sakishima Islands through tomorrow the 12th (Wednesday),
and depending on the degree of rain cloud development, there is a risk of warning-level heavy rain until around
14th (Friday).
Please be careful of landslides, flooding of low-lying areas, and rising river waters.


[Rain forecast] (24-hour rainfall/in areas where there is a lot of rain)
Today, the 11th (Tuesday) noon to tomorrow 12th (Wednesday) noon
Okinawa main island region 120mm
Sakishima Islands 60mm
From tomorrow 12th (Wednesday) noon to 13th (Thursday) noon
Okinawa main island region 80mm
Sakishima Islands 50mm
.


Very strong and strong winds are expected to blow in the Okinawa region into the 13th (Thursday),
, and swells are expected to occur in coastal waters.

Please be careful of high waves and strong winds.
Please note that depending on the path of the typhoon and the strength of the winds in the East China Sea, there is a risk of strong winds and heavy storms in the Sakishima Islands on the 13th (Thursday).

Also, in the Sakishima Islands and Okinawa main island region,
be careful of strong gusts such as lightning and tornadoes.



After changing from a typhoon to an extratropical cyclone and becoming unclear near Okinawa,
15th (Saturday) will be covered by high pressure and many places will be sunny.

On the 16th (Sunday), a low pressure system accompanied by a front will develop and move towards northern Japan, and
from the 17th (Monday) onwards, a strong winter-type pressure pattern is likely to occur.



The strongest cold air of the season is expected to flow westward from the 17th (Monday) to the 18th (Tuesday).

Snow will fall on the plains over western Japan (below -6c at around 1500m)
Strong cold air will flow in.

It looks like there will be snow in some places in the mountains of western Japan, and it looks like the season will take another big step next week.

Please take care of your physical condition as the temperature difference will be large.

Typhoon No. 26 will pass through Taiwan and reach the Sakishima Islands in the second half of the week; Okinawa should be careful of heavy rain disaster due to long rains

2025/11/11 08:31

As of 6:00 a.m. today, Tuesday, the 11th, Typhoon No. 26 is in the South China Sea and is moving north-northwest at a speed of approximately 15 kilometers per hour, accompanied by strong winds.

#Typhoon No. 26 Tuesday 11th 6:00
==================
Center location South China Sea
Movement North-northwest 15km/h
Central pressure 975 hPa
Maximum wind speed 30 m/s (near the center)
Maximum instantaneous wind speed 45 m/s
==================



Typhoon No. 26 is expected to continue moving northward in the South China Sea, change its course eastward around the 13th, and pass near Taiwan. After that, it is expected to turn into an extratropical cyclone and approach the Sakishima Islands.

A front is expected to form in the Okinawa region, and as moist air from the typhoon flows toward the front, there is a risk of increased frontal activity.
It is likely to rain even before the typhoon approaches, and the effects may last for a long time, so you need to be careful about landslides, flooding of low-lying areas, and rising river waters.

In addition, as the gradient in atmospheric pressure increases between the typhoon and the high pressure system, the winds will become stronger and there is a risk of severe storms on the 13th. Please be careful of high waves and strong winds.

Today's weather on the 11th (Tuesday): Snow on the Sea of ??Japan side of Hokkaido, heavy rain warning for Okinawa, sunshine reaching from Kanto to the west

2025/11/11 06:14

Today, the 11th (Tuesday), winter-like atmospheric pressure patterns will continue mainly in northern Japan. It snows easily, especially on the Sea of Japan side of Hokkaido, so you need to be careful about snowfall. On the other hand, there will be many sunny areas from the Kanto region to the west. Okinawa needs to be careful of heavy rain caused by the front.



Snow and rain will continue on the Japan Sea side from Hokkaido to Tohoku. In Hokkaido, there are places where even flat areas are covered with snow, so be careful of frozen roads. Additionally, the winds are strong in Hokkaido, and there may be some swampy areas along the coast. Please be careful when driving.
It looks like there will be time for sunlight to reach the Pacific side. It will feel cold throughout the day, so please be sure to protect yourself from the cold when you go out.

