Today's 26th (Wednesday) weather: Okinawa and Amami continue to experience stormy weather due to Typhoon No. 18; western and eastern Japan are on alert for intense heat

2026/08/26 07:47

Today, the 26th (Wednesday), strict vigilance is required in areas near the main island of Okinawa and Amami Oshima near Typhoon No. 18 (Soudel), due to strong winds, heavy rain, high waves, and high tides until around noon. The intense heat continues across a wide area west of the Kanto region. Northern Japan needs to be careful of heavy rain and thunderstorms, especially in the southern Tohoku region.



Typhoon No. 18 (Soudel) passed between the main island of Okinawa and Amami Oshima in the early hours of today, the 26th (Wednesday), and continues to enter the storm area. Strict vigilance is required in the area until around noon due to strong winds, heavy rain, high waves with swells, and high tides.
Please refrain from going out and stay indoors in a safe place away from windows. The typhoon will gradually move away in the afternoon, but we still need to be on guard against strong winds, high waves, and heavy rain.





From the Kanto region to western Japan, many places will be covered in high pressure and will be sunny, and the harsh lingering heat will continue. Please continue to take precautions against heatstroke.

On the Pacific side of Kyushu, where moist southeasterly winds from typhoons tend to flow in, clouds will spread, and there will be some places where it will rain temporarily. In other areas, the atmospheric conditions will be unstable in the afternoon as temperatures rise, and people should be careful of showers and thunderstorms.

Meanwhile, the front will remain stationary from the Sea of Japan to the Tohoku region. In the southern Tohoku region and around Niigata Prefecture, clouds are spreading and rain is likely to fall, so be careful of heavy rain and thunderstorms.

[Typhoon information] Strong typhoon No. 18 will be closest to Okinawa main island/Amami in the morning of tomorrow 26th (Wednesday). Be on strict alert against the storm!

2026/08/25 22:32

Strong Typhoon No. 18 was located approximately 30 km southeast of Okinoerabu Island at 9pm today, the 25th, and is believed to be moving west-northwest at a speed of approximately 20 km per hour. The atmospheric pressure at the center is 950hPa, the maximum wind speed near the center is 40m/s, and the maximum instantaneous wind speed is 60m/s.

========================/br
The typhoon is expected to continue moving westward and pass near the main island of Okinawa and Amami from tonight until dawn. In the Okinawa/Amami region, there will be fierce winds and severe storms at sea. In addition, very heavy rain is expected to occur locally, resulting in heavy rainfall.
A linear precipitation band may occur in the Amami region into the morning of tomorrow, Wednesday the 26th. Be extremely cautious of landslides caused by heavy rain, flooding of low-lying areas, rising water levels and flooding of rivers, and be wary of high waves and storm surges.



The winds are expected to become even stronger as the center of the typhoon approaches. From the Amami region to the Okinawa main island region, there is a risk of strong winds reaching a peak of around 40 m/s tonight through early tomorrow morning, and fierce winds are expected to blow that could even cause some houses to collapse. Strict vigilance is required to prevent flying objects, fallen trees, and power outages.

Then, this typhoon will move westward in the East China Sea, decreasing its speed slightly. Because it moves slowly, the effects can last for a long time.
The expected winds, waves, and precipitation through tomorrow, the 26th (Wednesday) are as follows.

[Wind forecast]
Maximum wind speed expected today (maximum instantaneous wind speed)
Amami region 40m/s (60m/s)

If a linear precipitation band occurs, there is a risk that the rainfall will increase locally.

Typhoons are closest during the dark hours of the night. Evacuation during dark hours can be dangerous. If it is difficult to evacuate, try to stay in a high place in your home, away from dangerous places such as slopes or cliffs.

Latest 3-month forecast: Temperatures are high nationwide, and autumn is coming slowly

2026/08/25 17:25

On the 25th (Tuesday), the Japan Meteorological Agency announced the latest 3-month forecast, which shows the weather outlook for the next 3 months.



Due to global warming and the effects of the El Nino phenomenon, the overall atmospheric temperature will be high, especially in the tropical regions.
Also, the El Nino phenomenon is expected to continue into the winter, and sea surface temperatures will be high in the eastern and central parts of the equatorial Pacific, and cumulonimbus clouds will likely occur in this region.
On the other hand, fewer cumulonimbus clouds are expected to occur from the eastern Indian Ocean to the vicinity of Indonesia.

Based on these facts, westerly winds in the upper atmosphere are expected to flow more southward than in normal years, mainly over the Eurasian continent.
Around Japan, it will flow slightly southerly and be weaker than normal.

For the next three months, the area around Japan will likely be covered in warm air. Around November, humid air tends to flow into the Pacific side of northern and eastern Japan and western Japan, making them susceptible to the effects of low pressure.



