Hi Phil, Can you explain why the windspeeds for the incoming cyclone differ considerably between your rural weather forecast and the Met office warnings?
I have looked at the Whangarei wind forecast for Saturday and Sunday and it is 39km/h with gusts of up to 71km/h max on Saturday and and 40km/h with gusts of 74km/h max on Sunday.
The Met office predicts from 11pm Sat, 11 Apr – 2pm Sun, 12 Apr: Severe gale southeasterlies changing to severe gale southwesterlies during Sunday afternoon, gusting 130km/h in exposed places. Moderate chance of upgrading to a Red Warning.
Since we overlook the sea we do get more rain and wind than Whangarei itself sometimes, so I looked up Taiharuru as well and there the wind is 47km/h with 78km/h gusts.
From past experience I know that they tend to try and cover all eventualities, however this seems to be a big gap this time.
Any ideas?

Hi, is the wind for tomorrow afternoon in North Auckland likely to increase above predicted levels? Are you seeing the cyclone tracking faster than predicted? I see warnings got moved from early Sunday morning to 9pm Saturday.

Hi Phil,
Was just wondering why there was such a large discrepancy in the reported rainfall amounts yesterday. I live in Takapuna, and was monitoring the radar all day. We had a lot of rain but no downpours, just steady rain. Anyway, the rainfall amount recorded towards the end of last night per your Takapuna station was close to 100 mm which seems accurate, but the Northcote station was reporting that 190 mm had fallen just before midnight! Northcote is just 5 minutes away from Takapuna so surely there couldn’t have been such a massive difference when there were no thunderstorms present yesterday in either suburb.

Hi Aaron, not sure sorry – as it’s a private network and so we can’t double check collaborations etc – and of course no/limited public data for verifying. I know when the Tauranga/Mount floods happened earlier this year both Niwa and MetService had two totally different numbers for the event within a fairly short distance – so it is possible some narrow lines of rain clipped one station and not yours. But without knowing the precise set-up it’s hard to be sure.
Cheers
Phil D
