Update Showers and thunderstorms were observed across puerto
rico this afternoon, but mostly dissipated late in the afternoon.

The showers caused urban and small stream flooding as well as
river rises. Then, for tonight, isolated to scattered showers are
expected across the local waters, which could briefly affect the
usvi and eastern pr during the night. Tropical wave expected to
bring an increase in moisture and cause scattered showers across
the local waters, usvi and eastern pr in the morning hours, then
the moisture will combine with diurnal heating and local effects
to cause showers and thunderstorms over portions of puerto rico,
with the heaviest showers across the northwestern quadrant of
puerto rico. Given the amount of rain observed today across that
area and the impact it had, it would not be out of the realm of
possibilities to see additional urban and small stream flooding
tomorrow afternoon across nw-pr and maybe even some rapid river
rises.

Aviation Vfr conds overnight across the local terminals with
vcsh at the tist tisx tjsj terminals. Sct shra across the area
will continue to cause vcsh through the day, then tsra expected to
develop after 22 15z near tjsj and after 22 17z near tjmz and
tjbq. Winds will be from the east at around 10kt or less
overnight, increasing to 15kt and gusty after 22 13z with sea
breeze variations developing as well.

Marine Seas will be generally up to 4 feet and winds up to 15
knots overnight. Winds will increase up to 20 knots in some areas
on Wednesday and seas may increase to 5 feet. There is a moderate
risk of rip currents across some of the local beaches, especially
across norther puerto rico and eastern and southern saint croix.

Prev discussion issued 507 pm ast Tue aug 21 2018
synopsis... Surface high pressure over the central atlantic will
promote a moderate east wind flow across the region for the next
several days. A weak tropical wave will move on Wednesday.

Seasonable weather conditions return during the second part of
the work week, with mainly diurnally induced shower activity over
western puerto rico. Another tropical wave is forecast to enter
the eastern caribbean by next Tuesday.

Short term... Today through Thursday...

a weak tropical wave located just east of the lesser antilles will
move on Wednesday across the forecast area. The upper level ridge
will continue to weaken as an upper level trough builds northeast
of the region. The wave will enhance diurnal activity and showers
and thunderstorms are expected to develop along the cordillera
central and over western puerto rico. Urban and small stream
flooding is expected with this activity. Mudslides in areas of
steep terrain are also possible with the heaviest showers. Drier
air is expected to fill in from the northeast on Thursday and this
will limit widespread convection across the region. However,
diurnally induced afternoon showers with possible isolated
thunderstorms cant be ruled out over western puerto rico.

Long term... Friday through Monday... From prev discussion
although the upper trough is forecast to fill after Thursday,
available moisture in combination with local effects will help
generate scattered to numerous showers over the interior and
western portions of puerto rico every afternoon through the
incoming weekend. Models suggest a better organized tropical wave
moving across the caribbean waters on Tuesday.

Aviation... MainlyVFR conditions expected through 22 15z. Then
shra tsra expected to develop over the interior and western
sections of pr, resulting in tempo MVFR conditions at tjbq tjmz.

Mainly vcsh elsewhere. Low level winds expected from the east at
10-15 kt with higher gusts in shra and in sea breeze variation
after 22 14z.

Marine... Seas should continue to range between 2-4 feet across
the coastal waters of the islands. Seas up to 5 feet are expected
on Wednesday across the offshore waters and passages. East wind
will prevail at 10-15 kt with higher gusts in the late morning afternoon
hours across the coastal waters. Moderate risk of rip currents
continue for the north and south coast of pr as well across the
east southern coast of st. Croix.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
