NATIONAL WEATHER SERVICE SAN JUAN PR
235 PM AST TUE JUN 4 2013

.UPDATE...APEX OF THE WAVE STALLED OVER THE CARIBBEAN WATERS
SOUTHEAST OF PUERTO RICO. RADAR INDICATED THAT ONE SMALL AREA
RECEIVED ALMOST 14 INCHES OF RAIN SINCE MIDNIGHT. FORTUNATELY
AMOUNTS REMAINED BELOW 2 INCHES OVER SOUTHEAST PUERTO RICO. AND
MANY AREAS OF CENTRAL AND NORTHWEST PUERTO RICO RECEIVED NO RAIN
UP TO NOW. BEST CONVECTION IS NOW SOUTH OF THE FORECAST AREA.
SOUTHERLY DOWNSLOPE WINDS ARE CONTINUING OVER PUERTO RICO AND MAY
BE INHIBITING CONVECTION IN SPITE OF THE APPROACHING UPPER LEVEL
SHORTWAVE WHICH COULD STILL TRIGGER SHOWERS AND THUNDERSTORMS OVER
PUERTO RICO.

AT THIS TIME AM ISSUING A SPECIAL UPDATE TO REDUCE POPS AND
QPF...SINCE CONVECTION THAT COULD BE SUPPORTED WILL NOW BE MUCH
LESS.

&&

.AVIATION...SOME MOUNTAIN OBSCURATIONS WILL CONTINUE...OTHERWISE
CONDITIONS AT TAF SITES ARE EXPECTED VFR.

&&

.MARINE...SEAS CONTINUE TO BE 4 TO 6 FEET IN THE FORECAST
AREA...AND THIS WILL LIKELY CONTINUE THROUGH NEXT 3 TO 5 DAYS AT
LEAST.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
334 PM AST TUE JUN 4 2013

.SYNOPSIS...AT UPPER LEVELS...A SHORT WAVE TROUGH WILL PASS NORTH
OF THE U.S. VIRGIN ISLANDS EARLY THIS EVENING. HIGH PRESSURE WILL
BUILD NORTHEAST OVER CUBA AND THE BAHAMAS WHILE A NEW LOW WILL
DEEPEN AND EXTEND SOUTHWEST OVER PUERTO RICO. THIS LOW MAY DRIFT
WEST TO THE WATERS JUST NORTH OF HAITI BY TUESDAY OF NEXT WEEK WITH
A RIDGE BUILDING OVER THE WINDWARD ISLANDS.

AT MID LEVELS...HIGH PRESSURE OVER THE GREATER ANTILLES WILL MOVE
NORTH OF HISPANIOLA BY FRIDAY WHILE LOW PRESSURE FORMS WEAKLY
NORTHEAST OF THE LEEWARD ISLANDS. THIS LOW WILL JOIN AN INVERTED TROUGH
AND MOVE OVER TO PUERTO RICO BY SATURDAY NIGHT. HIGH PRESSURE
BUILDS OVER THE ATLANTIC NORTHEAST OF THE AREA DURING NEXT WEEK
AND SPREADS OVER THE NORTHEAST CARIBBEAN.

AT LOWER LEVELS...THE APEX OF A TROPICAL WAVE THAT BROUGHT STRONG
CONVECTION OVER THE CARIBBEAN WATERS OVER THE WATERS AROUND AND
SOUTHWEST OF VIEQUES DISSIPATED LEAVING MOST OF THE CONVECTION TO
THE SOUTH TO CONTINUE MOVING WEST THROUGH THE CARIBBEAN. DRIER
AIR WILL FILTER INTO THE LOCAL AREA TONIGHT AND TOMORROW...BUT A
BAND OF MOISTURE WILL PASS THROUGH WEDNESDAY NIGHT AND THURSDAY
FOLLOWED A DRY SLOT AND ANOTHER TROPICAL WAVE ON SUNDAY.

