Area Forecast Discussion
National Weather Service San Juan PR
215 PM AST Tue Nov 22 2016

.SYNOPSIS...
Trough aloft will continue to weak over the region today. At low
level, a frontal boundary/shear-line and above normal moisture
will continue to enhance showers and possibly one or two
thunderstorms across the region this afternoon. Weather conditions
are expected to slowly improve during the rest of the week and
into the upcoming weekend, as a ridge aloft builds over the region
and a relative dry air mass encompass the region. However, the
lingering moisture combined with the diurnal heating and local
effects will be enough to result in the typical trade wind showers
during the overnight and early morning showers, followed by
showers and thunderstorms along and to the west of the Cordillera
Central each afternoon.

&&

.DISCUSSION...
Cloudy skies prevailed over the region today, as a mid to upper
level cloud layer moved across the islands. For the rest of this
afternoon, showers with isolated thunderstorms are likely to
continue across Mainland Puerto Rico, but the strongest activity
is expected along the interior and western sections of Puerto
Rico, as well as across the San Juan Metro-Area. Due to already
saturated soils, potential for urban and small stream flooding as
well as sharp rises along rivers continues. Mudslides in areas of
steep terrain is likely.

Although, weather conditions will continue to slowly improve during
the rest of the work week and into the upcoming weekend, above
normal surface moisture will result in locally induced showers and
isolated thunderstorms each day across the region. Particularly,
along the east half portion of Puerto Rico and the U.S. Virgin
Islands during the overnight and early morning hours. Followed by
afternoon convection along and to the west of the Cordillera, but
decreasing each day.

&&

.AVIATION...
MVFR conds in SHRA/ isolated TSRA as well as mountain
obscurations will remain possible at all PR sites through the
forecast period as a weakening trof moves away. Across the Leeward
and USVI terminals mostly VFR conds with VCSH. ESE winds 10 knots
or less becoming light and variable overnight.

&&

.MARINE...Marine Conditions will continue to slowly diminish over
the Atlantic Waters tonight, but winds are to gradually increase
across the offshore shore Atlantic waters through Friday as the
local pressure gradient tightens. This will lead to choppy seas.
