The NSW State Emergency Service (SES) is urging communities across south eastern 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 south eastern 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.
Thunderstorms are expected from today across parts of the South Coast, Illawarra, Sydney and Hunter, with some storms bringing 30-60 mm of rain an hour, gusty winds exceeding 90 km/h and large hail.
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.
NSW SES State Duty Commander Dallas Burnes said while rainfall totals may build gradually, conditions could change quickly, particularly during localised intense thunderstorms.
“Even moderate rain over several days can cause problems, especially when it falls on already wet ground,” Chief Superintendent Burnes said.
“We are working closely with the Bureau of Meteorology to monitor this system and our members across south eastern NSW have been briefed and are ready to respond.”
Chief Superintendent Burnes urged people to prepare early and be mindful of increased risks these school holidays.
“We ask people to be vigilant if camping near creeks and rivers and to make sure you have appropriate equipment as it might be raining for up to a week in some areas. If water levels begin to rise, move to higher ground immediately.”
Ahead of the rainfall people are encouraged to prepare their homes by clearing gutters and drains, securing loose outdoor items and parking vehicles away from trees or areas known to flood.
“Heavy rain is possible and that means roads can flood quickly. A flooded road is unsafe to drive on - we ask you to stop, turn around and find another route,” Chief Superintendent Burnes said.
The NSW SES encourages everyone to stay informed by downloading the Hazards Near Me app and setting a watch zone for their local area to receive the latest warnings and advice.
If you need assistance during storms or flooding, call the NSW SES on 132 500. In a life-threatening emergency, always call Triple Zero (000).
