Strong winds and isolated downpours are expected across the country today.
Strong winds from the north-east are blowing across a number of regions today with gusts to gale-force around some exposed areas, Weather Watch head analyst Philip Duncan said.
He said the nor'easter could cause isolated power cuts, although winds were "well below damaging today".
Strong gusts are possible around the ranges in the south and coastal areas in the north, he said.
Winds will gradually ease throughout today and this evening as the large high continued to slowly track eastwards away from the country, he said.
