Typhoon No. 12 has changed course from the east earlier than originally expected, and is expected to pass slightly off the Kanto coast. Areas where heavy rains are a concern are expected to shrink as typhoons pass. However, the wind will be stronger when you get closer, so you need to be vigilant.
As it moves away, the maximum wind speed near the center is expected to remain at 25 m / s even as it approaches the Kanto region.
▼ Typhoon No. 12 Wednesday September 23, 9:00
Area of existence Approximately 280 km southwest of Hachijojima
Move north-northeast 20 km / h
Central pressure 975 hPa
Maximum wind speed 30 m / s (near center)
Maximum instantaneous wind speed 45 m / s
As the typhoon passes, most of the developed rain clouds pass over the sea and the expected rain is decreasing. Even so, due to the influence of the autumn rain front, it can reach around 100mm in a wide area of Kanto, and around 200mm in many places such as the Izu Islands, Kanto and the coastal areas of southern Tohoku.
It can get a lot of rain in a short period of time, so be careful around roads and small and medium rivers.
As of Thursday 24, the wind will intensify on the Pacific side from Kanto to Tohoku, and is expected to momentarily exceed 20 m / s in a wide range and exceed 25 m / s in the coastal area. Although the risk of heavy rain has decreased, the effects of high winds may increase. When a typhoon is approaching, you need to pay attention to flying objects due to high winds, disruption of transportation schedules such as railways, and high waves in coastal areas.
Also, even after the typhoon has switched to a temperate low pressure, there is a risk of a storm on the Pacific side of northern Japan on Friday the 25th, so we cannot be vigilant.
Typhoon No. 12’s name “Dolphin” is a name proposed by Hong Kong, and is derived from one of Hong Kong’s representative animals, “Shiroka”.
