  Speaker 1: John Perlman on 702. 3 to 6 p.m.
• 0:05
  Speaker 2: Well, we've been having a conversation over many, many weeks
• 0:09
  Speaker 2: now about the summer we need to brace ourselves for,
• 0:13
  Speaker 2: given what's going on with El Nino. Most immediately, we're
• 0:17
  Speaker 2: expecting a massive heat wave in Gateng. To get details
• 0:23
  Speaker 2: of when and for how long and how intense this
• 0:27
  Speaker 2: is likely to be, we say welcome to Lihlohonolo Tobele,
• 0:31
  Speaker 2: who's a forecaster at the SA Weather Services. Very good
• 0:34
  Speaker 2: afternoon to you and thanks so much for giving us
• 0:36
  Speaker 2: your time. When does the heat start rising? How high
• 0:40
  Speaker 2: will it go and how long? Good afternoon to you.
• 0:43
  Speaker 1: Good afternoon and thanks for the invite.
• 0:45
  Speaker 3: So yes, we are expecting some heat, especially for the
• 0:49
  Speaker 3: central and the eastern parts of the country.
• 0:51
  Speaker 1: This will cover the Free State all the way.
• 0:53
  Speaker 3: Into the northwest, Gauteng, as well as parts of the
• 0:56
  Speaker 3: northern areas of the Northern Cape. Temperatures are expected to
• 0:59
  Speaker 3: range between 34 to about 40 degrees Celsius. It differs
• 1:03
  Speaker 3: from area to area, but the heatwave is expected to
• 1:07
  Speaker 3: last up until at least on Friday. We are currently
• 1:10
  Speaker 3: in that heatwave as you speak.
• 1:12
  Speaker 2: So peak temperatures, let's focus on Gauteng for a moment.
• 1:18
  Speaker 2: I don't know if it's going to be hot in
• 1:20
  Speaker 2: the Northern Cape. One would expect it would be. But Gauteng,
• 1:23
  Speaker 2: what are we looking at?
• 1:25
  Speaker 3: I mean, currently the heat wave will cover the central
• 1:28
  Speaker 3: and the southern parts, which then would include city being
• 1:31
  Speaker 3: and all the areas obviously in the southern parts, which
• 1:34
  Speaker 3: would look at temperatures between 34 all the way to
• 1:38
  Speaker 3: about 36 degrees Celsius.
• 1:40
  Speaker 1: It will differ from day to day.
• 1:42
  Speaker 3: But into most parts of Friday, we might start seeing
• 1:45
  Speaker 3: hot temperatures into the northern parts, which may also get
• 1:49
  Speaker 3: to about 38. But currently we're still looking at about
• 1:52
  Speaker 3: 34 to 36 degrees Celsius.
• 1:55
  Speaker 2: When do we get our first rain?
• 1:59
  Speaker 1: First rain?
• 2:00
  Speaker 3: We're expecting thunderstorms from Friday into the weekend. So the
• 2:04
  Speaker 3: weekend seems to be stormy, which will bring much more
• 2:07
  Speaker 3: of the rain. But I know a lot of people
• 2:10
  Speaker 3: have been complaining about the rain they received in the
• 2:12
  Speaker 3: past days, where it was a bit cool. But we're
• 2:14
  Speaker 3: still here to get much more of the storms, which
• 2:17
  Speaker 3: will bring the rain into the weekend.
• 2:18
  Speaker 1: So it's close, close, close by.
• 2:22
  Speaker 2: Okay, so one reason for that could be that there's
• 2:24
  Speaker 2: a cricket match starting at the Wanderers over the weekend,
• 2:28
  Speaker 2: which is always a good indicator of rain coming. Will
• 2:32
  Speaker 2: the rain cool things down or just simply make it
• 2:34
  Speaker 2: more humid?
• 2:36
  Speaker 3: The thing about the rain, it will be generally just
• 2:39
  Speaker 3: thunderstorms more than rain that is continuous. So it's not
• 2:43
  Speaker 3: only just going to bring rain, but you might also
• 2:45
  Speaker 3: want to look out for hail.
• 2:47
  Speaker 1: So it may cool.
• 2:49
  Speaker 3: Some temperatures definitely in some areas, especially south.
• 2:52
  Speaker 1: Over most parts of where the heat wave was.
• 2:54
  Speaker 3: So definitely we are looking at rain that may bring
• 2:58
  Speaker 3: some cooling. But with that happening with severe thunderstorms, you
• 3:01
  Speaker 3: never really know what to look out for. Only for rain,
• 3:05
  Speaker 3: we definitely look for different things. It brings damaging winds.
• 3:08
  Speaker 3: It brings severe thunderstorms. hail over some areas and much
• 3:12
  Speaker 3: more of the excessive lightning. So it's not only rain
• 3:15
  Speaker 3: that we'll look for into the weekend, but also some
• 3:17
  Speaker 3: thunderstorms that bring in lightning as well as the possibilities
• 3:20
  Speaker 3: of hail. And into some extent, you might see some
• 3:24
  Speaker 3: tornadoes in some places.
• 3:25
  Speaker 1: It differs from how severe the thunderstorm is.
• 3:28
  Speaker 2: Thanks so much to Lichlohonolo Tobela, forecaster at the SA.
• 3:33
  Speaker 2: Weather services, it's going to get hot, hot, hot. Hot,
• 3:37
  Speaker 2: it would seem. 702 Drive, 29 minutes to 4.
