showers and thunderstorms that have developed across the region
this afternoon will begin to diminish as the the evening
progresses. High pressure currently located over the gulf of
mexico will begin to weaken on Friday as a trough of low pressure
digs into the southeastern portion of the country. This will
increase the shower and thunderstorm chances across south florida
on Friday and Saturday. At the same time, hurricane maria will
move in a more northerly direction. We do not expect any direct
impacts from maria as it will pass off to the east.

As the trough begins to lift out of the region later this weekend
into early next week, drier air will move into the region as the
winds become more northerly due to maria passing off to the east.

Therefore, the chances of shower and thunderstorm activity will
decrease by the beginning of next week across the region. Both of
the GFS and the ECMWF continue to show a northerly wind flow
through the middle to end of next week. This will help to keep the
drier weather in place across south florida with lower chances of
showers and thunderstorms.

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.
