The NSW State Emergency Service is urging communities across southeastern NSW to prepare for the impacts of heavy rain and damaging winds as potential severe thunderstorms are forecast over the coming days and into the weekend.
Forecasts indicate slow and steady rainfall across much of the southeastern half of the state, which may combine with thunderstorms to produce isolated heavy falls.
The main risk expected from this weather is flash flooding, particularly in low-lying and flood-prone areas.
From Thursday and into the weekend, rain is expected to become more widespread across the Illawarra, Shoalhaven and South Coast.
With rainfall expected to fall over several days, creeks and rivers may rise quickly, and water may cover roads in some areas.
