A lingering low

July 30, 2012

A deep and active low will bring an unsettled spell of weather to much of New Zealand this week.

Media and Communications Meteorologist Daniel Corbett commented, “This weather system will have quite a bit of punch to it, and it will linger across central and northern New Zealand for several days”.

MetService has issued a number of watches and warnings, and will continue to monitor and update these as this system evolves. An active cold front will bring the risk for some active thunderstorms across the northern half of the North Island this afternoon and again Tuesday afternoon. In addition, a slow moving frontal band will bring further heavy rain across eastern regions of both islands.

Periods of rain will spread down to the east coast of the South Island during late Monday, and remain into the middle of the week. The tight pressure gradient around this slow moving low will also bring the risk for strong to severe gales, mostly in the far south. Rain is expected to fall as snow above 1000 metres in the South Island, which will be welcomed by ski fields but could prove challenging for Canterbury High country farmers and higher route travellers.
