Area Forecast Discussion...UPDATED
National Weather Service San Juan PR
1005 PM AST MON OCT 3 2016

.UPDATE...The 04/00z sounding showed good moisture up through 28
kft, southerly surface flow and strong WNW to NW winds above 35
kft. Most of the convection over the area has quieted into light
to moderate rain. However an area of thunderstorms was entering
the southwest corner of Puerto Rico with frequent lightning as of
04/0053Z.

&&

.DISCUSSION...The gfs appears to be handling the activity the
best and shows activity continuing over the local waters but
weakening-- although not disappearing over the windward coasts
through around 04/12z. Then moisture increases and another round
of convection in distinctly southerly flow will develop and affect
most of Puerto Rico, but particularly the waters just south and
the interior mountain areas. Some thunderstorms are expected but
activity will not be as widespread as the showers. Hurricane
Matthew, will move into the Windward passage by 04/12z and
continue to spread its canopy of mid and high clouds over the area
which will help to limit convection. MOS however is forecasting 90
degrees for the San Juan area and any breaks in the cloudiness
would meet this easily in the southerly flow.

&&

.AVIATION...Mid to Upper level clouds at FL050-120 continue to move
across the flying area. Bands of moisture associated with Matthew
will continue to bring periods of SHRA/TSRA across the local area.
This activity could affect TJPS/TIST/TISX during the overnight hours
and early Tuesday morning. Btwn 03/15-22z the intensity/coverage
should increase to produce brief moments of MVFR or possibly IFR
conds at TJPS/TISX/TJSJ/TIST as well. Elsewhere -SHRA possible. Calm
to light and variable winds overnight increasing at 10 to 15 kt from
the S-SE with higher gusts near SHRA/TSRA.

&&

.MARINE...Hurricane Matthew is expected to send high swell into
the local Caribbean waters. Seas will gradually build from 7 feet
tonight to as much as 10 feet Tuesday night in the western most
waters. This will also generate a high risk of rip currents. A
high surf advisory for the southwestern Puerto Rico coast is being
considered and would be issued tonight for tomorrow if certainty
increases.

&&

.PREV DISCUSSION... /issued 201 PM AST MON OCT 3 2016/

SYNOPSIS...A moist air mass will continue to prevail across
the forecast area during the next few days as Hurricane Matthew...
continues to promote moisture advection across the eastern
Caribbean.

DISCUSSION...Cloudy skies prevailed across the local islands today.
Showers and thunderstorms were observed across the Caribbean waters
with some of them affecting the southern coast of Puerto Rico as
well as Saint Croix. Winds were south southeast at 15 mph or less
with coastal temperatures in the mid to upper 80s.

Hurricane Matthew will continue to promote a south southeast wind
flow across the forecast area which is enhancing deep moisture
transport/convergence across the local island islands. This moist
air mass will continue to prevail through at least midweek.
Therefore expect cloudiness and periods of showers with thunderstorms
and some gusty winds possible over and south of the Cordillera
Central as well as the USVI this afternoon, tonight and Tuesday
mooring. Locally induced showers and thunderstorms north of the
Cordillera this afternoon and Tuesday afternoon is highly
dependent of cloud cover.

Latest guidance suggests precipitable values slightly above the
normal range Wed-Thu, this will result in the seasonable weather
pattern of passing showers across windward areas in the morning
hours followed by afternoon showers and thunderstorms with heavy
rainfall across W and NW PR. A tropical wave is then forecast to
enter the eastern Caribbean on Friday.

AVIATION...Thick clouds causing CIGS at around FL060-080. This
is expected to continue with VCSH/VCTS possible across the local
terminals as the outer bands from Hurricane Matthew move over the
area. S-SE winds of 10-15KT with higher gusts are likely for the
rest of the afternoon, especially near the SHRA/TSRA...decreasing
wind speed overnight. Brief moments of SHRA/TSRA causing MVFR
conds possible at the terminals as well.

MARINE...Small craft advisory for seas up to 7 feet across the
Mona Passage, Caribbean and Atlantic offshore waters, otherwise
small craft should continue to exercise caution across the rest
of the waters due to seas up to 6 feet and southerly winds up to
20 knots. Moderate risk of rip currents continue for much of PR
and St. Croix.
