I was flying in the Caribbean yesterday evening, live weather, and there were storms. Fair enough, there might have been. But what I saw was very few clouds, at around 3000ft, and the occasional massive lightning shot all they way across the sky, which was mostly clear. I think this would be defined as “Few clouds”.
I didn’t look at the time for one of those sites that shows lighting activity, and I’m prepared to give it the benefit of the doubt, but it’s depiction was distinctly unrealistic. It looked more like some very light showers would be more accurate.
