Marine Weather and Tides
Longboat 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.

GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 850 Pm Edt Thu May 24 2018
Synopsis.. Showers and storms moving offshore tonight may result in locally gusty winds and lightning. Otherwise generally light east/southeast winds are expected. Similar conditions are expected tomorrow and Saturday as storms develop inland a push offshore during the evening hours. We continue to Monitor the tropics for possible development with a disturbance as it lifts north of the yucatan peninsula. Regardless, widespread shower and storm activity and increasing winds and seas are a guarantee from late Saturday through Monday. Winds may even approach gale force at times late Saturday through Sunday. Continue to check the forecast frequently as it is likely to change. Lighter winds and seas are expected to gradually build back in for the first half of next week, though the potential for showers and storms will linger.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
