[Latest Typhoon Information] Typhoon No. 26 has intensified into a "very strong" storm. Okinawa Main Island and the Daito Islands region should brace for stormy weather through tomorrow; the storm is then expected to move northeastward south of Honshu.

2026/09/27 17:41

As of 4:00 PM today, Sunday, the 27th, Typhoon No. 26 (Surigae)?classified as "very strong"?is estimated to be moving northeast at 15 km/h over the waters approximately 100 km south-southeast of Naha City. Residents of the Okinawa main island and the Daito Islands region need to remain alert and cautious regarding prolonged strong winds and high waves.

------------------------------------
Typhoon No. 26 ? As of 4:00 PM, Sunday, September 27
Center Location: Approx. 100 km south-southeast of Naha City
Size Classification: N/A
Strength Classification: Very Strong
Movement: Northeast at 15 km/h
Central Pressure: 960 hPa
Max. Wind Speed: 45 m/s (near center)
Max. Instantaneous Wind Speed: 60 m/s
------------------------------------



The typhoon is expected to continue moving northeast through the waters near the Okinawa main island. Although it is forecast to weaken to "strong" status by tomorrow, Monday the 28th, it is expected to pass between the Okinawa main island and the Daito Islands region at a relatively slow speed of around 15 km/h, raising the risk of prolonged impacts.

Caution is advised regarding strong winds, gale-force winds, and high waves accompanied by swells in the Okinawa Main Island and Daito Islands regions. The Daito Islands region, in particular, may experience severe weather conditions, peaking tomorrow as the storm makes its closest approach. Please be extremely vigilant against flying debris, fallen trees, and power outages; it is advisable to move items that could easily be blown away indoors today.




Additionally, active rain clouds are visible near the center of the typhoon. These clouds may affect the Daito Islands region tomorrow, the 28th (Monday), necessitating caution regarding heavy rain. Evacuating after winds and rain have intensified is dangerous; please pay close attention to information from local authorities and prioritize early evacuation.

Looking further ahead, the forecast circle is notably large for the period between the 30th (Wednesday) and October 2nd (Friday). This does not represent the physical size of the typhoon itself, but rather indicates a high degree of uncertainty in the forecast.

The latest predictions suggest the typhoon will not approach Honshu as closely as initially anticipated; however, if it follows a more northerly path, there is a possibility it could approach the Pacific coast of Honshu.
Furthermore, an autumnal rain front is currently stalled near the southern coast of Honshu. While the typhoon is located south of Honshu, warm, moist air will flow toward this front, potentially causing rain clouds to develop and intensifying rainfall in the area.
As there is a possibility of heavy rain reaching warning levels, please continue to check for the latest updates regularly.

A low-pressure system is located over the northern Sea of ??Japan and is moving eastward.
A high-pressure system lies east of the Kuril Islands, extending its influence toward northern Japan.
An autumn rain front stretches from the Asian continent, across Kyushu, and out to the waters east of Japan. A low-pressure system has formed along this front near the Tsushima Strait and is moving eastward.
Typhoon No. 26 is located south of Okinawa and is moving northeastward.



Today, the 27th (Sunday), the low-pressure system over the Sea of ??Japan is Today, Sunday the 27th, moist air from Typhoon No. 26 is intensifying the activity of the autumn rain front, causing heavy rainfall, particularly in northern Kyushu. Very intense rain has been recorded, with hourly precipitation reaching 71.0 mm in Omuta City, Fukuoka Prefecture, and 66.5 mm in Omura City, Nagasaki Prefecture.



At 9:00 AM today (Sunday the 27th), the Fukuoka Regional Meteorological Observatory and the Kumamoto Local Meteorological Observatory issued a "Meteorological Disaster Prevention Bulletin" (an imminent forecast for a linear precipitation zone). There is an increasing likelihood that a linear precipitation zone will form over the Chikugo region of Fukuoka Prefecture and the Kumamoto region of Kumamoto Prefecture through the early afternoon, bringing continuous, very intense rainfall to the same area. This creates a risk of a rapid escalation in the danger of life-threatening disasters.



Additionally, Level 4 heavy rain warnings and Level 4 landslide warnings have already been issued for some areas. As conditions conducive to rainfall will persist into tomorrow, please remain strictly vigilant against landslides, flooding in low-lying areas, and rising or overflowing rivers.



Please check rain cloud radar forecasts and evacuation information issued by local authorities. Assess your surroundings and move away early from hazardous areas, such as locations near cliffs or rivers. Also, be extremely cautious of potential flooding in underpasses.

====================================
Center location: South of Okinawa
Movement speed: North-northwest at 10 km/h
Central pressure: 996 hPa
Maximum sustained wind speed: 25 m/s (near the center)
Maximum instantaneous wind speed: 35 m/s
====================================



Typhoon No. 26 is expected to move northward while maintaining a gale-force wind zone. By tomorrow, Sunday the 27th, it is forecast to intensify into a "strong" typhoon, with maximum sustained winds near the center reaching 35 m/s or higher.
From the 27th onwards, the storm is expected to gradually shift its course toward the east; due to its slow movement, there is a risk of prolonged impacts in the Okinawa and Amami regions. Starting today, the 26th, coastal waves will gradually rise?accompanied by swells?and winds will also begin to strengthen. Rough weather is expected to persist around Okinawa through approximately the 29th.



