Rain getting heavier again in Rakaia as it eased off during the wee hours of this morning. Just the usual ponding of water out the front, certainly not to the extent of the surface flooding we had in July last year.
Rakaia, 118asl.

I've recorded 57mm so far. Bit chilly for the freedom campers on the Crown Range this morning...

Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
Classic....I wonder where they get their stats from for the most reliable model. I just ran the NOAA reports at 500 hPa anomaly correlation for the last 22 years and the last month over the southern hemisphere. Even the Americans report they are coming 3rd
1.EC
2.UK Met
3.GFS
4.CMC
5.France

Interesting also that the 59mm of rain reported by the CCC for this event in Chch up to 2am (see their press release this morning) was close the values the EC model has been spitting out for Chch for three or four days now (varied from about 53 to 62 from memory).

Re: Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
Chch was under a rain watch for 2 days while being modelled for 50mm of rain, then it changed late (yesterday morning) as these things do. Canterbury Weather Watch need to pull their heads in and let Metservice get on with their job during such an intense time as monitoring and forecasting on a storm. Calling and demanding a warning? Where is their accountability?

Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
Yes, and this has happened with every major rainfall event this summer. Its an interesting phenomenon, it seems to be a zone which extends from the coast through Rangiora inland to Oxford. Its not just a 10-20% increase, but as in this case its 50-100% more rain than in the city. I got 106mm in Amberley, I know some gauges in the area were 120mm+, but then we get the uplift from the coastal hills, which the Rangiora area shouldnt see.

Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
I seem to have got myself banned for having the absolute gall to point out that they were being alarmist appeared to be hypocrites lol. A highly 'sanitised' comments list on their page this morning, immaturity reigns supreme.

Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
Oh I've been banned a few times and I wasn't even rude haha, just trying to clarify some model data inconsistencies they were giving out - seems to be highly precious but it's so good that they care so much about the residents of Christchurch ringing up yesterday and shrieking down the phone to Metservice when it was always touch and go if Christchurch would meet their warning criteria, I really do wonder if they look at the most aggressive model run from the model that is giving the highest rainfall forecast then just run with that one and base all their ideas around it...not really the best way to conduct a weather forecasting page I wouldn't have thought

Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
That uplift happens around here as well, some farming friends 2 kms east under the hills by the Hurunui pub can see 30-50% more rain than here during moist E -SE rains but similar or less from drier S-SW or NW spillover, amazing the difference in a short distant.TonyT wrote: ↑Wed 21/02/2018 09:08Yes, and this has happened with every major rainfall event this summer.

Re: Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
I challenged Canterbury weather updates over their headline "severe tropical cyclone expected to make landfall in New Zealand" They came back saying their headline was valid. They claim to be a better provider of weather warnings than MetService - this is getting into dangerous territory and could lead to loss of life if people no longer trust official warnings. Weather watch claimed this storm was going to set records for retaining Tropical Cyclone status as far as 40 deg south based on the model they use

In a video they claimed category 1 even 2 on land fall, I think they all struggle for air so to speak.

Re: Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
15 or 20 years ago I was threatened with legal action by Met Service for daring to use the word "warning" in material I sent out to clients. I even got a "visit" from someone to make sure I understood their position. They developed a "voluntary code of practice" which specified how their official warnings could be distributed and which banned anyone else using the term 'warning' on forecast products. I am continually surprised at what some people get away with these days without MetService or the MOT taking a harder line. Do I feel victimised? Possibly. Did I blaze a trail for those who have come along since?

Severe tropical cyclone is officially cat 3 or higher. If people are going to use these terms, they should learn what they mean

How much did those two cyclones cool the Tasman Sea?

Going to have to wait at least a week before satellites ingest data and average it out. Clear skies are needed as well for good quality data.
The last two frames here show the difference in SST anoms and significant cooling as Gita travelled west from Tonga to New Caledonia.

Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
We had 150.1mm all up for this event with the rain finally easing away from about 2pm here.
Waihi river up and the south end of Speechlys Bridge was washed away. There is a photo of it on RNZ Website.
Apart from that nothing much except for a bit of flooding. The wind wasn't much here either just the usual southerly winds associated with this passing low pressure system.

Re: Ex-Tropical Cyclone Gita impacts NZ Feb 18th-21st
The pattern this year has been bringing tropical systems NZs way so I think the early call for Gita to possibly affect NZ was fair.
