Tohoku region, Hokuriku region: Be careful and be alert to disasters caused by heavy rain

2025/11/03 08:41

There is a low pressure system in the central Japan Sea and east of Japan, moving eastward and northeastward, respectively. Meanwhile, high pressure is protruding from the continent.
Currently, rain and thunderstorms are occurring mainly on the Sea of Japan side of Honshu.



On the 3rd, strong cold air for this time of year will flow at an altitude of approximately 5,500 meters, with temperatures below -30 degrees in northern and eastern Japan and below -24 degrees in western Japan. Additionally, a low pressure system is expected to move toward the Tohoku region, and a trough of pressure is expected to pass from western Japan to northern Japan. As a result, atmospheric conditions from northern to western Japan will be extremely unstable due to strong cold air and low pressure in the upper atmosphere.



#Rain Forecast#
There will be heavy rain or strong rain accompanied by thunder in some places on the 3rd in the Tohoku and Hokuriku regions. There are places where the ground has become loose due to heavy rains so far, and the risk of landslides may increase even with little rainfall.
The predicted 24-hour precipitation from 6:00 on the 3rd to 6:00 on the 4th is high in some places:
Tohoku Japan Sea side 40 mm
Niigata Prefecture 100 mm
br Toyama Prefecture 60 mm
Ishikawa Prefecture 60 mm
Fukui Prefecture 60 mm

#Wind forecast#
Maximum expected on the 3rd Wind speed (maximum instantaneous wind speed)
Tohoku Sea of Japan side Sea 18 meters (30 meters) Tohoku Sea of Japan side Land 13 meters (25 meters)

#Disaster prevention matters#
Please be careful of landslides, flooding of low-lying land, and rising river waters on the 3rd in the Tohoku and Hokuriku regions. From northern Japan to western Japan, please be careful of thunderstorms, tornadoes, strong gusts of wind, and short periods of heavy rain for the next 3 days. If there are signs that a cumulonimbus cloud is approaching, please take precautions such as moving inside a building. There is also a risk of hail, so please be careful when managing crops and agricultural facilities.

The Sea of ??Japan side from Tohoku to Hokuriku is experiencing rough weather. Be careful and be cautious of heavy rain and strong winds

2025/11/02 17:42

There are low pressure systems over Hokkaido and the western Sea of Japan, which are moving northeast and east, respectively.
The low pressure system in the Sea of Japan will approach the northeast Sea of Japan side towards the morning of the 3rd, and after that, the pressure will temporarily become high in the west and low in the east, and the gradient of the pressure will become larger.
Also, through the 3rd, strong cold air is expected to flow into the air at an altitude of approximately 5,500 meters, with temperatures below -30 degrees Celsius in northern and eastern Japan, and below -24 degrees Celsius in western Japan.
For this reason, atmospheric conditions from northern Japan to western Japan will be extremely unstable due to strong cold air and low pressure in the upper atmosphere.



If rain clouds develop more than expected in the Tohoku and Hokuriku regions, there is a possibility of warning-level heavy rain.
Also, if the pressure gradient in the sea off the Sea of Japan side of northeastern Japan becomes larger than expected, there is a possibility of warning-level winds from the north.



###Rain Forecast
In the Tohoku and Hokuriku regions, there will be heavy rain or strong rain accompanied by thunder in some places through the 3rd.
There are places where the ground has become loose due to the heavy rains so far, and the risk of landslides may increase even with little rainfall.

The predicted hourly precipitation from the 2nd to the 3rd is 20 mm in some places,
on the Sea of Japan side of Tohoku.

The predicted precipitation for the 24-hour period from 6pm on the 2nd to 6pm on the 3rd is expected to be 60mm in some places,
on the Sea of Japan side of Tohoku.
Hokuriku region 100mm.



###Wind forecast
Maximum wind speed (maximum instantaneous wind speed) expected on the 3rd
Tohoku Sea of Japan side, sea, 18 meters (30 meters).
Tohoku Japan Sea side land 13 meters (25 meters).

