GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 348 Am Edt Tue Sep 26 2017
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.

short term (today and Wednesday)...

a high amplitude trough continues to extend from the desert
southwest into the northern plains, generating heavy
rainfall across portions of the high and central great
plains region. Meanwhile, weak upper ridging resides from
the gulf of mexico into the western atlantic ocean, with
two exceptions. One being a weak upper cutoff low still
centered over the northern gulf coast, and the other being
hurricane maria, which continues to lift northward off the
southeast u.S. Coast. As the low pressure center associated
with maria continues to lift away from the region, we will
remain poised between surface high pressure to the
northwest, and departing low pressure to the northeast. The
result will be a dry spell.

For today and Wednesday, drier air will slowly filter into
the region with light northerly winds. With very weak
gradient flow, the seabreezes will be quite pronounced each
afternoon, with breezy onshore winds near the coast.

Seabreezes will converge over interior parts of the
peninsula mid to late afternoon, but with lacking moisture,
only isolated showers and storms are expected. At this time,
the highest rain chances, which will generally be 20 to 30
percent, will remain over southern florida, where slightly
greater moisture will reside. Otherwise, expect dry
conditions with highs reaching the lower 90s each afternoon
and upper 80s along the coast. As drier air fills in,
morning lows may be slightly cooler than on recent mornings,
with upper 60s to lower 70s north, and low to mid 70s
south.

Mid long term (Wednesday night through next Tuesday)...

at the start of the mid long term forecast period, models
continue to show the presence of an upper low around the
florida peninsula. At the surface, a strong ridge to the
north will keep a northeast flow regime in place into next
week. Drier air that was in place over the area earlier in
the week will begin to give way to increasing moisture on
Thursday and this trend will continue into the weekend. Sct
rain chances will be mainly limited to SW florida on
Thursday but by Friday much of the CWA will return to pops
in the 30-50 percent range and this will continue into next
week. Temperatures will top out near 90 Thursday and Friday
but mostly upper 80s expected into the weekend with
increased cloud cover. Overnight lows will continue in the
low to mid 70s.

Marine...

a weak pressure gradient will persist over the waters much
of the coming week, resulting in light north to northwest
winds. Winds will increase and shift onshore near the coast
each afternoon due to the seabreeze. A dry forecast is
expected until late week into the weekend, when rain chances
will gradually increase. Easterly flow pattern will resume
by the weekend as high pressure builds in to the north.

Fire weather...

a brief period of lower afternoon humidities of 40 to 50
percent will exist through Thursday, as slightly drier air
filters into the region due to light northerly winds.

Gradual moistening will occur from Friday into the weekend
with increasing rain chances. Given humidities will remain
well above critical levels, no fire weather concerns are
expected.

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.
