Typhoon Dolphin passed south of Chichijima Island in Japan’s Ogasawara chain on Tuesday, bringing heavy rain and dangerous ocean swells [1].
The storm's intensity threatens critical maritime infrastructure and coastal safety in the remote island chain, specifically impacting areas like Futami Port [1].
The Japan Meteorological Agency has classified the system as a "very strong" typhoon [1]. It marks the 13th named storm of the Pacific season [1].
Weather data indicates the storm is moving westward at a forward speed of 20 km/h [1]. At its peak, the cyclone produced maximum sustained winds of 216 km/h, or 134 mph [1]. These wind speeds have contributed to volatile sea conditions, with ocean swells reaching heights of up to 11 meters [1].
Local authorities continue to monitor the system as it moves through the western Pacific. The combination of heavy precipitation and massive swells creates significant risks for shipping and coastal settlements, particularly in the Ogasawara chain where geography limits evacuation options [1].
Emergency services in the region remain on alert as the storm progresses. The impact on Futami Port remains a primary concern for regional logistics and safety [1].
“Maximum sustained winds of 216 km/h”
The classification of Typhoon Dolphin as a 'very strong' system by the Japan Meteorological Agency underscores the volatility of the current Pacific storm season. Because the Ogasawara Islands are remote, the arrival of 11-meter swells and high-velocity winds can isolate communities and disrupt essential maritime supply chains, necessitating high-level readiness for coastal infrastructure like Futami Port.
