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- 1029 Am Edt Sat Sep 21 2019
Synopsis.. Fresh to strong ene breezes will create hazardous conditions for small craft operations across all south florida waters through this weekend. Occasional gale force wind gusts are possible for the atlantic waters today. Steep waves remain a concern in the atlantic due to wind driven waves and the gradually subsiding long period swell. Small craft advisories continue for all south florida waters this weekend, and small craft operators 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 21, 2019 at 1200 utc... 7 nautical miles east northeast of fowey rocks. 14 nautical miles east of port everglades. 13 nautical miles east northeast of lake worth. 13 nautical miles east of jupiter inlet.

Intermittent showers will continue through much of the TAF period
with a focus from fll fxe southward. Sub-vfr conditions possible
with bouts of ifr lifr at terminals directly impacted by heavy
rain from convection. Gusty ene to E winds will persist today,
lighten some overnight, before picking back up tomorrow morning.

discussion...

today through Monday...

a mid-level anticyclone over the southeast CONUS will support
building high pressure whose axis extends from the south atlantic
states into the gulf of mexico. This regime will drive easterly flow
through the lower to mid troposphere, with winds turning more
southwesterly at jet level while increasing to around 35 kt. An area
of deeper moisture, now evident in moisture channel imagery over the
western bahamas, will be advected towards us today, with the
greatest moisture pooling expected across miami-dade and mainland
monroe counties. This low-level moisture gradient will be traversed
via a low amplitude shortwave impulse today, with increasing
differential cyclonic vorticity advection occurring in concert
with jet-level divergence. This will serve to enhance lift through
the column, while aiding any convection initiated along the low-
level moisture gradient. Given these features in play, the concern
for heavy rain and perhaps localized flooding has increased for
portions of our area today. There is some variation in the
placement of the greatest moisture transport and better theta-e
airmass, leading to uncertainty in which areas may receive the
greatest rain totals. That said, a consensus of the available
convection allowing mesoscale models support a potential area of
heavier rainfall (averaging 2-3 inches and perhaps locally
higher) across a portion of miami-dade county. The mesoscale
details are key here, and we will watch them carefully today. The
main message is to be aware of the potential for localized
flooding rainfall (particularly for urban and poorly drained
areas) across southern portions of our area (mainly miami-dade
and mainland monroe counties) today. The strong pressure gradient
will maintain breezy easterlies today with hazardous beach and
marine conditions persisting.

There remains some difference among the deterministic model guidance
regarding rain coverage on Sunday. The 21.00z GFS continues
advertising a strengthening low-level ridge shunting the best rain
chances into far southern miami-dade county and the keys. In
contrast, the 20.12z ECMWF solution holds the moisture gradient in
place, albeit with decreasing rain coverage and amounts. The 21.00z
nam and global regional canadian model solutions split the
difference with shower chances persisting but with amounts on the
light side. Given the variance in model solutions, will maintain
higher pops through the Sunday morning early afternoon hours across
southern portions of our area with a gradual decreasing trend
through the afternoon and evening. Will defer to wpc guidance for
qpf, keeping the greater amounts towards the far southeast portion
of our forecast area.

A few showers are possible across far south mainland florida on
Monday before high pressure begins building into the area.

Tuesday through Friday...

deep layer ridging dominates much of the region leading to generally
dry and quiet conditions for south florida. A few showers could
enter the picture by late week as low-level moisture increases. The
dry conditions will allow overnight lows to cool slightly, with
upper 60s to lower 70s possible across portions of the interior.

Marine...

fresh to strong ene breezes will create hazardous conditions for
small craft operations across all south florida waters through this
weekend. Occasional gale force wind gusts are possible for the
atlantic waters today. Steep waves remain a concern in the atlantic
due to wind driven waves and the gradually subsiding long period
swell. Small craft advisories continue for all south florida waters
this weekend, and small craft operators should exercise extreme
caution, especially around jetties and inlets.

Beach forecast...

the high rip current risk continues for all atlantic beaches through
at least this weekend. Surf-zone wave heights over 7 feet remain
possible along the palm beach county coast. This may bring localized
beach erosion along with the potential for breaking waves over
jetties and piers. A high surf advisory remains in effect for the
palm beach county coast through Monday morning. Swimmers and
beachgoers are urged to use extreme caution this weekend and follow
the instructions of lifeguards and other public safety officials.
