The danger of approaching and landing
(Chief Director Nakamoto Nakajima)
Typhoon No. 10 will develop to a special warning level in the future:
▽5th night to 6th morning in the Okinawa region,
▽6th to 7th from Amami to Kyushu ,
There is a risk of approaching or landing.
In areas where typhoons approach, record heavy rain, storms, high waves, and high tides may occur, and it is expected that rivers will increase and warm and moist air will flow in, resulting in heavy rain on the Pacific coast west of the Kii Peninsula. there is.
We have set up a meeting place so that we can take action to protect ourselves from these disasters before the typhoon approaches.
Today, the Meteorological Agency and the Water Management National Land Conservation Bureau will hold a joint meeting. The Meteorological Agency will explain the course of the typhoon, rain and wind, and the Water Management National Land Conservation Bureau will explain the flooding of rivers.
Record heavy rain, storms, high waves and high tides
First, let's look at the future weather forecast for Typhoon No. 10.
Typhoon No. 10, which is extremely strong, is expected to develop into a special warning class force in the future, and will approach the Okinawa region from the night of the 5th to the morning of the 6th, and will continue northward while maintaining the power of the special warning class. , There is a risk of approaching or landing from the Amami region to Kyushu from the 6th to the 7th.
There is a possibility of being greatly affected in a wide range.
In areas where typhoons approach, record heavy rainfall, storms, high waves, and high tides may occur, and maximum caution is required.
Thank you for completing the preparation for the typhoon by the 4th.
In addition to paying attention to the latest typhoon information announced by the Japan Meteorological Agency, pay attention to the weather information such as early warning information and warning warnings announced by the weather stations in each region, and take early measures to protect your own life and the lives of important people. Please.
Evacuate before you can't move
(Ministry of Land, Infrastructure, Transport and Tourism Director Takamura) In the
future, heavy rainfall due to typhoons may cause flooding and flooding of rivers and flooding and flooding near the estuary of the coast due to high tides.
Especially in southern Kyushu, Kagoshima prefecture and Miyazaki prefecture, there is an increasing risk of flooding even large rivers such as nationally managed rivers.
Also, in other regions, as typhoons approach, such dangers will become apparent, so please keep your eyes on the weather information.
Please check the flood hazard maps, etc. created by the municipalities as soon as possible to understand the possibility of inundation, evacuation site/route, etc., and prepare for evacuation.
In areas where typhoons are approaching, it may be impossible to move due to storms when the river increases.
Please secure your safety as soon as possible by evacuating to a safe place before the wind becomes strong.
Prior release of dams such as Kyushu
We plan to release dams in advance in Kyushu and other areas, and some have already done so.
The amount of water in the river may increase from the time it is fine before the heavy rain, so please do not stay in the river as much as possible regardless of the weather.
You can check the river water level and risk information on river disaster prevention information, risk distribution, and hazard map portal sites.
Please pay attention to the weather/river information and the evacuation information of the municipalities so that you can take early action.
Future path and power
(Chief Director Nakamoto, Meteorological Agency)
I would like to explain the weather outlook.
Looking at the weather map at 6am and the satellite image at 9am today, when you look at the center of the typhoon, it is a developed cloud, and the eyes of the rain cloud and the typhoon have become very clear.
It shows that it is well developed.
Looking at the path forecast of the typhoon, it is currently a very strong typhoon with 925 hectopascals at 9 o'clock and a maximum wind speed of 50 meters.
We think that it is slightly more advanced than expected on the 3rd.
After that, at 9 am on the 5th, we expect a severe typhoon of 920 hectopascals.
After that, we are approaching the Okinawa region from the 5th to the 6th, and then approaching and landing from Amami to Kyushu from the 6th to the 7th, and we are making our way.
The rainfall is
From 12 o'clock on 6th to 12 o'clock on 7th, it shows the estimated rainfall when approaching Amami to Okinawa and Kyushu.
Also, the amount of rainfall will continue after this, so I think that there is a good chance that it will not end and that it will increase again in the evening.
First, in the Okinawa region, the wind gets stronger on the 4th.
And it will be a big deal at sea, and there is a danger of storms and violent weather on the 5th and 6th, and warning-level rain and storm surges.
