AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1019 AM AST WED AUG 5 2009

.UPDATE...NO CHANGES TO FORECAST PACKAGE AT THIS TIME. PREVIOUS
SHIFT HAD A GOOD HANDLE ON ONGOING WEATHER CONDITIONS.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL ACROSS ALL TAF SITES
THROUGH THE REST OF THE MORNING HOURS. HOWEVER...MVFR CIGS AT JMZ
WITH VCTS ARE EXPECTED THIS AFTERNOON FROM 17Z TO 23Z. ELSEWHERE
SOME PASSING SHOWERS ARE POSSIBLE.

&&

.PREV DISCUSSION... /ISSUED 417 AM AST WED AUG 5 2009/

SYNOPSIS...A TUTT WITH AXIS ACROSS THE MONA PASSAGE IS TO EVOLVE
INTO A CLOSED LOW OVER HISPANIOLA BY THU. MEANWHILE...TROPICAL
WAVE ALONG 55W TO MOVE ACROSS THE ISLANDS ON THU. STRONG
SUBTROPICAL RIDGE TO BUILD SW INTO THE ERN CARIBBEAN FOR THE
WEEKEND.

DISCUSSION...LOCAL AREA WILL BE ON THE EAST SIDE OF TUTT AXIS
THIS AFTERNOON WHICH TYPICALLY IS A FAVORABLE PLACE OF CONVECTION.
HOWEVER...MOISTURE REMAINS MODEST AT BEST WITH PWAT VALUES AROUND
1.65 INCHES. WHILE THERE WILL STILL BE CONVECTION ON THE WEST THIS
AFTERNOON WIDESPREAD EXCESSIVE AMTS ARE NOT EXPECTED.

TROPICAL WAVE ALONG 55W IS FCST TO CROSS THE AREA ON THU. ALTHOUGH
NO DEEP CONVECTIVE ACTIVITY IS ASSOCIATED WITH THIS WAVE AT THE MOMENT
WAVE IS LIKELY TO GET MORE ACTIVE AS IT APPROACHES PR/USVI AS IT
BEGINS TO INTERACT WITH EAST SIDE OF TUTT LOW FCST TO EVOLVE
ACROSS HISPANIOLA. ALTHOUGH AN INCREASE IN CONVECTIVE CONVERAGE IS
ANTICIPATED WITH THIS WAVE VERTICAL SHEAR WILL REMAIN TOO STRONG
ACROSS THE ERN CARIBBEAN PROHIBITIVE OF TC FORMATION.

BEHIND THE WAVE A WIND SURGE WILL FOLLOW WITH HAZE AND DUST
LIKELY FOR THE WEEKEND. STRONG MID-UPPER LVL RIDGING WILL BUILD ACROSS
THE ERN CARIBBEAN FOR FRI AND SAT LIKELY PUTTING A LID ON
CONVECTION. WAS TEMPTED TO LOWER POPS FOR FRI AND SAT AS AIR MASS
LOOKS BONE DRY. IN ANY CASE...EXCELLENT BEACH WX EXPECTED FOR THE
WEEKEND.

REST OF THE TROPICAL ATLC REMAINS QUIET WITH NO THREAT AREAS TO
DISCUSS.

AVIATION...MVFR CIGS AT JMZ WITH VCTS. REST OF THE TAF SITES
SHOULD REMAIN VFR WITH ONLY VCSH AT BEST. GREATER SHRA/TSRA CVRG

THE WEST.

THU NIGHT BEHIND TROPICAL WAVE WITH SCA LIKELY FOR AMZ710 AND 732.
