Brisk westerlies this week

July 1, 2013

This week will see the weather shift up a gear as several active troughs spread across parts of New Zealand in the strong, broad westerly flow across the country.

MetService Media and Communications Meteorologist Daniel Corbett commented,”This week will have a different flavour to last week, with strong to severe gales in places and some heavy rain, as well as much warmer temperatures, climbing well into double figures in places.”

The westerly flow will sweep several active troughs across the southern half of New Zealand, which will in turn tighten the pressure gradient and bring spells of strong to severe gales across many parts of the South Island. This flow will also bring heavy persistent rain to much of the West Coast of the South Island, and MetService has already issued a severe weather warning for this event.

These brisk westerlies will help daytime highs climb well into double figures across eastern parts of New Zealand by midweek.

Across the North Island, the week will have a quieter start but by midweek a departing high will allow wet and windy weather to spread over northern areas.
