[Typhoon No. 31] Erratic typhoon—pay close attention to future path forecasts.

2026/10/31 20:27

Very strong Typhoon No. 31 is moving in a north-northeasterly direction in the waters near the Ogasawara Islands.

While the typhoon is expected to shift its course toward the east tomorrow, the 1st, it is forecast to slow down and potentially stall between tomorrow and the 2nd. Thereafter, it will move slowly in a north-northeasterly direction through the 4th; the Ogasawara Islands may remain under the influence of the typhoon for an extended period.



As the typhoon approaches the vicinity of the Ogasawara Islands, please be on alert for high waves. A strong wind advisory is currently in effect. Depending on the typhoon's path, there is a risk of violent winds between the 3rd and the 5th. Furthermore, the rain clouds associated with the typhoon itself may reach the islands between the 4th and the 5th.

Please stay updated on the typhoon's projected path and take steps to evacuate early.

Looking ahead, low- and high-pressure systems are expected to pass alternately near Honshu, leading to weather patterns that shift every few days. In Hokkaido, there will be days when snow falls as cold air from the upper atmosphere moves southward.
Additionally, please keep an eye on the movement of Typhoon No. 31, which is currently tracking south of Japan.



Tomorrow, Sunday the 1st?the first day of November?Hokkaido will see snow due to cold air in the upper atmosphere, with some areas likely to experience snow accumulation. Elsewhere, regions near Honshu will be under the influence of a high-pressure system, leading to mostly sunny conditions during the day. However, low-pressure systems and fronts are approaching from the Sea of ??Japan and the East China Sea; in Northern Japan, the weather may deteriorate late tomorrow night.

The day after tomorrow, the 2nd, a low-pressure system accompanied by a front will pass near Honshu, bringing rain across the country. In some areas, the rain may intensify and be accompanied by thunderstorms, so please exercise caution. In Northern Japan, as cold air moves south, some parts of Hokkaido may see snow, potentially continuing into the 3rd.

On Tuesday the 3rd?Culture Day?the area around Honshu will be covered by a high-pressure system, leading to a widespread improvement in the weather; it should be a good day for going out. While the 4th (Wednesday) is expected to be mostly sunny, around the 5th (Thursday), the influence of low-pressure systems and fronts will likely bring rain to many parts of Northern and Eastern Japan.

To the south of Japan, Typhoon No. 31?a very strong storm?is moving through the waters near the Ogasawara Islands. It is currently moving slowly and is expected to linger in the waters south of the Ogasawara chain through around Monday the 2nd, before gradually shifting its course northward around Tuesday the 3rd.

Swells generated by the typhoon are reaching the Ogasawara Islands, and there is a risk of warning-level high waves around the 3rd. Given the typhoon's slow movement and its expected approach toward the Ogasawara Islands while remaining a powerful storm, the impact on the region could be prolonged.
Please exercise extreme caution regarding violent winds, high waves, and potential landslides triggered by heavy rain; stay tuned for the latest typhoon updates.

While there is still uncertainty regarding the typhoon's path from the 5th onward, areas along the Pacific coast of Honshu should be on alert for high waves. Furthermore, depending on the typhoon's future trajectory, weather conditions across Honshu could be significantly affected. Please be sure to check for the latest weather information as it becomes available.

[Typhoon Information] Typhoon No. 31 is moving northward with very strong intensity; it is expected to meander in the waters near the Ogasawara Islands.

2026/10/31 07:32

As of 6:00 a.m. today, Saturday the 31st, Typhoon No. 31 (In-fa)-a very strong storm-is located near the Ogasawara Islands and is moving west-northwest at a speed of 20 km/h.

