Flood Watch Information
Published on 28 July 2020
Weather Warnings
The Bureau of Meteorology have advised that a low-pressure system that formed off the southern Queensland coast is crossing over the South Coast. Damaging wind gusts and wind-driven large sea waves have developed along the southern parts of the coast. The rain rate should ease from this afternoon, although steady rainfall will still continue. Weather warnings have been issued as follows:
A moderate flood warning has been issued for St Georges Basin. Evacuations have occurred in Sussex Inlet and moderate flooding is expected this afternoon. No flood warning from the BoM has been issued for Shoalhaven River at the present time.
The following tables summarise current water levels and rainfall (at 8:39pm today) in key Council managed lake and river entrances. Flooding is occurring in parts of the Shoalhaven primarily due to catchment runoff and prevailing swell. Evacuations have occurred overnight in Sussex Inlet and moderate flooding is expected this afternoon in Sussex Inlet and other villages surrounding St Georges Basin.
