Typhoon No. 9 is moving toward Okinawa, bringing heavy rain and gale-force winds to the region this weekend [1, 2].
The storm's intensity poses a significant threat to infrastructure and transportation in the Yaeyama islands, where the closest approach is expected between Friday and Saturday [1, 3].
Classified as large and very strong, the typhoon is traveling north-northwest at approximately 20 km/h [1]. Local authorities have reported severe weather conditions already impacting the islands. At Ishigaki Airport, wind speeds reached 26.2 m/s [1]. In Ohara on Iriomote island, maximum gusts of 26.5 m/s were recorded just after noon on Friday [1].
Transportation networks have been severely disrupted by the storm's arrival. All scheduled flights and ferries to Ishigaki Island have been cancelled [1]. Residents and travelers are facing a total shutdown of these primary transit links as the storm maintains its strength.
Rainfall is expected to be heavy across the prefecture. Yawara Yano, a forecaster with the Japan Meteorological Agency's Forecast Division, said the expected precipitation for the Okinawa region is 200 mm over the 24-hour period from July 10 to July 11 [3].
Beyond the immediate wind and rain threats, the region is also managing heat warnings. The combination of unstable weather and high temperatures continues to affect the islands as the typhoon moves closer to the coast [1, 2].
Authorities continue to monitor the system as it approaches the Yaeyama islands, including Miyako, Ishigaki, and the surrounding seas [1, 2].
“All scheduled flights and ferries to Ishigaki Island have been cancelled.”
The total cancellation of transit to Ishigaki Island underscores the severity of Typhoon No. 9's wind speeds, which are currently exceeding safe operational limits for aviation and maritime travel. With 200 mm of rain forecast in a single day, the region faces a high risk of flash flooding and landslides, complicating emergency response efforts during the storm's closest approach.