&&

.DISCUSSION...HEAVY RAIN FELL ALL AROUND THE EAST AND SOUTH OF
PUERTO RICO...INCLUDING OVER VIEQUES. ONE PARTICULAR AREA IN THE
CARIBBEAN 33 MILES SOUTH SOUTHWEST OF THE WESTERN END OF VIEQUES
RECEIVED 10 TO 14 INCHES OF RAIN. THIS TROPICAL WAVE IS MOVING SOUTH
OF THE AREA...BUT SOUTHEASTERLY FLOW STILL PREVAILS AT LOWER
LEVELS AND SOUTHERLY FLOW AT MID LEVELS. THIS HAS CAUSED CONSIDERABLE
DOWN-SLOPE FLOW THAT HAS BOTH WARMED AND DRIED THE AREA NORTH OF
THE CORDILLERA CENTRAL MAKING CONVECTION SCARCE. THE HIGH IN SAN
JUAN REACHED 89 DEGREES. MAYAGUEZ ALSO REACHED 91. AN UPPER LEVEL
TROUGH IS STILL APPROACHING THE LOCAL AREA...TO PASS BEFORE
MIDNIGHT. THIS MAY CAUSE SOME SCATTERED CONVECTION...BUT AT PRESENT
THE HEAVIEST RAIN HAS ALREADY FALLEN EAST OF THE ISLAND. BEGINNING
TONIGHT...DRIER SAHARAN AIR IS EXPECTED BEHIND THE WAVE WEDNESDAY
THROUGH FRIDAY. SOME THUNDERSTORMS ARE TO BE EXPECTED EACH DAY IN
THE WESTERN PARTS OF THE ISLAND IN THE AFTERNOONS. PRECIPITABLE
WATER BEGINS INCREASING THURSDAY NIGHT FROM A LOW OF AROUND 1.35
REACHING 1.8 INCHES BY SUNDAY WHEN ANOTHER TROPICAL WAVE IS
EXPECTED TO PASS BY.

&&

.AVIATION...
SCT SHRA/ISOLD TSRA MAY STILL OCCUR THIS AFT ACROSS PR
MTNS WITH OBSCURATIONS. BUT THE WINDOW FOR THIS TO BEGIN IS CLOSING QUICKLY AS
THE SUN GETS LOWER. LESS THAN VFR CONDS APPEARS UNLIKELY ATTM AT TAF
SITES. TIST/TISX/TNCM/TKPK ARE ALREADY IN THE DRY SAHARAN AIR WITH
SOME DUST...WL PERSIST THRU WED. WINDS BLO FL100 SE 15-20 KT BCMG E
10-20 LATE WED.

.SYNOPSIS...UPPER LEVEL TROF EXTENDING NE OF THE LEEWARD ISLANDS
INTO THE ERN CARIB WILL EVOLVE INTO A DEEP TUTT OVR THE WEEKEND
WHILE IT SLOWLY RETROGRADES. SAHARAN AIR LAYER WILL PERSIST
THROUGH SAT.

&&

.DISCUSSION...MAIN HIGHLIGHTS TODAY IS IMPRESSIVE SAHARAN AIR
LAYER FOR SO EARLY IN THE SUMMER BRINGING FIRST SIG DUST HAZE
EVENT OF THE YEAR. MODIS AOD PRODUCT FROM YESTERDAY AND NRL
AEROSOL LOOPER SHOW HAZY SKIES TODAY BUT BECOMING CLEARER AFTER
TODAY.

UPPER LEVEL CONVERGENCE ON BACKSIDE OF UPPER LEVEL TROF AXIS OVR
THE ANEGADA PASSAGE WILL LEAD TO STRENGTHENING OF SUBSIDENCE
INVERSION AND GRADUAL EROSION OF LOW LEVEL MOISTURE THROUGH SAT.

NEXT FEATURE OF INTEREST IS A TROPICAL WAVE LOCATED ALONG 41.5W.
THIS WAVE IS ALSO ACCOMPANIED BY A WEAK SFC LOW PRES AND HAS
PLENTY OF CONVECTION AT THE H7 WAVE TROUGH AND ALSO ACCOMPANIED
BY SIG AMOUNTS OF MID LEVEL MOISTURE. IF WE WERE IN AUG I WOULD BE
EXCITED ABOUT POTENTIAL FOR DEVELOPMENT WITH THIS WAVE BUT IT IS
JUNE AND THE WAVE IS FORECAT TO WEAKEN AS IT MOVES TO THE
NORTHWEST AS IT MOVES INTO HIGHER SHEAR ENVIRONMENT. EXPECT THIS WAVE
WILL BRING STRONG CONVECTION TO OUR AREA SUN AS IT INTERACTS
FAVORABLY ON EAST SIDE OF TUTT FCST TO BE LOCATED OVR HISPANIOLA.
MID-UPPER LEVEL RIDGE THEN BUILDS OVR THE AREA EARLY NEXT WEEK.

