AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 313 Pm Edt Mon Mar 25 2019
Synopsis.. Southwesterly winds increase tonight into Tuesday ahead of an approaching cold front that will move across the waters during the day Tuesday. Strong high pressure builds well north of the waters late Tuesday through Thursday. Pressure gradient tightens across the waters, with the result being a sharp increase in winds and seas exceeding advisory criteria, with frequent gusts to gale force expected across the offshore waters. Winds and seas will decrease Friday and Saturday as the pressure gradient weakens across the waters.

area forecast discussion
national weather service jacksonville fl
306 pm edt Mon mar 25 2019

Still expecting nor'easter event mid-week... With heavy rain,
breezy windy conditions, and hazardous marine conditions...

Near term Through Tuesday...

initial shortwave trough passes north of the area tonight. Scattered
showers and isolated thunderstorms possible with cold front across
southeast ga, with dry conditions across northeast fl. Low
temperatures will be in the 55-60 range.

On Tuesday, cold front works southward across forecast area as
strong high pressure builds well north of the area. This will set
up a nor'easter pattern for our area. Meanwhile, a second and more
intense shortwave trough will approach the area from the northwest.

Anticipate a band of showers to develop on the cool side of the
surface front over southeast ga during the morning... Extending
south to i-10 corridor in the afternoon. Cloudiness and cold air
advection support cooler high temperatures in the upper 60s to
lower 70s across SE ga, mid 70s i-10 corridor, with upper 70s near
80 further south with later frontal passage.

Long term Tuesday night through Monday...

nor'easter event expected Tuesday night and Wednesday, with breezy
conditions inland, windy conditions coast. Conditions appear
favorable for setup of heavy rain in a band from coastal waters to
somewhere between ponte vedra and flagler county. Models show
35kt low-level jet at 925mb with lift along possible coastal
trough and with upper trough moving overhead. Will need to closely
monitor this potential, as numerical models rarely forecast such
events well. The one saving grace is likely the progressive nature
of upper system and likely southward progression of rain with
time rather than stationary over the same area. High temperatures
Wednesday will only be in the lower-mid 60s across eastern portion
of forecast area, with 65-70 degree temperatures western southern
portion.

Upper trough moves away from the area Wednesday night and Thursday,
while a weak upper ridge builds over the area. Continued northeasterly
flow pattern with a gradual decrease in the pressure gradient.

Latest consensus guidance suggests high temperatures Thursday in
the upper 60s coastal counties... 70-75 further west. Weak upper
ridging will support dry conditions through Sunday, with next
chance of rain coming Sunday night and Monday with next
approaching system. Warming trend expected Friday through Sunday
with high temperatures in the upper 70s to lower 80s over the
weekend. Low temperatures will increase from mid 40s to lower 50s
Friday morning to the mid and upper 50s by Sunday morning.

Aviation Vfr conditions will prevail through the evening hours.

West to southwest winds around 10 knots with gusts to 20 knots
will continue this afternoon, and then diminish to 5-10 knots this
evening. A cold front will push through the area tonight into
Tuesday morning, and a few showers are possible towards kssi
around midnight. Otherwise, dry conditions will prevail. The
southwesterly flow off the gulf may bring in low stratus to kgnv
overnight. The stratus may make its way towards the coastal
northeast florida TAF sites by the morning. Winds will shift to
the northwest Tuesday morning behind the front. High pressure will
then build to the north of the region on Tuesday, and winds will
shift to the northeast at the end of the TAF period at kssi, and
after the end of the TAF period at the other TAF sites.

Marine Issuing gale watch for offshore water, small craft
advisory for nearshore waters, for expected nor'easter event late
Tuesday through Thursday. Winds and seas will quickly increase
behind a passing cold front Tuesday... With advisory criteria winds
and seas late Tuesday afternoon through Thursday. Frequent gale
force gusts are expected across offshore waters, thus a gale
watch there.

Rip currents: moderate risk Tuesday. High risk expected Wednesday
and Thursday with rough surf.

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.
