South Korean port authorities suspended 42 of 99 scheduled ship routes Tuesday due to strong winds from the remnants of Typhoon Bob [1].

The disruptions affect critical maritime corridors and passenger travel to several islands, highlighting the vulnerability of the west coast's transport infrastructure to seasonal storm systems.

Wind gusts reached approximately 55 km/h [1]. These conditions prompted maritime wind warnings across the region, which led to the suspension of vessel movements to ensure passenger safety.

Incheon Port saw the most significant impact, with 13 of its 15 routes closed [1]. Similarly, Boryeong Port in the central west coast fully closed six routes [2]. The closures specifically impacted travel to Yeonpyeong and Baengnyeong islands [1].

Beyond the route closures, 50 passenger vessels were held in port [1]. This figure excludes ships that were already undergoing maintenance at the time of the storm [1].

"Of the 99 routes planned for today, 42 were blocked due to the influence of strong winds," said reporter Lim Ye-jin of YTN News [1].

Local authorities monitored the situation as the remnants of the typhoon moved through the area. The forecast indicated that strong winds and rain would persist across most regions of the country [1].

"Excluding vessels receiving maintenance, 50 passenger ships were stranded by the strong winds," Lim said [1].

“42 of 99 scheduled ship routes were placed under a strong‑wind warning and suspended”

The suspension of nearly half of the scheduled routes demonstrates the high sensitivity of South Korean coastal transit to wind speeds as low as 55 km/h. Because these ports serve as primary lifelines for remote islands like Yeonpyeong and Baengnyeong, such weather-driven closures create immediate isolation for residents and disrupt regional logistics.
