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- 741 Pm Edt Wed Mar 22 2017
Synopsis.. Generally good boating conditions will continue into early Thursday with seas 4 feet or less and north/northeast winds under 15 knots. Beginning late Thursday, marine conditions will rapidly deteoriate as a weak frontal boundary moves across the region with scattered showers. In the wake of the frontal boundary, hazardous marine conditions for small craft are likely with increasing northeast flow and seas 7 feet or greater, especially for the atlantic waters. Hazardous marine conditions will also be possible for the gulf waters, lake okeechobee, and biscayne bay as well. Hazardous marine conditions, especially for the atlantic waters, are expected to continue through much of the weekend.
Gulf stream hazards..None. The approximate location of the west wall of the gulf stream as of mar 21, 2017 at 1200 utc... 12 nautical miles east southeast of fowey rocks. 18 nautical miles east of port everglades. 15 nautical miles east of lake worth. 18 nautical miles east southeast of jupiter inlet.

Discussion
Northeast wind surge behind frontal boundary will produce
hazardous boating conditions into this weekend...

this evening-overnight... "back door" frontal boundary, preceded by a
n-ne wind shift, will drop south into the northern CWA early this
evening, then push rapidly south across the remainder of the area
prior to sunrise. NE wind surge, coupled with a respectable frontal
moisture band, will increase low level mconvg, with showers breaking
out initially over the volusia county atlantic waters, then spread sw
across the central and southern cwa/maor. The 00z ecs MOS (aob 20
percent) continues to show much lower pops than the mav/lav/met (50-
70), and thus the forecast is shaded toward the higher numbers given
the seemingly favorable low level synoptics. After an initial post-
sunset drop, temps will steady out and perhaps rise some late as
wind surge produces well mixed boundary layer. Mins will range from
the l60s well inland to the u60s along the barrier islands.

Thursday... Frontal moisture band will continue sagging southward,
reaching south florida by afternoon. Premise for scattered showers
continue to look solid, with highest pops across the southern third
cwa, owing the boundary moving through that area by the afternoon.

Expect widespread clouds with breezy to windy ene flow, especially
along the coast. The gusty onshore flow will hold MAX temps down
into the l70s along the volusia/brevard coasts, and the m-u70s from
the treasure coast to the saint cloud-orlando-sanford metro area to
the kissimmee river.

Fri-sat... A strong a well stacked h100-h70 high pres ridge centered
over the upr midwest will be shunted to the mid atlc coast/west atlc
by a 100kt h30-h20 jet streak digging just ahead of it over the
great lakes. Tight low/mid lvl pgrad ahead of the ridge will
generate a brisk NE flow that will push the "back-door" cold front
into south fl by daybreak fri. Precip chances will linger over
central fl Thu night, but dry air advection on the backside of the
frontal trof will drop pwat values to arnd 0.75" by daybreak fri,
bringing an end to this next precip event.

Meanwhile, a short wave trof over the wrn CONUS will lift into
canada and ride over the NRN flank of the ridge, shunting its
trailing axis into north fl. H100-h70 winds will veer to the e/se by
sunset Fri as the ridge pushes into the W atlc. Low/mid lvl
subsidence will increase as it does... Model soundings suggest the
base of the inversion will drop down to the h85 lvl, effectively
capping the airmass well blo 10kft. Isold nocturnal shras psbl over
the gulf stream, but the combination of dry air advection and a
surpressed airmass will keep precip chances out of the fcst for most
of the cwa.

The onshore flow will produce mild temps along the coast with mrng
mins in the l/m60s, aftn maxes in the m70s. Marine influence will
be slightly diminished over the interior with mrng mins in the
m/u50s, aftn maxes in the u70s/l80s.

Extended... (prev disc) despite a fairly amplified mid/upper level
pattern over the conus, weather conditions over the peninsula will
remain rather benign through early next week. Expansive high
pressure will build into the western atlantic over the weekend with
its trailing ridge axis settled to our north. Pressure gradient
relaxes in response while still maintaining a long fetch of e/ese
winds off the atlantic. Moisture levels appear to low enough to
maintain a relatively dry forecast through the period. Temps
gradually warm from the mid/upper 70s Fri to more widespread 80+
readings into early next week, though coastal locations will remain
a few degrees lower given the onshore flow.

Aviation Vfr/skc giving way to MVFR CIGS (bkn020-025) and vsby
reductions in scattered atlantic showers, reaching INVOF dab by 02z,
lee-sfb-tix to mco-ism 04z-06z, then over the space/treasure coast
aerodromes through 09z. NE winds expected to gust to around 25kt or
so on Thursday from mid morning onward.

Marine Overnight-Thursday... Well-advertised NE wind surge will
push SCA conditions s/w across the adjacent atlantic overnight,
mainly north of sipf1. The 12z nwps looked reasonably close to the
preferred-as-of-late 4km wnawave. Winds will reach 20-25kt/gusty
with seas as high as 9ft offshore volusia county by sunrise
Thursday, building further to 7-9ft near shore and 9-11ft offshore
by Thursday afternoon.

Friday-Saturday... Hazardous boating conditions will continue into
the weekend as a strong ridge axis moves off the mid atlc coast and
into the W atlc, trailing its axis into N fl in the process. Tight
pgrad will produce a fresh to strong e/ne breeze on fri, diminishing
to a moderate to fresh e/se breeze on Sat as the ridge gradually
weakens over the atlc waters. Seas 6-8ft nearshore and 8-10ft
offshore on fri, subsiding to 5-6ft nearshore and 6-7ft offshore by
early Sat aftn.

Sunday-Monday... Conditions will slowly improve into early next week
as the WRN flank of the ridge is eroded by a storm system expected
to lift up the ms valley into the great lakes region. The position
of the ridge axis will remain over north fl, extending east toward
bermuda, resulting in a long easterly fetch over the SW atlc. This
will push a long period swell into the east fl coast. Overall
conditions will remain marginal to poor with a gentle to moderate
e/se breeze, seas 5-7ft on sun, subsiding to 4-6ft north of
sebastian inlet and 3-5ft south of the inlet on mon.

Fire weather Thursday-Monday... Hi pres will build over the W atlc
and gradually erode as its axis drops into north fl. Brisk e/ne
surface/transport flow thu-fri will veer to the e/se by daybreak
sat, then will gradually diminish into early next week. The extended
pd of onshore flow will all but ensure min rh values remain abv
critical lvls thru the upcoming weekend.

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.
