Synopsis..As hurricane maria continues to pull away from the region over the western atlantic ocean and high pressure remains to our north and west, we will maintain weak gradient flow with light and variable to light north/northwest winds much of the week. Dry conditions are expected through at least mid week with a gradual return of moisture and increasing rain chances Friday into the weekend. High pressure also looks to build in north of the waters over the weekend with a sustained easterly flow pattern setting up.

943 am edt Tue sep 26 2017

Update
Weak high pressure to the northwest and hurricane maria
moving slowly north over the atlantic east of the mid
atlantic coast will allow some drier mid level air to
filter into the forecast area the remainder of the day.

This drier air should keep overall rain chances below
normal, however adequate low level moisture combined with
daytime heating should result in isolated to widely
scattered shower storm development over inland locations
along the sea breeze during the afternoon and across
southern most locations where better moisture will reside
while mainly dry conditions are expected from the bay area
north into the nature coast. Afternoon temperatures will
climb toward 90 along the coast prior to the onset of the
sea breeze, with lower 90s expected over inland areas.

High-res model output and ongoing forecast concurs with
this so a morning update will not be required at this time.

Aviation
Lifr ifr CIGS vsbys at kpgd from low clouds and some fog
will linger through 14z, otherwiseVFR is expected at all
terminal sites during the next 24 hours. A few shra tsra
will be possible at kfmy and krsw after 21z and have handled
with vcts for now. Light and variable winds will become
west at 7 to 9 knots after 16z as the sea breeze develops.

Light and variable winds will return to all sites after 02z
tonight.

Marine
Light winds and slight seas are being observed over the gulf
waters early this morning, and little change to current
conditions expected through the afternoon with a weak
pressure pattern supporting an onshore sea breeze
component around 10 knots developing along the coast during
the afternoon. Ongoing forecast is on track with no changes
expected in the next forecast issuance around 10 am.

Hydrology
While moderate to major flooding continues on the
withlacoochee river in pasco and hernando counties, the
river is slowly receding. As the water routes farther
downstream, minor flooding is still forecasted to begin
over the next couple of days in northern citrus county. The
withlacoochee river has not flooded in some of these
locations within the last 10+ years. Elsewhere, levels
continue to recede along most of west central florida's
rivers. With no widespread rainfall expected over the next
several days, additional flooding is not expected to occur.

Most of the flooding that occurred from hurricane irma
resulted in the worst flooding many places have seen in the
last 50-70 years. For example, the official crest on the
peace river at arcadia of 19.20 feet was the 3rd highest on
record and the worst flooding since 1933.

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.
