Weather Situation
A ridge of high pressure is expected to persist over the coast, directing east to northeasterly flow for much of the week. A weak trough is forecast to bring a brief southerly change on Wednesday to the south coast. Then, winds will turn fresh north to northeasterly later in the week as a trough extends to central parts of the coast, possibly deepening to a low pressure system off the coast on Saturday. Fresh southerly winds are forecast to develop along the coast later weekend in the wake of the low.
