What is a sign that indicates foul weather may be approaching?

Accumulating dark clouds are a significant sign that foul weather may be approaching. As atmospheric conditions change, the formation of dark clouds typically indicates the presence of moisture and potential storm systems. These clouds are often associated with rain, thunderstorms, or other adverse weather phenomena. Observing the sky for these changes can help boaters prepare for potentially hazardous conditions, promoting safety on the water.

In contrast, a rising barometer usually suggests improving weather conditions, rather than deteriorating ones. Clear and sunny skies indicate stability and good weather, while stable wind directions tend to suggest that conditions will remain consistent, rather than signaling the beginning of a storm. By understanding these signs, boaters can make informed decisions regarding their safety and the safety of others on the water.
