High for hazardous conditions at first Wednesday. Medium for the timing and snow level of the front that crosses the area Wednesday evening and night, also for the details of timing transitions between wintry showers and periods of snow and rain thereafter.

Weather hazards

Heavy snow High likelihood Hide detail

Expect snow to rapidly accumulate with deep drifts also possible during windy conditions. Progress will be time consuming and physically strenuous, which will significantly affect the distance one is able to travel on foot. Paths will become hidden and difficult to follow, while very poor visibility during snowfall will make route-finding challenging. A heightened avalanche risk is likely and avalanche reports should be consulted where available.

Gales High likelihood Show detail

Progress will be impeded by very strong winds. Walking will be difficult and strenuous at times with a potential for one to be blown over in gusts. There can be a marked increase in winds through cols or on exposed ridges and summits. Distances often take longer to cover with compass bearings becoming more difficult to follow accurately.

Severe chill effect High likelihood Show detail

Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.

Poor visibility High likelihood Show detail

Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.

Blizzards Medium likelihood Show detail

Blizzards and whiteouts present challenging and serious conditions due to a combination of falling or blowing snow, strong winds and cold temperatures. They can be highly disorientating, often resulting in near-zero visibility with limited or no visual references and no distinction between ground and sky. Cliff edges and cornices may not be apparent, even close up. These conditions require very good navigational skills.

Thunderstorms Medium likelihood Show detail

Lightning is a significant mountain hazard which can result in serious injury or death. Mountain terrain often leaves one highly exposed to lightning strikes. Hail may give unpleasant conditions with torrential rain and localised flash flooding also possible, mainly in Summer months.

Storm force winds Low likelihood Show detail

Walking will be very strenuous with any mobility virtually impossible over exposed ground. There is a high likelihood of being blown over or taken off one’s feet, while even standing up may be impossible at times. Basic tasks such as using a map, eating, putting on extra clothing or communication become extremely difficult away from any shelter.


Hazardous conditions with snow showers and severe gale summit winds at first, though these easing for a time, before periods of snow spread from west during the evening

Snow showers will be more frequent through the morning and early afternoon, bringing blizzard conditions at times and a risk of thunder. Gradually the showers will dwindle late afternoon, however a broad band of snow, will spread from the west through the evening, giving significant accumulations later.

Chance of cloud-free mountain/hill tops at 600m

60% becoming 80% late afternoon, with cloud bases occasionally lowering 450-600m as showers come and go. Becoming nil in the evening as cloud turns extensive above 300-400m.


In showers and later periods of snow very poor bringing hazardous navigational conditions, otherwise good or very good.

Meteorologist's view

Hazardous conditions with severe gales and snow showers by day, and again for the evening as periods of snow and lowering cloud bases spread from west.