.SYNOPSIS...N UPPER LEVEL TROUGH EXTENDING FROM THE SOUTHEAST
CARIBBEAN EAST NORTHEASTWARD ACROSS THE LEEWARD ISLANDS AND INTO A
DEVELOPING LOW PRESSURE CENTER ACROSS THE ATLANTIC NORTHEAST OF
PUERTO RICO IS EXPECTED TO MEANDER ACROSS THE REGION UNTIL AT LEAST
FRIDAY. THIS UPPER TROUGH WILL EVOLVE INTO AN UPPER LEVEL LOW JUST
ACROSS THE REGION BY THE UPCOMING WEEKEND. A TROPICAL WAVE ALONG 42
WEST THIS AFTERNOON WILL APPROACH TO THE REGION BY THE END OF THE
UPCOMING WEEKEND.

&&

.DISCUSSION...DOPPLER RADAR OBSERVATIONS LATE THIS MORNING AND EARLY
THIS AFTERNOON DEPICTED A LINE OF SHOWERS AND THUNDERSTORMS MOVING
SLOWLY ACROSS THE METROPOLITAN AREA AND THE NEARBY MUNICIPALITIES. A
FLOOD ADVISORY WAS ISSUED FOR SOME MUNICIPALITIES ACROSS THE
METROPOLITAN AREA BY MID MORNING. ANOTHER AREA OF SHOWERS AND
THUNDERSTORMS DEVELOPED BY MID AFTERNOON ACROSS NORTHWEST PUERTO
RICO. THIS ACTIVITY WAS THE RESULT OF DIURNAL HEATING AND LOCAL
EFFECTS IN COMBINATION WITH AN UPPER LEVEL TROUGH OVER THE REGION.
THE AFOREMENTIONED UPPER TROUGH IS EXPECTED TO MEANDER OVER THE
REGION FOR THE NEXT FEW DAYS WHILE EVOLVE INTO A LOW PRESSURE
CENTER JUST ACROSS THE LOCAL ISLANDS BY THE UPCOMING WEEKEND.
LATEST SATELLITE IMAGES THIS AFTERNOON DEPICTED A SAHARAN AIR
LAYER JUST ACROSS THE FA. HOWEVER...VISIBILITIES ACROSS THE LOCAL
FLYING AREA WAS NOT AFFECTED SO FAR. SAR IS EXPECTED TO MOVE AWAY
FROM THE REGION TONIGHT AND TOMORROW.

A TROPICAL WAVE ALONG 42 WEST THIS AFTERNOON...IS EXPECTED TO MOVE
WESTWARD DURING THE NEXT SEVERAL DAYS. THIS FEATURE IS EXPECTED TO
REACH THE LOCAL AREA BY THE END OF THE UPCOMING WEEKEND. THE GFS
MODEL GUIDANCE SUGGESTS THAT THIS WAVE WILL BECOME VERY WEAK WHEN
REACH THE LOCAL ISLANDS.

DISCUSSION FROM JUNE 05/00UTC: AT 250 HPA...A MEANDERING RIDGE IS
INITIALIZED OVER WESTERN PORTIONS OF THE DOMAIN...CENTERING ON A
CLOSED HIGH OVER THE SOUTHERN BAJA PENINSULA. THIS RIDGE IS TO
HOLD THROUGH 36-48 HRS...THEN RAPIDLY COLLAPSE BY 60-72 HRS AS A
HIGH AMPLITUDE/LONG WAVE TROUGH PATTERN ESTABLISHES ACROSS THE USA
TO NORTHERN MEXICO/THE GULF. HIGHLY AMPLIFIED/BROAD TROUGH IS TO
THEN HOLD THROUGH 96-108 HRS. FURTHERMORE...AS THE TROUGH
DEEPENS...THIS WILL DRAW A SUBTROPICAL JET MAXIMA ACROSS THE
NORTHERN STATES OF MEXICO. ITS LEFT EXIT REGION IS TO ENHANCE
DIVERGENCE ALONG THE BORDER WITH THE USA...WITH BEST DIVERGENCE
ACROSS NORTHERN COAHUILA-NUEVO LEON/SOUTHERN TEXAS EXPECTED BY
72-84 HRS. INITIALLY...UNDER INFLUENCE OF THE UPPER
RIDGE...EXPECTING DIURNAL CONVECTION TO CLUSTER ALONG THE SIERRA
MADRE OCCIDENTAL IN THE LATE AFTERNOON HOURS. BUT AS THE RIDGE
PATTERN WEAKENS...THIS IS TO ALSO DISSIPATE. OVER NORTHERN
COAHUILA/NUEVO LEON THEN EXPECT SCATTERED CONVECTION ON DAY 03 TO
SUSTAIN RAINFALL AMOUNTS OF 05-10MM/DAY AND MAXIMA OF 15-20MM/DAY.

