Discussion
Currently - high pressure over the eastern united states, along
with hurricane maria, east of the northern bahamas, has resulted
in a light northeast flow across the florida keys. This evenings
sounding indicated near 2 inches pwat with no inhibition. The
combination of the weak flow and unstable conditions has allowed
isolated to scattered showers and thunderstorms to develop along
boundaries emanating off of south florida. More recently activity
has waned substantially.

Short term update - as hurricane maria continues to move north
northwestward and further away, the wind field across the keys
will become even weaker and turn more variable. The moist and
unstable conditions will prevail, and there will be a low chance
for showers and possibly a few thunderstorms. No changes required
for the local forecast.

Marine
Light northeast winds will slacken further and become variable in
direction as hurricane maria moves north northwestward and further
away from keys waters. Only a few minor adjustments may be made in
the evening marine update.

Aviation
Vfr conditions will prevail at the island terminals through the
overnight. A few showers and thunderstorms may affect the island
terminals with brief subVFR conditions. Winds will start out
tending weak northeasterly, becoming variable.

Key watches warnings advisories

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.
