Weather forecasts DO NOT promise anything and are more of a guide of what is expected to happen and looking at the forecast, it said 20 to 40. The issue is that many people look at the higher percentage other than the lower percentage.

Not all forecasts are going to be right. The Bureau UPDATE their forecast daily while some Social Media Platforms do not. They should ALWAYS look at the BoM's forecast and go from there, and use Social Media to get another Idea and maybe ask some questions. Meteorology is a hard science to master as you need to know a tonne of things that are happening in the atmosphere.

Factors on these types of systems are reliant of the steering winds of the streams to move showers to align in particular areas, but the angle was not favourable for parts of the Yorke Peninsula.

haha not needed explain, I know answer, friend no too. Unless you defend them maybe. No name need mention, but people found out correct way, ok now they not use and word spread good. Bureau not good either, only guide. Best way learn your own, like me and friend.

Tried put photo here Bonsia, not easy, read how later.

Good rain for hill and dam on radar now.

Yeah I'm still here, just forgot about the weatherzone forum due to lack of Real Rain systems this year.
19.5 mm system(s) total. So a bit wettish.
Drove through a heavy shower about 7 pm ish around Enfield on MAIN NORTH ROAD. Had wipers on flat chat, slowed down to 40 kmph, drove through a few massive puddles and rivers across the road, but made it through up over the bridge at DRY CREEK and it was dry past the Salisbury highway overpass bridge.

Yeah, there is no photo storage on this forum.
I upload photos to imgur and then link which is pretty easy.
You can of course use any photo sharing service that you prefer

46mm in my rain-gauge now out of this.

Looks like a stream drifting up north - seems Farrel Flat coming into it. Yorkes and the Hummocks area as well for a while.

yes betsuin, the uncommon wsw-sw (often with curved flow) stream off Spencer gulf can deliver some great falls up here as it lines up our topography at a right angle and last night was no exception. Our biggest fall by far this entire event...19.2mm overnight. Plenty of lashing rain and solid gusts. often have to wait until the highs get close after series of fronts to get the sou-westerlies we need. Still have some ssw showers and very cold air to come this evening.

Nice to finally score as we only got 4.5mm from the first couple of fronts, westerlies no good for here.

Now at 39.2mm total

Another 7.3mm brings the running total to 27.9mm.

A few brief showers today with some cold gusty winds associated with them. Was quite pleasant to be out in the garden when the sun was out.

That's a great site Betsuin.
Is it the same one as? https://www.waterconnect.sa.gov.au/Systems/RTWD/Pages/Default.aspx
Rain total even along the coast dependent on the shows within some narrow streams that generally are literally JUST North or JUST South of West Lakes Mall. When they do occur here though, help a lot to push up totals. Can anyone explain why these very narrow stream showers occur? TIA.
At any rate, stream showers overnight added to a rare for here, healthy, 29.5ml Winter rain event.

Saltspray - when it comes to streams and that small of a scale, it would depend on where precisely the convergence lies over the gulf, how much moisture is coming in from the ocean and the exact stream direction as landmass can shadow (e.g. ki). I assume also the wind stream direction and strength going up in height will also help to narrow or widen these areas of rainfall. (e.g. a slightly veering or backing shear profile might cause taller convection to change course slightly to the mean surface flow or spread the upper part of the cloud structure further east/west widening the stream in places). Generally though at night, very slight land breezes pushing over the warmer water help to establish thin lines of cloud along convergence boundaries producing narrow corridors of rainfall. A change of only a few degreees in windstream directions will be enough to move these lines slightly.


Still getting some very light showers but wont accumulate much more.

43.8mm total, a decent drop. Creeks are still mostly dry around here though after such a dry past year.
