A grand display of virga, following a day that Martha described as being filled with cirrus uncinus, spotted over Asheville, North Carolina, US
Cirrus spissatus, which is a thick cirrus cloud, is often accompanied by other species of cirrus clouds within close proximation. These clouds can be formed by a conglomerate of cirrus clouds at high altitudes, and separate from that origin, they can also form from the remnants of a dissipating thunderstorm that once had a fibrous top. This example of cirrus spissatus was spotted over Thumrait, Southern Oman, near the Yemeni border.
