Hurricanes spin counterclockwise (like all low pressure centers in the northern hemisphere) because of the Coriolis Effect. Because the equator rotates faster than other areas of the Earth's surface, ...

Hurricanes and low pressure systems do spin counter-clockwise in the northern hemisphere. Tornadoes usually do, though not always. The behavior of the intense thundershowers that produce tornadoes ...