Typhoon No. 31 - Saturday, the 31st, 6:00 a.m.
====================================
Center Location: Near the Ogasawara Islands
Size: -
Strength: Very strong
Movement: West-northwest, 20 km/h
Central Pressure: 940 hPa
Maximum Sustained Wind Speed: 45 m/s (near the center)
Maximum Gust Speed: 65 m/s
====================================




Outlook
Typhoon No. 31 is expected to move slowly northward in the vicinity of the Ogasawara Islands.
Following this, it is projected to shift briefly toward the east through tomorrow, Sunday the 1st, before turning back toward the west?essentially "wandering" (following an erratic path) near the Ogasawara Islands.
The area around the Ogasawara Islands is expected to remain under the influence of the typhoon for an extended period, from Saturday the 31st through Thursday the 5th; please exercise caution regarding high waves accompanied by swells. Additionally, as the system is expected to approach the vicinity of the Ogasawara Islands on Thursday the 5th, please remain alert and take precautions against violent winds and heavy rain.



Subsequent Path
While there is a high degree of uncertainty regarding its future path, several forecast models suggest that the system will turn toward the northeast in the waters near the Ogasawara Islands during the latter half of next week, moving away to the east of Japan.
At present, the likelihood of the system making landfall on the Japanese archipelago is considered low. However, as the areas around Honshu may be affected by moist air flowing from the typhoon, there is a risk that active rain clouds could develop along the Pacific coast during the latter half of next week. Please continue to check for the latest typhoon information.

Very strong Typhoon No. 31 is moving slowly northward; please stay alert for updates on its future path.

As of 3:00 PM today, Friday the 30th, Typhoon No. 31 (In-fa)?a very strong storm?is moving west-northwest through the Mariana Islands at a speed of 35 km/h.




Over the weekend, the typhoon is expected to move slowly northward south of the Ogasawara Islands. Subsequently, through Wednesday the 4th, it is projected to continue its slow northward progression while moving westward. The Ogasawara Islands are expected to enter the typhoons storm warning zone by Wednesday the 4th. As the storm will maintain its very strong intensity while moving north, caution is advised regarding high waves and swells in the Ogasawara Islands on Wednesday the 4th.

While the likelihood of the typhoon approaching or making landfall on Honshu is considered low, moist air from the storm may flow into a weather front near Honshu on Thursday the 5th, potentially leading to significant rainfall. As there is still a high degree of uncertainty regarding the storm's path, please be sure to check for the latest updates regularly.

Watch for sharp temperature fluctuations this weekend; snow is also possible in northern Japan.

2026/10/30 14:10

Today, Friday the 30th, a trough of low pressure is situated over Japan, leading to atmospheric instability across a wide area. A band of precipitation stretches from northern Japan to western Japan, with thunderstorms already observed in the Chugoku region and over the Sea of ??Japan.

The precipitation is expected to gradually shift eastward through this evening, with conditions in western Japan likely to begin improving tomorrow. As the weather clears, temperatures will rise across eastern and western Japan; in Tokyo, the high is expected to reach 25C or above?a "summer-like" day.





However, this warmth will be short-lived; by the evening of tomorrow, the 31st, a "winter-type" pressure pattern is expected to develop. Even in the Kanto region, where the daytime may be warm enough to cause some perspiration, the north wind will make it feel quite chilly by nightfall. Please be sure to bring a jacket if you are heading out.



In Hokkaido, cold air in the upper atmosphere may bring snow on the 1st.
Temperatures will fluctuate significantly, so please take extra care of your health.
There will be large temperature variations?not only from day to day, but also throughout the course of a single day?so please choose your clothing accordingly to stay comfortable.

Weather for today, Friday the 30th: Cloudy or rainy across the country, with a risk of thunderstorms—particularly in western Japan. Conditions will begin to improve from the west in the afternoon.

2026/10/30 07:58

Today, Friday the 30th, a trough of low pressure will bring cloudy and rainy weather to a wide area, stretching from Kyushu all the way to Hokkaido.




In western Japan, in particular, some areas may experience heavy rainfall accompanied by thunderstorms; please exercise caution.
By the afternoon, the rain will gradually taper off from the west, and some parts of the Kyushu, Chugoku, and Shikoku regions may see the sun break through.



Across much of western Japan, rain is likely throughout the morning, with some areas seeing heavy downpours accompanied by thunder.
As the afternoon progresses, the rain will gradually clear from the west; by early afternoon in Kyushu, and by evening in the Chugoku and Shikoku regions, many areas will see the return of sunny intervals.

