Understanding City Forecasts City forecasts appear as standard weather symbols. The forecast is viewed in 12-hour increments for the next 48 hours. Viewing Fishing Information The Fishing view contains current water temperature, surface pressure conditions, and fishing forecasts. From the Home screen, select Information > Weather > Fishing. Using XM WX Weather and Audio Understanding Surface Pressure This feature shows pressure isobars and pressure centers. The isobars connect points of equal pressure. Pressure readings can help determine weather and wind conditions in an area. High-pressure areas are generally associated with fair weather. Low-pressure areas are generally associated with clouds and the chance of precipitation. Isobars packed closely together show a strong pressure gradient. Strong pressure gradients are associated with areas of stronger winds. Pressure units are shown in Millibars (mb), Inches of Mercury (in), and Hectopascals (hPa). Understanding Water Temperature Data The Water Temperature feature indicates the water's surface temperature, as indicated by the legend on the left of the screen. The temperature breaks are indicated by isotherm lines. GPSMAP 400/500 Series Owner's Manual 65
