Weather Situation
South to southeasterly winds are gradually turning east to northeast as a high pressure ridge over the coastal waters is weakening. Then a trough will brush the coastal waters midweek, bringing a surge of fresh southerly winds along the coast, and this will be followed by another ridge extending from a high passing to the south of the state.
