Update A gulf coast dense sea fog bank along the west coast of
florida has moved north and northeast with light southwesterly
flow. This fog is just upstream of the suwannee valley and just
has started to encroach the western part of suwannee county this
mid evening which is evident on the goes-16 night-time
microphysics contrasts. Hence has put out a dense fog advisory
for columbia, gilchrist, hamilton, and suwannee counties this
mid evening through 10 am. Then the fog will continue to advect
during the post mid-night hours into clinch, ware and echols
counties. As the nocturnal hours progress into the pre-dawn hours
fog is expected to overspread most areas toward the coast and then
nearshore waters. Will watch the progression of the fog advection,
for potential additional advisories downstream, east of 301. The
hrrr hourly model runs continue to show this trend.

A low chance of showers across SE ga for Sunday with mostly
cloudy to partly cloudy skies across NE fl once morning fog and
low stratus begin to lift and break apart. The cold front will
shift west more as a backdoor cold front with NE flow pressing
down the local atlantic coast through Sunday afternoon as high
pressure builds NE of the region.

Aviation mainly prevailingVFR under light ssw flow 5-8 kts
for area terminals this evening. Low stratus and fog are starting
to encroach the suwannee valley. As the night-time hours
progress low stratus and fog will cotinue to further advect
inland from the gulf coast region bringing restrictions from gnv
to vqq first between 05-08z where there is elevated confidence of
lifr and vlifr conditions. Restrictions of ifr expected to impact
the coastal terminals after 09z through 14-15z Sunday. Winds will
transition to NE through Sunday, impacting ssi first by late
morning, then the wind shift progressing down the coast into the
afternoon which could bring sea fog lingering over the atlantic
inland during Sun evening potentially impacting sgj.

Marine Wsw winds this evening ahead of the approaching cold
front. Fog advection from the gulf will affect the nearshore
waters during the pre-dawn hours into the early morning daylight
hours. There might be a temporary abatement of the fog over the
near-shore between 10 am and 1 pm. This fog will likely re-
settle in over the nearshore waters during the afternoon hours
over the adjacent waters as onshore flow develops. The cold front
will slowly settle across the local waters Sunday as high pressure
builds northeast of the region. Onshore flow persists through
this upcoming week as high pressure dominates northeast of region.

Headlines are not expected this forecast period.

Rip currents: low risk Sunday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
