Weather Alert in Florida
Special Weather Statement issued March 3 at 5:41PM EST by NWS Jacksonville FL
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.

A fractus cloud (scud) is a fragmented, tattered cloud which has
likely been sheared off of another cloud. They are accessory clouds, meaning they
develop from parent clouds, and are named in a way which describes the original
cloud which contained them.
Fractus clouds which have originated from cumulus clouds are referred to as
cumulus fractus, while fractus clouds which have originated from stratus clouds
are referred to as stratus fractus. Under certain conditions a fractus cloud might
merge with another cloud, or develop into a cumulus cloud, but usually a
fractus cloud seen by itself will dissipate rapidly.
They are often observed on the leading and trailing edges of storm clouds,
and are a display of wind activity.

Weather Topic: What is Graupel?
Home - Education - Precipitation - Graupel
Next Topic: Hail
Graupel is a form of precipitation that is created by atmospheric conditions
which cause supercooled water droplets to contact snow crystals and freeze to
their surface.
Sometimes known as soft hail or snow pellets, graupel is delicate and easily
destroyed by touch. Whereas hail usually falls during severe weather, graupel
doesn't require such conditions to form, and can form in mild precipitation
similar to situations which produce snowfall.
