Weather Situation
A high pressure ridge is extending across the coastal waters, directing northeasterly winds along much of the coast. Northerly winds will strengthen today as a high pressure system within the ridge drifts across the state and move into the Tasman Sea. Later, a cold front and its associated trough are forecast to move across the coastal waters from Friday through early Saturday, bringing a fresh and gusty southerly wind change in its wake.
