Area Forecast Discussion
National Weather Service Jacksonville FL
1054 PM EST Wed Feb 22 2017

...Windy Conditions Developing Early on Thursday Morning Along
the Northeast Florida Coast...

...High Surf Advisory for Thursday along the Flagler and St.
Johns County Coasts...

.Update...
Late evening surface analysis depicts low pressure (1002
millibars) situated over south Florida. High pressure (1018
millibars) was located east of the North Carolina Outer Banks.
Aloft...a deep mid/upper level cutoff low was spinning over the
Florida peninsula. Dry air continues to wrap into this upper low
from the south, which is resulting in decreasing coverage of
rainfall over all but north central Florida, with bands of
moderate to heavy showers prevailing over the northeast Florida
waters. Mostly cloudy skies tonight will keep lows generally in
the 60-65 range.

Our local pressure gradient will continue to tighten overnight as
low pressure approaches Florida's Treasure Coast. Windy conditions
will develop along the coast from St. Augustine southward during
the predawn hours, with onshore winds of 20-25 mph with occasional
gusts to 35 mph expected through the mid- afternoon hours on
Thursday. Bands of showers may continue to rotate onshore over
mainly coastal northeast Florida through Thursday, but coverage
inland should be isolated to widely scattered in nature, with dry
conditions expected for locations along and west of Interstate 75.
With a deeper and drier northerly flow aloft developing on
Thursday, highs inland should reach the upper 70s, with onshore
winds keeping coastal locations in the lower 70s.

&&

.Aviation...
IFR ceilings are expected to develop at GNV shortly after
midnight, with ceilings falling to low MVFR or IFR during the
predawn hours elsewhere. Periods of showers will continue to
impact SGJ through at least Thursday morning, with MVFR to IFR
ceilings developing during the predawn hours. Surface
northeasterly winds will increase to near 20 knots at SGJ during
the early morning hours, with frequent gusts to near 30 knots
possible. Northeast surface winds will increase to near 15 knots
shortly after sunrise at the Duval County terminals, with ceilings
improving to MVFR towards 15Z. MVFR ceilings at SSI should become
VFR shortly after 12Z as northeasterly surface winds increase to
near 15 knots.

&&

.Marine...
A low pressure center over south Florida will move very slowly
eastward overnight and Thursday to the Gulf stream waters off the
Treasure Coast. The axis of western Atlantic high pressure will
remain situated over the Carolinas, which will result in a
tightening local pressure gradient over our northeast Florida
coastal waters. We have hoisted Small Craft Advisories for the
near shore waters adjacent to northeast Florida until the predawn
hours. A Gale Watch remains in effect for the near shore and
offshore waters south of St. Augustine from the predawn hours
through the mid-afternoon hours on Thursday, and we have expanded
this watch to include the offshore waters south of Fernandina
Beach. Winds will at least occasionally gust to Gale Force in
these waters from the predawn hours through early evening on
Thursday. Seas in the offshore waters will continue to build to
7-11 feet later tonight through Thursday. Further north of this
low pressure center, a Small Craft Advisory remains posted for the
offshore Georgia waters, with caution conditions expected later
tonight in the nearshore Georgia waters. Low pressure will begin
to slowly pivot northeastward on Thursday night just north of the
Bahamas, which will result in a gradually loosening local pressure
gradient. Winds will gradually subside, but seas in the offshore
waters will remain at SCA levels into Friday.

Rip Currents: High risk expected on Thursday along the northeast
Florida beaches, with a moderate to high risk for the southeast
Georgia beaches.

&&

.Coastal Impacts...
A high surf advisory has been issued from Thursday morning through
the evening hours for the Flagler and St. Johns coastlines, where
7 to 8 foot breakers are expected. This high surf may create
beach erosion during times of high tide on Thursday.
