Synopsis
Scattered showers will continue for the rest of the day, with the
potential for heavy rain and frequent lightning in the stronger
thunderstorms. Thereafter, a large area of drier air will move in
for the beginning of next week and last into Tuesday. A tropical
system has developed in the atlantic and it is forecast to move
into the eastern caribbean next Wednesday. Though uncertainty is
high, active weather is likely for the middle to end of the week.

Short term Today through Monday
goes-16 IR shows a shallow patch of moisture moving across the
leeward islands. This moisture is associated with a weak tropical
wave that has moved into the caribbean waters this morning. This
wave will continue to move through the region through early Sunday
morning. This tropical wave will produce isolated to scattered
showers this early afternoon across the u.S. Virgin islands and
eastern areas of puerto rico. Most of these showers, however,
should be brief and only lead to minor rainfall accumulations.

Later this afternoon the moisture is expected to continue to
advance to the west. The combination of low-level moisture, local
effects and diurnal heating will initiate showers and isolated
thunderstorms across the interior, western and metro areas of
puerto rico.

In addition, 00z high-res WRF model develops streamers downwind of
the u.S. Virgin islands and across metro areas of san juan this
afternoon. Streamers that do develop could cause urban and small
stream flooding especially if they develop over san juan metro areas.

Sunday, moisture will linger across the area and induce isolated to
scattered showers across most of the region. Then a dry saharan air
mass is forecast to advance into the u.S. Virgin islands and eastern
puerto rico late in the afternoon. This dense air layer will limit
shower activity across the aformentioned areas late Sunday
afternoon. The saharan air will continue to progress to the west
across other areas of the island by Sunday evening resulting in hazy
skies and limited shower activity late Sunday evening into Monday
night.

Long term Tuesday through Friday
dry air and limited showers continue Tuesday, after which our
attention turns to tropical depression 5, which is expected to
move into the eastern caribbean Wednesday morning and through
at least Friday morning. At this point, the system is roughly 800
miles ese of barbados, and moving to the west. There is a high
degree of uncertainty in the track, and especially intensity of
this system as it nears. Most forecast models suggest the system
will move to the south of puerto rico as a tropical depression or
weaker. However, the national hurricane center does suggest this
system has the potential to reach hurricane strength. Those in the
region should monitor our facebook and twitter pages, and the nhc
website

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.
