Vfr conditions will hold through the next 24 hours under
light northeast winds, turning to northwest in the
afternoon.

Prev discussion issued 821 pm est Sun dec 10 2017
evening update...

a cold and clear night is expected as high pressure settles
in across the florida peninsula. With light to calm winds
and clear skies, conditions will be optimal for radiational
cooling, and expect lows to bottom out in the upper 20s to
lower 30s in some areas north of i-4. Mid to upper 30s will
be widespread and frost can be expected most anywhere away
from the coast. As such, any sensitive plants should
probably be brought indoors just to be safe, and certainly
where freeze warnings are currently in effect.

No major changes were needed to the existing forecast.

Marine... High pressure will continue to settle in over the
waters, allowing winds and seas to subside overnight with
favorable boating conditions expected through early Tuesday.

Another cold front will bring cautionary to advisory
conditions late Tuesday into Wednesday with improving marine
conditions for the end of the week.

Fire weather...

very dry air has filled in behind a strong cold front. This
will bring periods of critically low humidities both Monday
and Wednesday this week as another cold front moves
through. Despite this, erc values will remain high and winds
relatively light. This will prevent any need for red flag
watches or warnings. Gradual moistening is expected for the
latter half of the week, with rising humidities.

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.
