Area Forecast Discussion
National Weather Service San Juan PR
935 PM AST Mon Jul 17 2017

.UPDATE/NEAR TERM...POPs were adjusted to match current and expected
conditions. Trade wind showers will continue at times. Locally
induced afternoon thunderstorms will continue to prevail each
day across west Puerto Rico. There are two areas of disturbed
weather across the tropical Atlantic which are monitored by the
National Hurricane Center. The first feature likely to pass south
of the area on Wednesday followed by the second feature passing
northeast of the area Fri-Sat.

&&

.AVIATION...VFR conds are expected at all TAF sites overnight
with -SHRA possible at the Leeward and USVI terminals as well as
JSJ. SHRA and TSRA expected aft 18/16z and may result in MVFR
conds in and around JMZ/JBQ through 18/22z. Light and variable
winds overnight, becoming easterly 10-15 knots aft 18/13z with
some sea breeze variations.

&&

.MARINE...No changes to previous discussion, seas are expected to
briefly increase up to 7 feet with occasional seas up to 9 feet
on Wednesday as an area of low pressure moves south of the area.

&&

.PREV DISCUSSION... /issued 350 PM AST Mon Jul 17 2017/

SHORT TERM...Tonight thru Thu...

Shower and thunderstorm activity has now begun over Puerto Rico and
downstream from the U.S. Virgin Islands with low level flow east
southeast. Thunderstorms were first seen over or near Rincon at
17/1745Z. Tops have already surpassed 50 kft there. Activity is
moving into the Mona Channel at this time.

On Tuesday a narrow band of moisture moves through the area in time
for the afternoon heating and better showers are expected. This
followed by a wind surge Tuesday night and Wednesday that is being
generated by a passing low pressure and the high pressure over the
west central Atlantic. The low pressure is Disturbance number 1 that
the National Hurricane Center is giving a 50 percent or medium
probability of development within the next 48 hours. Currently this
is the wave that is located at about 12 north 52 west. It will cross
the ABC islands Tuesday night and south of the local area on
Wednesday. Regardless of development we will actually have drier air
with Saharan dust and better winds--possibly as much as 15-25 mph on
Wednesday. Although some low level showers are possible less are
expected Wednesday than occurred today.

This drier air at 700 mb continues into Thursday, even while patches
of moisture at lower levels move through the area to bring late
night and early morning showers--mainly over eastern Puerto Rico and
around the U.S. Virgin Islands. Better moisture arrives ahead of the
next wave Thursday evening. The next wave is now Disturbance number
2, but it is only given a 20 to 30 percent chance of development
during the period. Hence the main effect will be to bring the area
better moisture as it rides northeast of Puerto Rico and the U.S.
Virgin Islands into the long term period.

LONG TERM...Fri thru Wed /issued 509 AM AST Mon Jul 17 2017/

An area of disturbed weather monitored by the National Hurricane
Center will likely move northeast of the region on Fri-Sat.
Moisture in the periphery of this disturbance will bring scattered
showers over Puerto Rico and the U.S. Virgin Islands late Friday
