Synopsis for puerto rico and the uS. Virgin islands waters... As a high pressure builds into the western atlantic, the winds will increase across the local area this afternoon through Wednesday night, causing the local marine conditions to be hazardous. A cold front to the northwest of the local area is not expected to reach the local waters, but a pre-frontal trough will bring scattered showers to the local waters. Winds will diminish starting on Thursday.

Synopsis Frontal boundary across the western atlantic is
expected to move south and east over the next few days but should
remain north of the local islands. Surface high pressure will move
east from the western atlantic, causing an increase in the local
winds this afternoon and Wednesday. Upper level ridge will prevail
for the next several days.

Short term Today through Thursday...

although an approaching frontal boundary is expected to remain to
the northwest of the forecast area, it will promote a shifts in the
winds to the northeast today through Thursday. This wind flow is
expected to strengthen up to 25 mph late tonight into Wednesday as
the frontal boundary approaches the region. On Thursday, winds will
shift once again from the east as the associates surface high
pressure, now moving over the western atlantic, continues to migrate
eastward. Embedded within this wind flow, patches of low-level
moisture will continue to bring cloud clusters and passing showers
to windward areas of the local islands, increasing in frequency as
the wind flow increases. This activity will be followed by showers
developing over portions of the interior and western puerto rico, as
well as downwind from the local islands and mountainous areas of
puerto rico each afternoon. Afternoon showers will favor the
southwestern quadrant of the island today and Wednesday, with a
shift to the northwestern quadrant on Thursday. However, due to the
presence of a mid to upper level high pressure meandering over the
region and an expected rapid motion of any developing shower,
significant rainfall accumulations are not expected.

Long term Friday through Wednesday...

the long term forecast does not look particularly active as drier
than normal air mass is expected with fragments of higher moisture
bringing brief showers. The winds are expected to be generally
from the east at around 10 to 15 mph, occasionally to 20 mph in
gusts across the coastal areas. Either a ridge or zonal flow is
expected in the upper levels in the long term, and the mid levels
should be fairly dry. All of this will promote a fairly stable
atmosphere for the most part, limiting the intensity and coverage
of the afternoon convection, while brief showers are expected
across eastern pr and the usvi in the early morning and overnight
hours. The only feature that could bring higher cloudiness and
somewhat persistent rain the expected fragmented front north of
the area that could bring higher moisture and cloudiness on
Friday.

Aviation MostlyVFR conditions expected across all terminals. A
cloud cluster moving over tist and tisx will result in bkn
conditions at fl050-070 and vcsh through 22 14z. Afternoon showers
will result in vcsh at tsju and tjmz between 22 14 and 22 22z.

Surface winds will be light and variable through 22 14z, then
turning from the northeast and increasing up to 18 knots with higher
gusts. The strongest winds will affect tjbq, tist and tisx after
22 18z.

Marine Seas will gradually deteriorate today and will continue
hazardous for most of this week as a northerly swell invades the
local waters and the local winds increase. Small craft advisories
will go into effect starting late tonight or early Wednesday
morning. Moderate risk of rip currents today, but high risk of rip
currents expected starting this evening.

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.
