Marine Weather and Tides
Indian Rocks Beach, 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
A deep layered southeast to southerly wind flow between high
pressure over the atlantic and a mid and upper level trough
over the east-central gulf of mexico will continue to pull
deep tropical moisture (pw's in the 1.8 to 1.9 inch range)
over the entire forecast area the remainder of tonight with
isolated to scattered showers possible at any time under
cloudy skies. It will be a mild night with low temperatures
bottoming out around 70. The current forecast is in good
shape with no evening update required at this time.

Additional showers and isolated storms along with some
locally heavy rain in some locations will be possible over
the forecast area on Monday as deep layered moisture remains
in place over the region.

Aviation
Mainly MVFR CIGS with brief ifr CIGS will persist at all
area terminals tonight, with intermittentVFR. Isolated to
scattered showers can be expected at just about any time
and have handled with vcsh for now, with MVFR ifr vsbys
possible with any shra. On Monday MVFR CIGS will continue
with lower ifr CIGS vsbys likely after 15z as shra and
isolated tsra coverage again increases across the region and
have depicted prevailing shra after 18z with some tsra in
the vicinity. East-southeast winds in the 6 to 8 knot range
will prevail with higher gusts possible in the vicinity of
tsra.

Marine
Southeast to south winds around 10 knots with seas of 2 feet
or less will continue over the gulf waters the remainder of
tonight with deep layered moisture supporting scattered
showers and isolated storms. Ongoing forecast is on track
with no changes expected in the next update around 9 pm.

Hydrology
Heavy rainfall over the last week as well as today has
caused area rivers to rise with the manatee river near
myakka head, the alafia river at lithia, and horse creek
near arcadia now in minor flooding. With additional heavy
rainfall possible over the next few days other area rivers
and streams around the region may approach flood stage with
additional river flood warnings a possibility. All residents
living along rivers or faster flowing streams should remain
alert for any rapid rises in water levels and be ready to
move to higher ground if flooding is observed.

Tbw watches warnings advisories
Fl... None.

Gulf waters... None.

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.
