What is Risk Analysis in the Context of Environment Events
Environmental event risk analysis assesses the potential effects of high winds on transportation, maritime activity, infrastructure and outdoor operations. Coastal and island locations can face additional disruption due to strong winds combined with rough seas.
Known Hotspots and Sensitive Areas
High Impact
- Yeosu and southern coastal areas: Strong wind advisory in effect.
- Geomundo and Chodo: Exposed island locations under the advisory.
- Wando Yeoseodo and Gohungnambu: Strong winds may affect coastal activities.
- Geoje: Strong wind advisory affecting the southern coastal area.
- Jeju: Advisories cover parts of the island, including eastern and central/elevated areas.
Medium Impact
- Southern coastal waters: Marine weather advisories are in effect across parts of the South Sea.
- Waters surrounding Jeju: Strong winds and high waves may affect vessels and ferry operations.
Low Impact
- Inland areas outside the active advisory zones are expected to face comparatively lower direct exposure to the strongest winds.
Impact on Transportation and Services
Strong winds and high waves may disrupt ferry and maritime operations, particularly around exposed islands and southern coastal waters. Outdoor operations may also require additional precautions where gusts are strong enough to affect temporary structures, equipment or exposed infrastructure.
Recommended Actions
- Monitor KMA weather and marine advisories before travelling through affected areas.
- Check ferry and coastal transport schedules before departure.
- Avoid unnecessary maritime activity while strong-wind and high-wave advisories remain active.
- Secure temporary structures and outdoor equipment in exposed locations.
- Businesses operating along the southern coast should monitor conditions and prepare for potential weather-related delays.
Emergency Contacts
