00:00 High temperatures and fire dangers are on the way for southeast Australia over
00:04 the coming days, particularly impacting Victoria, Tasmania and South Australia,
00:08 which are all in for a public holiday long weekend. Let's set the scene by
00:13 jumping straight into our latest heatwave maps. Now for the Thursday to
00:18 Saturday period we can already see wide areas of low-intensity heatwave. As we go
00:23 through the Friday to Sunday period we start to see the severe intensity
00:27 heatwave developing through southern parts of the mainland, really peaking
00:32 through the Saturday to Monday period. It's at that time that we're seeing the
00:36 greatest area covered by the severe heatwave conditions, not just southern
00:41 South Australia and Victoria but parts of northern Tasmania as well, and that
00:45 hits many of our major town centres including Adelaide and Melbourne. Now
00:49 just as a reminder for everyone, a severe heatwave or any heatwave is not just
00:54 one hot day and night, it's a three-day period of unusually warm daytime and
00:59 nighttime conditions that is really hard for the body to recover from. It's a sign
01:03 to us that we need to stay cool, stay hydrated and if you or someone you know
01:08 is particularly sensitive to heat, check in with your local health services to
01:12 see what extra precautions you can take across this weekend. So what temperatures
01:18 do these severe heatwaves equate to? Well looking at Friday's maximum
01:22 temperatures we can see warm to hot conditions have already developed across
01:26 much of the southeast, but the temperatures will really peak on
01:30 Saturday. We've got widespread temperatures in the mid to high 30s
01:34 pushing into the low 40s inland, Adelaide getting up to 40 degrees, Melbourne 39
01:38 and Hobart 33. Coinciding with those highest temperatures we're also seeing a
01:44 peak in the fire danger ratings. For tomorrow it's all moderates to high but
01:49 going into Saturday we're seeing some extremes starting to come through for
01:53 some districts of southeast South Australia and it is possible over the
01:57 next 24 to 48 hours that we'll see further fire weather districts upgraded
02:01 to extreme fire dangers as our assessment of the situation continues.
02:05 Now usually with a day of peak heating and peak fire dangers we have that
02:10 followed by a cold front moving through and easing conditions, but unfortunately
02:14 that's not quite the case with this long weekend. If we look at Sunday's fire
02:19 danger ratings we can see that elevated fire dangers, high fire dangers persist
02:23 through Sunday through that later part of the weekend and our temperatures
02:27 remain high as well. Sunday's maximum temperatures are still in the mid to
02:31 high 30s if not low 40s for much of the southeast with very little change
02:36 following through on the Monday as well. In fact it's not until the Tuesday that
02:40 we start to see some milder air extending through Tasmania and southern
02:44 Victoria bringing relief to some people at last. Now the reason for this is that
02:49 we do have a cold front moving through but it's fairly weak. We can see it
02:53 moving across the Bight on Saturday towards Tasmania slipping quickly to the
02:57 south. Now it will increase the winds a little bit through Tasmania and parts of
03:01 Victoria on Saturday but because it's moving so quickly and moving to the
03:05 south it will have a weaker impact across those land areas. This trough
03:11 flying back across the mainland is going to bring some wind change to some parts
03:15 of southern Victoria and South Australia but it's not a decisive cold front with
03:20 a significant temperature drop. That won't come along until later next week.
03:25 So with a very hot long weekend on the way it is essential to keep up to date
03:30 with all of the latest forecasts and warnings via the Bureau's website and
03:34 the BOM social media. Have a good weekend and we'll see you next time.
