How windy? (On the Munros)

West to southwest in the range 45 to 60mph, at times 70mph higher tops.

Effect of wind on you?

Walking difficult, or on higher tops at times very difficult, with significant buffeting and wind chill. Some ferocious gusts will run downslope.

How Wet? (Precipitation and its impact)

Drizzly in the west.

Frequent or at times constant drizzle across western hills. Very little of any reaching eastern hills.

Cloud on the hills?

Extensive, tops poking above cloud.

Chance of cloud free Munros?
