A CHANGE IN THE WIND

May 13, 2011

The mild conditions that have characterised May so far are just about over.

“In the current northerly setup, there’s a couple more troughs expected to cross New Zealand – one late today, and one over the weekend. After that, we’re looking at a major cold southwesterly episode,” commented MetService Chief Forecaster Peter Kreft.

The troughs expected between now and the end of the weekend are likely to make their presence felt. On Friday evening, very thundery squally conditions are possible in Taranaki, on the Kapiti Coast, and in Nelson, Buller and north Westland. Sunday is also likely to see stormy northwest conditions over some northern and central parts of the country.

“For a few days from late Sunday, a very strong southwesterly flow should cover New Zealand,” said Peter Kreft. “While it’s still a little way into the future, it seems likely that many areas exposed to the west or southwest will experience episodes of strong winds next week. For these same places, cold showery conditions are also looking increasingly likely.”

Large southwesterly sea swells are also expected in the New Zealand area from early next week. “At this early stage, MetService expects swells of 5 metres or more on southern and western coasts, arriving about Monday,” commented Peter Kreft. “These are likely to last for a few days.”

With the weather likely to be severe in a number of places sometime over the next week, it will be important to keep up to date with the latest forecasts and warnings online at www.metservice.com, and, for mobiles, at m.metservice.com.
