Marine Weather and Tides
Siesta 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- 906 Pm Edt Fri May 25 2018
Synopsis..Winds will generally remain 15 knots or less through tonight with spotty showers. This will rapidly increase late tomorrow through Sunday however, as alberto moves into the eastern gulf of mexico. This will bring a prolonged period of dangerous winds and seas to the region. Gale force winds with gusts to tropical storm force will be likely over the offshore waters, with sustained winds of 20 to 25 knots near the coast. This will allow seas to build to 8 to 12 feet Saturday night through Monday. Additionally, bands of Thunderstorms with strong wind gusts and waterspouts will be possible from late tomorrow night through early Monday. Conditions should gradually improve late Monday into Tuesday as alberto moves inland with winds and seas subsiding. Thereafter, south/southeast wind flow looks to persist mid to late week at 15 knots or less.

Evening update
After a day of widespread showers and storms, activity has
settled down quite a bit. Expect lingering light shower
activity to diminish by midnight with partly to mostly
cloudy skies thereafter. Light east southeast winds will
persist with high pressure extending across northern
florida.

We continue to monitor alberto, which remains just east of
the yucatan coastline. Tropical storm watches have now been
issued for portions of the northern gulf coast, but the
center of alberto is forecast to remain well west of tampa
bay. Still, impacts will be felt with repeat rounds of
showers and storms. We will have a nice respite tonight, but
tomorrow and tomorrow night will feature much greater
coverage of convection as alberto beings lifting northward
into the eastern gulf of mexico.

As for the forecast, only a few modest changes were made to
the existing wind forecast to capture a slight enhancement
of winds over the southern waters toward morning. Small
craft conditions may develop, especially over the offshore
waters late tomorrow afternoon into the evening, but will
wait for the overnight shift to review the latest on alberto
before issuing any marine hazard products.

Aviation (00z tafs)
Vfr conditions to prevail much of the overnight period.

Showers and storms will build back into the region from
north to south beginning around 10z to 12z and affecting all
terminals. Ifr to lifr ceilings and visibilities could
accompany this activity.

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.
