Update
Weather conditions across west central and southwest florida are
starting out on the beautiful side this morning. Satellite imagery
and surface observations are showing mostly sunny skies across the
region. The 12z morning sounding is showing a relatively dry air
mass over the region with a pw of only 1.30 inches. Latest model
guidance is showing a mostly rain-free day in store for us today
with only a chance of an isolated shower south of the i-4 corridor
later this afternoon. Under these sunny skies, temps will warm up to
slightly above average with low 90's expected region wide. No
changes needed for the forecast at this time.

Aviation
20 12z tafs.VFR conditions will prevail at all terminals through
the next 24 hours. Very few clouds this morning, then slightly
increasing to a sct CU deck this afternoon. Northern terminals will
stay dry while pgd fmy rsw may see a stray shower this afternoon, so
will cover that with vcsh after 18z. Winds will remain light less
than 10 knots. No other aviation impacts expected.

Marine
High pressure with a relaxed gradient will dominate the waters
through the end of the week with benign conditions expected. During
the weekend hurricane maria moving across the southern waters of the
atlantic will tighten the gradient with an increase in wind speeds.

Mariners should monitor the progress of hurricane maria... Detailed
information on maria may be found on advisories from the national
hurricane center.

Hydrology
Residual river run-off from the heavy rains associated with
hurricane irma last week continues to cause flooding issues for many
rivers across west central and southwest florida. Most rivers in the
area have seen their peak flooding and are on a gradual receding
trend. However... The withlacoochee river at trilby and croom will
continue to slowly rise... Cresting either today or tomorrow. The
river levels will then generally remain steady through the remainder
of the week... Which will prolong the worst flooding this area has
seen in over 50 years.

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.
