New South Wales

Synoptic Situation: A light pressure pattern lies across the region in the wake of ex-Tropical Cyclone Uesi, with a high pressure system south of the continent slowly moving southeast. Southeasterly winds are expected to tend northeasterly by Monday evening ahead of the next cold front, which is forecast to bring a southerly change to New South Wales waters in the middle of the week. A low pressure system may develop near the southeast of the continent on Wednesday in response to the front, possibly strengthening winds and developing hazardous surf conditions, before rapidly moving away to the east.
Wind and wave forecasts are averages. Wind gusts can be 40 per cent stronger than the forecast, and stronger still in squalls and thunderstorms. Maximum waves can be twice the forecast height.
