Marine Weather and Tides
Sawgrass, 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 Scattered showers and storms currently over southern
counties of NE fl moving SE in area of low level convergence and
instability. Additional storms expected this afternoon with ridge
aloft to the west producing a light NW steering flow. The west
coast seabreeze will push inland reaching the east coast seabreeze
which will be pinned at the east coast beaches. Pwats near 2
inches with dry mid level air may produce isolated wet microbursts
mainly in merging cells this afternoon. Westerly flow will mean
hot and humid conditions including the beaches today with heat
indices reaching the 105 to 109 range.

Aviation Vfr conditions will prevail today outside of scattered
and storms. Have vcts in tafs for mainly 19z-00z time period.

Marine Sw winds will become SE near the east coast by late
afternoon due to seabreeze. Late day storms may reach the waters
by early evneing.

Rip currents: low risk with offshore winds.

NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

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.
