Marine Weather and Tides
South Daytona, FL

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

AMZ500 Synopsis For Flagler Beach To Jupiter Inlet Out To 60 Nm- 436 Am Edt Fri Jun 22 2018
Synopsis..The axis of the atlantic high pressure ridge will remain south of the local waters through Saturday before drifting into north florida early next week. This will generate a light to gentle southerly breeze across the area with continued benign sea conditions. However, increasing moisture will bring a return to offshore moving storms in the afternoon and evening on Saturday.
Gulf stream hazards..None. The approximate location of the west wall of the gulf stream based on the real time ocean forecast system as of Tuesday june 19th. 40 nautical miles east of ponce inlet. 29 nautical miles east of port canaveral. 23 nautical miles east of sebastian inlet. 15 nautical miles east of fort pierce inlet. 9 nautical miles east of saint lucie inlet.

Discussion
Current... Surface and h85 ridge axes are well south of the CWA early
this morning, with low to mid level westerly flow in place areawide.

Upper level ridge remains over the central peninsula while the mid
level axis has sagged south a bit toward lake okeechobee. While
radar remains echo-free over land, there is quite a bit of leftover
debris clouds from Thursday's convection lingering overhead both the
northern and southern cwa. 7z 3am temps were quite warm, in the u70s
to around 80f.

Today-tonight... Synoptic setup looks to keep the status quo over
the next h24, which will once again favor the interior and eastern
side of the peninsula for scattered to numerous (50-60 pops) diurnal
showers and storms this afternoon into early evening. One difference
today is the absence of the weak mid level vort lobe and attendant
showers low level outflow boundary that was in place early yesterday
morning. This should allow convection to initiate later, which in
turn should let MAX temps reach the l90s areawide (not low-side bust
like they did across the north Thursday). Strong storms possible
once again, although potential for svr wind hail thresholds to be
reached should be tempered by the ridging aloft.

A few lingering evening showers storms should dissipate or move
offshore before midnight. Lows a degree or two either side of 75f.

Sat-sat night... A large storm system over the mid west oh valley
will lift acrs new england under the influence of a fairly stout
zonal jet pattern. As it does, it will ride over the NW flank of the
bermuda ridge, keeping axis surpressed over south fl. A light but
steady wrly flow will prevail over central fl thru the h100-h70 lyr
that will focus diurnal precip over the ERN peninsula. Forecast pwat
values in the 2.00"-2.25" range will keep pops in the likely
category areawide, a little higher over the space treasure coasts
and lake-o region due to higher moisture content.

Overall instability is on the modest side as fcst h70 temps btwn 8-
9c and h50 temps arnd -7c yield mid lvl lapse rates btwn 5.5-
6.0c km, so svr wx threat will be low. Primary concern will be h85-
h50 mean flow arnd 5kts that will result in slow storm motion that
will enhance the threat of LCL heavy rain. MAX temps within 5f deg
of climo avgs... U80s along the coast and l90s inland. Min temps in
the l m70s.

Sun-sun night... Wx pattern will shift as the storm system over new
england continues acrs the canadian maritimes, allowing the bermuda
ridge axis to lift into north fl. H100-h70 mean flow will shift to
an easterly component that will focus diurnal precip back to the wrn
half of the peninsula. Moisture will remain plentiful as upstream
mean rh east of the bahamas is running btwn 70-80pct thru the h100-
h70 lyr, mean h85-h50 rh btwn 50-60pct. However, with the east coast
seabreeze expected to form early, precip chances along the coast
will diminish to arnd 50pct. Higher heating potential inland plus
the easterly steering flow will keep pops over the interior counties
arnd 60pct. No sig change in airmass... MAX min temps will be on the
same order as Sat with u80s l90s and l m70s, respectively.

Mon-thu... A large anticyclone will press out of central canada en
route to the mid atlc coast thru the middle of next week. This will
push a weak frontal trof into the deep south, possible as far south
as the fl panhandle before washing out. While some disagreement
continues btwn the ECMWF gfs solutions, the end result likely will
be a weakening of the WRN flank of the bermuda ridge axis. This in
turn will produce a weak pgrad thru the h100-h70 lyr that will make
it difficult to time seabreeze formation and subsequent diurnal
precip. No major change in available moisture appear on the horizon,
though the possibility of high rain chances will increase if a
stronger trof dvlps. However, given how far out in time this is,
don't want to stray too far above climo... Will cap pops at 50pct.

Aviation Scattered to numerous afternoon shra TS expected once
again near all the local aerodromes. For the upcoming 12z package,
plan to go with an earlier onset time of 2-hour tempo groups for the
interior aerodromes (18z-20z), with 20z-22z for the dab-sua coastal
corridor.

Marine Today-Saturday... Ridge axis over south fl will generate a
light to gentle W SW flow acrs the LCL atlc, backing to S SE by late
this afternoon, and a few hours earlier on Saturday afternoon as the
east coast sea breeze dvlps, then back to S SW arnd midnight as the
land breeze circulation kicks in. Seas AOB 2ft. Sct nmrs tsras
moving offshore in the late aftn.

Sun-sun night... Bermuda ridge axis will lift acrs central fl en
route to the fl panhandle. Light and variable winds at daybreak,
shifting to a light to gentle E SE breeze as the LCL atlc gains the
srn flank of the ridge. Seas generally AOB 2ft... Up to 3ft in the
gulf stream north of CAPE canaveral. Chc of tsras thru the day, slgt
chc overnight.

Mon-tue... Weak ridging over north fl will maintain a light to gentle
srly breeze, meandering btwn S SE in the aftn evng hrs and S SW in
the overnight mrng hrs due to the land sea breeze circulation. Seas
aob 2ft nearshore and 2-3ft offshore. Chc tsras each day.

Hydrology The st johns river above lake harney near geneva is
forecast to remain fairly steady at current levels, staying above
action stage and below flood stage through early next week.

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.
