Event

Localized evacuation orders were issued in parts of Okinawa prefecture on Monday, August 31, as Typhoon Maysak approaches. Households in parts of Naha City and Okinawa City have been ordered to move to more sturdy structures ahead of wind gusts of up to 216kmh (134mph), which are expected to cause some houses to collapse. At least 250 flights operating across the prefecture were canceled on Monday, and terminal buildings at Naha Airport (OKA) will remain closed until Tuesday, September 1. Forecasters have warned of flooding in low-lying areas and mudslides with rainfall expected to reach up to 40cm (15in) in some parts of Okinawa by Tuesday.

Typhoon Maysak is currently located 129km (80mi) southwest of Okinawa and is currently moving in a northerly direction towards the Korean Peninsula. Maysak is currently sustaining winds of up to 204kmh (127mph). Maysak is expected to strengthen further as it moves further north and is currently forecast to make landfall in the vicinity of Yeosu-Si (South Korea) on Wednesday, September 2.

Context

The typhoon season lasts from May to October, whilst most storm systems form between July and September. In general, storms can bring heavy downpours and strong winds as well as trigger storm surges which threaten human populations and infrastructure. Secondary effects include riverine floods and landslides, both of which can result in human casualties and mass evacuations, as well as travel and service disruptions. Although storm systems usually affect southern Japan, other parts of the country are also vulnerable to these hazards.

Advice

Those in the affected areas are advised to monitor local weather reports, avoid areas directly affected by flooding, confirm road conditions before setting out, and adhere to instructions issued by local authorities.
