Typhoon 13 is moving west toward Okinawa and southern Kyushu, bringing record-breaking winds and heavy rainfall through Aug. 8 [1].
The storm's intensity poses a severe risk of landslides and flooding, particularly in areas already vulnerable to geological instability. This event is critical because it threatens both major transportation hubs and regions still recovering from previous disasters.
Forecasters expect maximum instantaneous wind speeds of 55 m/s in Okinawa and the Amami Islands [1]. Total rainfall is projected to reach 200 mm by the morning of Aug. 8 across Okinawa and southern Kyushu [1]. Meteorologists said that the storm could trigger the formation of linear precipitation zones, which often lead to extreme, localized flooding [1].
Transportation has been severely disrupted. Naha Airport remained closed for the full day on Friday [1]. Japan Airlines cancelled 221 flights and All Nippon Airways cancelled 240 flights, impacting approximately 75,000 passengers [1].
The storm's reach extends to the Kumamoto region, which is still recovering from previous earthquake damage. This area has entered a strong-wind zone, and officials expect localized heavy rain reaching 20 mm per hour [1].
"Typhoon 13 requires strict vigilance against record-breaking storms and long periods of heavy rain," FNN said [2].
Authorities are urging residents in the Amami Islands, Kagoshima, and southern Kyushu to prepare for potential evacuations as the large and powerful system maintains its strength while moving west [1].
“Maximum instantaneous wind speeds of 55 m/s [1]”
The convergence of a high-intensity typhoon with a region already weakened by seismic activity in Kumamoto creates a compounding disaster risk. When heavy rainfall hits earthquake-damaged terrain, the likelihood of landslides increases significantly, potentially turning a weather event into a humanitarian crisis in specific disaster-hit zones.
