Punchy northwesterlies over weekend, colder next week

July 5, 2013

The brisk westerly flow will carry another active trough across the country this weekend with spells of rain and gales.

MetService Media and Communications Meteorologist Daniel Corbett commented, “it will be a wet and windy weekend in many places as the trough moves through followed by colder conditions.”

The northwesterly gales will spread over the country ahead of the main trough later Friday and on Saturday. This will result in another spell of heavy and persistent rain on the west coast of the South Island.

MetService has already issued severe weather watch/warnings for many parts of southern and central New Zealand.

As the trough weakens over the North Island later in the weekend less wind and rain is expected in northern parts. A colder west to southwest flow will feed in further showers for the start of next week accompanied by progressing lower snow levels.

Overnight frosts will be a feature over the South Island early next week.
