Area Forecast Discussion
National Weather Service San Juan PR
153 PM AST SAT JUL 2 2016

.SYNOPSIS...Tropical wave is over the local area, causing showers
and thunderstorms. Conditions expected to improve tonight as the
tropical wave moves away. Moderate to fresh winds are causing
choppy seas across the local waters. Another tropical wave
expected late Monday into Tuesday.

&&

.DISCUSSION...Numerous showers and isolated to scattered
thunderstorms affected the local area today as a tropical wave
passes through. Some of the thunderstorms had frequent lightning
and brief heavy rain. Although most of the shower and
thunderstorm activity was over the local waters, portions of Saint
Croix and eastern PR were affected with rainfall totals of over
one inch across those areas. The maximum estimated amount of
rainfall was observed over the municipality of Naguabo where over
2 inches of rain are estimated by radar. As of this writing,
eastern PR received more rain than western PR and Saint Croix
received more rain than the northern USVI. Showers and
thunderstorms are expected to continue over the local waters and
gradually become more numerous across western PR.

Drier air is moving in and it can be seen on satellite over the
Leeward islands. It is expected for the drier air to move into the
local area by tonight, which will cause a gradual improvement on
the local weather. So we expect Sunday and Monday to have mostly
fair weather with isolated to scattered brief showers, isolated
brief thunderstorms on Monday, but it may be a bit hazy as Saharan
dust is expected to move in on Sunday.

Another tropical wave is expected to move in late Monday into
Tuesday. This tropical wave is carrying some good moisture and
satellite imagery is showing decent convection. This means that
another round of showers and thunderstorms are expected on Tuesday
as the tropical wave passes. From Wednesday through the end of the
week, drier air moves in once again. In addition, an upper low
moves to the north of the local islands which will position the
local islands in the subsident side of the upper low, so any
convection will probably be locally induced, particularly on
Wednesday.

&&

.AVIATION...The tropical wave will continua to move across the
flying area today, resulting in SHRA and TSRA. SHRA/TSRA expected
across the interior and western sections of PR after 02/16Z, with
periods of MVFR conds for TJBQ/TJMZ possible at times. SHRA/TSRA
activity is expected to diminish after 02/22z leaving just a few
brief -RA mainly across TJSJ/TJPS/TNCM/TKPK/TIST/TISX. East winds
at 10-20 kt with higher gusts near SHRA/TSRA, then calm to light
and variable winds overnight.

&&

.MARINE...Choppy seas expected through the rest of the weekend as
the local moderate to fresh winds cause seas up to 7 feet across
the offshore Atlantic waters and the Anegada passage. The rest of
the local waters could have winds up to 20 knots and seas up to 6
feet, so small craft operators should exercise caution.
