Discussion
Currently - high pressure over the southeastern united states and
gulf of mexico is maintaining gentle to moderate northeast breezes
across the florida keys. Meanwhile, a weak lower level
perturbation, responsible for lower level lift, is producing a
rather expansive field of stratus stratocumulus across the area.

This activity is trapped under a healthy inversion based around
780 mb. Scattered patches of light rain are present primarily over
the florida straits adjacent to the marquesas and lower keys and
surrounding waters. Temperatures are in the mid 70s across the
area with dew point temperatures in the mid 60s.

Short term update - gentle to moderate northeast winds will
prevail across the keys through the overnight hours. The lower
level perturbation will work its way westward. At the same time
the inversion is expected to erode overnight. As a result, patchy
rain should become more discrete isolated showers and the cloud
field should break up, becoming partly cloudy. This may be quite
late in the overnight hours. Overnight lows will only fall a
degree or two further.

Marine
Moderate northeast breezes will prevail across keys waters due to
a high pressure system over the southeastern united states and the
gulf of mexico. Cautions are in place for hawk channel, florida
straits, and the nearshore gulf zones. Only minor changes made in
the evening marine update.

Aviation
Vfr MVFR conditions expected through the overnight period at
island terminals. This is due to a blanket of stratus and
stratocumulus that has had varying bases between roughly 2500 and
4000 ft. Expect bases to trend upwards over all and begin breaking
up.

Key watches warnings advisories
Fl... None.

Gm... None.

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.
