The focus of the severe weather now shifts further south. A low pressure system developing off the northern coast of NSW is expected to strengthen into an East Coast Low during the next 24-48 hours and move towards central NSW.

The animation below shows the predicted movement of this developing East Coast Low, and its associated rainfall, according to Australia’s ACCESS-G forecast model.

Heavy rain, thunderstorms, damaging winds, abnormally high tides and damaging surf are likely to develop over parts of central and southern NSW as the East Coast Low moves further west in the coming days.

At this stage, heavy rain, storms and damaging winds are expected to affect the coast and adjacent ranges from about Newcastle down to Bega from Tuesday night into Wednesday and possibly Thursday. Damaging surf and abnormally high tides could also affect the coastal strip from the South Coast up to the lower Mid North Coast from Tuesday night into Wednesday. Severe weather warnings have been issued for these areas.

However, exactly where this severe weather strikes over the next 48 hours will depend on the strength and location of the East Coast Low. If this system’s forecast track changes, the areas covered by thede our clients with detailed rain, wind and thunderstorm forecasting for  severe weather warning may also change.
