A band of heavy rain is moving across the country from coast to coast, with intense falls to hit over the first week of May, 2024.

00:00Showers and rain areas to continue impacting not only parts of eastern but
00:04also northern New South Wales. Now looking at yesterday and overnight we
00:09saw widespread areas of rain around the central and Hunter Coast with
00:13widespread falls on the coast of the Hunter of around 50 to 70 millimetres
00:17and a few falls up to 90 millimetres. We also saw from heavy falls on coastal
00:22parts of Sydney around 40 millimetres at Bondi and 70
00:26millimetres around Monovale. We're also seeing some showers as well across
00:30northern areas. Now these coastal showers will continue in the coming days but
00:34our eyes are starting to move towards the latter part of the week and into the
00:37weekend. The reason for that is here on the water vapor imagery. This gives us an
00:42idea of what's going on in the upper levels of the atmosphere. Now what I want
00:45to draw your eyes to is this area of dark grey and orange over the South
00:49Australia area. That's a developing upper level low pressure system. Now as that
00:54continues to track towards the east over the coming days it's going to
00:57interact with some moisture coming in for the easterlies and develop rain
01:00through inland areas and then spread across to eastern parts of the state as
01:04we move into the latter part of the weekend. So let's look at that in more
01:08detail. Today the focus will just be some coastal showers along the New South
01:12Wales coast, just an isolated shower or storm through inland areas. Then as we
01:17move into tomorrow that upper low that I mentioned is going to interact with more
01:20moisture on tomorrow afternoon to bring showers and thunderstorms through parts
01:24of New South Wales and southern Queensland with that onshore flow
01:28continuing to bring showers across eastern New South Wales. Then we start to
01:33see things really ramp up on Friday as we see more moisture get fed into this
01:37upper low. It's going to bring a band of rain and thunderstorms through much of
01:40inland New South Wales and southern inland Queensland and some of those
01:44falls could be in that 15 to 25 millimetres and maybe in isolated falls
01:48even higher than that with coastal showers continuing particularly around
01:52the central coast. Then as we move into the weekend we'll see that upper low
01:56start moving to eastern parts of New South Wales and southeast Queensland
01:59bringing widespread rain and shower and thunderstorm activity to much of
02:04northern central New South Wales and even to southeast parts of Queensland
02:08as well on Saturday and then slowly moving offshore on Sunday but
02:12onshore flow continuing to bring rain and showers to the coast of New South
02:17Wales. So how does that look like from total rainfall over the coming days?
02:20Well over the next five days we're likely to see widespread 15 to 25
02:25millimetres and because the isolated falls up to 50 millimetres through some
02:28areas of northern New South Wales. Now this is just one solution and one where
02:34we could see those rainfall numbers in different parts of the state at
02:37different values. But note the main focus will definitely be along the coast of
02:41New South Wales particularly the Mid North Hunter and around the Sydney area
02:44where we could see five-day rainfall totals in that 50 to 100 millimetre
02:49range with isolated falls even higher than that. So if you're out and about
02:53this weekend or travelling around the state make sure you continue to stay
02:57updated with the latest forecasts and warnings as we approach the weekend and
03:01we'll continue to keep you updated here at the Bureau.
