Safety Tips -  Be aware of the weather

 

New Zealand’s weather can change dramatically in a few minutes. Obtaining forecasts for the week, learning to read the signs and interpret weather patterns may minimise your chances of being caught out.

 

Weather has a major impact on trips in the outdoors. An easy and relaxed trip in warm weather can be physically and mentally demanding if the weather turns cold and wet. Strong winds, soft snow, or high rivers may make a route impassable.



Outdoor Safety Code Videos - Part 3: Be aware of the weather 



Learn to observe the weather

High-cloud signs
The wind that you experience is affected by the landforms around you. It may be quite different from the general wind flow associated with the pressure system. You can get some idea of the strength and direction of the general wind flow by observing cloud movement.
Movement of the highest cloud is often difficult to see. Wispy, cirrus clouds, which look like mares’ tails or streamers, indicate strong, high-level winds and are often the first sign of bad weather.

Northerly winds at high levels are usually a sign of bad weather. If a southerly front with associated bad weather has passed through, southerlies with cumulus clouds (fluffy, isolated shapes in a blue sky) indicate a settled period in which trips may be done safely.

Low-cloud sign
The gradual thickening and lowering of the cloud base is an ominous sign. The sun or moon becomes dim or watery as it gradually becomes obscured by the thickening cloud.

‘Hogsbacks’ (smooth, lens-shaped clouds) which form over mountain tops or immediately lee of the tops, are associated with strong winds at that level. As bad weather approaches, they usually become bigger.

This would suggest that you probably need to revise your plans for the next day.