AS THE RIDGE ALOFT MEANDERS OVER CENTRAL/NORTHERN MEXICO...IT WILL
SUSTAIN THE SOUTHWARD AMPLIFICATION OF A SHORT WAVE TROUGH ACROSS
THE EASTERN GULF TO THE YUCATAN/SOUTHERN STATES OF MEXICO. THE
TROUGH IS TO HOLD THROUGH 30-36 HRS...THEN STARTS TO PULL TO THE
NORTH-NORTHEAST AS AFOREMENTIONED LONG WAVE TROUGH PATTERN
ESTABLISHES ACROSS NORTH AMERICA. MEANWHILE...AS IT MEANDERS OVER
THE GULF...THE TROUGH ALOFT WILL INTERACT WITH A SURFACE TROUGH
BETWEEN FLORIDA AND THE SOUTHERN STATES OF MEXICO/THE YUCATAN.
THIS IS DRAWING MOISTURE/ENERGY NORTHWARD ACROSS THE YUCATAN/
WESTERN CUBA TO THE FLORIDA PENINSULA/NORTHWEST BAHAMAS. BEST
MOISTURE CONVERGENCE ACROSS WESTERN CUBA IS EXPECTED THROUGH 30-36
HRS...TO SUSTAIN RAINFALL AMOUNTS OF 25-50MM/DAY AND MAXIMA OF
75-125MM/DAY. BY 36-60 HRS THEN EXPECT RAINFALL AMOUNTS OF
10-15MM/DAY AND MAXIMA OF 20-30MM/DAY. LATER IN THE CYCLE...AS A
BROAD LOW LEVEL RIDGE BUILDS ACROSS THE BAHAMAS TO CUBA...THIS
WILL DECREASE TO 05-10MM/DAY AND MAXIMA OF 15-20MM/DAY. OTHER
ACTIVITY IS TO DEVELOP ACROSS BIMINI-GRAND BAHAMA-ANDROS
ISLAND...AS DEEP TROPICAL MOISTURE LIFTS ALONG THE FRINGES OF THE
LOW LEVEL TROUGH. IN THIS AREA EXPECTING RAINFALL AMOUNTS OF
05-10MM/DAY AND MAXIMA OF 15-25MM/DAY.

OTHER CONVECTIVE ENHANCEMENT...DUE TO THE LOW AND UPPER LEVEL
TROUGHS...IS FORECAST ACROSS THE SOUTHERN STATES OF MEXICO-YUCATAN
PENINSULA TO GUATEMALA-BELIZE. IN THIS AREA EXPECTING RAINFALL
AMOUNTS OF 10-15MM/DAY AND MAXIMA OF 20-40MM/DAY THROUGH 60 HRS.
THIS THEN DECREASES TO 05-10MM/DAY AND MAXIMA OF 15-30MM/DAY.
ACROSS SOUTHERN GUATEMALA TO CENTRAL HONDURAS/NORTHERN EL SALVADOR
EXPECT RAINFALL AMOUNTS OF 05-10MM/DAY AND MAXIMA OF 15MM.

