Ultimately, the pressures associated with very intense hurricanes and very strong highpressure systems in the winter (more than 1050 millibars) are pretty rare. As a general guideline, nearly all sealevel pressures lie between 950 millibars and 1050 millibars, with most sealevel pressure readings falling between 980 millibars and 1040 millibars.

What Is Considered High Barometric Pressure? Reference.com
Normal barometric pressure is between 980 millibars and 1,050 millibars. High pressure systems are also referred to as anticyclones. High pressure systems move in a clockwise motion in the Northern Hemisphere and counterclockwise in the Southern Hemisphere because of the Coriolis effect. The Coriolis effect is a result of Earth''s rotation.
