A weak front will reinforce onshore winds Monday and Tuesday before winds trend southerly then offshore ahead of an approaching cold front on Wednesday. Showers and storms are expected along the second cold front as it pushes across the waters Thursday. Strong northwesterly winds will trail behind this front and persist into next weekend.