FARTHER EAST...A CLOSED UPPER HIGH NEAR ISLA DE LA JUVENTUD
ANCHORS A RIDGE ACROSS CUBA-WESTERN CARIBBEAN/CENTRAL AMERICA TO
THE SOUTHEAST USA. UNDER PRESSURE FROM THE DIGGING UPPER TROUGH TO
THE NORTH AND WEST...THE RIDGE IS THEN FORECAST TO LIFT TO THE
NORTHEAST ACROSS CUBA/THE BAHAMAS TO THE WESTERN ATLANTIC LATER IN
THE CYCLE. AS IT EVOLVES...A MID LEVEL HIGH OVER THE BAHAMAS IS TO
THEN ANCHOR THIS AXIS. THIS IS TO STRENGTHEN THE SUBSIDENCE CAP
ACROSS EASTERN CUBA-THE CENTRAL/SOUTHEAST BAHAMAS TO PORTIONS OF
HISPANIOLA...RESULTING IN A GRADUAL DRYING TREND AND EROSION OF
PRECIPITABLE WATER CONTENT.

A TROUGH ALOFT (TUTT) FLANKS THE PERIPHERY OF THE UPPER LEVEL
RIDGE...AS IT EXTENDS TO THE SOUTHWEST ACROSS THE LEEWARD/VIRGIN
ISLES TO NORTHWEST VENEZUELA/NORTHERN COLOMBIA. AS THE RIDGE HOLDS
TO THE WEST...THIS WILL SUSTAIN INFLOW OF SHORT WAVE VORTICES THAT
ARE TO HELP SUSTAIN/REINFORCE THE TUTT PATTERN OVER THE NEXT FEW
DAYS. THE SHORT WAVE VORTICES ARE TO ALSO SPREAD SOUTHWARD ACROSS
NORTHWEST VENEZUELA INTO NORTHERN COLOMBIA. AT MID LEVELS THIS
WILL REFLECT AS A CLOSED LOW TO THE NORTH-NORTHEAST OF THE LEEWARD
ISLANDS...THAT RETROGRESSES TO THE NORTHEAST CARIBBEAN BY 54-60
HRS. ALTHOUGH A HIGHLY PERTURBED PATTERN DOMINATES THE MID/UPPER
LEVELS...AT LOW LEVELS THE DOMINANT FEATURE IS THE SUBTROPICAL
RIDGE...WITH AXIS ENVELOPING MOST OF THE ATLANTIC-CARIBBEAN BASIN.
AT 850 HPA A HIGH EAST OF BERMUDA IS TO ANCHOR THIS RIDGE. AS IT
HOLDS...THE RIDGE WILL SUSTAIN A BRISK EASTERLY FLOW ACROSS THE
ISLAND CHAIN TO THE EASTERN/CENTRAL CARIBBEAN OVER THE NEXT FEW
DAYS. THE NORTHEAST CARIBBEAN ISLES ARE TO INITIALLY LIE ON THE
CONVERGENT SIDE OF THE MID/UPPER TROUGH. BUT AS THE MID LEVEL LOW
RETROGRESSES ACROSS THE LEEWARD ISLANDS...EXPECTING SOMEWHAT MORE
FAVORABLE ENVIRONMENTAL CONDITIONS TO ESTABLISH AS IT BEGINS TO
INTERACT WITH SEA BREEZE CONVERGENCE OVER THE ISLANDS. AS A RESULT
EXPECTING SCATTERED CONVECTION ON DAY 03 TO RESULT IN RAINFALL
AMOUNTS OF 05-10MM/DAY AND MAXIMA OF 15-25MM/DAY. THIS SPREADS
ACROSS THE USVI TO EASTERN PUERTO RICO EARLY ON DAY 04.

AS THE TROUGH MEANDERS OVER NORTHERN COLOMBIA...AND INTERACTS WITH
THE NEAR EQUATORIAL TROUGH...IT IS TO ENHANCE CONVECTIVE
DEVELOPMENT. OVER NORTHERN COLOMBIA TO THE DARIEN IN PANAMA
INITIALLY EXPECT RAINFALL AMOUNTS OF 15-20MM/DAY AND MAXIMA OF
30-60MM/DAY. AFTERWARDS...EXPECTING RAINFALL AMOUNTS OF
10-15MM/DAY AND MAXIMA OF 20-45MM/DAY. ACROSS CENTRAL TO NORTHWEST
VENEZUELA EXPECTING RAINFALL AMOUNTS OF 10-15MM/DAY AND MAXIMA OF
20-35MM/DAY THROUGH 36 HRS...AND 05-10MM/DAY AND MAXIMA OF 15-20MM
THEREAFTER..

