Area Forecast Discussion
National Weather Service San Juan PR
211 PM AST TUE OCT 4 2016

.SYNOPSIS...A moist air mass will continue to prevail across the
forecast area during the next few days under a southeasterly wind
flow. Next tropical wave expected on Friday.

&&

.DISCUSSION...Cloudy skies prevailed across the local islands today.
Showers and thunderstorms were observed across the Caribbean waters
and Mona Passage with some showers and thunderstorms developing
over and northeast of the Cordillera Central. Winds were southeast
at 15 mph or less with coastal temperatures in the mid to upper
80s.

A surface high pressure across the central Atlantic and Hurricane
Matthew across the north central Caribbean will continue to
promote a southeast wind flow across the forecast area during the
next few days. This wind flow is enhancing deep moisture
transport/convergence across the local islands. Therefore still
expect cloudiness and periods of showers with thunderstorms and
some gusty winds over and north of the Cordillera Central and the
USVI this afternoon followed by a few passing showers across
windward areas overnight.

Although latest guidance suggests precipitable water decreasing
somewhat across the local islands on Wed, PW values will continue
to be slightly above normal. Therefore continue to expect passing
showers across windward areas in the morning and afternoon
showers and thunderstorms with heavy rainfall across W and NW PR
Wed-Thu.

A retrogressing TUTT will then move to the eastern Caribbean on
Thursday to Friday. At low levels this will coincide with tropical
wave entering the forecast area on Friday. Therefore the chance of
showers and thunderstorms will increase by the end of the week and
into the upcoming weekend.

&&

.AVIATION...Moisture under the canopy of Hurricane Matthew has been
slow to generate convection. A band of convergence, with +SHRA/+TSRA
however passes from just west of Fajardo to just east of saint Croix
and is moving slowly west with MVFR conds and mtn obscurations.
Expect slow development of SHRA/TSRA over interior and western PR
til 04/22z. VFR condtions are expected to continue in TIST and the
Leeward islands, but SHRA/TSRA north of Saint Croix and apchg from
SE will continue to keep areas of lwr CIG/VSBYS VCNTY. Area winds
alf Sly sfc thru FL 120 10 to 20 kt. Upper winds FL350-500 NW 30 kt
incrg to N at 50 kt by 05/18z.

&&

.MARINE...A swell generated by the wind field of Hurricane Matthew
is producing 8-10 feet breaking wave heights and rip currents
across the beaches of St Croix, West and South Puerto Rico. Seas 8
to 10 feet with occasional seas up to 11 feet. Marine condtions
will slowly improve Wednesday afternoon.
