A TOUCH OF WINTER

June 28, 2011

Winter weather conditions are finally arriving over New Zealand.

“Significant snowfalls down to about 600 metres are expected from later Tuesday through to Wednesday morning in Canterbury and Marlborough, with some of the higher roads in these areas likely to be affected,” said MetService Weather Ambassador Bob McDavitt. “Snow is also expected over the central North Island mountains on Wednesday, with the snow level reaching down as far as the summit of the Desert Road.”

MetService has issued a Severe Weather Watch for thundery rain in Hawke’s Bay and Gisborne overnight Tuesday and on Wednesday morning. While rainfall totals are not expected to meet Warning criteria, some intense localised downpours are possible, with rainfall rates briefly reaching 35 mm per hour. This could cause localised flash flooding.

A Severe Weather Watch for strong southeast winds is also in effect. “Some valleys and gorges in Westland and Buller may have wind gusts over 110km/hr overnight Tuesday,” commented McDavitt. “On Wednesday, strong southeasterlies are expected over much of the North Island, with parts of Bay of Plenty and Taranaki possibly having wind gusts over 110 km/hr. Take care on the roads.”

McDavitt went on to say, “The southeasterly winds spreading over New Zealand are cold, and bring with them significant wind chill. In eastern areas of both islands, cold rain over the next day or so could place stress on vulnerable livestock.”

Conditions are expected to ease on Thursday, as a high over the Tasman Sea edges its way towards New Zealand.
