Weather Situation
A high pressure system over the southeastern Tasman Sea is extending a ridge towards far northeastern New South Wales maintaining a northeasterly airstream over Sydney Waters. A cold front and its associated trough are forecast to enter the far south coast later today and cross Sydney Waters early Thursday morning with strong and gusty southerly winds in its wake. Fresh to strong south to southeasterly winds and may remain during the later part of the week through the weekend as a low pressure system develops off the Mid North Coast.
