Next Heavy Rain event 25-28 July
Here we go again folks. Buckle up.
From a Chch perspective I am nervous. Flood retention basins are chocker from last week. I'm not sure where 50-10mm possible falls might go.

Re: Next Heavy Rain event 25-28 July
Why does chch flood on such little rain? Was it like this before the quakes or have they changed the ground heights so much that it’s changed water flows?

Because of topography mate. Flat coastal former swamp, flanked by Port Hills

Another 12mm so far since late yesterday...

Re: Next Heavy Rain event 25-28 July
I'm a litte concerned as well, the ground can't take much at the moment and I'm sure we'll see some flooding issues around by the rivers again.

Re: Next Heavy Rain event 25-28 July
A very windy morning at my place so the likes of Tamaki Drive must be getting hammered. 12mm here since yesterday afternoon.
Milder air moving in today after a cold Sunday.

Re: Next Heavy Rain event 25-28 July
Latest trend in the models has this system lingering a bit further south than CHCH now, so CHCH may not get quite as much as initially was looking. Still be sodden though!

Re: Next Heavy Rain event 25-28 July
GFS kinda alone in suggesting that, looks like most of the other models are still going for 50mm plus

Central Otago may get off lightly if the Metservice is to be believed.

Re: Next Heavy Rain event 25-28 July
Even that last fall of 30mm the other day saw surface water flowing around here, the highest water table Ive ever seen.

22.5mm in my manual gauge for this event so far, certainly not as much as I thought we would be getting

Re: Next Heavy Rain event 25-28 July
No drizzle prior to it coming onto rain from 6pm.
Interesting to see how much will fall here from this event and to see how the local council got around to cleaning out the soak pits in our area.?

It’s the same down here in Mid Canterbury. The council have only today opened roads around Methven due to flooding. The Ashburton River would have to be of concern again.

Re: Next Heavy Rain event 25-28 July
Another saturated few days ahead for the region, as others have said waterways are already at full capacity so flooding will be an issue even by first light tomorrow.
Te Waihora Lake Ellesmere was opened up last week for one of its annual drainings, but has since reached capacity too so waterways backing around the area Coes Ford the Selwyn river etc will flood very easily.
Very showery off and on from Thursday to Saturday, and of note the last few days a very cold but short surge of air due through Sunday into Monday next week.

Re: Next Heavy Rain event 25-28 July
The heavier stuff seems to be setting in earlier than expected here. I see Porters Pass has snow falling. Going to be some big avo risks going forward on the fields

26mm for the event here. A strong wind at times.
I see Keikeri has nearly 200mm for the event, 540mm so far for July.

Re: Next Heavy Rain event 25-28 July
Some pretty serious surface flooding again on the way to work this morning. SH75 at the corner of lincoln/halswell rd is almost down to one lane. We look to be only 30-40% of the way through the rain so things will be a lot worse on the way home I'd imagine.
Metservice says 32mm so far today for chch city.

Much the same coming in from Rolly, all the catchments on the side of SH1/76 are well up and it's only just beginning.
This weather seems to bring out the worst in tailgaters and drivers as well.

Re: Next Heavy Rain event 25-28 July
Already had 40.6 mm of rain here since about 1pm yesterday.
Looking like it will continue with a similar amount today.