In Amami, southern Kyushu, and northern Kyushu, there are places where the sea is big on the 5th, and storms are severe on the 6th to 7th, and there is a danger of heavy rain storms of the warning level.
The Amami region believes that the wind will be very strong on the 5th.
To Shikoku/China/Kinki The Pacific side of East Japan will experience high warning waves on the 6th to 8th, while storms and storm surges may occur in Shikoku/China. There is a risk of heavy rain.
Since the winds toward the south and southeast are blowing, we are thinking that the rain will be concentrated especially on the slopes from south to east.
Confirm the hazard map created by the municipality
As is well known, each municipality creates and publishes flood hazard maps based on the inundation area map.
The materials shown are examples of the Oyodo River system and Miyakonojo City, Miyazaki Prefecture.
If it becomes a really big flood, it is assumed that it will flood in the area shown in this figure.
It is a situation that we do not want to happen very much, but since the typhoon this time is a very strong force, please act with the kindness that there may be such a situation.
Local governments consider evacuation information considering the highest risk
Q. When municipalities issue evacuation information, there are many cases where evacuation advisories and evacuation orders are issued after the water level rises in large rivers. How do you call the municipalities?
(Director, Nakamoto, Japan Meteorological Agency)
A. Because it is a typhoon, it is easy to see the storm warning area. There are various things such as when the storm radius is visible, there are various things, but the time zone caused by the phenomenon phenomenon Will change.
As the crisis will change, I want you to check the situation around you without being caught before the wind blows, consider the one with the highest risk among them, and instruct evacuation. Therefore, we would like to cooperate with the local government and give advice for that purpose.
Q. In what I mentioned as the possibility of warning class, in Southern Kyushu and Amami, the waves came first, and the storm surge came after that, but I caught the phenomenon that occurs first in them. Is it all right to understand that I want you to evacuate early?
(Manager, Nakamoto, Japan Meteorological Agency)
A. That's right.
Not all phenomena are progressing at the same time, and there are still characteristics of the land, so I would like you to grasp that and respond to the risk that comes earliest and take measures. I will.
Is it comparable to the largest typhoon after the war
Q. It may have developed considerably in the actual situation, but has the sense of crisis in the field increased based on that?
(Chief Director Nakamoto of the Japan Meteorological Agency)
A. Yesterday, the development is progressing slightly, but I think that the course and scenario have not changed so much as the progress of the typhoon.
We are saying that we should take measures for that today, unless we were prepared when the weather was stable, or if there were sudden winds or rain, it would be quite difficult. I don't think I can proceed, so I made such a call.
Q. In the materials you have distributed, you mention things like No. 21 of 2018 and last year's Boso Peninsula typhoon. Should you imagine that the damage will exceed that?
(Manager, Nakamoto, Japan Meteorological Agency)
A. It depends on the course, but the typhoon forces themselves are very different.
Speaking of the typhoon forces of the last year, there are those that are not special warning class, and those that exceed it, so I think that it may cause more damage depending on the course.
Q. Is the typhoon's power this time almost a special warning level?
(Chief Director Nakamoto of the Japan Meteorological Agency)
A. This typhoon is very powerful regardless of whether it will be a special warning, so if you approach it, it will become a very large, record-breaking storm. However, I would like you to be vigilant regardless of whether or not this happens.
Q. Can it be said that it is in no way inferior to the largest postwar typhoons such as the Isewan Typhoon?
(Director Nakamoto, JMA)
A. Looking at the current forces and expected central atmospheric pressure, I think that they are comparable to those.
How long does the typhoon last?
Q. The central pressure of a typhoon is said to drop to 915 hectopascals at 9 o'clock on the 6th. Is this the bottom?
Also, in the Kinki region, warnings for storm surges are until the first half of the 4th and 5th, and there is a fear of a wave warning on the 6th and 7th. What is the break?
(Director Nakamoto, Meteorological Agency)
A. Regarding whether or not the bottom is 915 hectopascals, I think that the most developed one is 915 hectopascals.
(Person in charge of the Meteorological Agency's Forecasting Division)
Regarding storm surges, we are currently issuing storm surge warnings in northern Hyogo Prefecture.
