A strong and very cold southwesterly airstream will bring further snow to low levels in parts the South Island, and west to southwest gales, severe in some places.
This continues to be a significant weather event. Strong winds could make driving hazardous, especially for high sided vehicles and motorcycles. Snow is also expected to affect many higher roads and passes across the South Island, causing disruption to travel.
Also, the combination of snow and strong cold southwest winds is likely to cause stress to livestock. People are urged to take extra precautions, especially those travelling, and to stay up to date with the latest forecasts and warnings for their area.

Heavy snow may disrupt travel in affected areas and could damage trees and powerlines. Cold conditions may cause stress for livestock.
