Which describes an altocumblus clpud?

Altocumulus clouds are mid-level clouds that typically form between 2,000 and 6,000 meters (6,500 to 20,000 feet) in the atmosphere. They appear as white or gray patches, often with a wavy or rippled texture, and can cover large portions of the sky. Altocumulus clouds may indicate fair weather, but their presence can also signal an incoming weather change, particularly if they thicken or develop into altostratus clouds.
