A large, multi-centred area of low pressure is expected to bring adverse weather to much of the South Island and western parts of the North Island this week.

One of these low centres should form to the east of the lower South Island,causing an associated front to stall over southeastern districts during Tuesday and Wednesday. This is likely to give copious amounts of rain in these areas.

MetService has issued Severe Weather Warnings for an extended period of heavy rain over Southland, Otago and South Canterbury from Monday night until Wednesday. A brief bout of heavy rain is also likely on Mount Taranaki during Monday afternoon and evening.

“In addition, we can expect significant amounts of snow during this event for the Otago and South Canterbury high country, with around one metre possible above 1000m and lesser amounts above 600m,” commented MetService Weather Ambassador Bob McDavitt. “This snow is likely to provide challenging conditions for any new-born livestock, as well as those living and working at this altitude.”

McDavitt added that during this event southeasterly winds may reach gale force over parts of Southland, South Otago and western areas from the glaciers to Fiordland.

Another low pressure centre is expected to move onto the North Island mid-week, bringing sporadic thundery showers, and some hail. This should be followed by a southwest flow for the days leading into the holiday weekend. At this stage, the outlook for Auckland for Friday’s Rugby World Cup Bronze Final and Sunday’s Final is for west to southwest winds and cloudy spells with the odd light shower.
