Marine Weather and Tides
Neptune Beach, 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.

Update
The 12z jax sounding this morning showed moist conditions with
precipitable water values (pwats) near 2 inches. Temperatures
aloft were warm, with the freezing level near 16kft and 500mb
temps around -5.5c. This will keep the severe threat in check,
with the main threat being heavy rainfall. A few strong wind gusts
from downbursts are possible due to precip loading.

The higher moisture values, pwats near 2 inches, extended across
much of the region. Much drier air was along the coast and
extended into flagler county. Slightly drier air was also north of
waycross. Coastal areas and north of waycross will only have a
20% chance of showers storms or less. Deep layered ridging was
located west and northwest of the region. A light north to
northeasterly flow aloft will prevail, and storm motion will be
to the south and southwest. Hi-res guidance indicates that
convection will initiate along the gulf coast sea breeze near the
suwanee valley and east coast sea breeze in southeast georgia
early this afternoon, with the sea breeze boundaries merging
across the interior in the mid to late afternoon. Scattered to
numerous showers storms are expected across the interior, with
storms diminishing in the evening with loss of daytime heating.

Temperatures will be near normal in the lower 90s, except near 90
along the beaches.

Aviation
Vfr conditions will prevail at the regional terminals through at
least 18z. Showers and thunderstorms should converge on gnv and
vqq in the 18z-22z time frame, with vicinity activity possible at
jax, crg and ssi. Light southwest surface winds this morning will
become southeasterly along the coast as an east coast sea breeze
moves inland. Vicinity thunderstorm activity may linger at vqq
and gnv until around sunset on Tuesday.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
