Snow could tie up mountain passes overnight

> From the WeatherWatch archives

Most of the precipitation around New Zealand this afternoon is found about the central North Island.

There are a few showers falling on the West Coast of the South Island, but that’s about it for Mainland precipitation.

That will likely change tonight as another surge of energy and moisture comes ashore.  However, not all the precipitation fall as liquid.

Rain may change to snow in some of the higher elevations.  Falling snow and settling snow could lead to travel problems and for that reason, government forecaster MetService has issued the following Road Snow Warnings.

  • Lewis Pass- Rain is expected to turn to snow before dawn on Monday.  10 to 15cm could settle on the top of the pass with lesser amounts to the lower levels.  Snow should ease during the morning with just some light snow showers possible into the evening.

  • Porters Pass- Rain is expected to turn to snow overnight.  10 to 15cm could settle on the top of the pass before dawn with lesser amounts to lower levels.  Snow should ease during the morning, but further snow showers during the late afternoon and evening may bring another 2 to 5 cm to the top of the pass.

  • Lindis Pass- Snow showers are likely overnight and 2 to 5cm of snow may settle on the top of the pass by sunrise.  A few additional snow showers are likely in the afternoon with up to another centimetre of snow settling.

  • Arthurs Pass- Rain is expected to turn to snow before sunrise on Monday.  10 to 15cm could settle on the top of the pass with lesser amounts to lower levels.  Snow should ease during the morning, but further snow showers are possible into the evening.
