synopsis... A strong surface high pressure extending across the
north central atlantic will continue to dominate the local region
today and early Thursday. A tropical wave is forecast to move
across the local forecast area between Thursday and Friday.

Another tropical is expected to move across the caribbean waters
between Monday and Tuesday.

Short term... Today through Friday...

a strong surface high pressure extending across the north central
atlantic will maintain a moderate to locally fresh easterly wind
flow across the region. Under this flow, patches of low level
moisture will enhance shower activity across the region. This
activity will focus over the waters and coastal areas during the
overnight and morning hours. Although a slight erosion of the
available moisture is expected by late morning into the early
afternoon hours, diurnal heating and local effects will still
support the development of showers and isolated thunderstorms during
the afternoon hours, particularly along the interior and over
portions of western puerto rico. Streamer-like showers affecting
eastern puerto rico and the san juan metropolitan area from el
yunque and the local islands cannot be ruled out. However, lack of
upper level support, limited moisture content,and a strong steering
flow will limit the effects this activity may have over these areas.

A slight increase in shower and thunderstorm activity is expected on
Thursday into Friday as the next tropical wave move across the
caribbean and supports moisture advection into the forecast area.

Model-estimated pw values are expected to hold around 1.60 to 2.00
inches by Thursday afternoon and continuing on Friday. Given the
somewhat expected favorable upper level conditions and high moisture
content, there is a better chance for more widespread convection to
develop over the forecast area. As a result, there will be a higher
potential for urban and small stream flooding.

Long term... Saturday through Thursday...

lingering moisture will combine with diurnal heating and local
effects to cause more shower or thunderstorm development across
interior and western portions portions of puerto rico on
Saturday. A drier airmass and saharan dust will prevail over the
local region from Saturday night through Monday. On Monday another
tropical wave would reach the local area but the increase in
moisture with this wave appears to be modest, as much of the
moisture appears to remain south of the local area.

Aviation... Shra affecting usvi and northern pr terminals will
result in brief MVFR conditions through 17 08z. Thereafter, mainly
vfr conditions expected. Vcsh expected at leeward and usvi terminals
throughout the day. Afternoon convection will bring vcts vcsh to
tjmz tjps between 17 15-23z. This could result in brief MVFR
conditions. Light and variable winds through 17 14z, increasing to
15-20 knots with gusts up to 28 knots and turning from the east with
sea breeze variations.

Marine... Passing showers will continue to move across the local
waters through mid morning. These showers could generate wind gust
of between 20 to 25 knots. Mariners should expect winds in the
range of between 10 to 15 knots. Stronger winds could be
experience near the coast due to sea breeze enhancement,
therefore small craft operators should exercise caution along the
northern and southern coast of puerto rico.

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.
