| Discussion: Rough seas are expected to start from the south coast after midnight, and spread to the extreme north coast between early and mid-morning. The waves will then start subsiding from the south towards late afternoon. |
| Impact: Localised damage to coastal infrastructure and localised disruptions to beachfront activities is possible. Difficulty in navigation is also possible ( e.g. small vessels in short period, steep waves). Small vessels may be at risk of taking on water and capsizing in a locality. |
| Instruction: Avoid beachfront activities like swimming or shore/rock angling. Small vessels should avoid going out to sea if possible. Attentively listen to the radio or watch television for any updates and look out for any other updates from the various social media platforms. |
