00:00A weather event is brewing which will bring multiple weather hazards over multiple days
00:05to large parts of southeastern Australia from as early as this afternoon.
00:10I'm Angus here at the Bureau, it is Thursday and this is a severe weather update and let's
00:14start with our observations on the rain radar. What's been going on with the rain this morning?
00:19Well for southeastern Australia we can see this big band of wet weather sweeping
00:23across New South Wales and ACT associated with a cold front moving through the area.
00:28There's some further showers in behind as well affecting Tasmania and Victoria and some very cold air
00:34moving up from the south but I really want you to focus in on this area here where we're seeing
00:39some stronger radar echoes there in the yellows and the oranges showing us heavier rainfall and the
00:45development of thunderstorms and it is those storms which could go on to affect a number of areas over
00:51the next few hours. Here is our severe thunderstorm outlook for Thursday afternoon and really I want
00:56to draw your attention to the yellow and the red areas on the map which is where severe thunderstorms
01:01are possible including right through this area in southern and eastern New South Wales.
01:06These severe storms could cause areas of heavy rain and flash flooding, damaging winds and even
01:11large hailstones over the next few hours. This looks most likely in this red region here which
01:17includes parts of Sydney, the Illawarra and Wollongong and that could occur right on the evening rush hour
01:22between 4 and 7 pm on Thursday. This may cause delays and disruptions out and about as you go
01:29through your way this evening. More broadly speaking severe storms are also possible up through parts
01:33of the Hunter into the Tablelands and even out to the northwest slopes and plains throughout the second
01:38half of the day today. Our focus for this afternoon will be on those severe storms but the weather event
01:43which is driving those severe storms is going to continue into Friday and even though that initial band of wet
01:50weather
01:50which we're seeing on the radar at the moment will move offshore we're not done with what's going on
01:55because as that pulls away along that frontal line this low pressure area will develop and through Friday
02:01this low pressure area will deepen as it just hovers off the east coast of southern New South Wales.
02:07In particular take a look at this belt of strong winds which is going to wrap around the low pressure
02:12area
02:13coming up from the south. That will bring some really gusty conditions to parts of eastern Tasmania,
02:19eastern Victoria and into eastern and southern New South Wales and ACT and because of that we've gone
02:24ahead and issued some severe weather warnings for the southeast of the country. These are our warning
02:29areas focused on Victoria and New South Wales but we actually see some slightly differing details on either
02:35side of the state boundary. So we'll start off in Victoria where we've got the warning in place for damaging
02:40winds
02:41through eastern parts as well as the central ranges north of Melbourne. Wind gusts up to 100 kilometres
02:46an hour are expected from Friday morning through until Friday evening but we also could see some
02:51heavy rainfall through East Gippsland and that's included in the warning as well. Six hour rainfall
02:56totals of 60 to 80 millimetres through eastern Victoria could lead to areas of flash flooding or may cause
03:01the rivers to rise through East Gippsland. For the New South Wales side of the border broadly speaking we're
03:07just looking at damaging winds being our warning criteria. 100 to 110 kilometres an hour possible
03:13through a large area that's really really strong wind enough to bring down some trees and cause some
03:18damage to property. The strongest gusts up towards that 110 kilometre mark expected to be in the Illawarra
03:24and the south coast from Wollongong down to Eden. Let's move on because Friday into Saturday this low
03:31pressure area only very very slowly moves away from the country so we'll continue to see these very
03:37strong winds affecting eastern parts and gradually they will peel away from mainland Australia but
03:43importantly the strong winds will continue over the ocean and that will drive continued hazardous surf
03:50and large waves. So I've got the swell map here showing us the forecast swell height for southern
03:56and eastern Australia and that is really going to crank up on Friday as this low pressure area starts
04:02to intensify. So big big waves from eastern Tasmania up towards Sydney. We could see some waves in the
04:08six to eight metre range for deeper waters offshore maybe four to five metres for closer into the coastline
04:15here. That is large and powerful waves because of that we've issued this coastal hazard warning for
04:20eastern New South Wales. I'll just put the details on here. The warning is in place from the state border
04:25with
04:25Victoria through Marimbula all the way up to Seal Rocks which is between Newcastle and Foster. That
04:31does include the coastline of the Illawarra, the Sydney area and the Hunter and in that region we could
04:36see coastal erosion where powerful waves batter exposed southern facing coastlines eating away at beaches
04:43and causing damage and erosion along the shore. We could see some really large waves both inshore and over
04:49deeper waters as well making activities on and near the water pretty treacherous. The final
04:55thing I want to mention before I wrap up this video is the temperature because as this cold front moves
05:00through it is going to lead some very cold conditions over the southeast. Here we're looking
05:05at temperatures across the country just a little bit above the surface to give us an idea of what's
05:09going on and the blues into the greys into the pinks are where we expect to see the coldest temperatures.
05:15This big bubble of cold air is going to move northwards in the next few days and look how we
05:20see cold
05:20conditions through New South Wales, Victoria, ACT, Tasmania, South Australia even into southern
05:26Queensland. Here's a look at Friday's maximum temperatures. This is going to be a stark reminder
05:30that winter is ahead of us and summer is behind us. These temperatures are looking pretty chilly
05:36including maximums of 15 for Hobart, 15 for Canberra and 16 for Melbourne. The coldest temps of the year so
05:41far and some places will be pushing records for the coldest temperatures ever recorded in the month of
05:47March. So be it cold temperatures, damaging winds, large waves or severe thunderstorms, many people
05:53will be impacted by this weather event between today and Saturday. So make sure to stay up with
05:57the latest including all those weather warnings on the Bureau's website and the BOM Weather app.
06:02Thanks so much for watching.
