Typhoon No. 14 is expected to stagnate in the East China Sea and move eastward after the 16th, and may approach western and eastern Japan over the weekend.
Due to the effects of typhoons and fronts, the amount of rainfall in Miyazaki Prefecture has already reached 350 mm, and there is a risk of heavy rainfall over the weekend, especially in western Japan.
This week, we need to be wary of long rains caused by "fronts + typhoons".
Typhoon No. 14 Is it approaching western and eastern Japan over the weekend?
According to the Japan Meteorological Agency, Typhoon No. 14 in the East China Sea is no longer a strong force and is expected to stagnate over the 15th.
It is expected to start moving eastward around the 16th, then proceed to the Sea of Japan and change to an extratropical cyclone, and will approach western and eastern Japan over the weekend.
When changing to an extratropical cyclone, strong winds blow not only in the center but also in a wide range, so caution is required.
"Front + typhoon" Be wary of long rains
On the other hand, even if you are away from the typhoon, you need to be wary of long rains this week, especially in western Japan.
Due to the warm and moist air around the typhoon flowing from Kyushu to the front extending to the south of Japan, it is raining intermittently in southern Kyushu.
In Miyazaki Prefecture, it rained extremely heavily from the night of the 13th to the early morning
of the 14th. It has become the most since I started.
After that, it rained intermittently, and the rainfall from the beginning of the rain on the 13th to 5 pm on the 14th was 350 mm, which is close to 90% of the average month of September in just one day.
Since the positions of the typhoon and the front are almost the same until the 15th, it will rain intermittently in western Japan, and then the rain clouds of the typhoon itself will cause further rainfall.
From now on, from the dawn of the 15th, the atmospheric conditions will become unstable mainly in Kyushu and Shikoku, and there is a risk of extremely heavy rain locally, so it is necessary to pay sufficient attention to sediment-related disasters and flooding of low land.
Be prepared for the risk of a disaster
In addition to the rain that preceded the approach of the typhoon like this time, if the rain clouds of the main body are applied, the amount of rainfall will increase sharply, and the risk of disaster may increase at once.
Understand the danger of disasters in the area from the hazard map of the local government in advance, and move people who take time to evacuate, such as the elderly and people with disabilities, to a safe place as soon as possible before the rain or wind intensifies. I am relieved. Especially in Kyushu, where it is already heavy rain, it may rain suddenly at night and lead to a disaster, so please rest at home away from rivers and slopes just in case.
In the past, there have been cases where heavy rains and extremely heavy rains have not been observed, but the amount of rainfall has gradually increased due to long rains, causing sediment-related disasters. Keep an eye out for information from local weather stations and local governments because it is not raining, and you can evacuate early by talking to local people or calling family members living away. Let's give a boost.
Also, depending on the course of the typhoon, heavy rain may occur not only in western Japan but also in eastern and northern Japan, so be careful about the latest weather information.
