00:00 A very wet end to the week is on the way for much of NSW as a trough deepens along the

00:05 east coast.

00:06 Let's jump in with a look at today first of all.

00:09 We're likely to see fairly patchy showers along eastern parts of the NSW coast, with

00:15 fairly low rainfall totals expected.

00:18 A trough extending through northeast NSW and southern Queensland may generate some heavier

00:22 falls in these parts, particularly with thunderstorms this afternoon.

00:26 The story will start to change from tomorrow, however, with much wetter weather starting

00:31 to extend more broadly across northeastern NSW and down the east coast as well.

00:37 Now thunderstorms may bring heavy to locally intense rainfall to northeast NSW and southern

00:42 Queensland, but for the rest of the NSW coast, more moderate falls is all that's expected

00:47 unless we get those thunderstorms moving overhead.

00:50 As we go through the later part of Thursday and into Friday, though, that's when we'll

00:54 see the most severe weather starting to ramp up as a trough deepens off the east coast

01:00 of NSW.

01:01 Now, this trough is likely to drag in further moisture and direct it across eastern and

01:06 central NSW, with the risk of heavy falls becoming more widespread and intense.

01:12 We may also see strong winds wrapping around that trough and high seas and swells starting

01:17 to be generated offshore.

01:20 As we go through the day on Friday, we're going to start seeing a low pressure system

01:24 starting to develop somewhere on that trough, most likely pushing towards the southern coast.

01:29 The heaviest rain and the strongest winds are likely to be tied to wherever that low

01:34 may develop, but there's still an element of uncertainty as to exactly when and where

01:38 that will happen.

01:39 But as we go into the overnight period into Saturday morning, though, we're likely to

01:43 see it shifting south, taking the rain and the wind with it.

01:47 We may see some rain and wind impacts for East Gippsland through the day on Saturday,

01:52 but for the central coast and Sydney area, it'll be an easing weather pattern, with just

01:57 patchier showers likely to be lingering across those areas through Saturday afternoon and

02:02 evening.

02:03 Now, the rainfall totals over the Thursday to Saturday period are likely to reach 1–200mm

02:09 across southern Queensland and much of eastern NSW.

02:13 Isolated falls pushing above 200mm about some of those coastal areas and with any storms

02:18 that develop.

02:19 Now, rainfall of this magnitude can quickly lead to flash flooding, cutting off our roads,

02:25 making them impassable and blocking our drainage systems.

02:28 We may also see riverine flooding developing through Friday and into Saturday, with flood

02:32 warnings likely to be issued.

02:34 In fact, a number of warnings are likely over the coming days, including warnings for heavy

02:39 rain and flash flooding, damaging winds, particularly about the central coast, thunderstorms and

02:45 hazardous surf.

02:47 With a lot unfolding over the next few days, it is essential that you check the forecasts

02:52 and warnings regularly via the Bureau's website and the BOM Weather app, so that you and those

02:57 that you know in these areas can stay as up-to-date and as safe as possible.

03:01 We'll catch you in the next update.
