Area Forecast Discussion
National Weather Service San Juan PR
958 PM AST FRI MAY 13 2016

.UPDATE...Showers and isolated thunderstorms continued to
redevelop and move northwest across portions of the northern half
of Puerto Rico and the near shore coastal waters during the late
evening hours. Some of the showers over land produced periods of
locally heavy rainfall which lead to minor flooding of roadways...
poor drainage areas and small streams. However...expect the shower
activity over land to continue to diminish within the next couple
of hours leaving partly cloudy to variably cloudy skies. No significant
changes made to the inherited forecast package at this time. Overall
the surface winds will continue from the southeast with model guidance
suggesting the 850 to 700 millibar winds to become more southerly allowing
for lesser moisture advection and some drying in the low to mid levels
over the weekend. However sufficient moisture available to combine with
diurnal and local effects to allow for formation for showers and isolated
thunderstorm along the northern half of Puerto Rico once again on Saturday.

&&

.AVIATION...SHRA will continue to stream northwestward across the
flying area. TJSJ will experience tempo MVFR conds thru at least
14/03Z as a line of SHRA downstream of El Yunque will continue to
affect the vc of the airport. Elsewhere mostly VFR conds expected
overnight. Then...SHRA/TSRA expected once again in the afternoon
along the Interior...West and NW PR...affecting TJBQ/TJMZ and
possibly TJSJ between 14/17-22Z. Mtn top obscd likely with the
SHRA/TSRA. ESE winds around 15 kt will prevail below FL100.

&&

.MARINE...Seas up to 6 feet mainly over the offshore Atlantic and
5 feet or less elsewhere. East Southeast winds up to 20 knots across
the local waters overnight. Small craft should exercise caution over
the local Atlantic waters. Showers and isolated thunderstorms with
areas of heavy rainfall and occasional lightning strikes will also
remain possible over parts of the local Atlantic waters overnight.

&&

.PREV DISCUSSION... /issued 204 PM AST FRI MAY 13 2016/

SYNOPSIS...a high pressure ridge centered to east of the Lesser
Antilles will continue to produce a west-southwest wind flow
aloft. A mid level ridge is forecast to develop and expand
westward over the Eastern Caribbean during the weekend. weak high
pressure north of the local region will merge with another high
pressure over the Central Atlantic over the next few days. This
feature will result in breezy conditions across the islands
Tuesday and Wednesday.

DISCUSSION...abundant moisture will remain across the local
islands tonight and during the rest of the weekend. Precipitable
Water will remain near or above 2.00 inches for the next several
days decreasing to well below 2.00 inches on Tuesday next week. This
high moisture content will keep the atmosphere fairly unstable
at low to mid levels. As a result...showers and thunderstorms
are expected to develop across portions of PR and the USVI
this afternoon and early this evening.

Even though moisture content will remain high for the next
several days...no synoptic forcing will be presented to support
organized convection. however...partly cloudy to mostly cloudy
skies with scattered showers are expected across eastern sections
of Puerto Rico...Vieques...Culebra and USVI each night...followed
by scattered showers and a couple of thunderstorms across western
and interior sections of puerto rico each afternoon. A drier and more
stable air mass is forecast to encompass the local area between
monday and wednesday...reducing the coverage of showers across the
forecast area.

AVIATION...only VCSH expected at TNCM/TKPK/TIST and TISX
terminals thru the rest of the afternoon and evening hours.
SHRA/TSRA are expected to develop north of Cordillera Central
this afternoon...inducing periods of MVFR across TJSJ/TJMZ and
TJBQ until 13/22Z. Therefore...Mtn obscuration across expected
over interior and NW sections. Low level winds will continue from
the E-ESE at 10-15 kt with sea breeze variations.

MARINE...Relatively quiet marine conditions are expected for
the next few days...with seas up to 5 feet and east southeast
winds up to 20 knots across the local waters. However showers and
thunderstorms may produce brief hazardous marine conditions.