Please remain alert for strong winds, high waves, and landslides associated with warning-level heavy rainfall; also, exercise great caution regarding flooding and inundation caused by rising tide levels due to storm surges.

Regarding its subsequent path, the forecast circle is large, indicating a high degree of uncertainty in the prediction. Depending on how the situation develops, the storm could approach the Kyushu or Shikoku regions and feed warm, moist air into the autumnal rain front lingering near Honshu; this could intensify the front's activity and potentially lead to heavy rainfall across Honshu.

Please pay close attention to the latest typhoon information as it becomes available.

Weather forecast for today, Saturday the 26th: A stalled autumn rain front brings steady rain across a wide area from western to eastern Japan.

2026/09/26 06:35

Today, Saturday the 26th, an autumn rain front is stalling over the main Japanese island (Honshu), stretching from western to eastern Japan. A band of rain clouds associated with this front extends from west to east, bringing rain to a wide area across these regions.



In the Kanto area, heavy rain has already been observed in some locations since the early hours of the morning; as of 6:00 AM, developed rain clouds are visible near Ibaraki and Chiba Prefectures. Rain is expected to continue, with the risk of localized heavy downpours accompanied by thunder.
Residents of Chiba Prefecture, in particular?especially in areas that previously suffered significant damage from Typhoon No. 25?should exercise extreme caution regarding the potential for new heavy rain disasters.



The band of rain clouds associated with the front is forecast to slowly move southward as the day progresses. While the rain may gradually taper off in areas facing the Sea of ??Japan, it is likely to intensify in some areas facing the Pacific Ocean. In Kyushu, heavy rain accompanied by thunder is expected in some places from midday onwards; please remain alert to changing rainfall conditions.
Even if it is not raining when you leave home, please be sure to carry an umbrella.

In Northern Japan, regions such as Hokkaido and northern Tohoku will likely see sunny skies and plenty of sunshine. However, southern Tohoku is expected to experience weather prone to rain.

Due to the rain, daytime temperatures will not rise significantly, and many areas will see a sharp drop in temperature compared to yesterday. Please not only prepare for the rain but also bring an outer layer or similar garment so you can adjust your clothing to maintain a comfortable body temperature. Meanwhile, in southern Kyushu and Okinawa, temperatures will reach 30 C or higher in many areas, making it feel hot and humid.

Risk of heavy rain due to successive approaching typhoons; check landslide risks on hazard maps.

Typhoon No. 25, which formed in the Mariana Islands on September 16,
approached the Ogasawara Islands on the 19th,
and subsequently neared the Izu Islands and the Kanto-Koshin region on the 21st as a large, powerful storm.

The Kanto-Koshin region experienced record-breaking rainfall between the 19th and 21st, with total precipitation exceeding 800 mm in the Izu Islands, 500 mm in Shizuoka Prefecture, and 450 mm in Chiba Prefecture.

Due to this heavy rain, Level 4 landslide danger warnings were issued across 89 municipalities in seven prefectures (these warnings have since been lifted).
Over 100 landslides were reported in Chiba Prefecture, and landslides resulting in casualties occurred in Chiba, Kanagawa, and Miyazaki prefectures.

Meanwhile, Typhoon No. 26 has now formed,
and it is expected to approach the Okinawa region with strong intensity around the 27th.
Afterward, it may shift its course to the northeast and travel along the southern coast of Honshu. Depending on its path, there is a risk of heavy rain once again affecting the Honshu area.

In areas where the ground has already been loosened by previous rainfall, landslides can occur even with only a small amount of additional rain.
Please check hazard maps before heavy rain arrives to identify areas at risk.



You can search for hazard maps for your local area
using the "Wagamachi Hazard Map" (My Town Hazard Map) service.
By selecting the area you wish to check on the map,
you can view the disaster prevention page provided by the local government.

Sediment disaster hazard maps use color-coding to indicate areas requiring caution or vigilance.



Yellow: Sediment Disaster Warning Areas (areas at risk of sediment disasters)

Red: Sediment Disaster Special Warning Areas (areas where a disaster could cause building damage or pose a threat to human life)
*Note: Uninhabited mountainous areas may not be designated.



These maps also indicate evacuation shelters and assembly points, making them useful not only for understanding sediment disaster risks but also for checking evacuation routes.
Please use the hazard map as a reference to discuss disaster preparedness with your family and those close to you.



During heavy rain, please use the warnings and advisories issued by the Japan Meteorological Agency (JMA), as well as the JMA's "Kikikuru" (Landslide/Flood Risk Map) website, to help decide when to evacuate.
However, even if no official warning has been issued, it is crucial to evacuate without hesitation if you notice anything unusual about nearby cliffs or slopes.



Once a sediment-related disaster occurs, it can cause catastrophic damage to lives and property. In particular, debris flows and cliff collapses happen so rapidly that there is often not enough time to evacuate safely.

Make sure to check the risk of sediment-related disasters in your area during normal times, and commit to evacuating early when heavy rain is forecast.
We encourage you to take a look at your local hazard map.
