Marine Weather and Tides
Port St. John, 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.

Boating conditions will then deteriorate over memorial day weekend, with the development and northward movement of a tropical low pressure system over the eastern gulf of mexico. Expect increasing winds and building seas, with increasing chances for squally showers and isolated lightning storms.
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 Monday may 21st. 38 nautical miles east of ponce inlet. 28 nautical miles east of port canaveral. 23 nautical miles east of sebastian inlet. 14 nautical miles east of fort pierce inlet. 8 nautical miles east of saint lucie inlet.

Discussion
Rap40 analysis shows the WRN flank of the bermuda ridge axis has
been disrupted by broad frontal trof over the carolinas deep south.

This has resulted in a southward shift of the ridge axis into
central fl, creating a sfc low lvl pgrad that is roughly parallel to
the orientation of the fl peninsula. Steady SE flow prevails thru
the h100-h70 lyr will push increasing moisture in from the
bahamas... Evng raobs measured pwat values increasing from arnd 1.75"
at ktbw to 2.00" at mynn, while h100-h70 mean rh increases from 60-
70pct along the i-4 corridor, to btwn 80-90pct over the NRN bahamas.

Lcl wx radar network shows diurnal convection concentrated along the
big bend region and moving nw... Only a few low-topped shra in the
gulf stream.

Increasing precip chances overnight as the low mid lvl moistures
works its way into central fl. However, strength of the h85-h50
steering flow is blo 10kts, resulting in slow precip motion. Any
shras that form will therefore have to spend a longer time over the
cooler shelf waters, limiting the potential for measurable precip to
the coastal zones with pops blo 50pct.

Aftn fcst package looks good with chc shras incrsg from slgt chc
thru early mrng to chc along the space treasure coasts in the
predawn hrs. Min temps will be near the current sfc dewpoints in the
u60s l70s.

Marine
Troffing over the carolinas deep south has disrupted the WRN flank
of the bermuda ridge axis, resulting in a somewhat loose pgrad over
the LCL atlc. Favorable boating conds overnight as the east-to-west
pgrad generates a light to gentle E SE breeze. Seas 2-3ft nearshore
and 3-4ft offshore. Chc of shras thru early morning, bcmg a chc of
shras and a slgt chc tsras in the predawn hrs.

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.
