Marine Weather and Tides
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.

|GMZ600 Synopsis For Pascagoula Ms To Okaloosa Walton County Line Fl Out 60 Nm Including Major Area Bays And Sounds- 335 Pm Cdt Wed May 23 2018 |
Synopsis..A light onshore flow will persist through late Friday as a weak surface ridge of high pressure remains across the northeastern gulf of mexico. An east to southeast wind flow is expected to strengthen and seas build over the memorial day weekend in response to a developing surface low tracking northward over the central gulf. Due to the uncertainty with the track and intensity of the low pressure system over the gulf, winds and seas could be higher over the weekend. Stay tuned for further updates on this pattern in the central gulf throughout the week.

Southeasterly flow persisting is keeping the convection west of the

tomorrow with diurnal convection with most of the activity

Late this week into the weekend the forecast is highly dependent on
the tropical disturbance in the western caribbean. Currently the
national hurricane center has a 60 percent chance of development
over the eastern or central gulf of mexico in the next five days.
Models continue to differ on when and where the system will actually
track. The GFS continues to be on the eastern edge of all the
guidance tracking closer to the west coast of florida. While the
ecmwf tracks the system further west into the northern gulf.
Regardless of development and the track of the system an abundance
of tropical moisture will move into the south florida. The moisture
surge will bring pwats above 2 inches across the area. This moisture
will bring an increase in rain chances and a slight chance of
thunderstorms late week through the holiday weekend. There is|
potential for 3 to 5 inches of rain across the region through the
weekend with locally higher amounts. With the potential for
excessive rainfall, this could bring potential flooding issues with
already saturated ground and elevated canal levels. Those with
interests in south florida should monitor developments closely
through the rest of this week and the holiday weekend.

surge of moisture with higher rain chances and an increase in

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. 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.
