Stratus Clouds

Stratus Clouds are one of the three basic cloud types. They are low, sheetlike clouds that do not show individual elements. They are typically thick and gray. They are seen in low, uniform layers and rarely extend more than than 5,000 feet above the earth's surface. Fog may form from a stratus cloud that touches the ground. Stratus clouds rarely produces heavy precipitation. However, clouds producing heavy precipitation may exist above a layer of stratus.
