Update
As of 935 am edt... Only major update to the ongoing forecast was
to cancel the fire weather watch for inland collier county, and
replace with a special weather statement as confidence is not high
enough that the winds and relative humidity will meet critical
thresholds over a wide enough area. There will still be an
elevated fire weather risk for this area, and a red flag warning
continues as well for glades and hendry counties until 8pm, where
critical thresholds are more likely to be met. Rest of forecast
is on track with only minor updates to account for the latest
trends in observations. Dry weather and gradually decreasing cloud
cover will prevail today, with high temperatures generally in the
lower 80s.

vfr flying conditions will prevail through the TAF period ending
12z Wednesday. Outside of some few/sct clouds around 4-5 kft this
morning, minimal cloud cover is expected through the period. Some
patchy interior fog will be possible late in the period at ktmb
and kopf. For the east coast sites, light and variable winds early
this morning will become westerly around 8-13 knots, trending to
light and variable after 00z. Winds will be westerly at kapf
around 8-15 knots through 00z, before decreasing to around 5
knots.

Red flag warning for glades & hendry counties
Fire weather watch for inland collier county
Discussion...

south florida is now in the drier air behind a frontal boundary
that has cleared into the caribbean and bahamas. The parent low
pressure system remains over the southeast united states and will
north along the eastern seaboard of the united states over the
coming days. Today will be a dry and somewhat cooler day across
south florida. As the week continues, the airmass over the region
will moderate a bit as the next frontal system pushes across the
country.

This next frontal system will push towards florida by week's end.

This system will be capable of creating a tightening gradient that
may cause some gusty southeasterly flow across the area, but
widespread rainfall does not appear to be in the cards for south
florida this weekend. Instead, temperatures will increase to a
summer-like lower 90s across much of the southern peninsula late
week heading into the weekend.

Deep layered atlantic high pressure will hang over the region
into the weekend as the next frontal system emerges over the
central united states. This front will push into our region late
in the extended forecast period but could potentially pack enough
punch to reach as far south as south florida with some chances of
showers and thunderstorms to kick off early next week. Both the
00z GFS and 00z ECMWF have similar solutions which increases
confidence a tad, but trends will have to continue to be similar
as we get closer in time to definitively say that this could be
our next chance for wetting rain across the region.

Marine...

high pressure will build across the region for the coming days,
allowing a lighter flow over the waters. As the wind lightens,
seas will diminish today. Overall, conditions over the next
several days should remain rain-free.

Fire weather...

drier air filtering over the region today creates a fire weather
concern over southwest florida for this afternoon. A red flag
warning is already in effect for glades & hendry counties due to
expected long durations late this morning through the afternoon of
relative humidity values below 40 percent. A special weather
statement is in effect for inland collier county due to the
winds and relative humidity expected to be just around critical
levels.

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.