It will be sunny in many places from Kanto to western Japan. The weather is expected to be relatively pleasant and sunny at around 20 degrees Celsius during the day. It gets cold in the mornings and evenings, so please dress accordingly.

The front is expected to be stagnant in Okinawa. In addition, frontal activity is expected to increase as moist air from the typhoon flows toward the front. Please be careful as rain clouds may develop locally and there is a risk of heavy rain and thunderstorms.

The moon and Jupiter will approach later tonight. Also pay attention to the alignment of the three shining stars. Are you curious about the weather tonight

2025/11/10 12:04

From late night today, the 10th (Monday) to early morning tomorrow, the 11th (Tuesday), the Moon and Jupiter will be seen aligned.
The moon and Jupiter lined up in the sky from late at night yesterday, the 9th (Sunday) to early morning today, the 10th (Monday), but they were probably not visible in many places because they were covered by rain clouds and clouds.
It looks like there will be more places where there will be opportunities for observation tonight.



#Moon and Jupiter approach Also pay attention to the line-up of three shining stars
The sight of the nearly half-moon-shaped Moon, which will reach its waning quarter next Wednesday, and the extremely bright Jupiter, which has a magnitude of -2.4, will catch your eye.
In November, Jupiter is located in the constellation Gemini, and can be seen shining alongside the first-magnitude star "Pollux" and the second-magnitude star "Castor" in the constellation Gemini.
Why don't you enjoy the three stars that are conspicuously arranged, although their brightness is different

#What's the weather like tonight



Tonight, a front will extend south of Okinawa, and intermittent rain is expected in Okinawa.
Amami will also have a lot of clouds and some showers.
It is expected that the atmospheric pressure pattern will continue to be high in the west and low in the east around western and northern Japan.
There will be a lot of clouds from Kinki to Hokkaido on the Sea of Japan side, there will be showers in northern Kinki and Hokuriku, rain on the Sea of Japan side of Tohoku, and rain or snow on the Sea of Japan side of Hokkaido.
Unfortunately, the sky will be in poor condition for observing the moon and Jupiter.
Other areas have few clouds and the chances of observation are high.
However, the temperature is low and cold, so please take proper measures against the cold when observing outside.

Large and strong typhoon No. 26 is expected to head north in the South China Sea and change course to the east. Okinawa should be careful of the impact of the typhoon

2025/11/10 07:42

Large and strong Typhoon No. 26 has passed near the Luzon Island in the Philippines, and as of 6 a.m. today, Monday, the 10th, it is moving west-northwest in the South China Sea.

#Typhoon No. 26 10th (Monday) 6:00 am
===================
Size Large
Strength Strong
Central Location South China Sea
Movement WNW 30km/h
Central Pressure 970h Pa
Maximum wind speed: 35m/s (near the center)
Maximum instantaneous wind speed: 50m/s
===================

Typhoon No. 26 is expected to continue to develop further northward in the South China Sea, and gradually change its course to the east around the 12th. After that, its strength is expected to weaken gradually, but it will approach the Nansei Islands on the 14th. It is expected to turn into a tropical cyclone around the 15th.

In the Nansei Islands, due to the effects of Typhoon No. 26, waves are high with swells on the sea, and there are barges near the Sakishima Islands. Depending on the path of the typhoon, there is a risk of severe damage in the Sakishima Islands until the 11th, and the effects of the waves are expected to continue for some time after that. Please be careful of strong winds and high waves accompanied by swells.

In addition, due to the warm and humid air of Typhoon No. 26 and the moist air circulating around the edge of the high pressure system, the front will remain stationary near Okinawa, and rain is expected to continue into the weekend around the 15th (Saturday). Due to the influence of the front and typhoon, the rain may become stronger, leading to warning-level heavy rain. Please be careful of landslides caused by heavy rain, flooding of low-lying areas, rising water levels and flooding of rivers, and pay attention to typhoon information that will be updated in the future.
