Overview GPS Navigation Flight Planning Hazard Avoidance Additional Features Hazard Avoidance Sunny Partly Cloudy Mostly Cloudy Cloudy Thunderstorms Rain Freezing Rain Snow Windy Haze Foggy Very Cold Forecast Legend Very Hot Fronts Legend SURFACE PRESSURE This feature displays pressure isobars and pressure centers. The isobars connect points of equal pressure. Pressure readings can help determine weather and wind conditions. High pressure areas are generally associated with fair weather. Low pressure areas are generally associated with clouds and the chance of precipitation. Isobars that are packed closely together show a strong pressure gradient. Strong gradients are associated with areas of stronger winds. Pressure units can be displayed in Millibars (mb) and Inches of Mercury (in). Appendices Index Surface Pressure Data 190-01194-00 Rev.
