According to the latest typhoon news on the afternoon of June 1st from the Japan Meteorological Agency, Typhoon Jangmi will approach Okinawa closest on the night of June 1st and the Amami area on the morning of June 2nd, before moving northeast. After that, the typhoon will approach the Kyushu, Shikoku, Kinki, Tokai and Kanto-Koshin areas until June 3rd.
The Japan Meteorological Agency warned that affected areas may record strong gusts of wind, high waves, storm surges, landslides, flooding in low-lying areas, as well as the risk of rising or overflowing river levels.
As of 4 pm on June 1, the center of Typhoon Jangmi is about 90km south-southwest of Naha city and is moving north at a speed of 20 km/h. The center pressure is at 975 hPa. The sustained wind near the center of the typhoon reaches about 108 km/h, while gusts can reach 162 km/h.
The Japan Meteorological Society said that strong cloudy bands related to Typhoon Jangmi will spread along the Pacific coast from Kyushu to Kanto. This increases the risk of extremely heavy rains that could quickly cause flooding on roads.
Rainfall may be particularly heavy on southeastern mountain slopes due to the influence of a weather band extending northeast from the storm center.
In Kyushu, Typhoon Jangmi is forecast to approach the southern area in the afternoon of June 2. The road traffic system may be most heavily affected from around noon on June 2 to midday on June 3. Torrential rain may appear, especially in the southern area. Some places may also record winds strong enough to overturn trucks.
In the Chugoku and Shikoku regions, heavy rain is forecast to occur in waves from the night of June 2nd to the morning of June 3rd. The Pacific coastal area of Shikoku is at risk of recording particularly heavy rains.
Kinki and Tokai regions are also forecast to have heavy rain and strong winds from the night of June 2nd to June 3rd. Traffic may be disrupted in these areas during peak hours on the morning of June 3rd and last until the afternoon.
In the Kanto region, Typhoon Jangmi is forecast to approach closest around noon on June 3. Rain and winds may strengthen from the morning of June 3, especially in the southern areas of this region.
Japanese Chief Cabinet Secretary Minoru Kihara informed that the government has established an information coordination office at the Cabinet Disaster Management Center and is coordinating with local authorities to share weather information as well as evacuate residents.
He called on people in areas expected to be affected to closely monitor evacuation notices and proactively implement safety measures.
According to Japan's new 5-level disaster warning system that has just been applied since May 29, people in dangerous areas need to evacuate when functional agencies issue a heavy rain warning equivalent to level 4.