THE GUIANAS-TROPICAL ATLANTIC ARE TO REMAIN UNDER INFLUENCE OF THE
SUBEQUATORIAL RIDGE...AS IT IS TO EXTEND WEST-TO-EAST BETWEEN
60W-20W AND TO THE SOUTH OF 20N. THIS WILL VENT SEA BREEZE
CONVERGENCE ACROSS SURINAME TO FRENCH GUIANA...TO RESULT IN
RAINFALL AMOUNTS OF 05-10MM/DAY AND MAXIMA OF 15-20MM/DAY. OVER
NORTHERN GUYANA UNDER INFLUENCE OF THE ITCZ EXPECT RAINFALL
AMOUNTS OF 05-10MM/DAY AND MAXIMA OF 15-20MM/DAY. CONVECTION IS TO
SURGE OVER THE SOUTHERN WINDWARD ISLANDS LATER ON DAY 03 AS IT
INTERACTS WITH THE EASTERN CARIBBEAN TUTT.

TROPICAL/EASTERLY WAVES INITIALIZED AT 12UTC

INITIAL 24 36 48 60 72 84 TYPE

74W 77W 80W 83W 85W 87W 89W TW

THE TROPICAL WAVE ALONG 42W IS FORECAST TO AMPLIFY AS IT INTERACTS
WITH TUTT OVER THE EASTERN CARIBBEAN/LESSER ANTILLES.
THIS...IN-TURN...IS TO RESULT IN A RELATIVELY SLOW WESTWARD
PROGRESSION OF THIS PERTURBATION. THROUGH 54-60 HRS IT IS TO NEAR
FRENCH GUIANA TO RESULT IN RAINFALL AMOUNTS OF 05-10MM/DAY AND
MAXIMA OF 15-20MM/DAY. THROUGH 72-84 HRS ACTIVITY WILL SPREAD
ACROSS NORTHERN SURINAME.

TROPICAL WAVE ALONG 74W...AS IT PUSHES ACROSS COLOMBIA...IT IS TO
INTERACT WITH THE EQUATORIAL TROUGH AND A TUTT MEANDERING OVER THE
EASTERN CARIBBEAN. THIS WILL SUSTAIN A SURGE IN ACTIVITY EARLY IN
THE CYCLE WITH RAINFALL AMOUNTS OF 15-20MM/DAY AND MAXIMA OF
30-60MM. OVER JAMAICA IT IS TO FAVOR RAINFALL AMOUNTS OF
10-15MM/DAY AND MAXIMA OF 20-35MM/DAY. OVER EASTERN CUBA TO THE
CAYMAN ISLANDS EXPECTING RAINFALL AMOUNTS OF 05-10MM/DAY AND
MAXIMA OF 15MM. AS THE WAVE ENTERS EASTERN NICARAGUA/NORTHEAST
HONDURAS IT IS SUSTAIN
RAINFALL AMOUNTS OF 05-10MM/DAY AND MAXIMA OF 15-20MM/DAY.
ACROSS COSTA RICA-WESTERN PANAMA EXPECTING ACCUMULATION OF
05-10MM/DAY AND MAXIMA OF 15-20MM/DAY.

ANEGADA PASSAGE INTO THE ERN CARIBBEAN AS SEEN ON HI-RES WATER
VAPOR IMAGERY FROM MODIS TERRA AVAILABLE FROM THE NRL MRY NEXSAT
WEBSITE. THIS IN COMBINATION WITH WET SOILS AND CLEAR SKIES IS
RESULTING IN AREAS OF FOG ACROSS ERN INTERIOR AS SEEN ON HI-RES
MODIS LOW CLOUD/FOG PRODUCT AND GOES 11-3.9 MICRON IMAGERY. AS
LOCAL AREA REMAINS IN MID LEVEL SUBSIDENCE AND WEAKENING SAL AM
EXPECTING VERY LITTLE IF ANY CONVECTION THIS AFTERNOON.

