Serious Weather - Cyclone Gita hits the Kapiti Coast New Zealand


Welcome to the Midnight Collective Broadsheet 154
Actively supporting NZ’s endangered wetland birds

This is our third tropical storm in a row, something we’ve been expecting with this endless summer now into a fifth month. Gita caused widespread damage to  Tonga, then circled down through the Tasman Sea to line up the centre of the country.
The calm before the storm - Monday evening mallards  
Fortunately we were only sideswiped here at Raumati Beach with Gita  dropping a little lower south than expected while beginning to break up. 
Running for it. Wetland pukeko with youngster
This still provided an unusual weather pattern from Monday night which we monitored carefully  as the first rains began. It was drizzly overnight but then set in early Tuesday morning so that around 8am we were getting 10mm an hour and expecting severe flooding with the local council advertising sandbags for flood areas.
Not so lucky further south - Slips on the Takaka hill in Nelson - South Island
But then it eased around 10.30am after dropping 30mm and while the Wharemauku rose, it didn’t get much over half full. For 24 hours though, to 6.30 last night there was an eerie dead calm. But then the winds really picked up and there was further rain through the night  which took our total up to 50mm. We were ok here however, though it blew our garden gate down into the drive; but then little damage as we walked around the district this morning. A lot of autumn fruit had fallen early (Thankyou for the bag of pears scattered from a tree in a local lane!!).

The most spectacular event has been the closure of the Expressway after a slip closed the main road further into Wellington. It was like a scene out of The Walking Dead. 
Deserted M2PP expressway - 8am Wednesday morning
But ah what bliss! No vehicle stream as we walked the wetland this morning around 8 when it should have been at its noisy peak.  

More serious questions are raised by all this regarding climate change. This is certainly the hottest, longest and lately, most turbulent summer we have experienced, and it’s not over yet. Fruit is ripening very early. Pears are a month ahead while we were out picking blackberries in early January. They usually come on in early February. And then there are the fungi. 
The media have been running stories on rural areas picking wild mushrooms and these don’t usually appear until late March or April. We too, have been noticing these large fungi blossoming around our wetland areas, presumably as a result of these warm humid weeks. 
We will be watching our coming winter closely to see if theres a flow on from it all.

Track we were listening to while posting this. We are back to Dylan as he set out his guide to the aging, gloomy pessimism that steered the  soundtrack to Wonder Boys    Things Have Changed
People are crazy and times are strange
I’m locked in tight, I’m out of range
I used to care, but things have changed

Storm surge drama at Kapiti NZ



Welcome to the Midnight Collective Broadsheet 153
Actively supporting NZ’s endangered wetland birds

Over the last three days the remnants of cyclone -Fehi- have travelled down the western coast of these islands then crossed from the Tasman to the Pacific coast.  So it has  been a turbulent few days with the muggy, low pressure system traversing the South Island, egged on by a rare blue blood moon.

There has been flooding, tourist strandings, slippages and tree plantation flattenings. Scientists have linked the increasingly wild weather to climate change with flooding on the west coast and major coastal tidal surges.

We are prone to surges here at Raumati Beach with the sanddunes under threat though more spectacularly, they can funnel tidal waves  up into the Wharemauku Stream. The area to about a kilometre upstream, has been rerouted to help control flooding. This steers encroaching waves  underground and though there wasn’t major flooding this time, there has been in the past, with the shopping centre going under water. Our rainfall, which had been threatening  all day  shows why this is of concern. Though the centre of the storm skirted past us dropping a respectable 32 mm on our parched landscape, 20 of that fell in about 30 minutes around six, on the night before these photos were taken.

That wasn't enough to   flood low level housing, but it was scary  all the same with the Wharemauku climbing to about 2/3rds full in  in 20 minutes. But it was the sea breaching inland that caught our attention and here is a photo essay, taken at the next high tide, around 11.30 the following morning with the wind still raucous but the worst now over. 
Sea bulking up at the Wharemauku mouth - this is usually pancake flat and safe for children.

Here it comes - wave funneling through drains kilometre upstream 
And comes
and comes...





This is earthquake country and gives an idea of how a tsunami would behave, careening up this inlet. Though a minor disturbance in comparison, it clearly showed how it isn't the initial wave that is the problem, but the weight of water carried behind it. Further upstream it was still swirling, pushing the still flooding stream back  - the tide reaching further inland than we have previously observed.
Wave continuing its push upstream
around 1.5 kilometres upstream and still going strong
Curiously  we spotted  as much birdlife here, as we have for some time so it must have been stirring up the marine life - and this we observed when for the first time we spotted  a small eel slooping around the excavated channels in the former dunelake area 3 kms away. 
Little Shag surfacing on way upstream
And again - all aswirl in the Wharemauku

Even further upstream a couple of very nervy new generation ducks -
Too early yet to see how much parera genes they are carrying
Track we were listening to while posting this? We are back with The Beatles and a desolately, melancholic John Lennon who is hiding his love away.
Gather round
All you clowns
let me hear you say
Hey!!
You’ve got to hide your love away. 

Update on rare crested grebe discovered at Kaiapoi


Welcome to the Midnight Collective Broadsheet 152
Actively supporting NZ’s endangered wetland birds
This story just got a lot more intriguing. 

We have been lucky to get actual photos of one parent (Crested Grebe), sitting on the floating nest over on the far side of the Kaiapoi lake (away from main road) and the mate out feeding. Difficult to know which is which from this distance as they share the nesting and the feeding.

These shots were taken a week ago but since then the eggs have hatched and the youngsters can now be seen atop their parent’s backs out on the lake (no photos yet but we are keeping our fingers crossed for more).

The intrigue lies in the display seen during our early morning watch. We assumed this was a prelude to mating and the laying of the eggs, but these two are now outed as having been already a couple of  weeks into brooding on the nest. If they were human beings, we would characterise this as a playful early morning display of affection between committed partners, adept at sharing the load; and not an exhibition of behaviour, as our scientific jargon so presumptuously proclaims, solely aimed at ‘reinforcing a bond that will ensure the male's genes will survive him, while reassuring the female that he’ll hang around for the duration’.

So let's make our view very clear. These are emotionally complex and morally competent animals every bit as much as we strive to be; though in their very different way.

Now, how to put an end to all that spurious  tripe…?

Track we were listening to while posting this? Well it was Paul McCartney who knew the answer to this at 19, and  put it down in  Can’t Buy Me Love,  although Lennon must have helped put some backbone into these lyrics. This was the Beatles first big song out here in Aotearoa, in the days when we were pretty much cosseted away from the world as it was…
Say you don’t need no diamond ring
And I’ll be satisfied
Tell me you want those kind of things
That money just cant buy.
