Hello from the Bureau, here with a Severe Weather Update on the ongoing multi-day heavy rainfall event that continues to impact central parts of the country. And then tomorrow, tropical moisture is expected to again extend down into the south-east, with heavy rainfall and severe thunderstorms likely across Victoria.

But first, let's just focus on today. We do have a Severe Weather Warning current that extends from the Northern Territory into the upper west of New South Wales, including the North-East Pastoral district of South Australia and parts of the Channel Country of Queensland. Now, within this warning area, heavy to locally intense rainfall is possible, as well as damaging wind gusts.

Now rainfall totals within 24 hours are expected to be between 100 mm to 140 mm throughout that northern area, whereas throughout that southern flank, 50 mm to 90 mm is likely within a 24-hour period.

Now taking a look at the water vapour imagery, this really highlights well where moisture is sitting across the country. And we have this low sitting over the Northern Territory that's drawing a huge amount of tropical moisture into northern and central parts. Also noticing the cold front that brought the rainfall to the south-east has now moved out into the Tasman Sea and left a much drier air mass in its wake, shown here by those brown tones.

Now I'm going to show you the precipitable water values. These are showing how much water is available in the atmosphere to be rained out, and it's really showing as we move into tomorrow, into Tuesday, heading into the afternoon and early evening, that really high values up to 50 mm extend down into southern parts of Victoria. What this means is that the tropical moisture is extending along that trough line, but it's also highlighting the potential for heavy rainfall and an increased risk of flash flooding.

Now, because of this, we have issued a Severe Weather Warning for heavy rainfall across northern and southern parts of Victoria. Now this includes places like Echuca, Bendigo, Seymour, Mount Buller, Warragul and even the Melbourne metropolitan area. Now the heavy rainfall is possible about western suburbs of Melbourne during the morning and then extending into the eastern suburbs in the remaining warning area during the afternoon and evening.

Now within this area, six-hourly rainfall totals are possible of 40 mm to 70 mm, that may result in flash flooding. For this reason, we are expecting to issue a Flood Watch across large catchments across central and eastern parts of the state, including across the Melbourne metropolitan catchments.

Now, as well as the heavy rainfall, severe thunderstorms are likely across a broad area of eastern and central parts of Victoria to bring heavy rainfall, but are also possible anywhere within these yellow areas, including for western parts of Victoria and for New South Wales. And then also noticing those severe thunderstorms likely in the vicinity of that low pressure system, bringing heavy rainfall.

Now, with all of this heavy rainfall, Flood Watches have been issued, extending all the way from the tropical north down into South Australia, but as well through north-western parts of New South Wales. And there are already a number of Flood Warnings across Queensland due to recent rainfall, as well as the Major Flood Warning for the Flinders and the Cape rivers. So that's really indicating the grounds are already really wet and catchments swollen, and will respond very quickly to any further rainfall.

Now some weather watch points with this unfolding weather situation include, of course, the possible flash and riverine flooding with the heavy rainfall, but as well the potential for hazardous driving conditions with the potential for disruption to travel, but as well potentially roads to be cut off and communities isolated. Agricultural impacts throughout central Australia include a threat to livestock and cattle, whereas agricultural impacts throughout the south-east are much more of a positive, good news story, with a number of areas quite desperate for some good rainfall following a dry summer.

Now, taking a look at the rainfall as it moves through to tomorrow, that rain band is expected to develop during the morning and then slowly move eastwards with that trough. And as we head into Wednesday, heavy rainfall with storms continues through eastern parts of Victoria and potentially south-eastern parts of New South Wales as well.

Also just noticing that low pressure system lingering through central parts. In fact, it's not meant to move until potentially Friday later this week, with heavy rainfall possible each day this week.

With so much going on around the central and south-eastern parts of the country, now is a good time to stay up to date with our forecasts and warnings via the Bureau website, app and social media. And as always, listen to the advice from your local emergency services. Bye for now.
