Poor Visibility

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.

Heavy Persistent Rain

Heavy and persistent rain can lead to drenched clothing and footwear with waterproofs often becoming soaked through, especially if accompanied by strong winds. This can lead to significant loss of body heat and an increased likelihood of hypothermia. Terrain may turn increasingly boggy underfoot while streams can flood and 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.

Thunderstorms

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.

Additional weather information

Meteorologist's view

Likely a wet day on the slopes with waterproofs likely becoming soaked in the heavier bursts. Be aware of navigation issues in the low cloud.

Weather

Perhaps a dry start, but cloud building through the small hours with outbreaks of rain arriving through the morning which may be heavy at times and perhaps persistent over a few hours with a low risk of thunder associated with the heaviest pulses. Best of any dry weather to the east and south of the park.

Chance of cloud-free hill tops

20% to the west, 50% to the east

Low cloud and visibility

Cloud around 500-600 m will thicken through the morning and persist for much of the day, perhaps slightly lower in the west and higher with a few breaks in the east. Visibility generally moderate or poor in rain, or very poor in cloud.

Ground conditions

No recent ground conditions report available.

Mountain weather information

Weather

A band of rain may lie over, or just to the northwest of, the park, although confidence in its exact position remains fairly low at this stage. Should the rain band lie over the park, outbreaks of rain, heavy at times, could persist for much of the day. If it remains to the northwest, fairly dry conditions will prevail with sunny spells. At present, it is more likely that the rain band will stay further to the northwest, with drier and brighter conditions across the park, but with rain more likely into the evening as the band of rain edges east.

Chance of cloud-free hill tops

40% rising to 60% through the day

Maximum wind speed expected

Southwesterly 20mph with gusts of 25-30mph.

Temperature

At 600m Plus 12 Celsius rising to Plus 19 Celsius.
Valley Plus 14 Celsius rising to Plus 21 Celsius.
Freezing level Above all summits.

Low cloud and visibility

Broken cloud may linger around 500 metres at first during the morning, but likely lifting above all summits during the afternoon. Cloud may be lower if rain band lies over the park. Visibility generally good or very good, but poor in any outbreaks of rain and very poor within any cloud.

Ground conditions

No recent ground conditions report available.
