GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 408 Am Edt Fri Sep 20 2019
Synopsis.. Interaction between high pressure extending southwest along the eastern seaboard and a tropical wave in the caribbean south of hispaniola is producing a tight pressure gradient resulting in gusty east-northeast winds over the gulf coast waters. Buoys in the eastern gulf are already reporting winds around 20 knots and seas around 5-7 feet. This has warranted the issuance of a small craft advisory for the gulf coast waters through Sunday morning. Winds will decrease to around 10-15 knots on Sunday and continuing through next week as high pressure shifts south allowing for the gradient to slacken. No other marine impacts are expected through the period.

Update Winds have decreased along the coast during the last
couple of hours so have cancelled the wind advisory.

Prev discussion...

Strong and gusty winds along the coast this morning...

Near term (through tonight)
Surface analysis showing strong high pressure wedging from
the mid atlantic into the SE u.S. With a sharpening coastal
trough near the NE fl coast. Obs from both mayport and the
st augustine pier have been showing sustained winds of
around 25 mph and these winds will likely continue into
the mid morning of Saturday before decreasing some as
the gradient begins to relax. Could also have higher
wind gusts to 35 to 40 mph as convergent bands of
showers move rapidly west and come ashore the coast.

Strong high pressure wedging from the mid atlantic into the
se u.S. Builds south and becomes more east west orientated
resulting in low level winds veering and decreasing some
although will still have breezy conditions along the coast.

Convergent bands of showers will also move rapidly west
across the coast before dissipating near the u.S. Hwy
301 corridor.

High temps held in check especially towards the coast
where high temps will be in the lower mid 80s. Temps
out towards the i-75 corridor west will be in the upper
80s. Slightly cooler and drier air works inland tonight
with lows in the mid upper 60s. Low temps along the coast
expected to be in the lower mid 70s.

Short term (Saturday-Sunday night)
Deep layer ridge will remain to the north of the area this
weekend. A tight pressure gradient will continue to produce breezy
easterly winds especially along the east coast. Drier air will
move into the area which will result in a decrease in coastal
showers. Temperatures will be at or slightly below average.

Long term (Monday-Thursday)
Surface high pressure center will be off the carolina coast while
gradually weakening which will decrease the pressure gradient.

Light onshore winds on Monday will become light offshore Tuesday
through Thursday as the surface ridge axis shifts to our south.

Mostly dry conditions will continue through the period as a cold
front stalls over central ga and a mid-level ridge settles over
the fl peninsula. Temperatures will increase to slightly above
average by midweek.

Aviation PrevailingVFR expected. There may be a brief of
mvr from passing showers. Gusty ene winds expected at all
terminals after 14z Saturday.

Marine High pressure builds just north of the waters
resulting in winds veering and decreasing some although
advisory conditions will continue through Sunday as seas
will remain elevated. Will continue to have convergent bands
of showers moving rapidly west across the waters today and
coming ashore the coast before dissipating well inland.

Winds seas improve continue to improve with no headlines
expected by early next week.

Rip currents surf: onshore flow with long period swells
will maintain a high risk for all NE fl SE ga beaches through
Saturday. A high risk is anticipated for Sunday across the NE fl
beaches and a moderate risk for the SE ga beaches. A high surf
advisory will remain in effect for the NE fl coast where
breakers of 6 to 8 feet are expected. Breakers of 3 to 5 feet
expected along the SE ga coast.

Coastal flood: strong onshore flow will continue elevated water
levels along the coast during times of high tide through the end
of the week, about 1 foot above predicted levels. This level of
departure will keep coastal location generally below minor
flooding thresholds, however, the flow will create minor to
possible moderate erosion due to high surf.

Farther inland within the st johns river basin "trapped" tides
will continue to push high tide closer toward minor flood
categories, especially along the banks of the river within putnam
county. Coastal flood statement in effect may need to be upgraded
to an advisory if these trends continue.
