Synopsis for puerto rico and the uS. Virgin islands waters... A weak surface trough moving across the caribbean waters will increase the potential for showers and Thunderstorms through the afternoon hours. A moderate east to southeast wind flow will continue across the region for the next several days. Seas will increase up to 5 feet across the atlantic waters and passages on Saturday due to a small northerly swell. A second larger, northerly swell is forecast to arrive across the atlantic waters by early next week. Isolated Thunderstorms are expected each afternoon mainly over the western waters of puerto rico.

Update
A fairly moist southeasterly winds flow across the region, along
with the proximity of a mid to upper level trough and subtropical
jet segment will continue to favor a fairly wet weather pattern
across the region at least through Saturday. Somewhat improving
conditions so far expected Sunday and Monday as the upper trough
weakens and lift northwards. Still however expect local and diurnal
effects along with lingering tropical moisture, to support showers
and isolated thunderstorms development across parts of the
islands each afternoon.

For the rest of today expect shower and thunderstorm development
to be focused over central and northwest sections of puerto rico.

However isolated showers will remain possible elsewhere including
around the u.S.Virgin islands. Urban and small stream flooding
will remain possible especially in the northwest and along the
north coastal areas of pr into the early evening hours. No changes
made to the inherited short term forecast package at this time.

Marine update No significant changes made to the previous marine
discussion at this time. Wind and seas 10 to 15 kts and 4 feet or
less respectively during the rest of the day and overnight. Slight
increase in winds and seas still expected over the upcoming
weekend due to arrival of northerly swell action.

synopsis...

a mid- to upper-level low will dominate local weather conditions
through early this weekend. Plenty of tropical moisture will
continue across the islands through at least next week. Shower and
thunderstorm development is likely each day across portions of the
islands.

Short term... Today through Sunday...

a mid to upper level trough continues to be the dominant feature
during the short term forecast period. Model guidance suggests that
this system will cross the forecast area today, maintaining somewhat
favorable conditions aloft. These conditions combined with
sufficient moisture content--model pw estimates of 1.90 inches--will
support the development of showers and thunderstorms. This activity
is forecast to cluster over the waters during the morning hours and
along the interior and northwestern quadrant of puerto rico in the
afternoon. Showers and thunderstorms affecting the san juan
metropolitan area cannot be ruled out. Rainfall accumulations
between 1-2 inches with isolated higher amounts are expected with
this activity. That said, the potential for urban and small stream
flooding, as well as mudslides near areas of steep remains remains
elevated today.

Conditions aloft are to gradually turn unfavorable as the mid to
upper level trough continues to drift eastward and away from the
region tonight and continuing into the weekend. Although the
intensity and areas coverage of showers and thunderstorms are
expected to diminish during the weekend, sufficient moisture content
supported by diurnal heating and local effects will enhance the
development of localized afternoon convection across the interior
and western sectors of puerto rico each day. Rainfall accumulations
are forecast to peak at 1.0-1.5 inches on Saturday and 0.5-1.0
inches on Sunday with isolated higher amounts. Although with a lower
potential, the threat for urban and small stream flooding will
continue during the weekend.

Long term... Monday through Friday...

although a mid- to upper-level ridge is forecast to build across
northeast caribbean, plenty of tropical moisture will move from
the caribbean sea into the local region increasing the potential
for showers and locally induced thunderstorms Monday and Tuesday.

Model guidance continues to indicate a weak tropical wave moving
off to the south across the caribbean sea by Wednesday or
Thursday. Another mid- to upper-level trough is forecast to
amplify near the region Thursday and Friday. If models are
correct, a wet pattern with favorable conditions for shower and
thunderstorm development may be possible next week.

Aviation... Shra tsra will result in vcsh vcts conds and brief MVFR
conditions at tjps, usvi and leeward terminals through 24 14z.

Similar conditions with brief MVFR conds possible are expected at
tjsj between 24 14-18z and tjmz tjbq after 24 18z. Bkn to ovc
between fl020-040 expected with this activity. Light and variable
winds through 24 14z, turning from the ese at 10-15 kt with sea
breeze variations and occasional gusts after 23 14z, particularly
near shra tsra.

Marine...

mariners can expect seas around 4 feet across most of the local
waters. A small northerly swell will persist across the atlantic
waters through at least Saturday. Trade winds will continue from
the east to southeast between 10 and 15 knots, although local
effects will promote higher winds up to 20 knots each afternoon. A
northerly swell will move across the atlantic waters early next
week. There is a moderate risk of rip currents for some north
facing beaches of puerto rico.

Thunderstorm formation are expected across portions of the
coastal waters of puerto rico and the u.S. Virgin islands.
