Weather Situation
A cold front and its associated trough are forecast to cross the coastal waters on Saturday, with a west to southwesterly wind change in its wake. This system will be followed by a weaker cold front brushing the south during the weekend before another stronger cold front crosses the coast on Monday, bringing fresh gusty southerly winds after its passage. Then, southerly winds will gradually ease mid next week as a strong high pressure system moves over the Bight and extends a ridge across the state.
