Since Typhoon No. 6 moves slowly, there is a risk that it will cause storms in similar areas in the future. It is necessary to be extremely vigilant against disasters because the amount of rainfall will increase in places where it is already raining heavily. In addition, Typhoon No. 7 moves north while developing south of Kanto. Since there is a risk of affecting Honshu during the Obon holidays, prepare early.

Landslide warning information in southern Kyushu, impact lasts

Due to the slow-moving Typhoon No. 6, severe weather continues mainly in southern Kyushu and Amami.
By 1:30 pm on the 8th today, it is believed that about 90 mm of “furious rain” fell in the vicinity of the northern part of Yakushima Town, Kagoshima Prefecture.
In Tanegashima, Kagoshima Prefecture, a maximum instantaneous wind speed of 32.0m/s was recorded. (6:05 p.m. East-northeast wind)
In southern Kyushu and Amami, which are near typhoons, intermittent torrential rain falls. As of 6:00 p.m., Nishinoomote City, Nakatane Town, and Yakushima Town in Kagoshima Prefecture, Morotsuka Village, Misato Town, and Hinokage Town in Miyazaki Prefecture. “Earth and sand disaster warning information” is being announced. The danger of disasters is increasing, and it is a dangerous situation that requires evacuation.

In addition, the moist air around the typhoon is flowing in from the south, causing heavy rain even in remote areas.
The 24-hour rainfall exceeded 200 mm in Kochi and Tokushima prefectures, and reached 300.5 mm by 1:20 am in Yanase, Umaji Village, Kochi Prefecture, making it the heaviest rainfall of the year. Even on the Kii Peninsula, there are places where rainfall is increasing, mainly on the slopes on the southeastern side.

From Kyushu to the Pacific Ocean side of the Tokai, the ground has already loosened due to heavy rains.

In Kyushu, there is a risk of a “linear rain belt” occurring, which may exceed the amount of rainfall for a month in August.

Heavy rains are already being experienced in Kyushu, Amami, Shikoku and the Pacific Ocean side of the Tokai region, and heavy rains are expected in various places due to Typhoon No. 6, which is slow to move south of Kyushu.

First, active rain clouds are expected to continue in Kyushu, which is close to the typhoon.
A linear rain belt will occur in the Amami region and southern Kyushu from the night of the 9th tomorrow, and from the night of the 8th to the morning of the 10th in the northern Kyushu region, and the risk of heavy rain disasters may increase sharply. Regardless of the occurrence of a linear rain belt, it continues to rain, and the danger of disasters is likely to increase day by day, so please be extremely vigilant.

In addition, from western Japan to eastern Japan on the Pacific side, intermittent very heavy and heavy rain will continue, even in areas away from the typhoon.
Due to the slow speed of the typhoon, there is a risk that the total rainfall will greatly exceed the monthly rainfall in August, especially in areas on the southeastern slopes.

From around the 10th to the 12th, the latter half of this week, it is expected to approach the Ogasawara Islands with “strong” force accompanied by strong winds.
Due to the approach of the typhoon, very strong winds will blow in the Ogasawara Islands from the 10th to the 12th, and there is a possibility of warning-level heavy rain. It is necessary to be vigilant and careful of storms, high waves, and heavy rain.

After that, Typhoon No. 7 may approach the Izu Islands with a strong force until around the 13th.
Even in the Izu Islands, depending on the course and degree of development of the typhoon, there is a possibility of strong winds around the 13th, and from the 10th to the 13th there is a possibility of severe storms. Be careful of strong winds and high waves.

After that, the forecast circle is not widely set yet, but it is likely to move northward to the south of Kanto over the weekend, which may affect the weather during the Obon period. Please pay attention to future course and influence. Also, sea leisure requires caution and vigilance against high waves.
