'Heavy rainfall, flash flooding': severe storm warning for the Hunter (2025)

SEVERE thunderstorms are forecast to hit parts of the Hunter on Tuesday night.

The Bureau of Meteorology issued a warning shortly before 4.30pm that "severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding over the next several hours".

The warning covered parts of the Hunter, Metropolitan and Central Tablelands districts.

It follows heavy rain over the weekend, with overflow visible off the coast of Newcastle as swollen rivers rush into the ocean.

The NSW State Emergency Service had urged residents in Dungog, Clarence Town and Seaham to monitor conditions as river levels began to drop.

More rain, however, is expected in the days ahead.

The Bureau of Meteorology predicts showers in Newcastle and across much of the Hunter until Monday, albeit with only a few millimetres of rain expected daily.

The State Emergency Service advises that people bracing for storms should:

* Move your car 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.

* 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.

* Trees that have been damaged by fire are likely to be more unstable and more likely to fall.

* Keep clear of creeks and storm drains.

* Don't walk, ride your bike or drive through flood water.

* If you are trapped by flash flooding, seek refuge in the highest available place and ring 000 if you need rescue.

* Be aware that run-off from rainfall in fire-affected areas may behave differently and be more rapid. It may also contain debris such as ash, soil, trees and rocks.

* After bushfires, heavy rain and the loss of foliage can make the ground soft and heavy, leading to a greater chance of landslides.

* Unplug computers and appliances.

* Avoid using the phone during the storm.

* Stay indoors, away from windows, and keep children and pets indoors.

* Stay vigilant and monitor conditions. Note that the landscape may have changed following bushfires.

* For emergency help in floods and storms, ring the SES (NSW and ACT) on 132 500.
