- Description
- Exceptionally high waves; small and medium-sized ships may be lost to view for long periods; the sea is completely covered with long white patches of foam; visibility is seriously affected.

- All routine operations suspended; structural survivability of even capital ships is at risk; air and surface operations impossible; storm survival is the only operational consideration.
