Strong pressure gradients areassociated with areas of stronger winds.➊➌➋Pressure units are shown in millibars (mb), inches of Mercury (inHg), and hectopascals (hPa).Colored shading ➋, as defined by the legend ➌ in the upper-left corner of the display, indicates the surfacetemperature of the water.Forecasting Fish LocationYou can show areas ➊ that contain optimal weather conditions for specific species of fish.1.
