Update Heavy showers and isolated thunderstorms developed once
again over northwest puerto rico during the afternoon hours with 1
to 3 inches observed. Urban flooding was reported in the
municipality of san sebastian. In addition, rio culebrinas once
again went out of its banks across moca and aguada due to the
excessive runoff from the heavy rains. Additional showers were
also observed across the coastal areas of eastern puerto rico and
the san juan metro area with rainfall accumulations of up to a
half an inch observed.

For tonight, conditions are expected to be much quieter across the
area for only a few showers expected, mainly across eastern and
southeastern portions of puerto rico. For Saturday, rainfall
coverage across the area should be less compared to today as a
drier air mass will briefly move overhead. However, moisture
content will still remain sufficient to generate some showers
across eastern and southeastern portions of puerto rico during
the morning hours followed by moderate to heavy showers and
isolated thunderstorms developing across the northwest quadrant of
puerto rico during the afternoon hours as the available moisture
will combine with daytime heating and local effects via sea breeze
convergence and topographical forcing. Given that the soils
across northwest puerto rico remain saturated due to the heavy
rains observed during the last several afternoons, urban and small
stream flooding as well as sharp rises along rivers will remain
possible. Also, mudslides in areas of steep terrain are possible.

Across the u.S. Virgin islands, mainly dry weather conditions can
be expected with just a few brief showers possible at times.

Aviation MainlyVFR conditions are expected across the local
flying area. Shra and isolated TS are expected across western pr
between 25 16z and 25 23z, possibly affecting tjmz and tjbq. This
may result in tempo MVFR to possibly ifr conditions at times.

Winds are expected to be light and variable overnight, increasing
to 10 to 15 knots from the ese with sea breeze variations after
25 14z.

Marine Seas will remain below 4 feet through tonight and will
increase to 5 feet across the atlantic waters and local passages
on Saturday as a small northerly swell arrives. A low risk of rip
currents is expected to continue through tonight. The rip current
risk will be moderate across the north-facing beaches of puerto
rico, culebra, vieques, and saint thomas on Saturday. However,
across the north-central beaches of puerto rico, a high risk of
rip currents cannot be ruled out.

Prev discussion issued 540 pm ast Fri may 24 2019
synopsis... Showers and thunderstorms are expected each afternoon,
mainly over western pr. Moisture peaks on Sunday Monday and once
again on Wednesday. An east to southeast low level wind flow will
prevail for the next several days.

Short term... Tonight through Sunday...

a 45-50 kt westerly flow at 250 mb will continue through the
weekend as an elongated upper level trough forms over the
southwestern caribbean. This will promote high cirrus clouds
streaming across the forecast area through the weekend. At lower
levels, an induced trough over the central caribbean will continue
to move west and promote southeast winds through Saturday. Drier
air is forecast to move briefly ahead of the next easterly
perturbation on Saturday. However, diurnally induced showers with
isolated thunderstorms are still expected to develop mainly over
western pr. Moisture increases once again on Sunday as the
easterly perturbation moves across the caribbean waters and
therefore, scattered to locally numerous showers as well as
thunderstorms will increase across the interior and western
sections of pr as well across the eastern sections of pr. Across
the usvi, as winds increase somewhat during the next couple of
days, diurnally induced streamers are expected to develop each day
off the islands with the best chances for scattered showers on
Sunday.

Long term... Monday through Friday... From prev discussion
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 isold tsra with brief MVFR conds at and vcty

Marine... Seas will increase between 3-5 feet through the weekend
as a small northerly swell moves across the atlantic waters and
local passages. Another second larger swell is expected to move
across the same waters by late Monday night through Tuesday and
seas are expected to increase between 4-6 feet in general. Small
crafts will need to exercise caution. East to southeast winds will
continue between 10-15 kt. A moderate risk of rip currents is
expected across the northern beaches of pr and st. Thomas.

However, a high rip current is possible in isolated coastal areas
of north central pr and a coastal hazard message could be issue
later tonight for this area.

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.
