Typhoon 18 is approaching the Daito Islands and is expected to hit the Okinawa and Amami regions between Tuesday night and Wednesday morning [1, 2, 3].

The storm arrives during the peak summer holiday season, threatening travel infrastructure and posing significant safety risks to residents and tourists in southern Japan.

Weather officials said the typhoon is maintaining strong intensity as it moves north [1, 2]. In the Amami region, maximum instantaneous wind speeds are forecast to reach 60 m/s [2]. Expected rainfall in the same region could reach 250 mm by noon Wednesday [1].

The storm has already begun impacting the Daito Islands. At 3:25 a.m., Kitadaito Island recorded a maximum instantaneous wind speed of 42.2 m/s [3].

Transportation networks are facing significant disruptions as the storm nears the coast. A total of 279 flights have been canceled [2]. Local authorities said they are monitoring the situation as the system moves toward Okinawa Island and the Amami region [1, 2, 3].

Residents in the path of the storm are advised to secure loose outdoor items and follow evacuation orders. The combination of high wind speeds and heavy precipitation increases the risk of flooding, and landslides in mountainous areas of the Amami region [1].

Forecasts indicate the system will maintain its strength through its closest approach to the main islands [1, 2]. Officials said they continue to track the trajectory to determine if further travel disruptions will occur across the archipelago [2].

Maximum instantaneous wind speeds are forecast to reach 60 m/s

The timing of Typhoon 18 is particularly disruptive because it coincides with the summer holiday peak. The high volume of tourists in Okinawa and Amami, combined with the cancellation of nearly 300 flights, creates a logistical bottleneck that may leave thousands of travelers stranded. Furthermore, wind speeds of 60 m/s are capable of causing structural damage and widespread power outages, necessitating a high level of emergency preparedness in these island chains.
