The advice from the SES is to be prepared.

"There will be less total rain and less wind than last week but still it is likely to be windy and very wet," an Ulladulla SES spokesperson said.

"If you need emergency assistance from SES, including sandbags to divert water, call 132 500 and for life-threatening matters call 000.

"Our volunteer teams have been working every day since last week, we are here to help."

Last week the SES responded to an incredible number of jobs and stands ready to assist people in need once more.

Meanwhile, the forecast for Friday is for cloudy conditions with heavy showers, at times, with a fresh wind tending from the south west.

Saturday is predicted to be partly cloudy, with showers and a chance of a storm.

Sunday's prediction is for mostly cloudy cognition with a possible shower.

The SES offers some quick tips.
