For people in parts of Lower West and South West districts.

Issued at 8:42 pm Wednesday, 2 July 2025.

Severe thunderstorms with heavy rainfall and localised damaging winds about parts of the South West and Lower West districts.

Weather Situation: A slow-moving trough is in place over the far southwest of WA embedded in a moist and unstable airmass ahead of a cold front moving towards the coast. This is leading to the development of some slow moving thunderstorm clusters with a risk of heavy rainfall. Localised damaging winds will also be possible with isolated stronger storms near the coast north of Bunbury.

Severe thunderstorms are likely to produce heavy rainfall that may lead to flash flooding and damaging winds in the warning area over the next several hours. Locations which may be affected include Bunbury, Busselton, Mandurah, Collie, Dunsborough, Harvey, Bridgetown, Pinjarra and Rockingham.
