Area Forecast Discussion
National Weather Service San Juan PR
145 PM AST Sat Nov 19 2016
.SYNOPSIS...A moist and unstable weather pattern will continue
to prevail through early next week as trofiness and plenty of low
level moisture dominates the northeast Caribbean. The potential
for flooding as well as mudslides continues. A Flash Flood Watch
still in effect for Puerto Rico as well as Vieques and Culebra
through Sunday evening.
&&
.DISCUSSION...A mid to upper level ridge will continue to erode
as a trough moves westward into the northeast Caribbean during
the weekend. At lower levels, a frontal boundary north northwest
of the local islands will continue to induce a surface trough as
well as moisture convergence across the northeast Caribbean with
light to gentle easterly winds. As a result through Monday, under
trofiness and moisture convergence, the potential for showers with
thunderstorms will continue to be high. The strongest and widespread
activity will be focused over Puerto Rico during the late morning
through early evening hours due to enhancement associated with
diurnal heating and local effects. During the late evening and
overnight hours, shower and thunder activity is mainly expected
across coastal areas as well as the regional waters. Across
Culebra, Vieques and the U.S. Virgin Islands, expect periods of
scattered showers with isolated thunderstorms mainly overnight
and early morning hours. 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.
As the trough moves away and the moisture convergence zone north
northwest of the area weakens, weather conditions are expected to
slowly improve Tue-Wed. However, precipitable water will remain
above the normal range with locally induced showers and thunderstorms
likely. As a strong surface high establishes across the western
and central Atlantic Thu-Fri, erosion of low level moisture is
expected with mainly fair weather conditions expected to prevail
by the end of the week.
&&
.AVIATION...Expect VFR conditions across most eastern terminals
through the rest of the day...but will mention vicinity showers.
Expect afternoon thunderstorm activity to affect more TJMZ and
TJPS...but will keep VCTS for TJSJ and TJBQ as well.
&&
.MARINE...Seas will continue at 5 feet or less tonight. A northerly
swell around 7 feet will enter the Atlantic waters and Passages
late Sunday and continue through at least Monday. This will result
in hazardous seas and dangerous rip currents along the Atlantic
coastline of Puerto Rico, Culebra and St. Thomas.
