Heavy rainfall which may lead to flash flooding is forecast for the Hunter, Sydney Metropolitan, Illawarra, South Coast, and parts of the Central Tablelands districts.
Six-hourly rainfall totals between 70 to 120 mm are possible. Heavy rainfall areas will gradually contract from the north during the day, with the peak of the rainfall most likely about the Sydney Metropolitan and Illawarra districts.
Locally intense rainfall leading to dangerous and life-threatening flash flooding is possible with thunderstorms, six-hourly rainfall totals in excess of 150 mm are possible.
Damaging wind gusts with peak gusts in excess of 90 km/h are possible over the Sydney Metropolitan, South Coast, Illawarra and Southern Tablelands districts. The risk of damaging wind gusts is expected to persist into Wednesday.
Damaging winds averaging 60 to 80 km/h with peak gusts of around 110 km/h are possible over the coastal fringes of the Illawarra and Sydney Metropolitan districts this evening.
Severe thunderstorm warnings are being issued when very dangerous thunderstorms with intense rainfall are detected.
Heavy rainfall increases the potential for landslides and debris across roads.
The SES advises that people should:
- Move vehicles under cover or away from trees.
- Secure or put away loose items around your house, yard and balcony.
- Keep at least 8 metres away from fallen power lines or objects that may be energised, such as fences.
- Trees that have been damaged by fire are likely to be more unstable and more likely to fall.
- Report fallen power lines to either Ausgrid (131 388), Endeavour Energy (131 003), Essential Energy (132 080) or Evoenergy (131 093) as shown on your power bill.
- Don't drive, ride or walk through flood water.
- Keep clear of creeks and storm drains.
- If you are trapped by flash flooding, seek refuge in the highest available place and ring 000 if you need rescue.
- For emergency help in floods and storms, ring your local SES Unit on 132 500
