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).

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.