The temperature trend over the next three months will be higher than normal from northern Japan to western Japan.
September will continue to be a period of severe lingering heat, with many days expected to be extremely hot with temperatures over 35 degrees Celsius, and midsummer days with temperatures over 30 degrees Celsius. Continue to be careful about heatstroke. The average temperature in Okinawa and Amami is likely to be "around normal."

Temperatures are expected to remain higher than average in October and November, and the season is progressing slowly, with autumn likely to arrive later. Even at high altitudes, the leaves may change color at a slower pace.



Precipitation from September to October is expected to be at normal levels nationwide. However, if a typhoon approaches or atmospheric conditions become unstable, there is a possibility that precipitation will exceed normal levels. Please be aware of daily weather changes.
Western Japan tends to have many sunny days, but there are few rainy days, especially on the Pacific side, and water shortages may become more serious. Please be careful about water management and crop management.

In November, northern Japan, the Pacific side of eastern Japan, and western Japan will be susceptible to the effects of humid air and low pressure, and precipitation is expected to be at or above normal. Heavy rain may occur if the autumn rain front stagnates, so be sure to be fully prepared for heavy rain disasters.

Today's 25th (Tuesday) weather: Northern Japan is prone to rain; Okinawa is experiencing rough weather.

2026/08/25 06:17

Today, the 25th (Tuesday), the front is expected to move south across northern Japan. Additionally, as Typhoon No. 18 approaches, Okinawa is expected to experience increasingly rough weather.



It's a day of rain in Hokkaido and northern Tohoku due to fronts and low pressure. Please be careful as there are places where there will be heavy rain with thunderstorms. Please bring rain gear when going out.

It will be sunny in many places from the southern Tohoku region to Kyushu, and today is another day when it is essential to take precautions against heat stroke. It will be dangerously hot, especially in western Japan, exceeding body temperature, and in Kyushu, Kurume, Hita, and Kumamoto are expected to experience extremely hot days with temperatures reaching 40 degrees Celsius. Please be careful of heatstroke by refraining from activities in hot weather, drinking plenty of water and salt, and using air conditioning.
A very hot day is expected in central Tokyo, and it is likely to be the first extremely hot day in 23 days since the 2nd.

As the typhoon approaches, the rain and wind will gradually become stronger in Okinawa, and there is a risk of rough weather. Please be extremely cautious of strong winds and high waves accompanied by swells. Also, please be careful of landslides, flooding of low-lying areas, rising river waters, and storm surges. The typhoon is expected to move at a slower pace, and its effects are likely to continue into tomorrow, the 26th. Please be fully prepared for the typhoon.

Weather for the week: Okinawa is devastated by the approach of Typhoon No. 18; late summer heat is severe in western and eastern Japan

2026/08/24 13:27

From now on, northern Japan will be susceptible to fronts and low pressure systems. Western and eastern Japan will be covered in high pressure on many days, and western Japan in particular is expected to have fewer rainy days.



Typhoon No. 18 is expected to pass near Daito Island with very strong force on the 25th (Tuesday) tomorrow, and will approach Okinawa with strong force around the 26th.
In Okinawa, the wind will gradually become stronger from today, the 24th, and the waves will become higher at sea. There is a risk of strong winds on the 25th and 26th, with strong winds that could cause some houses to collapse. Typhoon No. 18 is expected to gradually slow down as it moves forward, and its effects may linger until around the 28th.
In Okinawa, please be extremely cautious of strong winds, high waves with swells, landslides caused by heavy rain, and flooding of low-lying areas, and be sure to check the latest typhoon information in the future.



On the other hand, the area around Honshu, northern Japan, is susceptible to the effects of low pressure and fronts, and tomorrow, the 25th (Tuesday), the rain will become stronger around noon when the low pressure passes, and localized heavy rain is likely.
In the afternoon, the sky will be unstable, with the possibility of sudden rain and thunderstorms mainly in the inland and mountainous areas from Tohoku to Kinki. Please be aware of sudden changes in the weather.

Around the 27th (Thursday), an autumn rain front will be stationary near Honshu, and the front is expected to bring rain to many places in northern and eastern Japan. Since the northern side of the front will have autumn air, northern Japan will experience short-term weather changes and the heat will gradually ease in some places.



Western and eastern Japan are easily covered by high pressure in the summer, resulting in days of severe lingering heat. In eastern Japan, there will likely be some days when the heat will ease somewhat as the front moves south, but western Japan will continue to be covered in summer high pressure, and in places like Kyushu, it is expected to continue to be around 35 degrees Celsius.
In western Japan, many places, especially in Kyushu, are already receiving less than 20% of normal rainfall, but it will continue to be less susceptible to the effects of humid air, and it is unlikely that the rain will be heavy enough to overcome the low rainfall. You need to be careful not to get heatstroke due to the severe lingering heat, but also be careful about water management and crop management.
