Discussion
Currently - an atlantic surface high extends a ridge across
florida into the gulf of mexico. This is generating gentle to
moderate east breezes across the keys and surrounding waters.

Meanwhile, nearly zonal flow is in place aloft and ridging in the
mid levels. This mornings sounding indicated quite a lot of dry
air aloft, but little in the way of inhibition. Isolated showers
have persisted, mostly on the surrounding nearshore waters, with
tops of 15 to 20kft. A few of these showers have crossed a number
of island locations, usually dropping little more than a trace.

Relatively warm moist flow is in place at the surface and
temperatures are climbing towards 80 with dew point temperatures
in the mid 60s.

Short term update - gentle to moderate east breezes will continue
across the florida keys this afternoon as ridging remain to our
north. Weak showers near the keys are expected to continue
weakening. No significant forcing and dry air aloft should keep
afternoon shower activity to a minimum. In addition, easterly
lower level flow should keep any island cloud line shower
development off the archipelago. Expect temps to top out in the
lower 80s.

Marine
Gentle to moderate east breezes will continue on keys waters due
to a ridge across the florida peninsula. Essentially no changes
made in the morning marine update.

Aviation
Rest of today,VFR conditions will prevail today at both the eyw and
mth int'l island terminals with winds from 070-090 AOA 9-11 knots.

Just a few clouds will be found AOA fl020-025 & fl040-050
respectively.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
