Update
Current satellite and sfc analysis shows low to mid level ridge
across central fl area with southwesterly flow. Stronger deep layer
winds located over southeast ga at 10-15 kt... Dropping slightly into
north and central fl to around 5-10 kt. Pwats are lower than
yesterday per jax sounding now to 1.62 inches, in good agreement with
goes data, with increasing moisture toward the northwest into west
and central ga to about 1.9 to 2 inches.

Low level convergence and weak disturbance aloft resulting in a few
showers over the WRN zones but satellite trends and forcing suggest
this activity will fade a bit and not increase rapidly. Overall,
current pops at 20-35 percent over southeast ga and generally lower
chances over northeast fl looks on track. Earlier convective
start look to occur over the WRN suwannee valley area and into
southeast ga, with a later start for northeast fl area especially
east of highway 301 where a minimim in moisture is noted in goes
imagery. For the update... Only slight tweaks to MAX temps expecting
highs in the lower to mid 90s. Kept the slight to chance pops for
southeast ga, and carried a bit more convection this evening over
northeast fl from about the jax metro area southward toward palatka
and eastern parts of marion county. This latter area of convection
may linger around the 23z-03z time frame. Main concerns with
stronger storms continue to be gusty winds and frequent to excessive
lightning.

Aviation
PrevailingVFR expected today. Isolated to scattered showers
and storms expected today... With best chances after about
20z. For now, vc for showers and storms for jax and vqq but may need
to add in this aftn for sgj and ssi based on latest guidance
and radar.

Marine
Southwest flow about 5-10 kt will shift to south and southeast
near 10-15 kt for the aftn and evening hours. Seas about 3 ft or
less today. Have tweaked the forecast for higher winds and
seas by late aftn and into the evening, otherwise forecast on track.

Rip currents: weak east swells and an aftn onshore breeze will allow
for moderate risk of dangerous rip currents for northeast fl... Lower
risk for southeast ga beaches. Surf conditions show about 2 ft or
less and mostly offshore wind early this morning.

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.
