Which color denotes a Low Pressure area on a Surface Analysis Chart?

Color coding on a Surface Analysis Chart uses warm colors to flag lower pressure systems. Red is used to denote a Low Pressure area, making it stand out quickly and signaling the associated unsettled weather. Cooler colors on these charts are typically used for higher pressure or less active areas, so they don’t indicate a low-pressure center. The key is to read the chart’s legend, and in this chart red marks the low-pressure zones.
