Marine Weather and Tides
Florida City, 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.

Aviation
An area of moisture continues to reside over south florida,
bringing scattered showers to much of the area. Most of the
showers are light in nature and thunderstorm activity has been
minimal at best. Shra should come to an end this evening, and pick
up again tomorrow, although coverage may be sparse once again.

Kept vcsh this afternoon, to cover the pop up shra that does occur
along the coast, although no impact to flight conditions is
forecast.

update...

this mornings update just tweaked pops a little, with no
significant change. Just includes new hi-res models. Showers are
forecast to be possible all day across the area. A few
thunderstorms are possible as well, but kept at a slight chance,
except for a chance in the western lake region late this
afternoon.

Prev discussion... Issued 340 am edt Tue may 22 2018
discussion...

scattered showers have continued overnight across portions of the
atlantic waters as well as extreme southern areas of the florida
peninsula. These showers are still associated with the plume of
tropical moisture that has been affecting the region over the past
several days. This pattern is expected to continue during the day
on Tuesday. The highest rain chances will be focused across the
western and northern areas. The chance of showers and a slight
chance of thunderstorms will continue during the day on Wednesday
as plenty of moisture remains in place. Once again, the latest
models show the highest rain chances to be located over the
interior and western areas.

Later in the week into the weekend, both of the GFS and the ecmwf
continue to show different solutions regarding the handling of a
disturbance expected to lift out of the western caribbean into the
central or eastern gulf. That region will be in an area of upper
diffluence associated with the left exit region of an upper jet
over the western gulf, and potentially the right entrance region
of an upper jet over the southeast states, encouraging surface
pressures to fall.

It is still too early to say whether any low development will
move more north toward the northern gulf coast or more toward the
western fl coast panhandle. Either way, it appears south fl will
be on the east side of this system bringing another surge of
moisture northward over the state. Given the saturated conditions,
we will need to watch for the potential for heavy rain again this
weekend.

Marine...

an area of low pressure in the gulf of mexico will continue to
produce a pressure gradient with an area of high pressure located
in the western atlantic. This will continue to produce a east to
southeasterly wind flow across the gulf and atlantic waters
between 15 and 20 knots through the middle of the week. Winds will
start to diminish slightly on Tuesday night into Wednesday as the
ridge in the atlantic tries to move slightly westward. Scattered
to numerous showers and isolated thunderstorms will affect both of
the atlantic and gulf waters through the week. Winds and waves
could be higher in and around any shower or thunderstorm.

Beach forecast...

high risk of rip currents continues at the atlantic beaches
through Tuesday evening due to moderately strong onshore winds. An
elevated risk may continue at least into Wednesday.

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.
