Bucketing down in Chch this evening.

Never seen as much blue on the rain radar since May 2022.
Expecting a rather wet day tomorrow here and Monday. I like to see how the renewed soak pit will work.

[darcyplumb]

Temp has warmed up here significantly since 10pm last night. We haven’t had rain like this in a couple of years so I think there will be some issues at daybreak later on this morning. It seems the usual spots in Chch are causing problems.

I've never seen anything like this here before. Temperature has gone from 4c up to almost 10c since last night all without any let up of the rain. Metservice still showing 0c at Lake Tekapo so nearly 10c difference in temperature over just 600m of elevation difference.

Seen posting of flooding on State Highway One north of Ashburton - water across the road in a few places. Sandbagging was happening in Leeston during the night outside Crate and Barrel.
Looking on our cameras at work - so far the drainage outside our business is still working - fingers crossed it stays that way. Waiting for daybreak to check the rain gauge here in Rakaia.

Lots of flooding on the Methven Highway between Ash and Methven too. I’m about to go to work at New World… today is going to be mad I think.

Mt Cook Village is cut off due to continuing heavy snow.

[Dean.]

Over 70mm so far and still its belting down.
Heavy snow at Tekapo and the Asjburton lLakes 700 metres and still falling.
Edit 90mm here in town

[Cantab03]

93mm here so far locally in CHCH. Rain eased for now. Don't see much more than another 10mm today with BP doing more if a sheltering effect today with the more easterly airflow. Inland Mid Canterbury to get smashed today.

[Richard]

Been just a moderate steady rain here, 34mm so far

[Aucklandstorm]

Yeah I don't think I'm going anywhere, looks like we all stuck here, snowing for over 12 hours now.
Heavy now!

Must still be a bit of cold air stuck in the valleys and basins, Castle Hill also at 700m looks snow free on the webcam. Ecan website showing heavy rain at their Turton saddle site which looks to be around 1100m ASL on the mountains behind the southside of the Rakaia River.

Mild 10c here in South canterbury with 60mm of rain so far

[Aucklandstorm]

Turning to rain now.... might be good to go soon they are clearing up the roads quick

[Tracy Herbert]

82.5mm of rain in Rakaia for the event so far. Rain Gauge just emptied five minutes ago.

[Storm Struck]

Certainly the most significant prolonged heavy rain we've had here for some time overnight as expected.
A slight ease up this morning, although I see the rain bands are about to increase again soon as the surface models were predicting.
Unfortunately probably a further 60-70mm for Otautahi up until midnight tomorrow night, and more for Banks Peninsula plus inland areas.
The main issues will probably show up in a few days once the water tables rise along with the combined snow melt.

Perhaps a sunny window Tuesday before the polar surges start hitting us from Tuesday night.

Inland Mid Canterbury is in trouble today I think. I’ve seen some photos of significant flooding and a lot more rain to come.

I see NIWA's Akaroa site in BP recorded 199mm in the 24 hrs to 9am this morning - provisionally its wettest ever day from records since 1978.

[Simon Culling]

Nev, this tweet from NIWA quotes the Akaroa figure - but does not give a figure for Christchurch Airport. Is it much lower?

I can only think because Christchurch Airport is not part of NIWA’s network that they didn’t mention it because for the same period Christchurch Airport recorded around 85mm

[Orion]

My Methven Spy reports 110mm rain to this morning.

[darcyplumb]

My Methven Spy reports 110mm rain to this morning.

A further 22mm of rain here in Rakaia since my last report this morning. That’s 104.5mm of rain here so far for this event.
