Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

|GMZ600 Synopsis For Destin Fl To Pascagoula Ms Out 60 Nm Including Mobile Bay- 927 Am Cst Sat Nov 18 2017 |
Synopsis..High pressure will continue to shift east to the eastern seaboard and western atlantic through Saturday in response to a strong cold front approaching from the west. The cold front will move across the marine area late tonight through Sunday morning leading to a strong offshore flow occurring throughout most of the day on Sunday. Northerly winds and seas will gradually subside Sunday night through early Monday. Frequent gusts to gale force, occurring mostly over the open gulf waters, will also be possible in the wake of the front early Sunday.

High pressure is forecast to keep the weather quiet through the
taf period withVFR conditions. The light and variable wind should
pick up out of the east by late morning, then go light and
variable again tonight. The exception is kapf, where the gulf sea
breeze looks to bring the wind around to the west this afternoon.

short term (today through Monday)
quiet weather with seasonably warm temperatures has continued
overnight, with most areas early this morning in the 60s, with
some 50s over the interior. High pressure will remain dominant
this weekend, bringing lessening winds and dry conditions. Maxima
will reach low 80s with minima in the 60s.
Synoptically, changes in the weather pattern will commence this
weekend as an upper-level longwave trough begins to deepen over
the eastern conus. A moisture-starved and weakening cold front
will cross the region Sunday night, perhaps inducing a few showers
over atlantic waters and immediate east coast, but more likely
precipitation will hold off until Monday as the front stalls over
the florida straights and low-level moisture increases on gusty
northeast winds. Temperatures behind the front, which will
reinforce the relatively low sfc dewpoints across the region,
will only be a few degrees cooler.
Long term (Monday night through Friday)
moisture will increase further Monday night and into Tuesday, as
flow aloft turns southwesterly as shortwave trough digs into the
gulf coast states. There may be enough instability to induce a few
thunderstorms Tuesday afternoon. By Wednesday, the aforementioned
stalled front over the florida straights will have retreated
northward into central florida as a developing warm front. Winds
will turn southerly and more humid conditions are expected. The
pattern becomes fairly complex and models are in high disagreement
on how low-pressure and subsequent cold front will impact south
florida. The GFS solution depicts a southern jet branch shortwave
trough interacting with the northern stream to close off and
deepen an upper-level lopres over the gulf states, moving it
across ga and the carolinas by Friday. This solution would induce
cyclogenesis over the E NE gulf of mexico and track a reasonably
strong surface low across N c fl Wednesday night through|
thanksgiving night, bringing a good chance of showers and possibly
some thunderstorms to south florida, before a cold front brings
noticeably cooler air and drier air into the region for Friday.
Ecmwf, however, keep the jet interaction limited, and projects an
open, highly positively tilted trough cross the region through
the end of the period. In this scenario, surface low pressure
development would be questionable, and precipitation would be
focused along a much weaker cold front that would likely stall
over central and south florida through the end of the week,
keeping warm, humid, and potential wet weather over our region.
high pressure will dominate this weekend, bringing lighter winds
and dry conditions. Sunday night a cold front will move through
the waters, bringing gusty winds and higher seas through Monday
night, and small craft advisories may be needed. Shower chances,
especially over atlantic waters, will increase behind this front.
a moderate risk of rip currents exists on atlantic beaches today
due to moderate easterly winds and a small northeasterly swell.
This swell may persist into Sunday. By Monday, a cold front will
have passed through the region, bringing NE wind of 20 to 25 mph.
This will increase the atlantic coast rip current risk through at

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
