Mountain forecast

I don't know, but usually if you click on the two green arrows to expand the entry for that day the "-" disappears. I use that site too but find the wind speeds it shows for the summits are sometimes a bit crazy.

See my post above ...

Come to think of it, looking at that all the lines = none or zero/ground level in this case, so fog it is.

That's strange, a couple of the ones I tried it on did.
