Update
Raised wind advisory for the NE fl coast as wind gusts 35 to 45
mph expected as the flow becomes n-ne this morning. Strongest
winds over the next 6-9 hours then a slow decrease the rest of the
day, for now have posted the advisory through 4pm, but may be able
to cancelled early if needed.

Aviation
[through 06z Thursday]
conds have improved toVFR at ssi otherwise widespread MVFR cigs
at NE fl TAF sites except for ifr at sgj. Strong winds from the
north gusting to 25-30 knots will continue along with the low cigs
for the next several hours until improving conds start in the
12-15z time frame as MVFR CIGS become bkn, then scatter out and
becomingVFR at all TAF sites in the 18-21z time frame along with
a slow decrease in the NE winds.VFR conds continue this evening
but cloud cover increases with CIGS returning at around 4000 ft.

Prev discussion [908 pm est]
Near term [through tonight]
Rain showers this evening were moving though coastal SE ga and into
ne fl along and east of highway 301. Behind the front, winds are
shifting from the SW to the NW ushering in colder temperatures.

As the front pushes south of the area late this evening, rain
shower chances should end and skies will begin to clear after
midnight for SE ga and the suwannee valley of NE fl while onshore
northerly flow keeps clouds along the immediate NE fl coast.

Northerly winds will veer to the nne and keep the NE fl beaches a
little sheltered from the coldest air that will occur over inland
areas. A freeze warning is in effect for most of SE ga where lows
will drop below freezing mainly from waycross north and west.

Meanwhile, along the i-10 corridor of NE fl, lows will drop into
the mid to upper 30s with low 40s in north central florida with
coastal NE fl only dropping into the upper 40s for the jax beaches
to the low to mid 50s from st augustine southward.

Short term [Wednesday through Thursday night]
On Wednesday, high pressure moves to our north keeping highs below
average across the entire area. Clouds will remain near the
coast while drier conditions and mostly sunny skies prevail over
interior SE ga and NE fl. North winds will be breezy along the
coast with winds of 20-25 mph with occasional gusts of 25-30 mph
while inland areas will see lighter winds from 10-15 mph, gusting
up to 15-20 mph. High temperatures on Wednesday will rebound only
into the low to mid 50s in SE ga and the mid to upper 50s near
jacksonville and along i-10 with low 60s for north central
florida.

Wednesday evening into Thursday, surface high pressure will move
to our NE which will help to increase the pressure gradient as
an inverted low begins to form over the NE fl coastal waters,
increasing clouds and rain chances for coastal areas. Some
elevated NE winds will continue the possibility for coastal
flooding.

Long term [Friday through Tuesday]
An upper level +pv anomaly will lift northeastward from the north-
central gomex into the southeastern u.S. Early Friday morning.

This low will deepen, forming a low pressure system that will zip
across the area Friday morning and afternoon, lifting off to the
mid-atlantic coastline by Friday night. Wrap around moisture will
allow for lingering rain chances overnight even after this system
moves offshore, but those should clear by Saturday afternoon.

After that, the weekend is expected to be dry and cooler than
normal for this time of year (highs in the low 60s instead of low
70s and lows in the upper 30s to low 40s instead of upper 40s to
low 50s). Temperatures will gradually climb back towards normal
values early next week, with only slight chances for showers
returning with the return of northeast flow (highest chances will
be along the coastline and offshore).

Marine
Winds will surge over our coastal and offshore waters this evening
in the wake of a cold front, with sustained winds overnight and
into tomorrow of 25 to 30 knots and gusts to 34 to 40 knots. A
gale warning is in effect through late Wednesday morning. Winds
will gradually fall tomorrow, but winds over 20 knots could linger
into tomorrow night and seas over 7 feet could last into Thursday
over our offshore waters. There could be brief relief Thursday
into Thursday night, but another low pressure system will sweep
through the area on Friday and could drive winds and seas back up
on Friday night.

Rip currents: strong winds and swell in the wake of a cold front
will drive up surf heights as well as the risk of rip currents.

There is a high risk of rip currents tonight into tomorrow night
along both SE ga and NE fl beaches. This risk will likely be
extended into Thursday. A high surf advisory is in effect tomorrow
for NE fl beaches for surf heights of 7 to 9 feet, with even
higher sets possible.

Hydrology
Strong (25-30 kt) north-northeasterly winds in the wake of a cold
front tonight and tomorrow, combined with a full moon (and
therefore already above normal tides) will lead to coastal
flooding at our intracoastal waterways and along the st. Johns
river. In SE ga and along the st. Mary's river in NE fl, these
tides will run around 1 ft above mhhw. In NE fl along the icww and
st. John's river, these tides will run 2 to 3 feet above mhhw. A
coastal flood statement is in effect today, with an advisory in
effect tomorrow in SE ga and a warning in effect tomorrow in ne
fl.

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.
