Southeasterly 20mph post dawn. Progressively strengthening: 40, perhaps 60mph western summits mid afternoon.
Deteriorating as buffeting and wind chill become very considerable. General mobility may become difficult.
Rain setting in middle of day onwards
Dry most or all morning. Rain then setting in.
Becoming extensive: very little morning
Fragments some higher slopes, but most summits cloud free most or all morning. Deteriorating in rain as cloud fills in across higher slopes, and particularly east Wales patches form above 300 or 400m.
80% at first dropping to 10%
Little or no sun as cloud soon thickens. Excellent visibility before becoming poor in rain.
3C; rising slowly through the day.
Above the summits.
Frequently windy toward and through next weekend with widespread upland gales - possibly storm force - bands of rain and low cloud. Warmer than at present. These conditions are likely to continue well into November as a lengthy series of Atlantic lows and associated fronts cross Britain.
