For people in parts of Central Tablelands and Central West Slopes and Plains Forecast Districts.

Issued at 1:27 pm Friday, 26 November 2021.

Slow-moving, heavy thunderstorms are developing in central parts of the state.

Weather Situation: An upper low sits over the centre of the state, dragging down very humid air from its northeast. An associated surface trough will continue to trigger thunderstorms nearby into the afternoon, some of which will produce heavy rainfall.

Slow-moving severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding in the warning area over the next several hours. Locations which may be affected include Dubbo, Parkes, Wellington, Condobolin, Gilgandra and Peak Hill.

The State Emergency Service advises that people should:
* 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 as well.
* 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.
