The latest typhoon news on the morning of June 2nd said that as of 7:45 am local time, typhoon Jangmi was about 90km northwest of Amami city, Kagoshima prefecture.
Jangmi is moving north-northeast at a speed of 25 km/h, with a central pressure of 975 hectopascals. The storm has sustained winds near the center reaching about 108 km/h, with gusts up to about 144 km/h.
According to the Japan Meteorological Agency (JMA), Typhoon Jangmi is expected to move northeast and approach Kyushu, Shikoku, Kinki, Tokai and Kanto-Koshin regions until June 3.
The Japan Meteorological Agency has warned of strong winds, high waves, high tides, landslides, flooding in low-lying areas and rising or overflowing river levels in areas affected by Typhoon Jangmi.
Japanese weather forecasters also noted that strong active rain clouds related to Typhoon Jangmi will spread along the Pacific coast of Japan, from Kyushu to Kanto, leading to the risk of very heavy rain, which could quickly cause road flooding.
According to the Japan Meteorological Society, rainfall may be particularly intense on slopes facing southeast due to the influence of a cold air mass extending northeast of the storm.
In Kyushu, Typhoon Jangmi is expected to be closest to the southern areas in the afternoon of June 2. Routes most likely to be affected from about noon on June 2 to noon on June 3. Heavy rain may occur, especially in the south, while strong winds strong enough to overturn trucks may be recorded in some areas.
In Chugoku and Shikoku, continuous heavy rain is forecast from the night of June 2 to the morning of June 3, with Shikoku's Pacific side at risk of particularly severe heavy rain. Kinki and Tokai are also expected to have heavy rain and strong winds from the night of June 2 to the morning of June 3, with the possibility of traffic disruption during the morning rush hour of June 3 and lasting until the afternoon.
In the Kanto area, the storm is forecast to approach closest around noon on June 3. Rain and winds may strengthen from early morning, especially in the southern areas, causing roads to be affected from late morning and disruptions may last until June 4.
