XM WX Weather Features

The Fronts feature displays the lines indicating the leading edge of an air mass that is replacing an existing air mass. This 

feature also displays pressure centers. Pressure centers are represented by a large red “L” for low-pressure centers or a large 

blue “H” for high-pressure centers. Pressure centers represent an area where pressure is measured to be either the highest or 

the lowest relative to the surrounding area.

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.

Indicates a high-pressure center. Similar to a low-

pressure center, a high-pressure center is an area 

where the measured pressure is highest relative to 

the surrounding area. Moving away from a high-

pressure center in any horizontal direction results 

in decreased pressure. Winds flow clockwise 

around high-pressure centers in North America.

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.

Indicates a high-pressure center. Similar to a low-

pressure center, a high-pressure center is an area 

where the measured pressure is highest relative to 

the surrounding area. Moving away from a high-

pressure center in any horizontal direction results