UPPER LEVEL TROF AXIS THEN EVOLVES INTO A TUTT BY SAT AS IT
RELOCATES TO THE NORTH HISPANIOLA. AT THE SAME TIME...AREA OF
SOMEWHAT HIGHER TPW AIR EAST OF 60W AS SEEN ON BLENDED TPW
PRODUCT WILL INCH CLOSER TO OUR AREA SAT AND INTERACT FAVORABLY
WITH TUTT TO YIELD SCT-NMRS STRONG POSSIBLY SEVERE CONVECTION SAT
AFTERNOON. GFS 200 MB DIVERGENCE FIELDS SHOW VERY STRONG UPPER

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE SAN JUAN PR
425 AM AST SAT JUN 8 2013

.SYNOPSIS...TUTT AXIS WILL DEEPEN AS IT RELOCATES TO THE NORTH OF
HISPANIOLA. TROPICAL WAVE WILL MOVE ACROSS THE AREA SUN. A SECOND
TROPICAL WAVE WILL MOVE ACROSS THE AREA THU NIGHT AND EARLY FRI.

&&

.DISCUSSION...TUTT AXIS HAS NOW MOVED INTO THE MON PASSAGE AND AS
TUTT DEEPENS AND RETROGRESSES TOWARD HISPANIOLA LARGE SCALE ASCENT
FOR UPWARD VERTICAL MOTION WILL TAKE PLACE OVR PR LATER TODAY.
EXPECT SHOWERS AND THUNDERSTORMS TO BE EXPLOSIVE WITH THE
POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS. STRONG VERTICAL
SHEAR AND MODEST MOISTURE SHOULD LIMIT RAINFALL ACCUMULATIONS AND
RISK OF FLASH FLOODING.

NEXT IS TROPICAL WAVE APPROACHING THE ISLAND CHAIN LATER THIS
MORNING. WHILE AXIS IS EXPECTED TO MOVE ACROSS PR ON SUN...BULK OF
MOISTURE WILL REMAIN NORTH OF THE AREA WITH PR BEING ON DRY SIDE.
I WOULD EXPECT A DECREASE IN AREAL CVRG AND INTENSITY OF TSTMS
SUN. MOIST TROPICAL AIR THEN ENVELOPS THE AREA MON AND TUE WITH
WIDESPREAD CLOUDS AND NMRS CONVECTION WITH THE POTENTIAL FOR HEAVY
RAINFALL AND FLASH FLOODING ESPECIALLY TUE DUE TO ABNORMALLY HIGH
TPW AIR AND STRONG UPPER LEVEL DIVERGENCE ON EAST SIDE OF TUTT.

TUTT WILL THEN BEGIN TO FILL WED WITH DRIER AIR GRADUALLY WORKING
IN FROM THE EAST. LARGE SCALE SUBSIDENCE AND DRYING TAKES OVER THU
AHEAD OF ANOTHER TROPICAL WAVE CURRENTLY MOVING OFF OF THE AFRICAN
COAST. MODELS AGGRESSIVE WITH THIS WAVE IN TERMS OF MOISTURE
TRANSPORT AND UPPER LEVEL DIVERGENCE ALTHOUGH AM SOMEWHAT
SKEPTICAL OF IT THIS FAR OUT CONSIDERING THE AMOUNT OF DRY AIR OVR
THE TROP ATLC CURRENTLY SEEN ON CIMSS SAL PRODUCT AND PER HIGH
VALUES OF AOD OVR THE ERN ATLC SEEN ON MODIS TERRA AND AQUA FROM
YESTERDAY. THEN ANOTHER SIG SAL EPISODE WILL OVERSPREAD THE AREA
FRI NIGHT - SAT WITH STRONG WARMING AT H85 AND VERY DRY LOW TO MID
LEVEL RH`S.


.AVIATION...VFR CONDITIONS FOR ALL TAF SITES TIL ABOUT 08/16Z WHEN
SHRA/TSRA WILL DEVELOP OVER WRN PR AND MOVE WESTWARD TO BRING
MVFR/IFR CONDS AND MTN OBSCURATIONS TO/AROUND TJMZ. WINDS ARE EAST 10 TO
15 KT AND 20 KTS BTWN 0 AND 2 KFT.

&&

.MARINE...SEAS 4-6 FT AND WINDS TO 20 KT. TSTMS WILL BE MAIN HAZARD.

Does anyone has links to the islands and Central America NWS offices? It will be important to have those to gather information during the hurricane season and be posted here.
