Synopsis for puerto rico and the uS. Virgin islands waters... A surface high pressure across the western and central atlantic, will continue to yield moderate to fresh trade winds across the region during the next several days. This will result in choppy seas across the regional waters and local passages. Increasing winds and seas are forecast for the offshore caribbean waters and the Mona passage Wednesday through Friday.

Synopsis
Suspended saharan dust particles will result in hazy skies through
at least Friday. A surface high pressures across the atlantic
waters will result in breezy easterly trade winds across the
region. Patches of moisture embedded in the trades will bring
passing showers across the windward sections each day, followed
by afternoon convection across the western sections. A tropical
wave will move across the eastern caribbean by late Wednesday
night into Thursday.

Short term Today through Wednesday...

a low to mid level high pressure extending over the atlantic will
maintain a moderate to fresh east to southeast wind flow across the
region. Under this flow, an area of drier air accompanied by saharan
dust will continue to move over the forecast area from the east,
resulting in mostly fair weather conditions and hazy skies through
the short term forecast period. So far, model estimated precipitable
water peak around 1.60 inches by early Monday afternoon, but
dropping between 1.40-1.50 inches on Tuesday and Wednesday.

Regardless of these conditions, locally induced showers and isolated
thunderstorms may still develop over portions of western puerto rico
each afternoon. Overnight and morning showers streaming over the
waters into coastal areas of eastern puerto rico and the u.S. Virgin
islands are also possible, but limited. However, significant
rainfall accumulations are not expected from this activity since
upper level conditions will not support deep convection and a strong
steering flow will shorten the time showers remain over a specific
location.

Recent model guidance suggests that a tropical wave moving across
the eastern caribbean will begin to draw a plume of moisture across
the forecast area late Wednesday night. Although this high moisture
content will increase shower and thunderstorm activity across the
area, this activity will remain over the waters by the end of the
short-term forecast period. The long-term forecast discussion will
include additional information on the effects of this tropical wave
across the forecast area.

Given the expected dry conditions with mostly clear and hazy skies,
seasonably warm temperatures can be expected with highs reaching the
upper 80s to low 90s with heat index peaking at 103-105f across at
lower elevations, particularly across urban areas.

Long term Thursday through Monday...

model guidance continues to suggest a ridge pattern at mid- to
upper-levels through at least Sunday. Then, a tutt-low is forecast
to amplify over cuba and dominican republic weakening the ridge
pattern over puerto rico and the u.S. Virgin islands by Monday. In
addition, a saharan air layer with suspended saharan dust
particles is forecast to linger across the islands through at
least Friday. As a result, hazy skies will be likely through the
work-week. Another tropical wave will move over the eastern
caribbean by late Wednesday night or Thursday, which could
increase the potential for showers and thunderstorms development
on Thursday.

Under the aformentioned atmospheric pattern, trade wind showers
should not be ruled out each day across the windward sections of
the u.S. Virgin islands and puerto rico. Locally induced showers
and thunderstorms will remain possible each afternoon across
western puerto rico. The best chance for shower and thunderstorm
development seems to be on Thursday with the arrival of the
tropical wave. A second tropical wave will move across the
eastern caribbean sea on Sunday. Atmospheric instability could
increase by Monday as the ridge pattern aloft weakens.

Aviation
MainlyVFR conditions will prevail during the next 24 hours.

However, shra will result in vcsh across the terminals of
usvi leeward islands through at least 17 14z. Afternoon convection
will bring shra tsra to tjmz tjbq between 17 16-22z, which could
result in brief MVFR conditions. Light and vrb winds expected
overnight. Breezy conds expected after 17 14z with the e-se winds
between 15 to 20 knots and gusts up to 30 knots.

Marine
The local buoy network was indicating seas between 3 and 4 feet,
except in rincon were seas are below 2 feet. Winds were between 10
and 16 knots across the near-shore waters of puerto rico and the
u.S. Virgin islands. A surface high pressure across the atlantic
ocean will continue to bring a moderate to fresh easterly trade
wind flow through much of the week. Mariners should exercise
caution across the local waters due to seas up to 6 feet and winds
between 15 and 20 knots.

Marine guidance continues to suggest an increase in winds and
seas by mid-week. Therefore, small craft advisory criteria will be
likely by that period, especially across the outer caribbean
waters and the mona passage.
