Heavy rain and hail hits Wheatbelt

Hail and heavy rain bypassed Perth but dumped a bucket on parts of the Wheatbelt this morning, with one resident describing his backyard as a winter wonderland.

Goomalling resident Kristian Carr reported "golf ball-sized" hail that had transformed his backyard into a winter wonderland.

Julian McGill, who farms at Wyening, near Calingiri, recorded more than 20mm of rain in less than 20 minutes at 4am.

Trees on the family farm were stripped bare in the storm.

A suspected lightning strike caused a mass blackout across multiple suburbs and an estimated 27,000 homes.

The Bureau of Meteorology cancelled a severe thunderstorm warning for the Perth metropolitan area, but said large hail stones, heavy rainfall, flash flooding and damaging winds were felt to the east of the foothills.

A severe thunderstorm warning has now been issued for the Goldfields and parts of the Great Southern. Locations which may be affected include Merredin, Narrogin, Corrigin, Hyden, Lake Grace, Lake King, Pingelly, Wagin and York.
