As of 09 JST (00 UTC) on October 22, large, Very Strong Typhoon No. 30 (Champi) was moving westward over waters south of Okinawa. The typhoon has intensified over warm waters with sea-surface temperatures of 28°C or higher, and its central pressure has fallen to 915 hPa. It continues to have a storm-force wind area. The typhoon may approach Taiwan and coastal areas of China before turning northeast and moving toward southern South Korea and western Japan as it transitions into an extratropical cyclone.

Typhoon to turn north and move into the East China Sea

The typhoon has been moving westward, but is forecast to turn north around the edge of the Pacific high-pressure system. It is expected to pass near Japan’s Sakishima Islands on October 23 and move into waters north of Taiwan by October 24, while retaining a storm-force wind area. It is then forecast to weaken as it moves north across the East China Sea through October 25, before becoming an extratropical cyclone on October 26.

High alert urged for strong winds, heavy rain and high waves

The typhoon remains Very Strong, and storm-force winds may batter areas around it. Heavy rain is also possible in Japan’s Sakishima Islands and Taiwan, with total rainfall since the rain began potentially exceeding 500 mm in some locations. People should remain on high alert for rising rivers and flooding, landslides, and flooding in low-lying areas. Waves around the typhoon are forecast to reach 6–10 m, and coastal areas should also be on alert for high waves.
