It seems Batman payed Wellington a visit tonight .

Only received 4.8mm from yesterdays system. Looking ahead though Monday's system should bring better rain hopefully.

Heavy shower passing over Lyttelton, looks to be brief though. Oddly WSW, we don't get many from that direction.

Yesterday's wet system moved away overnight with it becoming fine overnight with a minimum temperature of 4.5C.
Fine day but with increasing As layers and a NE wind developing, with it clearing for a time early this afternoon.
Today's maximum was 19.3C.
Cloud increasing from the west later this afternoon and evening with a light southerly blowing.
Snow on Mt. Peel from yesterday.

Yes, even though it was a surface southerly direction yesterday, the rain we got here was mainly moving from the WSW.
Depending on from the surface to upper air dynamics, I don"t know how it can influence the rainfall. I noticed that the Southerly buster, recorded at Ashburton airport, the sky looked dry behind it, but then the cloud did thicken up from the west and the rain developed, especially here in South Canterbury. There were one or 2 isolated heavy falls with the rain. Just like the downpour we got at 4:15pm on Wednesday.

Some insane flooding in the Plimmerton/ Kapiti Coast right now, looks like a massive rainfall and houses are flooded. Check out the dramatic video here:

MS going for 30mm in an afternoon for Chch, that volume that quick would cause issues round town, especially in the east

Gosh. There has been heaps of flooding around the north island this month. This time last year there was hints of a drought. Had been a wetter November here with some decent thunderstorms too

Not an interesting day weather wise here today.
Sunny this morning with the skies being what they call partly cloudy, however cloud increasing this afternoon with NE winds and thickening later this afternoon/evening. Today's maximum being 19.9C recorded around lunchtime.

A very high rainbow in the west at the moment.

A few spots of rain here, 10.0°C, calm.

MS has revised that down to 14mm for today now.

You've got to laugh, the Christchurch Gap is more than evident again...its uncanny how often this is happening this year. Now expecting 8mm if we are lucky, which is still good for the garden mind you

It should almost be called a thing.... The Christchurch Gap. Was thinking at least 10 to 15mm was a chance today, yet only 4mm so far with not a lot more it would seem.

11mm so far this afternoon in Rangiora, currently moderate rain for the last hour and very wet.
Actually been a wet month here with nearly 90mm.

Its personal Razor. Huey doesn't like you any more.

Soggy lunchtime run in Amberley, finally put the new rain jacket to use! Reasonable amount of standing water coming back into town though.

Huey must be liking me instead, had 15mm till 6.00 pm, weather station running an hour or so behind. Might end up around 20mm from this system.

Some surprisingly reasonable rain here this evening, 8mm for today
