Stratus clouds tend to be featureless, low altitude clouds that cover the sky in a blanket of white or grey.
Height of base: 0 - 6,500 ft
Latin: stratus - flattened or spread out
Stratus clouds are very low-level grey layers or patches of clouds with fuzzy edges. They are the lowest clouds and sometimes appear at ground level in the form of mist or fog. Stratus clouds are a fairly uniform grey or white colour and may be accompanied by drizzle, snow or snow grains. If there are no other clouds above the layer of stratus cloud, the sun or moon may shine through.
