Synopsis A relatively dry and stable weather pattern will prevail
across the forecast area as an upper level ridge will continue as
the main weather feature across the region until at least Monday.

An upper trough northeast of the region is expected to sink
southward over the lesser antilles by midweek increasing the
moisture across the local islands.

Short term A fair and stable weather pattern is forecast to
prevail across the region the next couple of days. There is still
a chance for locally and diurnally induced afternoon showers each
day, mainly over the western portions of puerto rico.

Long term An upper level low trough northeast of the region is expected to
sink southward toward the leeward antilles on Tuesday and Wednesday.This
feature will result in a gradual increase in moisture across the region
by midweek. However, at this moment not significant or widespread precipitation
is expected. A tropical wave is expected to reach the region Friday
generating a better chance of showers and thunderstorms through next
weekend.

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.
