Widespread rainfall and heavy falls are set to drench eastern and southeastern Australia over the coming days. A powerful low-pressure system over South Australia, fueled by tropical moisture and atmospheric troughs, is bringing extensive cloud cover and showers.
Transcript
00:00Widespread rainfall and areas of heavy falls are developing through eastern and
00:04southeastern Australia over the next few days. So let's have a look at our satellite imagery
00:09where we can see a low pressure system spinning over South Australia as well as plenty of moisture
00:14streaming down from the tropics. Now that is bringing an area of extensive
00:18cloud and showers through eastern Australia. Now those showers and thunderstorms have developed
00:24over the past 24 hours where we've seen falls up to 60 millimetres through New South Wales,
00:30up to 70 through Tasmania, around 20 millimetres through Victoria and 40 through southeast South
00:36Australia. Now with plenty more rainfall on the way we have issued a severe weather warning for
00:43eastern Tasmania for tomorrow Wednesday with heavy falls above 50 millimetres possible. Now we're also
00:50looking at the risk of severe thunderstorms developing through much of eastern Australia
00:55over the next few days. So let's have a look at those areas. Starting with today Tuesday where
01:01the area in yellow denotes the area of severe thunderstorms with heavy rainfall possible.
01:06So that's starting through the central west of New South Wales through the middle of today and then
01:11extending south towards the south coast of New South Wales and the far east of Gippsland in Victoria
01:17throughout this evening. Now if these heavy falls do eventuate we will be issuing severe thunderstorm
01:23warnings. Heading into tomorrow Wednesday where we can see that area in yellow shifts northward
01:29into southern Queensland and northern New South Wales. Now in addition to heavy falls tomorrow we could
01:36also see areas or storms with damaging winds and large hail through parts of southern Queensland.
01:43And on Thursday that area contracts to the east focusing on southeast Queensland and parts of central
01:50and northeastern New South Wales. So what systems are really driving this wet and stormy weather over
01:57the next few days? We have a low pressure system sitting over South Australia as well as plenty of moisture
02:04streaming in from the tropics and a number of trough systems. These are being enhanced by a trough through the
02:11upper levels of the atmosphere which is really bringing that enhanced rain activity. Now into
02:17Wednesday and Thursday this trough will continue through the northeast through to north southern
02:23Queensland and northern New South Wales those areas where we're likely to see some of those heavy falls.
02:28We also have this trough system developing through Tasmania bringing that moisture and easterly flow and
02:35that risk of heavy falls. Now into Friday we have this low pressure system moving offshore however plenty
02:42of moisture will still be wrapping around that system bringing that ongoing risk of heavy falls to
02:47coastal parts of New South Wales on Friday. So with a few days ahead of rainfall we are looking at
02:54accumulated totals of about 25 to 100 millimetres through southern Queensland with some of those heavier
03:01falls about the Darling Downs. 50 to 100 millimetres through the New South Wales western slopes. Falls of
03:07100 to 150 millimetres are possible about the New South Wales coast although it depends where that low
03:14does move and 50 to 100 millimetres through eastern Tasmania. Now of course with all this rainfall we are
03:21looking at some impacts over the next few days starting with both flash and riverine flooding. So we may issue
03:28some flood watches and warnings over the next few days then there's also that risk of flash flooding
03:33and dangerous driving and travel conditions so please stay safe on the roads and keep up to date
03:38with your local emergency services. It is also welcome rainfall for some agricultural areas which have
03:44seen a dry autumn including parts of inland south east Queensland and northern New South Wales.
03:51That's all for our update today as always please keep up to date with our forecasts and warnings at the
03:56Bureau's website app and social media.