Originally, this period corresponds to the period when the astronomical tide level is high, and the tide level is the highest factor, and in addition to this, it seems that the warning and warning standards are somewhat exceeded due to weather conditions. Since it is in such a situation, the warning is currently announced, so it is a possibility of warning level.
Q. How long will the state of development continue?
(Person in charge of the Meteorological Agency's Forecasting Division)
A. I think that it will be about 915 hectopascals from the point slightly ahead of what we are currently forecasting, and that we will be approaching Amami Oshima near that power.
About that, the sea surface temperature is higher than 30 degrees Celsius on the southwest side or the east side or the south side of Amami Oshima or the so-called Nansei Islands, and as the typhoon progresses northwest, it enters a place where the sea surface temperature is low.
In addition, the atmospheric conditions gradually become less suitable for the development of typhoons.
From that point of view, I think that the process of gradual weakening will begin after passing around Amami Oshima or just before that.
Q. In terms of time, is it an image that it will be about 915 hectopascals a little before 9 am on the 6th, and will continue until noon on the 6th or so?
(Person in charge of the Meteorological Agency's Forecasting Division)
A. I think it would be good if you could have an image of when you are entering the 6th, or from the night of the 5th to the middle of the 6th.
However, for example, when predicting the course of a typhoon, there are errors such as the forecast circle, and naturally there are also errors in the forecast of strength.
When you develop the most, on the contrary, I hope you understand that there is some error in the timing of its development and the timing of its debilitation.
Forecast of rainfall exceeding river capacity
Q. You mentioned hazard maps at the beginning and even mentioned the possibility of flooding a fairly wide area. Does this mean that the Japan Meteorological Agency has a strong sense of crisis?
(Ministry of Land, Infrastructure, Transport and Tourism Director Takamura)
A. The current expected rainfall may exceed the capacity of the river in the river development plan in some cases. We think.
For the time being, rainfall forecasts are coming in order, so it is written from the course of the typhoon that the first rains around Kagoshima and Miyazaki are now dangerous, but as we move northward, we will reach the northern part of Kyushu. Even comes out of danger.
Depending on the situation, rain and water vapor may come from the southern part of the area far away from the typhoon, so I think that it may be dangerous even in the remote area.
Q. It is said that there is a possibility that it will increase after that due to the forecast of rain. Specifically, considering the course of the typhoon, which areas are likely to accumulate more rainfall?
(Director Nakamoto, JMA)
A. There are some places where the south wind continues to enter even after the typhoon has passed, so I would like to see it in the future.
In addition, depending on the course of the typhoon, there are places where direct clouds of the typhoon will come out, but there are places where it will come out depending on the wind direction, so I think that the number of Kyushu regions will increase, but I am looking forward to everyone again while looking at the afternoon data and the latest data. Wants to convey information.
Q. Looking at your career path, it will increase in Kyushu, but should you consider other areas?
(Director Nakamoto, Japan Meteorological Agency)
A. Well, I think that it is better to consider the southern slope of the Pacific coast and the eastern slope.
Be even more alert in areas affected by heavy rain
Q. It's been a while since Typhoon No. 9 passed Nagasaki, but what's the point to watch out for another ten?
(Director Nakamoto, JMA)
A. I understand that there are various damages.
Before the weather changed, I said that it was up to 4 days, but I still have time, so I think that what I can do at this time is to take measures.
Q. It is expected to approach the southern part of Kyushu considerably, but in the southern part of Kyushu, the heavy rain in July caused a lot of damage.
So what would you call out to those who were affected by the disaster, or if similar heavy rains are expected?
(Chief Director Nakamoto of the Japan Meteorological Agency)
A. This time, there was heavy rain in July, and there were typhoons that passed through Kyushu, such as Nos. 8, 9 and 10, and No. 9 was Tsushima. There are places where the damage is spreading.
As for No. 10 as well, it is expected that there will be more rainfall in the southern part of Kyushu, so please request early evacuation and early measures.
I can only say this honestly, but I would like you to evacuate as soon as possible.
Therefore, we would like you to always keep in mind the information of the local government and act accordingly.
* Prediction of typhoon power, wind, and rain is at 11:00 am on the 4th.
Please check the latest information as it may change in the future.
