Update An isolated thunderstorm remains over the coastal
waters of northwestern pr close to aguadilla isabela. This
thunderstorm could continue over the atlantic waters for the next
hour or two. Elsewhere, isolated showers were moving over the
eastern and coastal areas of northern pr. However, no significant
rainfall is expected at the moment over these areas. Meanwhile, a
tropical wave interacting with favorable upper levels is expected
to increase shower and thunderstorm activity over the local
waters and islands through the morning hours of Monday and
continue through the day. Periods of urban and small stream
flooding are expected on Monday with the heaviest showers.

Especially across the interior and western sections of pr due to
already saturated soils. No major change from previous
discussion.

Aviation Tropical wave moving across the eastern caribbean will
result in shra tsra across the local flying area overnight through
Monday. MVFR conds possible through the forecast period across all
terminals. Early on Monday morning across the leeward usvi eastern
pr terminals... Then spreading across all terminals after 29 16z.

Latest tjsj sounding indicated ene winds below fl020 at 8-16
kts... Bcmg ese thru fl100 and W above.

Marine Latest buoy readings across the coastal waters of the
islands were indicating seas between 2-4 feet and east-northeast
winds around 15 kts. As the tropical wave moves across the
caribbean waters, winds will increase up to 20 knots overnight as
well as shower and thunderstorm activity. No change from previous
forecast.

Prev discussion issued 352 pm ast Sun may 28 2017
synopsis... A mid to upper level long wave trough will continue
to extend from the central atlantic southwest to central caribbean
with diffluence flow aloft over the eastern caribbean. A tropical
wave over the eastern caribbean moving west at around 20 kts.

Satellite images showed scattered showers and thunderstorms
associated with this wave spreading over the northern windward
islands and the leeward islands.

Short term... Tonight through Tuesday night... Will expect leading
edge of tropical wave to start affecting the u.S. Virgin islands
late tonight with showers isolated thunderstorms spreading
gradually westward across eastern pr toward morning. Models are
now indicating the wave moving faster with most active portion
affecting the local islands during Monday and Monday night. Upper
level divergence diffluence associated with the upper trough
should enhance the shower thunderstorm activity as the two systems
come into phase over the local islands. To that respect, decided
to increase the chances for rain to indicate numerous showers and
isolated thunderstorms Monday with a gradual decrease on Tuesday
as the wave moves west of the area. Although widespread flooding
is not anticipated... These showers thunderstorms could result in
localized flooding in areas where the ground is already saturated
due to recent rains. We will continue to monitor the situation.

Long term... Wednesday through Monday... Although the wave should
be west of our area by Wednesday, abundant moisture should
continue behind the wave. The mid upper level trough should
continue across the eastern caribbean keeping all areas from pr
eastward under rather unstable conditions supporting the
development of showers and thunderstorms across the local area at
least through Saturday. Another tropical wave could approach the
region by Sunday with a further increase in the chance for rain.

Aviation... PrevailingVFR across the terminals except for tempo MVFR conds at
tjmz possible through 28 20z. Winds from the east to ese at about
15kt with sea breeze variations and occasional gusts today. Shra
will increase late tonight due to approaching tropical wave causing
at least vcsh vcts across the local terminals except for tjmz and
tjbq late tonight into Monday morning. Winds remaining from the east
overnight and Monday morning. More persistent shra and tsra across
the general area after 29 16z which will affect the local
terminals.

Marine... Seas are expected to remain between 2 to 5 feet and
winds of 15 knots or less in most areas through tonight. Winds
and seas could increase Monday and Monday night as the tropical
wave move across our coastal waters. Although a small craft
advisory is not anticipated... Mariners are advice to exercise
caution as winds and seas could be locally higher in the vicinity
of thunderstorms.

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.
