00:00 Hello, I'm Angus Hynes here at the Bureau of Meteorology.
00:03 This is a severe weather update to keep you on top of what's going on with the heavy rain
00:07 in the southeast.
00:08 It's been a couple of very wet days with more rain to come across southern New South Wales
00:12 and eastern Victoria.
00:13 Let's dive in and see.
00:15 This is the pressure map for the whole of the country but our focus is really on this
00:18 part here.
00:19 So in fact let's zoom in and get a bit of a closer look.
00:22 And it's a low pressure centre, particularly this low pressure centre here which is steering
00:26 the wind and the rain dragging this moisture down from the humid tropics and just ramming
00:31 it into southeastern parts of the country.
00:33 And that's why we've had so much heavy rainfall.
00:35 And as we play through this for the rest of Thursday and into Friday we'll see it takes
00:39 a long time for this low to vacate the premises.
00:41 It just keeps steering the rainfall into the southeast so it's a very wet day through Thursday.
00:46 Eventually on Friday we'll start to see this low move further and further away from the
00:50 coastline but it takes a while for that rain to clear up.
00:54 It's not a complete drying trend.
00:55 What we will see on Friday is the rain thins out and becomes more sparse and loses some
01:00 of its intensity.
01:02 But we will still see patchy wet weather falling onto these waterlogged, saturated parts of
01:07 the country through until at least the weekend.
01:09 And that is why we have maintained some areas of severe weather warning.
01:12 These yellow regions are weather warnings for both incoming heavy rain as well as damaging
01:17 winds.
01:18 Primary concern through these areas here is likely to be a continuation of the flooding
01:22 which we've already seen impact large parts of eastern Victoria and southeastern New South
01:26 Wales.
01:27 The combination of wind and rain can also bring down trees which can damage property
01:32 as well as potentially fall onto power lines and cause power outages.
01:36 Don't forget, with the heavy rain on top of the wet weather we've had over the past few
01:40 days, slips and landslides certainly not out of the question either.
01:44 Let's see how much rain we are forecasting for the next few days.
01:47 This is Thursday and Friday's rain all kind of meshed together on one map, totalling about
01:52 100mm in this part of the country, right along the border region here, that's the purple
01:56 contouring 100mm plus.
01:58 That's falling on top of the rain we've already seen which is suggesting some parts of eastern
02:03 Victoria and Gippsland might get 200mm total through the course of this event and maybe
02:08 touching on 300mm for areas of southeastern New South Wales.
02:12 That is enough to cause a lot of flooding, that rain has got to go somewhere, it goes
02:16 down through the rivers so no surprise to see we have got some flood warnings in place
02:20 for these southeastern rivers.
02:22 We've got the Genoa and the Canne River both at moderate flood warning down the border
02:26 region here and the Thompson River here in Gippsland as well as a whole network of minor
02:31 flood warnings through these southeastern rivers and it's possible we will add more
02:36 warnings to this map here because even once the rain has gone, the flooding can stick
02:41 around, it takes a while, a few days sometimes for that rainwater to drain out through the
02:45 rivers so do keep an eye on the flood warnings around your part of the country.
02:50 If you'd like to see the latest severe weather warnings or your local forecast, we've always
02:53 got up to date information at bom.gov.au and set your location at the BOM Weather app,
02:59 you can get alerts if there are warnings for your region.
03:01 That's it for now, we'll see you next time.
