Weather hazards

Gales Medium likelihood Hide 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 Medium 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.

Heavy persistent rain Low likelihood Show detail

Prolonged exposure to heavy rain can result in drenched clothing and a risk of hypothermia if not wearing good quality waterproofs. Terrain may turn increasingly boggy underfoot, while mountain streams will rapidly rise into spate and may become impassable. There may also be a risk of flooding in valleys or glens. If there is snow cover, a heightened avalanche hazard is possible and avalanche reports should be consulted where available.

Forecast

Heavy rain and summit gales in the morning. Drier and brighter with strong winds in the afternoon.

Weather

Dry but cloudy overnight. Heavy rain spreads west after dawn with a risk of gales over the summits. Rain clears east from around midday to give a mainly dry but breezy afternoon with some sunny spells. Occasional sharp showers likely from mid afternoon and through the evening.

Chance of cloud-free mountain/hill tops at 800m

20% through the morning with extensive cloud above 600m, often down to 300m over southern fells. 90% in the afternoon with well scattered cloud mainly above the summits.

Visibility

Poor through the morning with heavy rain often obscuring neighbouring fells. Becoming very good in the afternoon with distant hills clearly visible outside any showers.

Meteorologist's view

Gusts likely to be around 10 mph stronger through the morning over the higher fell tops. Strong winds and heavy rain will give unseasonable windchill.

Ground conditions

No adverse ground conditions reported on 25 of Jul
