The NSW South Coast is gearing up for another weekend of wild weather, with flooding expected in areas inundated only days ago.
A low pressure system tracking from NSW’s northwest to its southeast is expected to bring heavy rainfall, strong winds and severe thunderstorm to areas in its path.
The Bureau of Meteorology has issued flood watch warnings for the Shoalhaven, St Georges Basin, Bega, Queanbeyan and Snowy River areas from Saturday.
Many of those areas were impacted by heavy rainfall last week, but NSW BOM’s flood manager Justin Robinson says this weekend’s rain is likely to cause even more havoc.
Heavier rainfall is expected, and the catchment is already soaked so will absorb less of it.
“We’re talking flood levels more at that moderate to major level, rather than the minor flood that … we saw last week,” he told reporters on Friday.
“When you’re looking at moderate to major levels, that’s when major roads start getting impacted.
“It’s also when you see properties impacted and the SES may need to instigate some evacuations of those homes.”
Bega is expected to record the heaviest falls at 300 millimetres.
SES Assistant Commissioner Greg Lynch says the group is prepared for evacuations, but the best thing people can do to protect themselves is stay out of floodwaters.
“On our last occasion we rescued over 30 people from floodwaters. That is putting themselves at risk, and also putting at risk those that have to go and rescue them.”
The SES is in particular warning residents of the St Georges Basin, where more than 40 homes were impacted last week, to prepare for this weekend’s drenching.
Mr Lynch is asking residents in flood watch areas to have evacuation plans ready.
Conditions are expected to ease by Monday.
Lighter rainfall is expected across other parts of the state over the weekend, with Sydney likely to receive 10 millimetres.
Meanwhile, severe thunderstorms are expected in the state’s north, and significant snowfall in the alpine regions.
