Typhoon No. 8 is expected to come close to Tokai and Kanto-Koshin during the day on the 13th and make landfall.
There is a risk of heavy rain on the Pacific side, and a linear rain belt is expected to occur on the 13th in the Tokai region such as Shizuoka Prefecture.
Please be sure to check the latest information as it overlaps with the Obon season.
According to observations by the Japan Meteorological Agency, Typhoon No. 8 is in the south of Japan at 3:00 pm on the 12th and is slowly moving north-northeast.
The central pressure is 1002 hectopascals, the maximum wind speed is 18m near the center, the maximum instantaneous wind speed is 25m, and there are no stormy areas, but within 330 km southeast of the center and within 165 km northwest of the center, strong winds of 15 m or more. is blowing
After this, it is expected to pick up speed a little and make landfall at Tokai and Kanto-Koshin during the daytime on Saturday the 13th.
Due to the warm and moist air around the typhoon, rain clouds have developed locally around Shizuoka Prefecture, and the rain is intermittently increasing.
Due to the approach of the typhoon, extremely heavy rain of 50 mm or more per hour accompanied by thunderstorms is expected locally in Tokai and Kanto Koshin, and there is a risk of heavy rain until Sunday the 14th.
In the Tokai region, including Shizuoka Prefecture, during the day on the 13th, a linear rain belt with a series of developed rain clouds may occur, and the risk of disasters may increase sharply.
The amount of rain falling in the 24 hours until the evening of the 13th
is expected to be
300 mm in Shizuoka Prefecture
, 200 mm in Kanto Koshin
, 150 mm in the Tokai region excluding Shizuoka Prefecture,
and 100 mm in the southern Tohoku region.
After that, the 24-hour rainfall until the evening of the 14th
is expected to be 100
to 200 mm in Shizuoka Prefecture, 100
to 150 mm in Kanto Koshin,
and 50 to 100 mm in the Tokai region and the southern Tohoku region, excluding Shizuoka Prefecture.
There is a risk that the total rainfall will increase considerably, mainly in
If a linear rain belt occurs in the Tokai region, there is a risk that the amount of rain will increase locally.
In addition, the wind is expected to gradually increase, and very strong winds are expected to blow mainly on the sea.
In Kanto, the Izu Islands, and Tokai, the maximum wind speed is expected to be 20 meters on the 13th, the maximum instantaneous wind speed is 30 meters, and the wave height is expected to be 5 meters with swells.
The Japan Meteorological Agency has called for caution against landslides, flooding of low-lying land, sudden rises in rivers, and high waves.
It is also necessary to be careful of strong gusts such as strong winds, lightning strikes, and tornadoes.
Please be sure to check the latest information as it overlaps with the Obon season.
Outdoor leisure activities such as the sea and rivers require sufficient caution before a typhoon approaches.
Impact on traffic
Due to the approach of Typhoon No. 8, traffic is expected to be affected in some areas.
According to JR companies, the Tokaido, Tohoku, Joetsu, Hokuriku, and Yamagata Shinkansen lines are currently not scheduled to be suspended due to the approach of the typhoon on the 13th. This means that there may be suspensions or delays between the station and Akita Station.
On the conventional lines, the Kururi Line, which connects Kisarazu Station and Kazusa Kameyama Station in Chiba Prefecture, will be suspended from the evening of the 13th to midnight, and the Sobu Main Line, Narita Line, Kashima Line, Uchibo Line, which are under the jurisdiction of the JR Chiba branch office. It means that the Sotobo Line and Togane Line may stop operating after the evening.
Regarding major railways in Tokyo, some say that trains may be delayed or suspended due to wind and rain on the 13th, but at this time there are no planned suspensions.
According to NEXCO East Japan and the Metropolitan Expressway, the Kanto-Koshin Expressway is currently not scheduled to be closed due to the approach of the typhoon.
Since the impact on transportation due to the approach of the typhoon will depend on the situation such as how it will rain in the future, transportation companies are calling for checking the latest information on their websites and so on, and traveling with plenty of time to spare.
