Typhoon 17 Approaches: Strong Winds and High Waves Expected in Chiba Prefecture

Typhoon No. 17 Approaching Chiba Prefecture Soon – Be Cautious of Very Strong Winds and High Waves

Typhoon No. 17 is approaching the Kanto region, and Chiba Prefecture will soon enter the strong wind area of the typhoon. There is a possibility of very strong winds in Chiba and Ibaraki Prefectures. Additionally, caution is advised due to high waves at sea.

Chiba Prefecture About to Enter Strong Wind Area

As of 9 AM, Typhoon No. 17 is moving north at a speed of 35 km/h southeast of Hachijo Island. The strong wind area (winds of 15 meters per second or more) is expected to soon reach Chiba Prefecture. A maximum instantaneous wind speed of 17.3 meters was observed around 7 AM on Miyake Island in the Izu Islands, which is close to the typhoon. There are likely to be areas in Chiba and Ibaraki Prefectures where “very strong winds” will bend slender tree trunks.

Moreover, rain clouds around the typhoon are already affecting Chiba Prefecture, and some places are experiencing rain. There were also temporary rain showers in central Tokyo, and variable weather is expected to continue.

Caution for Strong Winds and Thunderstorms During Your Commute Home

Typhoon No. 17 is expected to continue moving north and reach its closest point to the Kanto region from noon to early evening. Although there is no threat of landfall, rain clouds around the typhoon will affect coastal areas and winds will strengthen. There is a risk of transportation disruptions during your commute home. Additionally, waves at sea are expected to rise, and some areas may experience rough seas.

Afterwards, the typhoon is projected to change its course to the east and transition into a temperate low-pressure system east of Hokkaido by tomorrow morning (2nd). There will be rain and strong winds in the Pacific side of Tohoku and eastern Hokkaido, with high waves expected at sea.

What Are Very Strong Winds?

Very strong winds refer to winds with an average wind speed of 20 m/s or more but less than 30 m/s. In terms of speed, that is approximately 70 km/h to 110 km/h, comparable to the speed of vehicles on the highway. Such winds are strong enough that one may not be able to stand without holding onto something, and driving at normal speed becomes difficult. When these winds occur, there is a risk that roof tiles and signs may fall or get blown away. (Note that instantaneous wind speeds can often be 1.5 times the average wind speed and may sometimes exceed three times.)

There is a risk of injury from flying debris, so outdoor activities should be approached with caution. When very strong winds are expected, it is advisable to bring potted plants and other lightweight items indoors.
