00:00A cold snap is sweeping across southeast Australia, with damaging winds, rain leading to flooding,
00:05and snow possible as far north as the Queensland-NSW border.
00:09The Bureau has issued severe weather warnings for damaging winds, and as of Monday afternoon,
00:14these cover coastal and elevated parts of Tasmania, Victoria, NSW and the ACT.
00:20In Tasmania, we've already seen wind gusts of above 100 kmh at Kennauk-Cape Grim, and
00:26for the rest of Monday, we could continue to see wind gusts of up to 100 kmh for parts
00:30of the Tassie West Coast, easing later on Monday evening.
00:34In Victoria, winds will increase during Monday, and may exceed 90 kmh for parts of the southern
00:40and southwest facing coast, as well as about Mount Baw Baw as well, and winds will ease
00:45later on Monday night and into Tuesday morning.
00:48Across NSW and the ACT, we start to see wind gusts of between 70-90 kmh develop across
00:54southern parts of the warning area, and these will extend north into the Central Tablelands
00:59and parts of the Illawarra, including Wollongong, into early Tuesday morning.
01:04And we could also see wind gusts in excess of 110 kmh about parts of the highest alpine
01:09peaks, and these winds will ease from later on Tuesday morning.
01:14With the forecast winds and snow, we are forecasting blizzard conditions for elevated alpine areas,
01:20which can make travel get dangerous.
01:22So if you are in these areas over the next day, be sure to follow all advice from local
01:26authorities, particularly as it is still the school holidays in NSW.
01:31The Bureau has also issued flood watches and warnings for Victoria and Tasmania.
01:36In Tasmania, minor flood warnings are current for the Hewan and St Paul rivers, where between
01:4240-70 mm of rain has fallen over the past 24 hours.
01:46With more rainfall expected, a flood watch is current for much of eastern, southern and
01:50central Tasmania, with the possibility of minor to moderate flooding.
01:55In Victoria, flood watches are also current, and these include for the Thomson, La Trobe
02:00and Goulburn rivers, as well as upper reaches of the Yarra River.
02:04With rainfall over the next 24-36 hours, minor to possibly isolated moderate flooding is
02:11possible, especially as these areas remain relatively wet.
02:15And so just how much rainfall are we expecting?
02:18We've already seen rainfall totals across parts of southern Tasmania, but heading into
02:22Monday evening, as this low pressure system moves towards Victoria, rainfall totals will
02:26build across southern parts of the state.
02:29Particularly for southern facing terrain, and that's where rainfall could be enhanced,
02:34and particularly in those southeast to southerly winds, that will pick up a little bit of extra
02:38moisture off the east coast of Tasmania, where sea surface temperatures remain relatively
02:42warmer.
02:43Heading into Tuesday, that's when we start to see rainfall totals build across southeast
02:47parts of New South Wales, and over the next 24 hours, we are expecting to see between
02:5215-50mm of rainfall, with isolated force in excess of 50mm, which may produce flooding.
02:59For the rest of Tuesday, showers will extend up into northern New South Wales, and it may
03:04be cold enough to see snow flurries for the northern Tablelands, and even as far north
03:08as the Queensland Granite Belt.
03:10But the further north you do go, those snow flurries are less likely to settle to the
03:14ground.
03:15So with damaging winds, the possibility of flooding and blizzard conditions, be sure
03:19to check for the latest information and updates from the Bureau's website and social media,
03:24and please stay safe.
