On weather maps, what does the symbol L indicate?

Explanation:
On weather maps, the letter L marks a center of low atmospheric pressure. This indicates an area where the air is rising, which tends to form clouds and bring unsettled, often stormy weather. Low-pressure centers are associated with cyclonic wind flow, and in the Northern Hemisphere the winds around a low rotate counterclockwise and toward the center. This symbol is distinct from high pressure (marked by H) and from indicators of wind direction or humidity, which are shown with other map features like wind barbs or dew-point values.