In the Kinki and Tokai regions, rain is likely to persist into the afternoon, meaning you will likely need to keep an umbrella with you all day.

In the Kanto region, skies will remain mostly cloudy. Rain is expected?particularly during the morning?along the Pacific coast, including the Boso Peninsula, and some areas in the northern part of the region may also see rain.
There is also a possibility of scattered showers across a wide area in the south, including central Tokyo.

Across Hokkaido and along the Sea of ??Japan side of the Tohoku region, skies will be mostly cloudy, with rain expected in some places.

Along the Pacific side of the Tohoku region, clouds will also spread, leading to generally unsettled weather.

Very strong Typhoon No. 31 (In-fa) is expected to move westward for the time being; please keep a close watch on its subsequent trajectory.

2026/10/30 07:38

As of 06:00 today, Friday the 30th, Typhoon No. 31 (In-fa)?a very strong storm?is moving west-northwest through the Mariana Islands at a speed of 35 km/h.



The typhoon is expected to slow down south of the Ogasawara Islands over the weekend, before continuing on a westward path into next week. Please be aware that, depending on its exact track from the middle of next week onward, it could have a significant impact on the Ogasawara Islands.

-----------------------------
Typhoon No. 31 ? As of 06:00, Friday the 30th
Center location: Mariana Islands
Size: -
Intensity: Very strong
Movement: West-northwest at 35 km/h
Central pressure: 940 hPa
Maximum sustained wind speed: 45 m/s (near the center)
Maximum instantaneous wind speed: 65 m/s
------------------------------




Typhoon No. 31 is expected to move in a westerly direction today, Friday the 30th.

Subsequently, between Saturday the 31st and Sunday, November 1st, it is projected to shift slightly toward the north while slowing down over the waters south of the Ogasawara Islands. As the storm will maintain its "very strong" intensity, please exercise caution regarding high waves and swells in the Ogasawara Islands, even if you are some distance from the center.


From Monday the 2nd onwards, the system is expected to move westward again. It may subsequently shift its course toward the north and continue moving northward. While the likelihood of it approaching or making landfall on Honshu is considered low, it could interact with a weather front, potentially leading to significant rainfall across parts of Honshu during the latter half of next week.

As there is still a high degree of uncertainty regarding its path, please be sure to check for further updates regularly.

【daily‑changing weather】large temperature swings, with attention also on typhoon no.31(commentary: weather forecaster Junko miyake)

2026/10/29 14:58

weather points ahead
periodic changes in the weather
attention to the movement of typhoon no.31



a low-pressure system will bring rain, followed the next day by a winter-type pressure pattern,
and then the following day by high pressure.
this day-to-day cycle is expected to continue.

be mindful of daily weather changes and temperature swings.

details on typhoon no.31 will be provided later in the report.



toward tonight, the center of the high pressure system will move east of japan,
and moist air will flow in along the edge of the high.
even areas with sunshine now will gradually see increasing cloud cover.

a low-pressure system and a front will also approach hokkaido,
bringing rain and thunderstorms in some areas.

furthermore, a front is expected to form along the southern coast of honshu through tomorrow,
and widespread rain is likely.



now let's look at the rain cloud forecast.
from this evening (fri the 29th), rain is expected to begin in hokkaido.
there may be periods of heavier rain with thunder.

late tonight, snow may fall in high-elevation areas of hokkaido,
but most places will see rain.
thunderstorms are also possible,
so please watch for sudden heavy rain, lightning, and gusty winds.

later at night, rain will begin in parts of western japan as well.
after midnight, rain is also expected to start in the kanto region.



toward dawn, coastal areas of chiba may see stronger rainfall with thunder.
there is a chance of heavy rain.

in shikoku, including kochi, heavy rain with thunder may occur from the morning,
and in the kinki region from late morning.

in the afternoon, southern kanto will see only spotty light rain,
but northern kanto will become more prone to rain from the evening.
if you are heading out tomorrow, having an umbrella will be reassuring.

tomorrow night, some rain may linger in the tokai, kinki, and hokuriku regions.



