Area Forecast Discussion
National Weather Service San Juan PR
1009 PM AST SAT JUL 30 2016

.UPDATE...A few showers made it inland across the northern half of
PR during the early evening hours. The doppler radar estimated
near three quarters of an inch of rain across the northwestern
municipalities. The tropical wave is expected to move across the
islands on Sunday. Showers and thunderstorms should become more
frequent during Sunday morning through Sunday afternoon. A flash
flood watch will be in effect from Sunday morning through at
least Sunday evening for all local islands. Moisture associated to
the wave will linger through Monday morning. Fair weather conditions
should return by late Monday through Thursday, before the next
tropical wave affects the local area through Friday. Some changes
were made to wind grids, increased winds over waters mainly
between 20-25 knots.

&&

.AVIATION Update...No change from previous discussion. Tropical
wave will increase SHRA and TSRA activity across the waters and
local islands thru Sunday. MVFR CIGS/VSBYS likely across the
Leeward, USVI and E PR overnight and Sunday morning, spreading to
the W PR terminals by Sunday morning and afternoon. Mtn
obscurations likely. Windy cond expected at 10-20 kts with periods
of gusts of 25-35 kts.

&&

.MARINE Update...Marine conditions are expected to quickly
deteriorate as the tropical wave enters the eastern Caribbean
overnight into Sunday morning. Small craft advisories are in
effect for much of the local waters through at least Monday.
Thunderstorms with gusty winds will accompany the wave.

&&

.PREV DISCUSSION... /issued 305 PM AST SAT JUL 30 2016/

SYNOPSIS...Vigorous tropical wave east of the Lesser Antilles
will bring heavy rainfall and gusty winds to the forecast area
tonight into Sunday. This moist and unstable pattern will prevail
through at least Monday afternoon. Drier and more stable air mass
is expected Tuesday through early Thursday. Then...another
tropical wave will reach the local region producing another round
of showers and thunderstorms Thursday night into Friday.

DISCUSSION...Satellite imagery shows a strong tropical wave
approaching the Leewards Islands this afternoon. A large area of
showers and thunderstorms accompanied this wave. Due to the rapid
movement of this feature...the leading edge of the wave will
likely reach the Anegada Passage and the U.S. Virgin islands later
this afternoon and tonight. Shower and thunderstorm activity will
spread over Puerto Rico late tonight into Sunday. At this time...
the best moisture convergence and vorticity advection will move
over the local islands during the day on Sunday. Therefore...A
Flash Flood Watch has been issued for all Puerto Rico and the
U.S. Virgin islands due to the high risk of flooding rains. The
watch is in effect from Sunday morning to Sunday night.

Although the tropical wave will move away from region on Monday
morning...residual moisture in the wake of the wave will keep the
atmosphere relatively unstable through at least Monday afternoon.
Conditions will improve on Tuesday as drier air will filter in
from the east. Weather pattern will remain generally tranquil
through Thursday. Then...Another tropical wave will bring showers
and thunderstorms over the local islands late Thursday into Friday.

AVIATION...An approaching tropical wave will increase SHRA and TSRA
activity across the waters and local islands thru Sunday. MVFR
CIGS/VSBYS likely across the Leeward, USVI and E PR overnight and
Sunday morning, spreading to the W PR terminals by Sunday morning
and afternoon. Mtn obscurations likely. Windy cond expected at 10-20
kts with periods of gusts of 25-35 kts.

MARINE...Marine conditions will deteriorate rapidly later this
afternoon into the evening hours as the tropical wave moves over
the regional waters. Seas will build to 6-8 feet and winds will
increase to around 20 knots with wind gust in excess of 30 knots
possible with the showers and thunderstorms. The most intense
thunderstorms are capable of producing strong gusty winds...
lightning strikes and locally higher waves.
