When Does Fog Form In Inlets And Bays - Fog can create hazardous conditions for transportation and outdoor activities. Typically, fog will form during the temperature changes of the early morning or evening hours and can persist for lengthy periods. As the earth’s surface continues to cool, provided a deep enough layer of moist air is present near the ground, the humidity will reach 100% and fog will form. For fog and clouds to appear, the air has to cool down to the point where water vapor turns into tiny water droplets. This type of fog forms at night under clear skies with calm winds when heat absorbed by the earth’s surface during the day is radiated into space. Because the air's saturation point is low due to the cool temperature, the water vapor condenses and a steam fog forms. An upslope fog forms when moist air if forced up a slope. While this is not pure sea fog, it can also be a concern for mariners. The national weather service issues dense fog advisories when fog over water reduces visibility to 1 mile or less. Web when the drier air lies above the moist surface a moisture gradient enables water to evaporate and humidify the air.

Fog can create hazardous conditions for transportation and outdoor activities. Web when the drier air lies above the moist surface a moisture gradient enables water to evaporate and humidify the air. Fog is like clouds, but it happens near the ground instead of high up in the sky. It consists of tiny water droplets or ice crystals suspended in the air, reducing visibility to less than 1 kilometer (0.62 miles). The national weather service issues dense fog advisories when fog over water reduces visibility to 1 mile or less. Typically, fog will form during the temperature changes of the early morning or evening hours and can persist for lengthy periods. An upslope fog forms when moist air if forced up a slope. Web watch for fog that restricts visibility and creates problems in inlets and bays.
