It looks like spring won't appear again until Tuesday with a severe weather warning issued for the South West with rain and plenty of thunderstorms closing in on Perth this weekend.

Foul weather has ruined weekend plans down south, with organisers of the Dardanup Bull and Barrell Festival cancelling the annual event due to wild weather and concerns for public safety.

"The stalls coordinator will be in contact with stall holders regarding refunds," the event's Facebook page said, with several photographs of the grounds showing heavy weather already setting in.

"Please know that this decision was not taken lightly and we would like to thank all our volunteers, sponsors and supporters. We will be back next year - bigger and better than ever."
