Update near term Locally induced showers and thunderstorms are
still expected this afternoon across west puerto rico. However,
this activity should be short-lived as a drier air as well as
subsidence ahead of an approaching tropical wave encompass the
forecast area this evening into tonight. Moisture associated with
the approaching tropical wave is expected to reach the area tomorrow.

Minor changes were introduced to the near term grids at this
time.

Aviation Vfr conds expected to prevail at all TAF sites with
brief MVFR conds in shra tsra at jmz between 28 16z and 28 22z.

Easterly winds 10-15 knots with sea breeze variations expected
through 28 22z, becoming at 10 knots or less overnight. Cloudiness
and shra tsra activity will increase across the leeward terminals
overnight.

Marine Tranquil marine conditions will continue to prevail
across the regional waters with seas up to 4 feet and winds 15-20
knots. Winds and seas will increase across the area tonight into
Thursday as a tropical wave moves across the eastern caribbean.

This will also increase the chance for showers and thunderstorms.

Prev discussion issued 501 am ast Wed jun 28 2017
synopsis... A tropical wave will move across the area Thursday and
Friday increasing the shower and thunderstorm activity across the
area. A drier air mass will encompass the region behind the wave
during the weekend.

Short term... Today through Friday... The upper low to the north
northeast of the local area will remain over the central atlantic
for the next few days while a weaker upper low develops just north
of the local islands late Wednesday into Thursday. There is also
a strong sfc high across the north central atlantic which will
also prevail for the next few days. Saharan dust is present and
will affect the local area today so there will be some haze.

However, just like it was the case yesterday, showers and isolated
thunderstorms are expected this afternoon across western pr.

Thursday and Friday are expected to be more active as a tropical
wave approaches the local area late on Thursday, increasing the
available moisture significantly and causing much more coverage of
showers and thunderstorms when combined with the upper low just
north of the local islands late on Thursday into Friday.

Long term... Saturday through Thursday... Saturday and Sunday, a
dry airmass will dominates the region before a tropical wave
affect the local area Monday. Another dry airmass is forecast by
computer models to encompass the region from the east by mid next
week, with patches of low level moisture embedded in the trade
winds affecting the region throughout the period.

Aviation...VFR conds expected for the next 24 hours across the
local terminals. Vcsh is expected early in the morning for tist,
tisx, and tjsj. Afternoon convection is expected mainly across the
western sections of pr, which could affect tjmz and cause tempo MVFR
conds after 28 18z. Saharan dust is still present, causing haze but
visibility will still be p6sm. Winds from the east at 5-10kt
expected early this morning, increasing to about 15kt with
occasional gusts after 28 13z.

Marine... Seas up to 5 feet and winds up to 20 knots are expected
across the coastal waters. Small craft should exercise caution
across the atlantic and caribbean nearshore waters due to winds.

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.
