The rain gauge at Roebourne in the Pilbara filled up fast last night as Tropical Cyclone Veronica stormed down the Pilbara coast.
Between 8.30pm Monday and 5am Tuesday, more than 300mm fell — that’s the area’s annual rainfall in less than one day.
But the big wet is not confined to the east coast with forecasters warning the remnants of Cyclone Trevor could dump up to 150mm of rain in parts of eastern Australia over the coming days.
Our friends @dfes_wa have captured these amazing images from #CycloneVeronica. When you see this volume of water on the ground it’s apparent why we’re urging people to be careful even though conditions are improving. Multiple #flood warnings now in place https://t.co/4JHKIWGer9 pic.twitter.com/wGxHBKoeu6— Bureau of Meteorology, Western Australia (@BOM_WA)

Over in the west, Veronica is weakening. On Tuesday morning it was a category 1 storm but it looks set to lose cyclone status today as it continues its march south west.
Destructive winds and lashing rains are still a possibility but flooding is now the real fear as the moisture in the system finds its way to land.
Roebourne Airport’s 332mm in nine hours was more than a year’s worth. But Karratha, up the coast, saw just 13mm — proving how erratic in their path cyclones can be.
Veronica is expected to stay close to the coast, passing over Barrow Island on Tuesday, but wind shear is destroying the system reducing its intensity.
TREVOR BRINGS TORRENTIAL RAIN
It’s only the second time two cyclones have descended on Australia together. Trevor may have reduced in ferocity from a cyclone some days ago, but it’s still making list presence felt.
Almost the entirety of Queensland — from the coast to the outback — is likely to experience huge downpours while the eastern half of New South Wales and areas of the Northern Territory could see heavy rain as well, said Sky News Weather channel meteorologist Rob Sharpe on Monday.
Much of the coast could register at least 20mm of moisture by the end of the week. But Brisbane could get three times that and 100mm plus can be expected in some populated areas.
For Queensland and NSW it looks set to get soggier as the week progresses.
The downpours have begun already in Birdsville, in Queensland’s far west, where 21mm fell overnight on Sunday, its heaviest rain for 16 years. Menindee, in south west NSW, saw 15mm in the 24 hours to 9am Monday, its best rainfall in five months. In Tennant Creek, NT roads have flooded as over 100mm of rain fell between Sunday and Monday, the Bureau of Meteorology said.
A flood watch is in place in Queensland for the western Gulf Country, Channel Country, Central West and extending into the Warrego and Maranoa catchments
By Wednesday the moisture will be making a serious impact in populated areas.
“We’ve got still the remnants of Tropical Cyclone Trevor moving through Queensland and that’s set to see 90 per cent of the state seeing more than 20mm of rain.
“That’s a very substantial amount of rain,” warned Mr Sharpe who said flooding in the state’s west was a real possibility.
“That moisture on about Wednesday will start linking up with a low pressure trough over northern NSW. Into Friday and Saturday that’s when we’ll really see some decent rain throughout NSW while Queensland will continue to see some decent falls and thunderstorms,” Mr Sharpe said.
A possible later shower in Brisbane on Tuesday and then the rain settling in on Wednesday with a possible storm on Friday. Expect between 30 — 60mm of rain between midweek and the weekend.
Regional areas inland are set to be even wetter with Bedourie getting potentially near 100mm.
In NSW, Grafton, Ballina and the entire Northern Rivers could see up to 100mm with the rain focused on Wednesday and Thursday. Further south, the rainfall totals will be slightly lower but the upper level prediction for Port Macquarie is still around 60mm for the week.
Sydney will have a pleasantly warm week in the mid-20s with heavier showers a possibility on Thursday and Friday.
Canberra should remain in the mid-20s with few if any showers.
Dry in Melbourne but cool with most days struggling to get into the 20s. The warmest day should be Thursday topping out at 26C.
Across the Bass Strait there will be some showers here and there. In Hobart highs in the mid teens rising to the low-20s on Thursday.
Sunny in Adelaide with the mercury in the low to mid-20s for most of the week.
In Western Australia, expect a gloriously sunny week in the early-30s for Perth. But head north and Cyclone Veronica is still making its presence felt.
Over the border in the Northern Territory and it’s going to be wet in Darwin with the gauge registering between 20 and 100mm of rain this week as the effects of Cyclone Trevor continue to be felt.
A severe weather warning is current for damaging and possibly destructive winds along with the heavy rainfall in southeastern areas of the NT.
A flood watch is current for the Carpentaria Coastal Rivers, Georgina River, Simpson Desert and the Barkly as the system will lead to significant stream rises and localised flooding — many roads in the area are currently impassable due to the rainfall.
