Please be aware
Wind and wave forecasts are averages. Wind gusts can be 40 per cent stronger than the forecast, and stronger still in squalls and thunderstorms. Maximum waves can be twice the forecast height.
A high pressure system well south of the state will extend a ridge coastal waters until a trough begins to enter in the west early Thursday. This trough and a weak embedded low pressure system will sweep across waters on Thursday with a weak high pressure system developing in the Bight on Friday. This high will move eastwards, making way for cold front moving into the west late Saturday.
