Description:
A moderate danger of windslab avalanching will exist by saturday on slopes lee to the west in the Two thumb range. The potential size of avalanche will increase with proximity to the main divide. If you are planning a visit to the Northern Gammack range or Godley / Macaulay valleys tomorrow it would pay to read the Mt Cook area forecast. There will be a marked difference in conditions from the divide to the eastern ranges.
