Synopsis Strong surface high pressure will continue across the
western atlantic through early next week. Fresh to strong east to
northeast trades will persist through Thursday, decreasing
by the end of the week.

Short term Tonight through Friday... Cloudiness with showers
affected the local islands today. This was the result of an old
frontal boundary which is bringing periods of cloudiness with
showers at times. This weather pattern is expected to continue
through tonight, before a drier air mass encompass the region from
the north. For Thursday, dry weather conditions are expected with
less shower activity. Next round of cloudiness and showers is
expected by Friday.

Long term... Saturday through Thursday... (no changes from previous
discussion).

High pressure north of the region will hold through Tuesday
maintaining a moderate to fresh east to northeast trade wind flow
across the area. Trade wind showers will continue to move and
increase in frequency during the weekend across the region.

Meanwhile, an upper level trough and jet maxima pattern over the
region will aid in the development of more showers and a wetter
pattern by next week. Afternoon shower development is expected
along the mountain ranges of pr through the long term period.

Urban and small stream flooding in isolated areas will be
possible with the heaviest showers on Tuesday and Wednesday.

Aviation Vfr conds are expected to prevail through the forecast
cycle with brief -shra shra at the leeward and usvi terminals as
well as jsj jbq. Ene winds 15-25 knots with higher gusts, becoming

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.
