A COLD front brought isolated thunderstorms and widespread rainfall over south-west Western Australia.

Bunbury had its highest daily May rainfall on record at 73mm in the 24 hours to 9am on May 29.

This cold front interacted with tropical moisture and moved across WA into the Northern Territory and South Australia, generating broad areas of rainfall from the north-west towards south-eastern Australia.

Daily rainfall totals of 25-50mm were recorded in areas around Alice Springs on May 30.

The rain band continued through south-eastern Australia, bringing damaging wind gusts over elevated areas and widespread rainfall, with localised overnight heavy totals in north-eastern Victoria.

Many sites recorded their highest daily rainfall for May, including Mount Hotham, which recorded 116mm of rainfall, and Falls Creek, which recorded 85mm.

An offshore low brought significant rainfall to NSW from May 31 to June 2, which exceeded some June daily rainfall records in the Sydney area.

The highest weekly total was 158mm at Rose Bay, Royal Sydney Golf Club (NSW), which also recorded the highest daily total of 157mm in the 24 hours to 9am June 2.
