Weather Situation: A humid easterly airstream is feeding into a pair of low-pressure troughs; one located offshore and another inland. This pattern is bringing unsettled weather across NSW resulting in localised heavy rainfall with thunderstorm activity this evening, extending into the overnight period.

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 Lismore, Grafton, Coffs Harbour, Armidale, Tenterfield, Tamworth, Gunnedah, Moree, Narrabri, Walgett, Dorrigo and Lightning Ridge.

Severe thunderstorms are no longer occurring in the Central Tablelands district and the warning for this district is CANCELLED.

- Delungra (95km ESE of Moree) recorded 60mm in 60min to 6:00pm.
- Moppy Lookout (at Barrington Tops) recorded 39.2mm in 60min to 6:45pm.

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.
