Update near term Continue to expect showers and thunderstorms
with the potential for urban and small stream flooding today as a
tropical wave moves across the eastern caribbean. Periods of showers
and thunderstorms across the usvi and E pr are expected this morning,
spreading across W pr in the afternoon. Although shower and thunder
activity is expected to decrease across west pr in the evening,
periods of showers and thunderstorms will continue to prevail
across the usvi and E pr tonight.

Aviation Periods of MVFR or even ifr conds will remain possible
at all TAF sites through the forecast period as a tropical wave
and associated shra tsra move across the area. Ese winds at 15
knots but higher in and around shra tsra expected. Wx conds will
slowly improve across the leeward as well as usvi terminals

Marine As a tropical wave continues to move across the forecast
area, seas up to 6 feet and winds 15-20 knots are expected.

Locally higher winds as seas are possible in showers and thunderstorms,
particularly across the caribbean waters.

synopsis... An active tropical wave will move across the area
today bringing with it scattered to numerous showers with
thunderstorms. A very dry airmass will encompass the region

Short term... Today through Saturday... The tropical wave that
is moving in will bring a good amount of moisture to the local
area. This wave will also bring showers and thunderstorms to the
local islands today, lingering possibly until Friday. Although the
shower and thunderstorm activity expected today is not expected
to be constant, periods of moderate to locally heavy rainfall is
expected across many sectors of the local islands. A weak upper
low to the northwest of pr may help in the development of
thunderstorms today, especially if the cloudiness is slow to reach
pr this morning. As of this writing, a line of showers is already
affecting saint croix and additional lines of showers and
isolated thunderstorms will move into the usvi this morning. As
these bands move through the local area in the morning, the
diurnal heating will help cause more instability over pr as the
day progresses, this means that more persistent showers and
thunderstorms are possible over pr today, especially across
western pr where the heating, moisture and local effects will
combine and cause convection over those areas. However, shower and
thunderstorm activity is possible across most of pr. Urban and
small stream flooding is expected across many areas in the local
islands, river flooding will not be ruled out in puerto rico

This deep moisture associated with the tropical wave has
precipitable water values of over 2 inches, and is expected to
linger through Friday. This means that showers associated to this
wave could affect the local islands overnight tonight into Friday as
well, especially for eastern pr and the usvi, then across w-nw pr on
Friday afternoon once again due to the combination of moisture and
local effects. If the rainfall today does in fact have a significant
hydrologic impact across the local islands, the rainfall on Friday
could cause some flooding due to potentially saturated soils.

Weather to improve on Saturday as the wave moves away and the
moisture decreases for the weekend.

Long term... Sunday through Friday... We will see the passage of
tropical waves every three to fours days in the long term. Dry air
will continue over the region Sunday. Another tropical wave is
expected to pass mainly south of the region Monday. It will be
follow by another area of drier air which is forecast to encompass
the region Tuesday. Another wave is forecast by computer models to
affect the area by Wednesday and Thursday.

Aviation... Tropical wave to bring shra tsra to the local area
today. Tempo MVFR and even brief ifr conds are possible with the
activity expected today even though most of the timeVFR conds
should prevail. Bands of shra will affect tist tisx terminals by
29 10z and continue through the day, reaching tjsj by approx 29 14z
and tjmz tjbq by 29 17z. Tjps will probably stay with vcts vcsh.

Winds will be mainly from the east at about 10-15kt with gusts near
the shra tsra. CIGS are expected at around fl050, lower with
shra tsra.

Marine... Seas up to 6 feet and winds up to 20 knots are expected
across the local waters. A tropical wave will produce choppy seas
and an increase in winds across the region. Small craft should
exercise caution across most waters.

These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
