Synopsis A mid to upper level low northwest of the region will
continue to influence the weather conditions for the next few
days. However, showers and thunderstorms are expected to develop
each afternoon mainly over western pr. Elsewhere, diurnally
induced showers are expected to develop off the usvi from
streamers and over the eastern sections of pr.

Short term Today through Friday...

the mid to upper level trough northeast of the bahamas will
continue to move southeast and remain north of the region through
the short term period. This will continue to provide upper level
support for thunderstorms, mainly over the interior and western
sections of pr today and on Thursday afternoon. On Friday,
although the position of the trough will be unfavorable to provide
divergence aloft... Diurnally induced afternoon showers with
isolated thunderstorms are still expected to develop over western
pr. Precipitable water content is forecast to increase by Thursday
afternoon across the region as a weak induced surface trough moves
from the east and as it interacts with the mid to upper level
trough... The shower and thunderstorm potential could increase
from the usvi to the eastern sections of pr. However, the main
threat for heavy showers with thunderstorms remains over the
interior and western sections of pr.

Long term Saturday through Wednesday...

From previous discussion...

although weather conditions should improve somewhat on Saturday,
early morning showers across eastern pr and the us virgin islands
followed by afternoon convection along and west of the cordillera
central should not be ruled out.

Global models continues to suggest an amplifying trough
interacting with deep tropical moisture early next week, Sunday
through Tuesday. Precipitable water values could range between 1.8
and 2.2 inches through this period. GFS chiclets look reasonable
consistent during the last few runs. Therefore, if these
solutions are correct, unsettle weather conditions could be
expected the first part of the upcoming week. Confidence is
increasing somewhat but continues low-moderate, because still
far in the forecast time. Please continue to monitor the latest
forecast updates during the next several days.

Model guidances continues to suggest a tropical wave moving across
the local caribbean waters by Wednesday.

Aviation Shra tsra across w-pr and nw-pr expected through 22 22z.

several days, with highest seas across the atlantic waters. East
to southeast trades will prevail between 10-15 kt. Sea breeze
variations expected across the western and northern coastal waters

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.
