Hawke's Bay residents who battened down the hatches yesterday as wild westerly winds swept through the region are advised to keep them that way for at least the next three days.
The winds have been created by what MetService meteorologist Daniel Corbett called a board upper level trough which had parked itself high over the country.
It's flow patterns were being driven by activity in the southern oceans, an area he said was the current breeding ground for the country's weather.
"We haven't had a high pressure system visit us for a week or two but there is one set to arrive later in the week."
The spinning, twisting trough over the country was beginning to move to the east.
But until Friday its winds would dominate the weather picture.
MetService yesterday released a severe weather watch for Hawke's Bay, particularly south of Hastings, Wairarapa, Westland and Southland.
Gale westerlies will buffet the regions, with some gusts early this afternoon expected to be severe.
While the mainly westerly winds were more associated with the early spring, Mr Corbett said it was not too unusual.
"It is a typical winter upper level trough; they will occur," he said, adding that while their winds were high so, too, were their temperatures, for the time of year.
"You've been lucky there so far with the temperatures," he said.
"And the way things are looking you'll be doing well again with them."
The long-range MetService forecast is for the "blustery and gusty" westerlies easing by Friday, and sunshine and light winds on the weekend horizon and beyond.
Temperatures will be in the mid-teens.
