Intro Heavy rain and
damaging winds to impact parts of Tasmania and possibly Victoria
on Sunday and Monday. And while Severe Weather Warnings
aren't current right now, we expect them to be issued
later on Saturday, especially around the eastern
and south-eastern parts of Tasmania, for damaging winds
and possibly heavy rainfall. And talking about rainfall, Flood Watchers we already have Flood Watches current
for large parts of Tasmania, including the populated areas
of south-eastern Tasmania. That means if you live in this highlighted
area, the forecast rainfall could lead to flash and riverine flooding,
and possibly into minor flooding as well. So, make sure you pay attention
to areas around here with that heavy rainfall on the way. But what's driving all of this weather? Low Pressure System Well, if we zoom out a little bit,
you can see a low pressure system developing off the coast
of New South Wales on Saturday, and it's going to rapidly intensify
as we move through the day on Saturday and Saturday night and it's going to take
an unusual direction. Generally, lows
here will go to the south-east, but this one is actually going
to go to the south-west and that means the weather
is going to shift into eastern parts of Tasmania
and southern parts of Victoria. So, as we get into the afternoon
on Sunday, notice the really strong winds and rainfall
wrapping around this low pressure system starting to impact eastern
and south-eastern parts of Tasmania and some of that energy and weather also getting up into parts of South
Australia and southern Victoria. Then as we move into the latter
part of Sunday, you'll see the low of getting pretty close
to Tasmania, with widespread heavy rain and gusty winds,
some possibly damaging. Now, I must stress
this is just one scenario. Some of our guidance has a low further north,
some further east, and some further south. So, that's why it's important
if you live in this area or know someone that does, to continue to
stay up to date with the latest forecasts and warnings across the weekend
in Tasmania and southern Victoria. Then as we move into later
Monday and Tuesday, continuing to see that heavy rain and strong
and possibly damaging winds impacting parts of Tasmania
and southern Victoria. Rainfall Now, when we start talking about rainfall,
pretty dry across Saturday but note the rainfall starting to pick up
as that rain shifts westward, which is highly dependent on the exact track and intensity of this low pressure system. But by the time
we get into Monday morning, we could see widespread falls of 50-80 mm
through southern and south-eastern parts of Tasmania, with isolated falls
even higher than that. And that's what could cause our flash
and riverine flooding issues. But not only are we going to have rainfall
and wind issues, Snow this cold air is going to spread across
much of south-eastern Australia. So, we could see widespread areas of snow. So, that's going to start in Tasmania
on Saturday shown here by these pink areas through here,
but also note some elevated areas of alpine areas of Victoria
and New South Wales snow starting to develop there
as we move through Sunday. But note as that air gets further north,
with some moisture, we could also start seeing snow
developing around the Central and even Northern Tablelands
of New South Wales on Monday and that will continue into Tuesday
and Wednesday as well. Finally, the other impact of this weather
system will also be huge seas and swell. So, this is a very large low
pressure system. and that's going to lead
to some very big seas and swell off the coast of New South
Wales, where we're likely to see Hazardous Surf Warnings there across the weekend
and into early next week. But also note towards parts of Tasmania
and even into western parts of Victoria, we could see very large seas and swells
there, with damaging and hazardous surf also possible as we move through Sunday
and particularly into Monday and Tuesday. So, with all this weather going on across
south-eastern parts of the country, particularly across
Tasmania and southern Victoria remember to stay up to date with the latest forecasts and warnings via
our website, app and social media. And when the weather does increase, listen
to all advice from emergency services.
