Weather watch: Southern snow is on the way

Time to hunt down the winter woollies - freezing temperatures are on the way, bringing rain and snow to the South Island.

Several low pressure fronts approaching from the Tasman, expected to arrive on Wednesday. They will bring southeasterly winds, rain and lots of snow to eastern areas.

A MetService spokesperson says snow lowering to 300 metres is forecast for Southland, Otago and south Canterbury. This will lower to 200 metres in the afternoon, south of Ashburton. Further north, snow will reach as low as 800 metres.

Invercargill will reach a maximum of 7degC and Christchurch will be only slightly warmer at 10degC.

Alexandra residents will need to have their gloves and mittens ready - temperatures are heading below zero, and later in the week a max of 2degC is expected.

On Tuesday, police urged motorists to take care on frosty southern roads, particularly in shaded areas and bridge crossings.

Emergency services have been busy attending to ice and speed-related crashes in the Dunedin, Southland and Clutha areas.

"Remember to leave a bit earlier, increase following distances, avoid erratic steering movements or heavy braking," a spokesperson says. 

Various sections of road around the southern region have blue cat's eyes, which warn when there are icy conditions.

There are no road snowfall warnings for the alpine passes but many have ice warnings, including Lindis Pass and Porters Pass.

South Island ski fields are reporting blue skies and light winds, with freshly groomed trails.
