Marine Weather and Tides
Duck Key, 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.

Discussion
Currently
Kbyx detects scattered showers and isolated thunderstorms
throughout the forecast area. Skies over the island chain are
mostly cloudy. Winds over land are east to southeast near 15 mph.

C-man winds, on average, are east to southeast at 15 to 20 knots.

Temperatures are in the lower 80s.

Short term (tonight through Tuesday night)
A trough of low pressure will progress northwestward through the
northeastern gulf of mexico tonight through Tuesday. An atlantic
ridge of high pressure will build across the southeastern united
states Tuesday night. Rain chances in the short term portion of
the forecast will be well above normal for this time of year.

Long term (Wednesday through Sunday)
The aforementioned atlantic ridge of high pressure over the
southeastern united states will shift southward down the florida
peninsula Wednesday, before retreating eastward Wednesday night
and Thursday. A broad area of low pressure may develop over the
northwestern caribbean sea Thursday night. This area of low
pressure could progress northward Friday into the upcoming
weekend. Forecast uncertainty is high Thursday night through
Saturday. Rain chances in the long term portion of the forecast
will be highest Wednesday through Friday.

Aviation
Wet pattern will persist at the eyw and mth terminals. Both

remains poor at this time. Storm motion has increased to 15 knots
or greater, and upstream, in-situ development continues. Both
terminals can expect temporary periods of ifr vis, MVFR cigs,
accompanied by convective wind gusts near 25 knots.

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.