Typhoon No. 8 Summary of caution points
Typhoon No. 8 develops into a typhoon near Honshu, and is likely to approach or make landfall in Tokai and Kanto-Koshin tomorrow.
Here are some things to watch out for.
Risks unique to urban areas
The first is power and course.
As of 3:00 pm on the 12th, the force is 1002 hectopascals.
The maximum wind speed near the center is 18 meters, which is not very strong for a typhoon.
However, it tends to develop until just before the approach, and rain clouds are gathered near the center and on the south side, and there is a risk that the rain and wind will suddenly intensify just before the approach.
Also, regardless of the strength of the typhoon, you need to be vigilant against rain.
This typhoon is on a course that may approach or make landfall in urban areas such as the southern part of the Kanto region, so it is necessary to pay attention to the risk of flood damage unique to urban areas.
If drainage cannot keep up, water tends to collect on land that is lower than the surrounding area and on narrow roads, creating a rapid river-like flow that can jeopardize your feet.
In particular, "underpasses" that pass under railroad tracks and roads are prone to flooding in heavy rain, and places that are about 1 meter lower than the surroundings are difficult to see at a glance, and people who were on board without noticing died. Accidents occur frequently.
If a car is submerged in water, the engine will stop at about 30 centimeters, and if it is more than 50 centimeters, the car will float and be swept away.
If the weather suddenly deteriorates or the visibility is poor, do not overdo it, park your car in a safe place and wait for the wind and rain to subside.
Also, in urban areas, there are many buildings and roads are paved, making it difficult for rainwater to seep through.
This is a phenomenon called "inland flooding," in which the drainage function of sewers cannot keep up and water overflows to the ground.
Increase in total rainfall around Shizuoka Heavy rain warning
On the other hand, Shizuoka Prefecture and its surroundings, which are covered by rain clouds that have developed well before the typhoon approaches, are likely to receive a large amount of total rainfall.
On the 13th, the rain clouds developed by the typhoon itself will cover one after another, causing extremely heavy rain.
According to the Japan Weather Association, Shizuoka Prefecture will receive around 400mm of rainfall in 72 hours over the 15th.
Risk of landing during the Obon season Check information before heading to a resort
Also, the timing of the approach and landfall of the typhoon may coincide with the time when many people return to their hometowns or go to resorts or return home.
The wind is gradually getting stronger and the sea is expected to swell.
You also need to be careful about heavy rain and high waves.
Depending on the strength of the rain and wind, transportation networks such as railways, expressways, and air flights may be affected, so check the latest information before going out, and consider changing schedules and itineraries depending on the situation. Please try to
What is "prediction of linear rain bands"?
The Japan Meteorological Agency is calling for vigilance in its June weather information if the risk of the occurrence of a ``linear rain belt'' in which developed cumulonimbus clouds are linked one after another increases.
It is announced that heavy rain is expected ``from half a day to 6 hours'', and the range of calling is mainly carried out in each of 11 regions nationwide, and the target time zone is ``morning'' and ``night''. It will be announced with width.
The Japan Meteorological Agency wants people to have a sense of crisis when information is issued, and to prepare for disasters by checking hazard maps, evacuation sites, and evacuation routes.
On the other hand, there are limits to accuracy.
According to the Japan Meteorological Agency, based on past cases, the "hit rate" is about 1 in 2 nationwide, and about 1 in 4 in local areas. It means that there are about 2 times out of 3 times.
It does not mean that ``areas without forecasts are safe''.
If the situation suddenly worsens, move to a safer place as soon as possible.
When developed cumulonimbus clouds flow in one after another and very heavy rain continues to fall in the same place, 'information on remarkable heavy rain' is announced.
However, by the time this information is released, the risk of landslides and floods will rise sharply, and it may already be dangerous to go outside.
The Japan Meteorological Agency is calling for early evacuation based on local government evacuation information.
