The Fronts show lines indicating the leading edge of an air mass. This feature also shows pressure 

centers.

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. 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.

City forecasts appear as standard weather symbols. The forecast is viewed in 12-hour increments for 

the next 48 hours.

Sea Conditions provide surface conditions including winds, wave height, wave period, and wave
