Current Threat from Typhoon Surigae
On September 28, Typhoon Surigae moved near Okinawa Prefecture and the Amami islands, tracking northeast toward the Kanto region. The Japan Meteorological Agency (JMA) classified Surigae as a “very strong” typhoon, defined by maximum sustained winds of 85–105 knots (157–194 km/h). The U.S. military’s Joint Typhoon Warning Center (JTWC) later upgraded the system to a “super typhoon,” a category applied to storms with sustained winds exceeding 130 knots. Although the storm’s eye is not expected to make direct landfall on Okinawa, the JMA warned of high waves, violent squalls, and localized torrential rain that could affect the southern prefectures on Tuesday and Wednesday. Forecast models suggest Surigae will weaken to a severe tropical storm before reaching the Izu Islands and the Tokai-Kanto area later in the week, but residual wind speeds remain sufficient to topple telephone poles, snap trees, and disrupt travel.
Background: Recent Typhoon Dujuan
Just days earlier, Typhoon Dujuan struck the Kanto-Koshin region, killing at least 10 people in Chiba, Miyazaki and Kanagawa prefectures. The storm triggered hundreds of landslides, flooded agricultural lands, and broke water-level records earlier in the month. Thousands of households lost water service, with roughly 470 still without water as of Monday. The land ministry warned that Surigae could generate additional heavy-rain alerts, extending an already historic September precipitation streak.
Potential Impacts and Forecast
If Surigae’s remnants reach Kanto as a severe tropical storm, the region could face continued strong winds, heavy rain, and coastal swells that may exacerbate flood-control challenges still being addressed after Dujuan. The JMA notes that wind speeds over 140 km/h can topple utility poles and damage houses, raising concerns for neighborhoods still recovering from prior damage. Transportation networks, already strained by earlier road and rail shutdowns, could experience further disruptions.
Official Warnings and Responses
The JMA issued urgent advisories for Okinawa and the Kanto region, emphasizing the risk of massive coastal swells and localized downpours. Japan’s land ministry echoed these alerts, warning of possible heavy-rain warnings later in the week. Local authorities have begun pre-emptive measures, including securing vulnerable infrastructure and preparing emergency shelters for residents in flood-prone areas.
What Comes Next
Meteorological agencies will continue to monitor Surigae’s trajectory, issuing updates as the system approaches the main islands. Residents in Okinawa, the Izu Islands, and the broader Kanto metropolitan area are advised to stay alert to evolving forecasts and to follow guidance from local disaster-management offices.
