315 am edt Tue sep 26 2017

Short term Today and tonight... A dry NW flow over the area will
provide another sunny and dry day with above normal temperatures.

With light winds temperatures will reach the lower 90s inland... And
mid upper 80s near the coast where an afternoon seabreeze will
develop. Lows tonight will be in the upper 60s lower 70s with calm
winds.

Wednesday and Thursday Hurricane maria will begin weakening off
the north carolina coast, and weak shortwave troughing will hold the
ridge over the lower mississippi back from moving overhead. Overall
dry, offshore or northerly winds are expected midweek. High
temperatures Wednesday and Thursday will reach the mid 90s in most
locations, which will come close to record highs for late september.

Long term (Friday through Tuesday)
Weak troughing will morph into a larger upper level trough or upper low
along the florida gulf coast, and scattered showers and thunderstorms
are possible Friday afternoon, mainly across northeast florida closer
to these dynamics. A cold front will move through the southeast this
timeframe too,though 00z guidance looks like it will wash out before it
reaches far southeastern georgia. Surface low develops later in the
weekend off the atlantic coast and will bring cooler temperatures,
continued rain chances and breezy onshore flow starting Saturday and
persisting through early next week. This event could exacerbate any
still lingering coastal flooding, and bring another round of rough surf
to the beaches.

Aviation Vfr conditions will continue today with light winds.

Marine Advisory for seas will continue offshore into Wednesday
as swells from maria keep combined sea heights elevated. Winds
will be light at near 10 knots through Friday as the pressure
gradient remains weak. Northeast winds will increase Saturday as
models show strong high pressure building over new england and
weak low pressure forming near the bahamas. Advisories will be likely
again this weekend.

Rip currents: high rip current risk today due to long period
(13 sec) swells. Moderate risk on Wednesday as swells decrease.

Hydrology Coastal flood advisory extended through at least
Wednesday for most of the st. Johns river basin as river gauges
still show minor to moderate flooding is still occurring at times
of high tide.

Moderate flooding continues along portions of the santa fe river.

Minor flooding still occurring on the st. Marys river and on the
satilla river east of waycross.

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.
