AREAS AFFECTED: Coastal Nassau; Coastal Duval; Coastal Flagler; Northeast Coastal St. Johns; Southeast Coastal St. Johns; Northern Inland St. Johns; Southern Inland St. Johns; Coastal Glynn; Coastal Camden

DESCRIPTION: Sea fog is developing as low stratus clouds settle to the ground from the coast and intracoastal waters towards I-95 with locations at Craig airfield, Fernandina Beach, and Mayport reporting visibility around 1 mile. The sea fog will occasionally reduce visibilities to under 1 mile through sunset and the early evening hours. Dense sea fog will likely expand inland during the early to mid evening hours, when Dense Fog Advisories will likely be re-issued for all of coastal southeast Georgia and coastal northeast Florida. Motorists should remain alert for sudden changes in visibility this afternoon, particularly along coastal roads such as A-1A in northeast Florida and U.S. Highway 17 in southeast Georgia. If you encounter sea fog while driving in these coastal locations this afternoon, slow down and leave extra distance ahead of you in case a sudden stop is needed.

Nimbostratus Clouds Next Topic: Precipitation

A nimbostratus cloud is similar to a stratus cloud in its formless, smooth appearance. However, a nimbostratus cloud is darker than a stratus cloud, because it is thicker.

Unlike a stratus cloud, a nimbostratus cloud typically brings with it the threat of moderate to heavy precipitation. In some cases, the precipitation may evaporate before reaching the ground, a phenomenon known as virga.

Rain Next Topic: Shelf Clouds

Precipitation in the form of water droplets is called rain. Rain generally has a tendency to fall with less intensity over a greater period of time, and when rainfall is more severe it is usually less sustained.

Rain is the most common form of precipitation and happens with greater frequency depending on the season and regional influences. Cities have been shown to have an observable effect on rainfall, due to an effect called the urban heat island. Compared to upwind, monthly rainfall between twenty and forty miles downwind of cities is 30% greater.
