NSW coastal communities have been warned for the potential for flash flooding after rain inundated parts of the state, with the state emergency service receiving 133 pleas for help.
While the rain is expected to ease by Sunday afternoon, the Bureau of Meteorology said six-hourly totals of 80 to 120mms were possible, plus peak wind gusts of about 90km/h.
The State Emergency Service warned residents to remain vigilant and said the severe winds could “bring down trees, relocate garden furniture and move tiles on rooves”.
On Sunday morning, NSW SES State Duty Commander, Assistant Commissioner Nicole Hogan warned that the threat from the weather system “had not passed”.
“We are still seeing rainfall and while it will ease during the day, gale winds have been forecast for the Illawarra, Batemans and Eden Coastal areas.”
However conditions appeared to be improving, despite the possibility for further heavy rain.
Despite the Bureau issuing a severe weather warning for heavy rainfall and damaging winds on Sunday, the warning was cancelled about 9.30am.
“A low pressure system just offshore of the Illawarra coast is forecast to shift south today, with a further easing trend expected during the afternoon and evening,” they said.
“The immediate threat of severe weather has passed, but the situation will continue to be monitored.
“Local heavy rainfall and damaging winds remain a possibility over coastal areas during the day, and a severe thunderstorm warning will be issued if necessary.”
This comes as heavy but short localised downpours lashed several locations on Saturday, with Ulladulla recording 89mm of rain from 9am Saturday to 6am Sunday. 24-hour totals in Jervis Bay, Point Perpendicular, Currarong and Greenwell Point near Nowra all surpassed 100mm.
A damaging surf warning for “rough seas” was also issued for Norkfolk Island in the South Pacific Ocean at about 4am on Sunday, however conditions are expected to ease throughout the morning.
Residents have also been urged to avoid flood waters, take care on wet roads and secure loose items on their properties.
From about noon on Saturday, the SES asked people to collect sand bags, and consider cleaning their drains to prepare for the oncoming rain.
“People should secure or move items which could be blown away, such as trampolines, and beware of parking cars under trees, and remove branches near buildings,” said Ms Hogan.
Despite the wet weather in the south, the forecast for Sydney remains mild.
While the Bureau has forecast the chance for a thunderstorm, the city is only forecast to receive 1 to 5mm of rain, with a slight chance of showers after sunrise.
Elsewhere in the state, partly cloudy skies are expected to give way to sunny conditions, with a max of 26C in Brisbane, with a sunny day forecast for Melbourne, with tops of 17C.
The nation’s capital will likely receive 8 to 25mm of rain, however conditions are expected to ease in the eventing.
