GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 1029 Am Edt Sun Aug 25 2019
Synopsis.. North to northeast winds this afternoon with relatively low rain chances over the waters. Through midweek, west to southwest flow setup will allow for a better chance of showers and storms early in the morning across the eastern gulf waters which will then move inland through the day. No headlines are expected at this time as winds and seas will remain below thresholds... By later in the work week into the weekend, a broad trough of low pressure in the gulf will increase rain chances across the eastern gulf waters.

Similar to yesterday, MVFR with brief periods of ifr CIGS are
occurring this morning across pgd fmy rsw and conditions should
improve by 14-15 utc. Have elected to go ahead and remove mention
of vcts at tpa pie srq as convective coverage is expected to be
low through the afternoon. Otherwise, winds will be out of the
north to northeast before shifting onshore near coastal terminals
by mid afternoon.

discussion...

the weak area of low pressure that has been over south florida for
the last few days will begin to move further north today into the
western atlantic. Chances for tropical development remain high with
this system although no direct impacts are expected to our state
as it will continue to parallel the us east coast over the next
few days. Closer to home, drier air remains in place today which
will help suppress shower and storm coverage once again today.

Pops will be in the 30-50 percent range for much of the area,
highest inland. The departing system will create southwest flow on
Monday and with moisture increasing over the area (pws climbing
above 2 inches) expect morning showers thunderstorms to develop
before gradually migrating inland throughout the day. This SW flow
regime will continue through Thursday as the bermuda-azores high
begins to build back in on Thursday at the surface. The
anticyclonic (clockwise) movement of air around the feature at the
surface will cause winds to become more ese by late in the work
weak. This ese flow will continue to keep the pattern wet with
diurnal storms, particularly in southwest florida as a deep plume
of moisture from the caribbean will be advected over the peninsula
into next weekend. Temperatures will run near to above normal
through the period.

Marine...

fairly benign weather can be expected across the coastal waters
through the period. Winds will remain north-northeast 10 knots or
less for the remainder of the weekend although a seabreeze will
shift winds onshore this afternoon. Then on Monday, winds will
shift to the west-southwest and continuing 10 knots or less
through the middle of next week. Winds will increase to around 10
to 15 knots with increasing rain storm chances through Thursday
next week. So outside of any storms, winds should remain below 15
knots and seas 2 feet or less.

Fire weather...

sufficient low level moisture will keep relative humidity values
above critical levels through the week with no red flag conditions
expected. No significant fog is expected through the period.

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.
