Mexico - April 8th, 2011

The interesting cloud patterns in this image are Kármán vortex streets (or von Kármán vortex streets), repeating patterns of swirling vortices caused by the unsteady separation of flow of a fluid over bluff bodies.

In this case, the bluff body is Socorro Island, a small volcanic island in the Revillagigedo Islands, a Mexican possession lying some 600 kilometers off the country’s western coast. The island rises abruptly from the sea to 1050 meters (3,445 ft) in elevation at its summit. Isla Socorro is a shield volcano.

Hurricane Frank (09E) is passing south of Socorro Island. The center of the system is located near latitude 18.2 North, longitude 111.2 West.

Frank is moving toward the west-northwest near 9 mph (15 km/hr). A turn toward the northwest with a gradual decrease in forward speed is expected during the next day or so. Frank is forecast to turn northward on Saturday.

Maximum sustained winds are near 85 mph (140 km/hr) with higher gusts. Frank is a category one hurricane on the Saffir-Simpson hurricane wind scale. Gradual weakening is expected Friday followed by a more steady weakening on Saturday as frank moves over cool waters.

Hurricane force winds extend outward up to 15 miles (30 km) from the center, and tropical storm force winds extend outward up to 80 miles (130 km). Estimated minimum central pressure is 980 mb (28.94 inches).
