Synopsis for puerto rico and the uS. Virgin islands waters... High pressure over the central atlantic will help to maintain gentle to moderate easterly winds across the regional waters. Brief isolated to scattered showers will continue to affect portions of the coastal waters during the overnight and early morning hours. Marine conditions are forecast to deteriorate as a northeasterly swell arrives and spreads across the atlantic waters Friday into Saturday.

Synopsis
Showers have begun to develop over interior puerto rico, as well
as downwind of EL yunque; further development is forecast for this
afternoon, especially over western and interior puerto rico, with
a risk of isolated thunderstorms. Elsewhere, mostly sunny skies
are likely to persist today. This generally stable weather pattern
will continue as conditions unfavorable for convection persist
aloft. Early next week, increased moisture and instability are
likely to push into the area, bringing increased shower and
thunderstorm activity. Late this week, a northeasterly swell is
forecast to bring hazardous marine conditions to some of our local
waters.

Short term Today through Friday...

the large ridge remains steadfastly in its place across the north
central atlantic, while a trough pushes in behind it stretching
southward across the west central atlantic. These systems are
maintaining a light to moderate generally east wind flow over the
region, shifting to more northeasterly Friday. Aloft, a mid- to
upper-level ridge is building into the area and will remain in
place over the next few days as well. Because of this, conditions
aloft will remain generally unfavorable for convective activity
during this same time period.

At lower levels, there will continue to be patches of moisture
brought through the region embedded in the trade winds. During the
overnight and morning hours, passing showers are likely to be seen
over the local waters, with some of the showers reaching coastal
areas in northern and eastern portions of the islands. The
rainfall amounts associated with these showers are not expected to
be significant. During the afternoons each day, local effects and
diurnal heating will combine with the low level moisture to aid in
the development of showers, with the potential for isolated
thunderstorms. The majority of these showers are likely to be in
western and interior puerto rico. Elsewhere, generally fair
conditions with mostly sunny skies are forecast, though an
isolated shower cannot be ruled out. Conditions will be
increasingly unfavorable for convection into the end of the work
week; decreasing shower and thunderstorm activity is expected.

Long term Saturday through Thursday... From prev discussion...

ridging aloft accompanied by a strong trade wind cap and drying
at mid-levels will maintain relatively stable weather conditions
on Saturday and Sunday. However, neither overnight and early
morning trade wind showers streaming over the regional waters into
windward areas nor limited afternoon convection can be ruled out
each day. By late Sunday night into early next week, the ridge is
forecast to erode as it is replaced by an upper-level trough that
moves in from the north-northeast. In the meantime, a broad
surface low and tropical wave will increase low-level moisture
convergence over the region, favoring a wetter weather pattern
that could hold through at least mid week. Although there is
medium confidence in this forecast due to timing uncertainties and
dependence on various weather features, interests in the
northeastern caribbean should monitor this tropical wave since any
development of this system could generate hazardous marine
conditions across the region.

Aviation
MainlyVFR conditions are expected to prevail across all
terminals during the next 24 hours. However, shra tsra is expected
to develop over the interior and western sections of pr, which could
cause tempo MVFR conds at tjmz tjps between 18z-22z. Winds will
continue from the east-southeast at 10 to 15 knots with sea breeze
variation through at least 21z.

Marine
Seas continue to improve this afternoon. Wave heights are forecast
to remain around 3-5 feet across the local waters through at least
tomorrow. Prevailing winds persist generally out of the east, with
speeds of 5-15 knots. There is also a continuing moderate risk of
rip currents for northern beaches of local islands today.
