Discussion
Current-overnight... The 23z kxmr sounding came in with a pwat of
1.79 inches. Plentiful moisture, instability, and mid-level energy
aloft enough to keep convective activity going thru this evening.

Occasional lightning, heavy downpours, and brief gusty winds remain
the main concerns with precip. Will likely keep a schc for showers
in the fcst overnight with chc mention near the east coast. This as
moisture, mid-level impulses, and an approaching weak surface trough
keep the small threat valid. Greatest coverage likely across the
gulf stream overnight. Overnight lows in the u60s to near 70f. Will
send an update to the zones later this evening to clean up first
period wording.

Tuesday... Previous... Surface trough thetae front will slide eastward
across central florida during the day. Expect another round of
diurnal showers and a few storms as low-mid level SW flow will favor
the eastern side of the peninsula for higher precip chances.

Greatest coverage will be south east in area of lingering deeper
moisture. Pops will range from 20-30 over the far north CWA to 60-70
across lake okeechobee and the treasure coast. Highs in the l80s.

Aviation Scattered convection with brief MVFR conds to continue
thru the evening. A small threat will remain overnight with deep
moisture, mid-level support, and approaching weak surface trough all
in play. Potential ifr CIGS developing near TAF sites overnight with
improvement to MVFR by around mid-morning. Trough will push across
ecfl on Tue with highest precip threat kmlb southward during the day
where moisture remains deepest. Wsw winds on Tue approaching 15 kts
at times.

Marine
Overnight-tue... Small craft exercise caution continues tonight for
offshore legs for seas building to 4-6 ft, though a subsiding trend
will continue late tonight into tue. Ssw SW winds tonight
approaching 15-19 kts at times offshore, especially near
showers storms, but will be on a decreasing trend late in the night.

A few storms overnight over the gulf stream could be on the strong
side with lightning, gusty winds, heavy downpours the main threats
here. Swrly winds on Tue generally 10-15 kts over the open atlc.

Seas on Tue 4-5 ft offshore and 3-4 elsewhere.

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.
