Update Fair weather conditions were observed across the region
throughout the morning hours, with only a few passing showers
affecting eastern portions of pr during the early morning hours.

Dry air at mid to upper-levels will continue to hold firm across
the forecast area today under the influence of a mid to upper-
level ridge. As a result, most of the area should see mostly dry
conditions. Some locally and diurnally induced showers may develop
across portions of western pr this afternoon, however, these
showers should be short-lived and not result in significant
rainfall if they develop.

Aviation MostlyVFR conditions expected across all terminals
throughout the forecast period. Brief MVFR conditions could occur
in any showers that manage to develop in the vicinity of tjbq and
tjmz this afternoon. E-se winds of up 10-15kt with gusts up to
20kt expected through this afternoon. Lighter and more variable
winds expected after 22 00z.

Marine No changes to the previous discussion. Choppy
conditions with seas up to 6 feet and winds up to 20 knots
expected across most of the regional waters. Low to moderate rip
current risk across the area beaches.

synopsis... Upper level ridge will continue to dominate across
the region until at least Monday producing a relatively dry and
stable weather pattern across the forecast area. However, small
areas of moisture embedded in the trades will produce some showers
overnight and during the morning hours with afternoon showers
across western puerto rico. By early next week, moisture and the
chances of showers are expected to increase.

Short term... Today through Monday...

the ridge of high pressure will remain over the area creating
substance which will keep most of puerto rico and the u.S. Virgin
islands dry. An example of how dry the lower levels of the
atmosphere are just last week pw values where averaging between 1.9
to 2.2 inches at this time pwat values are around 1.62 inches across
the region. Although the area is dry now expect moisture to continue
to increase over the next several days with occasional isolate
shower. Temperatures this weekend will range from the mid 80s to
upper 80s with an easterly wind prevailing today through Monday. The
beginning of the work week we start to look east for our next
weather maker the area of low pressure that is positioned NW of the
puerto rico will begin to drop SE which will switch the winds to the
nw and pull moisture over the islands.

Long term... Tuesday through Friday...

an upper level low sinking southeast toward the leeward islands
will pull a 50 knots jet over the area on its western side Tuesday
and Wednesday, but divergence convergence remains mainly neutral
at upper levels even as moisture slowly increases through the
week. This will result in a gradual increase in shower activity by
mid week. Convection is expected to increase even more Friday and
during the upcoming weekend as a tropical wave approaches the
region.

Aviation...VFR conditions prevailing across all terminals at this
time, with the possibility of some terminals falling to MVFR. If
MVFR conditions occur it will be very brief. Sfc winds will be
light to variable early this morning before increasing to 10 to 15
kts out of the E to se.

Marine... Seas up to 6 feet and winds up to 20 knots will continue
across the surrounding waters during the rest of the weekend.

Small craft are urged to exercise caution across most of the
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.
