For people in parts of North West Slopes and Plains, Northern Tablelands, Mid North Coast and Central West Slopes and Plains Forecast Districts.

Issued at 7:01 am Sunday, 1 November 2026.

Severe thunderstorms developed in the north of the state this morning.

A low pressure trough is moving across the northeastern part of the state with very moist and unstable air mass ahead. That might lead to the development of severe thunderstorms in the north east of NSW today.

Severe thunderstorms are likely to produce large hailstones and heavy rainfall that may lead to flash flooding in the warning area over the next several hours. Locations which may be affected include Armidale, Tamworth, Gunnedah, Walcha, Quirindi and Uralla.

The State Emergency Service advises that people should:
* Park your car under secure cover and away from trees, powerlines and drains.
* Secure or put away loose items around your house, yard and balcony.
* 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.
* Stay indoors away from windows, and keep children and pets indoors as well.
For emergency help in flood and storms, ring the SES on 132 500.
