Bydd cynlluniau wrth gefn a roddwyd ar waith i ddiogelu porthladd a chymuned Caergybi yn cael eu haddasu'n raddol dros y mis nesaf, yn dilyn cyfnod adolygu a chwblhau safle stacio ar Barc Cybi.
Contingency plans put in place to protect the port and community of Holyhead will be modified gradually over the next month, following a period of review and the completion of a stacking site on Parc Cybi.
