AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 927 Pm Edt Mon Apr 23 2018
Synopsis.. An area of low pressure across the southeast region will track east toward the mid-atlantic coast through Wednesday. SEveral troughs will sweep across the area around this low, with prevailing offshore flow expected over the waters except in the afternoon with the sea breeze. Another area of low pressure will move north of the waters late Thursday through Saturday, with yet another series of troughs impacting the local waters. High pressure will build north of the region early next week with a transition to onshore flow.

Mostly dry conditions and mild temperatures tonight...

Update
Dry mid level air wrapped around the southern periphery of a
surface low across central ga this afternoon, which limited
vertical growth of diurnally enhanced convection across much of
the local forecast area generally west of the highway 301. East of
highway 301 a pre-frontal trough axis combined with diurnal
instabilty, an upper level short wave trough and the east coast
sea breeze to produce a few distinct clusters and even bowing
segments of storms at times as they approached the east coast and
moved offshore through early evening. Another convergent line was
firing a few storms this evening just wnw of our inland ga zones
and through the next few hours, and as this line gradually
advances ene, it could impact area generally from douglas toward
plant hatch.

Elsewhere, mostly dry conditions expected through the reminder of
the night with passing low clouds under warm wsw flow. Could be a
rouge shower with elevated surface based instability still in
place, but increasing mid and upper level subsidence will greatly
limit precipitation potential overall.

Mild low temperatures will range generally in the low to mid 60s,
with some upper 50s possible inland.

Aviation
Vfr conditions early this evening in the wake of showers and
tstorm activity today. Later tonight area of low stratus in the
eastern gomex will begin to edge inland toward gnv where
restrictions to at least MVFR with SREF confidence of about 50%
with confidence of ifr of about 40-50%. This area of stratus is
expected to nose nne across much of NE fl terminals through 12z
but coverage of low clouds is questionable. At this time trended
toward highest confidence of restrictions to MVFR at gnv around
03z, with other terminals maintainingVFR but with sct low stratus
coverage.VFR conditions expected by mid-morning Tue with
westerly winds and dry conditions.

Marine
Seas were subsiding within the nearshore waters this evening with
the nearshore fernandina beach buoy 41112 measuring 5.2 ft at 830
pm edt and the nearshore st. Augustine buoy measuring 5.6 ft at
822 pm edt. Given persistent offshore flow tonight, will go ahead
and drop the SCA for the nearshore waters and carry exercise
caution conditions through early morning Tuesday. SCA will
continue for the outer waters through early Tue morning, then
will likely be followed with exercise caution conditions Tuesday
due to elevated seas.

Rip currents: moderate risk expected Tuesday.

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.
