Update
Expanding the wind advisory into inland portions of nassau and
duval counties with this update, based on observations and
projected winds.

This surge in winds is due to a strong pressure gradient across
the region, in response to the area being between low pressure to
the south and high pressure to the north, with a trough near the
atlantic coast. As this trough moves toward the coast, a few
showers south of st augustine will be possible this afternoon.

Highs will range from the middle 60s along the coast, to the
middle 70s well inland.

Aviation
Gusty conditions will be expected today, especially near the
coast. In addition stratus will advect in off the atlantic today,
producing restrictions.

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.
