Area Forecast Discussion
National Weather Service San Juan PR
543 AM AST FRI AUG 5 2016

.SYNOPSIS...Tropical wave will move across the area today. Another
tropical wave will affect the region Saturday. Saharan air layer
will encompass the region Sunday into Monday.

&&

.DISCUSSION...An area of scattered to numerous showers developed
this morning across the coastal waters...south of Saint Croix.
These area of showers and thunderstorms were increasing in
coverage. This activity is associated with a Tropical wave which
will continue to move west and will affect the local area today.
Therefore...showers with thunderstorms will spread across the
region this morning across the eastern half of Puerto Rico and
then across the western part of Puerto Rico during the afternoon
hours.

For tonight...a slight decrease in shower activity is
expected...as the wave move away from the area. However...another
fast moving tropical wave will affect the local area late tonight
into Saturday morning. Saturdays wave looks more active than
todays wave...with deep tropical moisture expected to affect the
region. This deep moisture will enhance the shower and
thunderstorm activity across the region. After the passage of
Saturday's wave...a very dry airmass is expected to move across
the region...with Saharan dust affecting the region. In
summary...a wet pattern is expected for today and Saturday..with
drier conditions on Sunday.

&&

.AVIATION...A tropical wave will move across the region producing
periods of SHRA and TSRA across the flying area. Mtn obscuration is
likely across higher elevations. Periods of VCSH/VCTS expected for
USVI and E PR. SHRA/TSRA with possible MVFR cond expected across the
interior and W PR from 16Z-22Z affecting TJMZ/TJBQ. Low level winds
