Two days of heavy rain have brought rain and storms to many states, with the SES warning of floods in the Macquarie and Hawkesbury districts of New South Wales.

Greystanes, in Sydney's west, received 23mm of rain in less than two hours.

Large swaths of Australia are expected to be soaked and chilled, with heavy rain and colder-than-average temperatures projected from the north to Tasmania.

Weatherzone projected that the city might set a new record for the wettest year ever this week, as per 9News.

With 2112mm recorded as of yesterday, 2022 is already Sydney's second-wettest year in 164 years of records. That is only 82mm shy of the 1950 record of 2194mm.

And, according to Weatherzone, Sydney had received just 1960.5mm of rain at this point in 1950.

With rain totals ranging from 70mm to 110mm anticipated between tonight and Monday morning, a new record is likely to be established in the coming days.

A dangerous surf warning is still in effect for much of the east coast, including Sydney.

Storms ripped across Adelaide overnight, bringing down trees all around the city.

Glass panes on a Rundle Mall shopping building were blasted out and crushed onto the road below.

The SES worked all night to clear up the mess, responding to 400 pleas for help.

The severe weather warning for the city has already been lifted, but more is expected, according to the Bureau of Meteorology.

Heavy rain is expected to fall across western and south-west Queensland, western and central NSW, and northern and north-eastern Victoria today.

Along the NSW South Coast, moderate falls are also likely.

Severe thunderstorms are expected on Wednesday, with heavy rain the major threat, particularly in southwest Queensland and western New South Wales.

Rainfall of 20-40mm is anticipated in southern Queensland, rural NSW, and northern Victoria today. Storm activity might increase rainfall of 40-60mm, with isolated totals over 100 mm likely.

The strongest rain will occur tomorrow in southeast New South Wales, the NSW South Coast, north-east Victoria, and high northern Tasmania.

Rain and thunderstorms, some severe, will swiftly develop over central NSW and Victoria as the cold front approaches, then move into eastern Victoria and NSW on Friday night.

"Many towns that have recently experienced or are now experiencing floods will likely see rivers increase in the next week," the Bureau stated in a release.

Rain will fall from the Top End to the eastern interior over the following five days, with peak rains expected on Wednesday and continuing in wide portions of NSW and southern Queensland until next weekend, as per The Guardian.

Showers may raise the risk of flooding in inland communities that have recently been inundated, including those where floodwaters have yet to recede.

Showers and thunderstorms will move from the Northern Territory to Adelaide and South Australia on Monday and Tuesday, with rain and thunderstorms also hitting western Queensland, western New South Wales, and north-west Victoria by Tuesday, according to Bureau of Meteorology meteorologist Jonathan How.

The worst rain is expected on Wednesday, with showers from north-east Queensland spreading west to rural NSW and northern Victoria, as well as strong easterly winds on the southern coast.

Showers, storms, and high winds will intensify in northern Tasmania on Wednesday evening and Thursday while lessening elsewhere.

A low-pressure system will drive additional showers ashore throughout the east coast by the weekend, bringing extra rain to parts of NSW and southern Queensland.

Rainfall of up to 50mm is expected across southern interior Queensland, parts of NSW, northern Victoria, and northern Tasmania on Friday.

Following significant rains last month, several localities in southern Queensland, inland NSW, and northern Victoria are still battling floods, and the BoM expects to issue further flood warnings this week.

Residents in flood-prone catchments should pay attention in the coming days, as already saturated catchments are likely to rise swiftly, according to How.

Temperatures will also be lower than normal for spring, as cloud cover and continuous rain combine to keep the temperature in the low 20s on the east coast and below 20C on the south.