now let's look at typhoon no.31.
as of 9 am today, it is near minami-torishima with very strong intensity,
moving westward at about 30 km/h.

its central pressure is 940 hPa, and because it will continue traveling over warm waters,
it is expected to maintain this strength through around nov 3.

depending on its track, it may approach the ogasawara islands, including chichijima, around nov 1.

the chance of entering the storm-force wind area is low,
but the strong-wind area may come close.
winds may strengthen and waves may become higher around nov 1,
so caution is advised.



the track after nov 3 remains uncertain.

a strong high pressure system will extend from the continent,
so the typhoon may continue westward,
or it may turn northeast.
please continue to check the latest updates.



now for the weather across the regions.
clouds will thicken through the rest of today.
in sapporo, rain will begin from evening,
and in western japan from tonight.
thunderstorms are likely in sapporo tonight.

tomorrow (sat), many areas will see rain.
tokyo and sendai show cloudy icons,
but light rain is possible.
please bring rain gear just in case.

in osaka and nagoya, temperatures will be lower tomorrow due to rain.
in sapporo, southerly winds will keep temperatures relatively high throughout the day.



weekly forecast:
on sunday the 1st, cold air will flow in and sapporo may see snow again.

on the 2nd, widespread rain is expected,
and on the 3rd, cold air will flow in again,
making snow more likely in sapporo through the 4th.

temperature swings will be significant,
so please take care to avoid getting sick.

【kanto】heavy rain and thunderstorms possible tomorrow (fri), plus the latest on typhoon no.31(commentary: weather forecaster Junko miyake)

2026/10/29 14:46

today (thu), the kanto region will see the weather deteriorate toward the night.



this is tonight's forecast weather chart.
the center of the high pressure system will move east of japan,
and warm, moist air will flow into the kanto region from the south.
clouds will gradually thicken through the evening.

furthermore, a front is expected to form along the southern coast of honshu through tomorrow.
due to its influence, the kanto region is likely to see rain tomorrow.



now let's look at the forecast for rain clouds.
starting from tonight:
around 9 pm, rain is expected to begin in areas such as chiba and ibaraki.
rain clouds will be more active along coastal areas through tomorrow morning.
in places like choshi and tateyama in chiba, heavy rain with thunder may occur toward dawn tomorrow.



after that, the rainy conditions will continue,
but around midday, rain clouds over chiba and ibaraki will gradually move eastward.

in the afternoon, the southern part of kanto will only see occasional light rain,
but northern kanto will become more prone to rain from tomorrow evening.
if you are going out tomorrow, having rain gear will be reassuring.



another point of concern is the movement of the typhoon.
currently, typhoon no.31 is near minami-torishima with very strong intensity,
moving westward at about 30 km/h.

its central pressure is 940 hPa, and because it will continue traveling over warm waters,
it is expected to maintain its strength through around nov 3.

depending on its course, it may approach the ogasawara islands, including chichijima, around nov 1.
the chance of entering the storm-force wind area is low,
but the strong-wind area may come close.

around nov 1, winds may strengthen and waves may become higher in the ogasawara region,
so caution is needed.



the forecast track after nov 3 remains highly uncertain.

a strong high pressure system will extend from the continent,
so the typhoon may continue westward,
or it may turn northeast.
please continue to check the latest information.



now let's look at the weather across the region.

clouds will thicken through the rest of today.
tomorrow, even areas without a rain icon may see light rain,
so carrying rain gear is recommended.

southerly winds will blow during the day tomorrow, keeping temperatures high.
tokyo will reach 21 degrees, and yokohama will rise to 23 degrees.



finally, the weekly forecast.

this weekend will be widely sunny.
saturday will be quite warm,
but sunday may feel chilly due to northerly winds.

culture day on nov 3 will also be sunny across the region.
it will be pleasantly mild during the day - perfect for outings.

however, on thu the 5th, widespread rain is expected.
temperatures will drop, and the rain may feel cold.
with large temperature swings ahead, please take care of your health.

Typhoon No. 31 (In-fa) is moving westward with very strong intensity.

2026/10/29 11:54
