Synopsis Lingering moisture associated with a departing tropical
wave will continue to produce showers and thunderstorms, mainly
across interior and western puerto rico through late this
afternoon. A more stable weather pattern is expected Wednesday
through Friday, however, sufficient low-level moisture will remain
in place to result in afternoon convection across interior and
western portions of puerto rico. A tropical wave will bring
increased rain chances for Saturday, followed by drier conditions
and saharan dust for Sunday.

Short term Tonight through Thursday...

showers and thunderstorms will continue to affect mainly interior
and western puerto rico through the late afternoon hours before
diminishing through the early evening hours with the loss of
daytime heating. For later tonight, a drier air mass will be
moving overhead. Therefore, more tranquil weather conditions are
expected with just some passing showers expected across the
regional waters and possibly affecting portions of northern and
eastern portions of puerto rico and the usvi. More stable weather
conditions are expected Wednesday and Thursday as an upper-level
ridge builds near the area with very dry air expected in the mid
to upper-levels of the atmosphere. This is expected to limit
rainfall activity across the area compared to previous days.

However, patches of low-level moisture embedded within the
easterly trade wind flow will move across the area from time to
time. This will generate some passing showers during the overnight
and early morning hours across the regional waters and portions
of eastern puerto rico and the usvi with only very light rainfall
accumulations expected. Then, during the afternoon, the available
low-level moisture will combine with strong daytime and local
effects to generate showers and thunderstorms across portions of
the western half of puerto rico.

Long term Friday through Wednesday...

prev discussion... Issued 520 am ast Tue aug 20 2019
a mid to upper level ridge north of the region is expected to
promote fair weather conditions across the islands on Friday.

However, diurnally induced afternoon convection should develop
over western puerto rico. By Saturday, a tropical wave is expected
to increase shower and thunderstorm activity across the region.

At the same time a 700mb high pressure moving from the tropical
atlantic will bring a wind surge behind it and as well a saharan
air layer. Therefore, breezy conditions and hazy skies due to
saharan dust are expected late in the weekend. At the end of the
long term period, a tropical wave is forecast to increase shower
and thunderstorm activity. Both global models are showing
different solutions at this moment. The GFS has a strong tropical
wave entering the southeastern caribbean by Monday morning, while
the ECMWF has a slower solution(including the timing of the 700mb
high) and a weak wave at the end of the period.

Aviation Vcts are expected across tjsj tjps tjbq until 20 22z.

Tempo due to thunderstorms is expected for tjmz until 20 22z. This
could result in MVFR conditions with possible ifr. Vcsh is expected
for the other terminals. Fl050 wind flow will continue out of the
east at 10 to 20 knots.

Marine Mainly tranquil marine conditions are expected to continue
during the rest of the work week with seas of up to 5 feet and winds
up to 15 knots. However, showers and thunderstorms moving off the
west coast of puerto rico during the afternoon may briefly result
in hazardous seas and higher winds. There is a moderate risk of
rip currents for the northern beaches of puerto rico through
tonight.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
