Synopsis for puerto rico and the uS. Virgin islands waters... Long period northwesterly swell from hurricane maria will continue to promote elevated seas of 4-6 feet, especially across the atlantic waters north and west of puerto rico through midweek. Small craft will need to exercise caution in these waters. Winds will be easterly generally 10-15 knots. A weak tropical wave will continue moving west of the region through tonight, before drier weather and decreased rain chances in its wake prevail over the local waters through midweek. Deeper tropical moisture will promote higher rain chances heading towards the weekend.

Aviation
Outside of a few isolated to scattered showers and storms
associated with a weak tropical wave passing by, generally dry
weather should prevail at the TAF sites through the period as a
drier airmass moves in from the east.VFR flying conditions will
likely prevail outside of any brief restrictions in and around
thunderstorms. Winds will be easterly around 10 knots, decreasing
to 5-10 knots overnight.

deep tropical moisture in association with a passing weak tropical
wave will continue to promote isolated to scattered showers and
thunderstorms through tonight. With the loss of daytime heating,
heavy rainfall concerns from thunderstorms should be minimal, but
will continue to watch trends given saturated antecedent
conditions.

Beginning tomorrow, model guidance is in good agreement that a sal
layer will move over puerto rico and the u.S. Virgin islands,
bringing a period of much-needed weather relief to the region.

Generally dry weather will prevail Tuesday and Wednesday, but
cannot rule out isolated convection, especially along terrain-
driven and island wake boundaries, with tropical moisture
remaining firmly entrenched across the region. Still, this period
will promote a favorable respite in the weather pattern, and
should help the recovery efforts across puerto rico and the u.S.

Virgin islands.

Deeper tropical moisture will return to the region by Thursday,
with rain chances increasing back towards seasonable norms heading
into the weekend, with scattered showers and thunderstorms. As the
coverage of thunderstorms increases, so will the flooding
potential, so recovery efforts will need to keep a very close eye
on thunderstorms during this period, as additional flooding will
be possible.

Temperatures will be near normal over the next week, but with
decreased rain chances Tuesday and Wednesday, it will feel quite
muggy in the more abundant sunshine for recovery efforts, with
heat indices likely approaching 100 degrees along the coasts and
in low-lying areas.

Marine...

long period northwesterly swell from hurricane maria will continue to
promote elevated seas of 4-6 feet, especially across the atlantic
waters north and west of puerto rico through midweek. Small craft
will need to exercise caution in these waters. Winds will be easterly
generally 10-15 knots. A weak tropical wave will continue moving
west of the region through tonight, before drier weather and
decreased rain chances in its wake prevail over the local waters
through midweek. Deeper tropical moisture will promote higher rain
chances heading towards the weekend.

Beach forecast...

due to a continued long period northwesterly swell from hurricane
maria, a high risk of rip currents continues for all of the
beaches of puerto rico, except along the southeast coast, where a
moderate risk of rip currents is in effect. A moderate risk of rip
currents is in effect for the beaches of the u.S. Virgin islands.

An elevated rip current risk will likely continue through at least
midweek.

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.
