The tide on Tuesday morning is set to occur at approximately 8:00 am local time at Carmarthen Bay Holiday Park.
This tide will coincide with tidal surge and moderate to large offshore waves.
Winds are forecast to be force 7 from a south-south-west direction.
Water levels are forecast to cause water to overtop defences on the most exposed parts of the park.
Although the conditions only indicate a marginal breach of the flood warning thresholds, chalets closest to these defences could be affected.
Conditions near the exposed defences are likely to be dangerous.
Conditions on Tuesday evening are expected to improve, though wave overtopping is still possible.
Unless there is a significant change in the forecast, this flood warning will be removed on Tuesday afternoon and the flood alert will remain in force for Tuesday evening and possibly Wednesday morning.
