Discussion
Currently
Some showers are moving southeast across the keys area at this
hour. Winds are out of the northeast at 5 to 10 knots at the
island terminals, and near 10 knots at the marine reporting
stations.

Forecast
A weak pressure pattern will continue for the weekend due to maria
east of the bahamas, and high pressure to the north. Cyclonic flow
aloft with light easterly flow in the low levels, and ample
moisture would suggest at least a high chance of showers. The only
thing lacking is a good lifting mechanism. Any lifting that
occurs will be in the guise of lingering, or propagating outflow
boundaries off activity from the florida peninsula or cuba. No
changes will be required in this forecast cycle.

Marine
No advisory or cautionary statements are expected through
Thursday. Outside of scattered showers and isolated thunderstorms,
breezes will remain light to gentle and mainly out of the
northeast.

Aviation
Today,VFR conditions will prevail at both the eyw and mth int'l
terminals. After 16z, scattered showers and isolated thunderstorms
may impact either both terminals with short lived MVFR ifr cigs
and vis. Winds will be light and north to northeast from the surface
to about fl080-100.

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.
