of the gfs/nogaps models do like to make extreme predictions

stiil, keep an eye on the developing system over queensland/north tasman
it might miss the boat though

Not here there have been sunny periods but Rain in between up here What happened to your southerlies in WN that used to frequent in the 60's and 70's

What are the prospects for action weather here in the next few days? Good, or fading?

Sunny dry month here so far, and. quite mild. SE storm for this w/end in earlier prognoses? - sounds like bollocks!

I don't mind this "inaction" at all.

Don't have objective data on hand about windflow directions but I suspect that by comparison with those times we're getting more SW quadrant winds and fewer SE quadrant winds. I do know that annual summary reports ("Meteorological Observations", Met. Misc. Pub. 109) stated that from 1974 to mid-1980 there was some degree of easterly anomaly over the NZ region. One of the ways this may have manifested itself could be the opposite to the above - more "SE" and less "SW". The "El Nino-favouring" decadal oscillation phase from about 1977-1998 I suspect would tend to reverse this. I think windspeeds here have dropped a little anyway - max. gust data (1972-present) support this. But one definitely feels that southerly events are less common and mostly less severe - the odd big storm gets a lot of publicity partly because people are much less used to them now!?

Yep, I recall the big southerly blows being a lot more common when I was kid. Of course that could be selective memory at work, but I don't think so.

I think to terminate this large posting started by Gary in Omarama, that judging by the weather today, this place has officially, died

Is there a "ghost" smiley?
