Just starting to get heavy here now, had 15mm so far

Newstalk ZB reporting the Waimak is close to breaching. Yikes.

Snowing steadily in Methven

Newstalk ZB reporting the Waimak is close to breaching. Yikes.

Highly doubt it given the river is flowing at ~2000m^3/s and dropping with the stopbanks being designed for ~4700m^3/s

That reporter does not help the situation by relying on "eye witnesses" to tell him the Waimak is breaching its banks whilst he reports from the comfort of his desk at Newstalk ZB. Bad reporting inaccurate and darn well scare mongering for facebook clicks. Unfortunately this reporting causes the public to blame the media for fake news.

Just been over the Waimak Bridge, it's as high as I've ever seen it.

Been raining continuously here in Geraldine since yesterday. 48.6mm since 10pm last night.
Pretty sure I heard a distant roll of thunder in the early hours.
Temperture cooling down to 1C with sleet falling with the rain from after 10am.
Intersting to see how much snow is up there when this clears?

[einzack]

Snowing in Hororata.
Not too heavy by the photo I've seen, but enough to begin to settle....

Reports of snow to 100m in inland Canterbury from a few on Facepalm. One stating it is a severe warm air advection event.

Just cracks 40mm in Rangiora since last evening.

Some decent cooling under the heavy precipitation
I see on MS it is currently 2.7C at Ashburton, would be unusually cold in June for the time of day.

[Orion]

A few flakes of Stuff starting to fall here just now.
Plus rain.

The sleet getting heavier as the temperature falls

If anyone had bothered to check Ecan they would find a statement the Banks are not under any threat. Reporters inciting possible panic like this should be called out.

Below is a plot of all of the annual maximum river flows for the Waimak at the Old Highway Bridge, for this current event the peak flow has been 1983m^3/s

Thought this deserved its own topic for future reference will move posts across

Per MetService, Ashburton reading at 1:46pm, actual temp. 2.5°C.

Feels Like -2°C

[Dean.]

Wet snow falling now

[Chris W]

That's quite astounding for 1957, 3900 cumecs is a phenomenal flow rate!

The deep reds on the Canterbury radar seem quite well set at the moment.

I see Fairlie PWS on 1C with precip.

Snowing on the traffic cam. (Source)

I can remember seeing photos of the Fairlie Flyer train shunting along the main street of Fairlie in November 1967 with snow on the ground then.

Yes would have been a sign to see, what month was that i wonder and what would have been the rainfall readings on the West Coast.

[Richard]

Some rainfall amounts around this area are, here- 40.4mm Waiau 25mm and Cheviot 20mm. The 40 mm here is going to do wonders as its come straight after much of the silage and hay has been processed, those without irrigation should now get a good second cut.
