Marine Weather and Tides
St. Petersburg, 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.

Morning update
A few morning showers and storms have diminished as the
seabreeze is getting underway, leading to subsidence over
the waters. Expect showers and thunderstorms will begin to
develop along near the coast through noon. This activity
will likely spread inland, colliding with the east coast
seabreeze by mid afternoon, where storms will be more
widespread. Outflows will gradually work back to the west,
with thunderstorms shifting back to the west and out into
the gulf of mexico this evening. In all, it's looking to be
a much more active thunderstorm day than we have seen in
quite some time. Beneficial rains are expected across a good
part of the suncoast, but along with the rain will come the
threat of gusty winds and frequent lightning. Make sure you
head indoors as soon as you hear thunder or see lightning
in the distance!
no substantial changes were made to the existing forecast.

Aviation (12z tafs)
Vfr conditions will continue through around 16z to 18z when
thunderstorms will develop near most terminals. Will
maintain vcts this issuance, but will likely include tempos
in next TAF set as confidence is fairly high in widespread
coverage of shra tsra 20z to 00z timeframe. Ifr to lifr
ceilings visibilities possible with any storm along with
gusty winds.

Marine
High pressure will remain over the waters through the
coming week with light winds and seas. The only exception
will be with any marine storms which could locally enhance
winds and seas. This would be most probable from the evening
hours through the overnight and into the early morning each
day.

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.
