Indicates a low-pressure center. A low-pressure center is

an area where the measured pressure is lowest relative to

the surrounding area. Moving away from a low-pressure

center in any horizontal direction results in increased

pressure. Winds flow counterclockwise around low-

pressure centers in North America.

center in any horizontal direction results in decreased
