Synopsis A band of moisture moving across the region today will
bring scattered showers from time to time. Fair weather conditions
will likely prevail most of the weekend except on Sunday afternoon
when another band of low level moisture approaches from the east.

Models continue to suggest a wetter pattern the second part of
next week as trough pattern establishes over the western
atlantic.

Short term Today through Sunday...

a broad inverted surface trough across the central and eastern
caribbean and a high pressure ridge extending southwest from across
the northeast atlantic, will maintain a light east southeast wind
flow across the forecast area today through early Saturday. Winds
are forecast to become more easterly by Sunday and Monday as another
surface high pressure ridge will enter the west atlantic and
reinforce the aforementioned northeast atlantic ridge.

Increasing low level moisture and cloud cover today will support a
better chance for early morning showers across the islands and
coastal waters, as an easterly perturbation will continue to cross
the region. During the afternoon, expect the shower activity to
spread westward and should then be focused across parts of central
and northwest puerto rico under present low level steering flow.

Periods of moderate to locally heavy rains will be possible over
these areas. Meanwhile, shower activity and cloudiness across the
remainder of the islands including the u.S. Virgin islands should
gradual diminish during the afternoon leaving partly cloudy to
mostly sunny skies with limited rainfall accumulations expected.

On Saturday, expect the local winds to gradually become more
easterly throughout the day, as another surface high pressure ridge
will enter and spread across the west atlantic. This will reinforce
the northeast atlantic high during the rest of the weekend,
resulting in the tightening of the local pressure gradient and
increasing easterly trade winds. A lull in trade wind moisture
transport is still forecast for Saturday, however lingering pockets
of moisture will be sufficient to support locally induced afternoon
showers which should again be focused over parts of the interior and
west sections of puerto rico. Mostly fair weather skies can be
expected for the remainder of the islands on Saturday as a mid to
upper level ridge will remain in place over the northern leewards
and therefore limit any convective development.

On Sunday another surge of trade wind moisture is forecast to bring
an increase morning shower activity and this again will increase the
chance of afternoon shower development across the islands especially
over the central interior and west sections of puerto rico. The u.S.

Virgin islands may also experience brief periods of passing showers
over the weekend but widespread rainfall is not anticipated at this
time.

Long term Monday through Friday...

a short-wave trough over the eastern caribbean will allow
moisture to pool across the local region early next week. With a
weak cap and higher moisture content, showers will likely to
develop across portions of the islands especially over the west
interior and northwest puerto rico each afternoon. Conditions
will become more favorable for showers on Wednesday as a long
wave trough establishes north of the area. The trough will be
strong enough to push a frontal boundary closer to the local
islands. With deeper moisture pooling across the islands and good
upper level dynamics, the environmental conditions will favor the
development of organized convection. If this unsettled pattern
materializes, the local islands may see some beneficial rainfall
later in the week.

Marine Moderate winds will persist through Sunday, increasing
somewhat early next week as high pressure moves across the western
atlantic. A small northeast swell will reach the local islands
between Sunday and Monday, as a result seas will build across the
local atlantic waters and caribbean passages. Overall, seas will
continue at 3-5 feet increasing to 4-6 feet on Monday with the
swell action. Moderate rip currents will continue along the north
coast of the local islands for several days.

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.
