The following might prove very handy for seascape/landscape photographers who, like myself, long for good clouds in the sky.

I've just become aware of SkippySky Astro-Weather Forecast, which shows a visual map of cloud cover, including percentages, with breakdown of cloud cover (ie, high, middle, low and total).

Check it out.

This could certainly avoid the immense frustration of turning up somewhere to be assaulted with a plain sky which is utterly boring and extremely difficult to photograph when facing the east in the morning.
