‘Deep low’ could bring chaos to WA

A WEATHER system so fierce it only hits Australia twice a year has led to warnings of heavy rain, thunderstorms and 125km/h winds.

The Bureau of Meteorology is warning residents of Perth, Bunbury and Albany, as well as much of the rest of southwest Western Australia, to buckle up and stay safe on Wednesday as a "deep low" rolls through from the Indian Ocean.

"The passage of a strong cold front and deep low will result in the potential for severe weather conditions," the bureau said early on Wednesday morning.

The battering could last for as long as 24 hours, may produce hail in places, and will be stronger and wider than a typical front.

Perth can expect to see around 20mm of rain on Wednesday with showers every day this week.

Sky News Weather forecaster Samantha Chiari said it was "all about to unfold" in the west.

"Batten down the hatches if you're in southwest Western Australia with another vigorous cold front driving showers, thunderstorms, damaging winds and dangerous surf," she said.

Tides are likely to rise above the normal high tide mark on Wednesday morning with very rough seas and potential flooding of low-lying coastal areas.

Gale force winds of up to 100km/h could result in damage to homes and property while individual gusts may exceed 125km/h.

The first winds are likely around 10am local time on the southwest coast, extending into Perth from around noon.

"This sort of system only hits the southwest corner of WA twice a year, just to give an indication of how powerful it is," Ms Chiari said.

"It will affect Perth, Bunbury and Albany so it's not an ideal hump day. Stay indoors if you can," she said.

The cold front is then expected to sweep across the Great Australian Bight towards the eastern states over the next few days bringing rain. But its wilder streak will have calmed down before it reaches Adelaide and Melbourne.

Conditions in South Australia, Victoria and Tasmania are now easing back after a cold front barrelled through earlier in the week bringing stormy conditions. It will be partly cloudy in those states on Wednesday and Thursday with a possible shower. Temperatures will be around 12-14C in Hobart, 15C in Melbourne and potentially as high as 19C in Adelaide on Thursday.

NSW and Queensland, in contrast, are far sunnier with a high of 22C in Sydney on Wednesday and 25C in Brisbane.

There could be some rain in southeastern parts of NSW spreading into Sydney later in the week.
