Synopsis Tropical wave will move across the region this
afternoon into Sunday. Tutt low will develop and moves across the
southwest atlantic early next week.

Short term Saturday through Monday...

although a mid to upper level ridge will prevail throughout the
forecast period; there is a chance for showers and thunderstorms
across the local islands this afternoon into Sunday as a tropical
wave moves across the northeast caribbean.

Mostly fair weather conditions will continue to prevail this morning
across puerto rico and the u.S. Virgin islands. However, as a
tropical wave which is now located over the lesser antilles moves
closer to the forecast area, precipitable water is expected to
increase above the normal range. This will assure locally induced
showers and thunderstorms across the interior and western areas of
puerto rico this afternoon followed by passing showers with isolated
thunderstorms across the usvi and E pr this evening throughout
Sunday morning.

Lingering moisture combined with local effect will result in another
round of showers and thunderstorms over and north of the cordillera
central Sunday afternoon. As the wave moves away, a drier air mass
will encompass the forecast area Sunday night into Monday. Urban and
small stream flooding is likely with the heaviest showers.

Long term Tuesday through Sunday...

at upper levels... Tutt low will dominates the northeast caribbean
through Sunday. At low level, a tropical wave will move across
the region Thursday. The combination of these features, with
daytime heating and local effects will result in high chances for
showers and thunderstorms across the local islands during most of
the period.

Aviation Vfr conds are expected to prevail at all TAF sites
through the early morning hours. However, as a tropical wave moves
over the leeward islands, brief MVFR conds are possible at tkpk tncm
late this morning as well as into the afternoon hours. Aft 22 16z
shra tsra expected near jmz jbq with MVFR conds possible through
22 22z. Easterly winds 10-15 knots aft 22 13z with some sea breeze
variations.

Marine Seas up to 6 feet and winds up to 20 knots are expected
to prevail across the local waters. Small craft should exercise
caution across the offshore atlantic waters.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