###Disaster Prevention Matters
In the Tohoku and Hokuriku regions, please be careful of landslides, flooding of low-lying areas, and rising river waters through the 3rd.
Be careful of thunderstorms, tornadoes, severe gusts of wind, and short periods of heavy rain from northern Japan to western Japan until the 3rd.
If there are signs that a cumulonimbus cloud is approaching, please take precautions such as moving inside a building.
There is also a risk of hail, so please be careful about managing crops and agricultural facilities.

Be careful of sudden thunderstorms on the Sea of ??Japan side of northern Japan and Hokuriku on today, the 2nd (Sunday), the middle day of the three-day holiday.

2025/11/02 08:02

Today, the 2nd (Sunday), the middle day of the three-day holiday, is expected to be sunny in many places from eastern Japan to the Pacific side of western Japan.
On the other hand, in areas along the Sea of Japan from northern Japan to northern Kyushu, atmospheric conditions become unstable due to strong cold air in the upper atmosphere and low pressure moving across the Sea of Japan.

In Hokkaido, the wind will be weaker than the previous day, the 1st (Saturday), but due to the influence of a low pressure system moving through the Sea of Japan, rain will come and go. It looks like it will snow in some places along the mountains.



Be careful of sudden changes in weather, especially in the afternoon, on the Japan Sea side from Tohoku to northern Kyushu.
Looking at the probability of a lightning strike at 3:00 p.m. today, the 2nd (Sunday), there is an area with a particularly high probability of a lightning strike extending from the Sea of Japan side of northeastern Japan to the Hokuriku region. The predicted probability is over 90% in many places, and people need to be careful of short-term sudden rain, thunderstorms, lightning strikes, hail, tornadoes, and other violent gusts.



Additionally, in areas on the Sea of Japan side, westerly winds are expected to strengthen due to the influence of the low pressure system. Please be careful of strong winds and high waves, especially in coastal areas.



From tonight until tomorrow 3rd (Monday), cold air with temperatures below 0c at an altitude of approximately 1500m is expected to move south toward Honshu. Some of the cold air is expected to move south into the skies over the Chugoku Mountains and Shikoku Mountains, and snow may fall in some places in the high altitude mountainous regions of Honshu into the 3rd of tomorrow. If you are planning a leisure trip to the mountains, please be aware of the road conditions.

Typhoon No. 25 (Karmaegi) occurs off the east coast of the Philippines.

If you are planning to travel to Southeast Asia in the future, please pay attention to the latest typhoon information.

Typhoon No. 25 is not expected to have any direct impact on areas near Japan.

#Number of typhoons occurring and landing in 2025
The average number of typhoons that occur in a year is 25.1. In 2025, 25 typhoons have occurred by November 1st.

There were three typhoons that made landfall in 2025: Typhoon No. 5, which made landfall near Cape Erimo in Hokkaido in July, Typhoon No. 12, which made landfall near Hioki City, Kagoshima Prefecture in August, and Typhoon No. 15, which made landfall in Kochi Prefecture in September and re-landed in Wakayama Prefecture. The average number of typhoons that make landfall is 3, and both the number of typhoons that occur and the number of typhoons that make landfall in 2025 will remain at the same level as normal.

The number of typhoons in November was 2.2, making it still a time when typhoons are likely to occur. Please continue to pay attention to the latest typhoon information.

[Typhoon No. 25 to occur] Typhoon egg (tropical cyclone) is developing and heading west. Has it developed into a "strong typhoon" What is the future course

2025/11/01 14:07

Today, November 1, 2025 (Saturday) at 9 a.m., the Japan Meteorological Agency announced that a tropical cyclone in the Caroline Islands is expected to develop into a typhoon within 24 hours.



The next typhoon will be typhoon number 25.

The number of typhoons that occur in a normal year is 25.1,
which is about the same level as a normal year.




After this, the tropical cyclone is expected to advance over the warm ocean,
and move westward while developing.

It is expected to become a typhoon by tomorrow,
after passing through the Philippines, it is expected to intensify into a ``strong typhoon'' in the
South China Sea, accompanied by stormy winds.

Currently, there is no direct impact on Japan, but
in the past, there was a typhoon that came to the Philippines in November and caused heavy damage.

In addition, in the past, typhoons have made landfall in Japan at the end of November, so it is still a time when we cannot let our guard down as the typhoon season is over.

Please continue to pay attention to the latest typhoon information.
