how come the Manukau heads value reported by you Duncan gets bigger and bigger with every post?the winds that gusted ato 160km/h on the Manukau Heads
I thought it was 75 knots (139kmh) on that day?
also the location where the shed that was being errected by a builder that blew down was not far from me....I recorded 110kmh or so gusts (but my Maximum anenometer, which records instantenous gusts, reached ,122kmh) so would have been similar at that location...
(northerlies are not so good at that site, the Signal station building is around the corner a bit in a northerly, WNW winds are the strongest at that site)
