AMZ600 Synopsis For Jupiter Inlet To Ocean Reef Fl Out To 60 Nm And For East Cape Sable To Bonita Beach Fl Out To 60 Nm- 312 Am Edt Fri Sep 20 2019
Synopsis.. Substantial swell combined with very breezy northeast to east winds will produce rough seas across the atlantic waters, especially over the gulf stream where wave heights may exceed 10 feet through this weekend. Strengthening northeast to east winds are also expected to create hazardous marine conditions over the gulf waters and lake okeechobee through the remainder of this week into this weekend. Small craft advisories are in effect for all of the south florida waters. There is some potential for occasional gusts to reach near gale-force over the south florida atlantic waters for Friday into Saturday. Also, small craft should exercise extreme caution especially around jetties and inlets.
Gulf stream hazards..SEas of 8 to 12 feet are expected. The highest seas are expected off the palm beach county coast, but at least occasional seas in this height range are possible elsewhere in the gulf stream. Extreme caution is advised for mariners. The approximate location of the west wall of the gulf stream as of sep 19, 2019 at 1200 utc... 11 nautical miles east southeast of fowey rocks. 12 nautical miles east southeast of port everglades. 6 nautical miles east northeast of lake worth. 11 nautical miles east northeast of jupiter inlet.

Discussion
Today and tonight...

south florida will be located between expansive mid-upper ridging
extending from northern mexico into the ohio valley and humberto
associated troughing over the western north atlantic ocean.

Surface high pressure will strengthen from the lee side of the
appalachians through the south atlantic states while a tropical
wave advances through the western caribbean sea. A pronounced low-
level pressure gradient will ensue between these surface features
resulting in brisk easterly winds averaging up to 25 kt at times
along the atlantic coastal interface. Wind profiles through 850 mb
suggest that gusts exceeding 30 kt are also possible over the
local waters and east coast metro areas as well. It still appears
that we will remain below wind advisory criteria (30+ mph
sustained winds and or frequent gusts >35 mph over 3 hours or
more), but we will continue to monitor the latest data and
observations in case deeper mixing becomes established. The
easterly flow should advect a pocket of low-level moisture
(characterized by precipitable water values > 1.5 inches) across
our area today resulting in fast-moving scattered showers and a
few thunderstorms. Precipitation chances should be fairly uniform
across the area today given the fast flow in place, with greater
coverage focusing on the east coast metro and atlantic waters
overnight. Given the rather strong winds aloft it shouldn't take
much for gusty winds to accompany any of the stronger showers and
storms. Highs should average between about 85 and 90, with the
warmest readings over the western interior and gulf coast regions.

Lows will dip into the lower to mid 70s inland, with upper 70s to
around 80 along the coasts.

Saturday and Sunday...

a low-level trough is forecast to be in the vicinity leading to an
increase in shower and thunderstorm coverage, particularly on
Saturday. By Sunday, some of the deterministic guidance shifts the
trough axis farther to our south thus decreasing rain chances for
northern portions of the area. Attempted to represent the greater
spread in model solutions during this period with widespread pops on
Saturday, but with a more pronounced north to south gradient across
the area on Sunday. Given strong low-level ridging across the south
and mid atlantic states, the strong pressure gradient will be
maintained with breezy (and at times gusty) easterly flow
persisting. Temperatures will remain seasonal with highs perhaps a
touch cooler than on Friday.

Monday through Thursday...

mid-level ridging should strengthen from the southeast CONUS into
the gulf of mexico early in the period with the ridge center
shifting towards the carolinas by late week. This should result in
mostly dry and subsident conditions for the early portion of the
week as the low-level trough shifts farther to our south. There may
be enough moisture for a few showers to impact far southern portions
of our area however. As the mid-level ridge re-orients farther to
our north late in the period low-level moisture return should
commence with shower chances increasing by late week into the
weekend.

Marine
Fresh to strong ene breezes will create hazardous conditions for
small craft operators across all south florida waters through
this weekend. Occasional gale force gusts are also possible for
the atlantic waters from today into Saturday, although they
appear to be too infrequent for a gale watch at this time. Steep
waves are also anticipated over the atlantic waters due to the
residual swell and winds. A small craft advisory remains in effect
for all waters (including lake okeechobee and biscayne bay), and
small craft should exercise extreme caution, especially around
jetties and inlets.

Aviation
Vfr conditions and breezy ene winds are expected through the
period with scattered showers across the east coast.

Beach forecast
A high rip current risk continues for the atlantic beaches due to
strong onshore flow. This risk will persist through at least this
weekend, and potentially into next week as well. Surf-zone wave
heights over 7 feet are possible through this weekend for waters off
the palm beach county coast, possibly leading to localized beach
erosion. A high surf advisory remains in effect for this area
through this weekend. Swimmers and beachgoers are urged to use
extreme caution this week and follow the instructions of lifeguards
and other public safety officials.

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.
