Posts succumbed to Localised Extreme Weather Event - !

Windy as, factual as, sang the Tui.

(Bold emphasis added by blog editor)

It never fails to amaze me how gullible people can be. Aurora seem to be suggesting that the four poles that fell in Alexandra were the victim of high winds.
Richard Fletcher's lack of background in powerline engineering might explain any ignorance on the topic but it seems to me that it wouldn't absolve him from seeking decent advice. So before you read the stupid, but predictable, excuses that I'm sure are coming you might like to consider this:
According to the Council owned weather station located at Molyneux Park in Alexandra, 500 metres away from Netball courts, the peak wind gust for the day was measured at 78.5 km/h = 22 m/s > 301 Pa (Historic Design load 850 Pa).
Let me put it as simply as possible for you Richard, the pole fell under loading that was a fraction over a third of the load it was designed to withstand.
The pole should have laughed at the gusts, instead it screamed all the way to the ground.
