Update
The west coast sea breeze moved well inland this afternoon and
eventually collided with the east coast boundary right across the
center part of the state. Broken shower and thunderstorm activity is
ongoing from polk county stretching south into lee county, but
activity has been gradually weakening and will continue to do so over
the next couple of hours, with the rest of the night remaining dry.

The ongoing forecast is in good shape, with no updates needed this
evening.

Aviation
Still a chance for some brief shower or thunderstorm activity mainly
at kfmy and krsw, but this threat will be diminishing over the next
couple of hours.VFR conditions can generally be expected otherwise.

Winds will become southerly overnight and into the morning hours, and
then will switch to southwest in the afternoon, with speeds
increasing and gusts of 20-25 knots likely.

Marine

days, with winds turning to the southwest. Winds will increase near

pressure then moving into the area for the end of the week. Numerous
to widespread showers and thunderstorms, with some strong storms
possible, are anticipated across the waters Tuesday night into

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.
