Onshore flow continues to bring high surf today and high risk
of rip currents through Sunday. . .

Elevated water levels will continue today on the st johns river
basin...

Update
Onshore flow will continue today. High pressure centered over the
carolinas will continue to move slowly to the east, bringing
continued onshore flow with breezy conditions and a few passing
showers, mainly for coastal locations. Very dry air noted in the
12z jax sounding above 850 millibars will help limit the coverage
of any showers to locations east of i-95 to the beaches.

Precipitable water values of less than an inch over interior
portions of SE ga helped to drop low temps down to the mid 60s
early this morning in contrast to low to mid 70s along the
immediate coast where st simons island only fell to 74f.

Stratocumulus clouds associated with the easterly onshore flow
will help keep high temps down along coastal locations with high
temps reaching the lower 80s at the coast with mid to upper 80s
along and west of i-95 for NE fl and SE ga. Winds will remain
slightly elevated at 15-20 mph and gusts to 25-30 mph with
diminishing winds farther inland.

Aviation
Vfr conditions expected with occasional MVFR CIGS vsbys possible
as the onshore easterly flow brings a few brief showers mainly
confined to coastal TAF sites ssi,sgj, and crg. Winds will be
highest at these TAF sites, ranging 10-15 knots with gusts to
20-25 knots. Lighter winds expected at interior locations.

Marine
Strong high pressure to the north of the coastal waters will
maintain a strong easterly flow across the waters today with a
gradually relaxing flow on Sunday into Monday. High pressure will
drop south over the waters early next week with light winds. A
long period easterly swell will continue to move into the area
from several tropical systems over the western atlantic.

Rip currents: high risk of rip currents will continue today along
the coast due to strong northeast flow combining with long period
swells that will impact the surf zone through the afternoon. The
morning surf reports at NE fl beaches still were in the 5-7 ft
range, so continuing the high surf advisory for now.

Coastal flood: water will continue to be elevated in the st johns
river basin reaching action levels, but remaining below minor
flood for most portions of the river. The exception will be the
middle st johns basin along dunns creek. Monday, the pressure
gradient should relax, allowing onshore winds to become lighter.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
