Discussion
Light isolated showers have been favoring the coastal waters
surrounding the upper keys late this afternoon and this evening.

Ir satellite images show the only clouds in or near the service
area are associated with these few showers and another patch of
showers just beyond our southwestern atlantic marine zones.

Temperatures along the island chain are in the middle 70s at this
hour with a moderating east to southeast breeze.

The local evening sounding shows winds remain east to southeast
through the low and mid levels, but speeds have diminished through
much of that depth from twelve hours ago. That downward trend is
even more evident on the sounding from our neighbors in the
southern mainland, so we expect that to continue nearby overnight
and moreso through Sunday morning as high pressure settles
southward. Again this evening there is enough moisture and low
level confluence to support at least a few showers. Overall, the
afternoon zone forecast has the expected conditions covered well.

The only potential need to update the zones would be to remove the
downward trend to the winds. Will make that decision on the
observations that come in at the top of the hour.

Marine
On the upcoming coastal waters forecast, the initial wind speeds
will be cut by a few knots from the afternoon issuance... Basically
removing the downward trend advertised then. Expect only a few
showers anywhere in the marine service area through the overnight
period.

Aviation
Vfr conditions will continue at the key west and marathon
terminals overnight. There is a slight chance of a quickly
passing shower which my result in very brief MVFR conditions at
either terminal. Surface winds will be from the east southeast
near 10 knots.

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.
