Synopsis Surface high pressure across the central atlantic
will drift eastward while another strong surface high enters the
western atlantic on Friday. A cold front is forecast to move north
of the region during the upcoming weekend. This will result in
breezy conditions across the region. Upper ridge is expected to
hold over the region through early in the weekend.

Short term Today through Friday...

trade wind moisture transport will continue across the region with
occasional cloudiness and brief showers expected to continue into
early morning hours. Rainfall will be mostly light to moderate but
isolated areas along the east coastal sections of pr may experience
quick bursts of locally heavy rains in isolated spots. Increasing
shallow moisture advection today through Thursday will support
isolated to scattered showers development mainly across the interior
and west sections of pr during the afternoon hours. The shower
activity however is expected to quickly stream westwards in the
prevailing moderate trade winds. This will result in minimal
rainfall accumulations. On Friday, lesser moisture transport as
upper ridge slightly erodes supporting somewhat drier conditions
with mostly fair weather and breezy conditions, except for locally
induced afternoon showers over the west and southwest sections of
pr, under a prevailing northeast wind flow.

Long term Saturday through Thursday of next week...

the upper level ridge is expected to erode rapidly Saturday
through Sunday, as a polar trough amplify and spread eastward
across the west and central atlantic. This will provide better
support for shower activity across the u.S. Virgin islands,
vieques, culebra as well as across the eastern half of puerto
rico during the nights and mornings hours followed by more afternoon
convection across portions of the interior and western sections
of puerto rico.

A strong surface high pressure is forecast to move across the
west and central atlantic behind the cold front Saturday and
Sunday. This feature will remain north of the area, producing
breezy east to east-northeast wind flow across the region during
the weekend and until early next week. As a result, cooler
temperatures but more frequent passing shower activity is expected
due to the increasing northeast winds and frontal boundary
moisture which will sinks southwards and be transported across the
region from time to time. Gradually improving weather conditions
are forecast Tuesday through Wednesday with a return of more
typical passing trade wind showers and isolated to scattered
afternoon showers mainly over the west and interior sections of
puerto rico.

Marine Small craft are urged to exercise caution as seas will
be up to 6 feet. There is a moderate risk of rip currents across
most of the local beaches. Local seas will remain choppy and up
to 6 feet for the next couple of days. A north to northeasterly
swell will invade the local waters late on Friday, which will
likely cause a significant increase in wave heights and hazardous
seas through the weekend. Stay tuned.

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.
