AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
221 PM AST FRI DEC 25 2009

.SYNOPSIS...HIGH PRESSURE SYSTEM ACROSS THE CENTRAL ATLANTIC WILL
EXTEND SOUTHWESTWARD TO THE NORTHEASTERN CARIBBEAN. ANOTHER HIGH
PRESSURE SYSTEM ACROSS THE NORTHWEST ATLANTIC EXTENDS SOUTHWARD TO
JUST NORTH OF THE LOCAL AREA. THESE FEATURES WILL CREATE A LIGHT
WIND SITUATION AT THE SURFACE.

&&

.DISCUSSION...THE DOPPLER RADAR IS SHOWING A LINE OF SHOWERS AND
THUNDERSTORMS OVER THE EXTREME SOUTHEAST CARIBBEAN WATERS. LOCAL
EFFECTS AND AVAILABLE MOISTURE ARE GENERATING ISOLATED TO
SCATTERED SHOWERS ACROSS THE SOUTHERN HALF OF PORTION OF PUERTO RICO.

ALTHOUGH SATELLITES IMAGES ARE SHOWING A DRIER AIR MASS MOVING OVER
THE LOCAL FORECAST AREA ENOUGH MOISTURE WILL BE AVAILABLE TO
GENERATE ISOLATED SHOWERS ACROSS THE LOCAL FORECAST AREA. WINDS
ARE EXPECTED TO SLOWLY SHIFT TOWARD THE NORTHEAST THIS EVENING
THEREFORE EXPECTED ISOLATED TO LOCALLY SCATTERED SHOWERS TO AFFECT
THE NORTHERN PORTIONS OF PUERTO RICO. EXPECT THIS WEATHER SCENARIO
TO PREVAIL THROUGH SUNDAY.

A LARGE SWELL EVENT WILL START TO AFFECT THE NORTHERN COAST OF
PUERTO RICO INCREASING THE POTENTIAL FOR COASTAL FLOODING BETWEEN
MONDAY NIGHT AND TUESDAY.

&&

.AVIATION...EXPECT PREVAILING VFR CONDITIONS ACROSS THE LOCAL
ISLANDS AND AT ALL LOCAL TAF SITES THIS EVENING...WITH NO
SIGNIFICANT OPERATIONAL IMPACTS ANTICIPATED. 25/1200Z TJSJ SOUNDING
INDICATED A WEST NORTHWEST WIND FLOW...LIGHT UP TO 10K FEET...BUT
STRONGER ALOFT.


&&

.MARINE...A MODERATE NORTHERLY SWELL WILL BEGIN TO AFFECT THE LOCAL
WATERS LATE TONIGHT. ANOTHER PULSE WILL BE REACHING THE LOCAL
WATERS ON SUNDAY NIGHT BUT MODELS CONTINUE TO SUGGEST A LARGE NNE
SWELL REACHING OUR LOCAL WATERS ON MONDAY. THIS SWELL EVENT WILL
PEAK ON TUESDAY MORNING AT 3.6 METERS AND 16.1 SECONDS...SMALL
CRAFT AND HIGH SURF ADVISORY WILL BE ISSUE ON MONDAY.

[cycloneye]

Good morning to all.No big weather events for the next few days.


AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
311 AM AST SAT DEC 26 2009

.SYNOPSIS...AT UPPER LEVELS...A WEAK NORTHWESTERLY JET WILL CROSS
OVER THE AREA...FOLLOWED BY A BROAD HIGH PRESSURE THAT BUILDS OVER
THE CARIBBEAN EARLY IN THE WEEK. HIGH PRESSURE RETREATS VERY
SLOWLY INTO THE WESTERN CARIBBEAN THROUGH THE END OF NEXT WEEK.

AT MID LEVELS...HIGH PRESSURE REMAINS IN THE WEST CENTRAL
CARIBBEAN OVER THE WEEKEND AND THEN SLOWLY SPREADS EAST OVER NEXT
WEEK. MID LEVELS...WHICH ARE SOMEWHAT DRY...BECOME VERY DRY ON
TUESDAY AND MOISTURE DOES NOT RETURN BY THE FOLLOWING WEEKEND.

AT LOWER LEVELS...HIGH PRESSURE WILL MOVE SOUTH INTO THE CENTRAL
ATLANTIC TODAY THROUGH MONDAY. A WEAK BOUNDARY IS SAGGING SOUTH
UNDER PRESSURE FROM THIS HIGH...WITH INCREASING WINDS AND SOME MOISTURE
AND SCATTERED SHOWERS EXPECTED IN THE AREA THROUGH MONDAY.
CONDITIONS BECOME DRYER ON TUESDAY.

&&

.DISCUSSION...A FEW SHOWERS ARE MOVING SOUTH WITH A SLIGHTLY
COOLER AND MORE MOIST AIR MASS AND WILL BE THE ONLY THING HOLDING A
SIGNIFICANT POP IN THE FORECAST. SCATTERED SHOWERS WILL CONTINUE
THROUGH MONDAY AS THIS AIR MASS PLAYS THROUGH...BUT WILL BE
FOLLOWED BY A DRY SLOT THAT SHOULD CLEAR MOST RAIN AND CLOUDS FROM
THE AREA. THIS DRY AREA ROTATES AROUND WITH MOISTURE JUST BEHIND
IT...BUT THE NEXT BAND OF SIGNIFICANT MOISTURE MAY NOT BE ABLE TO
COME IN UNTIL SATURDAY OF NEXT WEEK WHEN WINDS AT 850 BECOME MORE
SOUTHEASTERLY. NOTE: SUCH FINE DETAILS ALSO MAY NOT BE RELIABLE SO
FORECAST WILL RETAIN SOME POPS THROUGHOUT. MODELS APPEAR TO
ANNOUNCE NO FRONTAL PASSAGE FOR AT LEAST NEXT 10 DAYS.

&&

.AVIATION...
MOSTLY VFR CONDITIONS ACROSS ALL LOCAL TAF SITES FOR THE NEXT 24
HOURS. SLIGHT CHANCES OF BRIEF MVFR OR IFR ARE EXPECTED ACROSS
THE LOCAL ISLANDS TODAY. WINDS WILL BE LIGHT AND VARIABLE THROUGH
MIDDAY AND THEN AFTERWARD...THERE WILL BE A MORE DEFINED EAST
NORTHEAST FLOW AT ABOUT 10 KNOTS OR SO FOR MUCH OF THE AREA FROM
THE SURFACE TO ABOUT 2-3KFT.

&&

.MARINE...SEVERAL SETS OF SWELL MOVE INTO THE AREA NOW THROUGH
TUESDAY AND SEAS AT BUOY 41043 INCREASE THROUGH TUESDAY BEFORE
DIMINISHING. THIS MAY BE THE THE LARGEST SWELL EVENT OF THE YEAR
SO FAR. WAVE WATCH FORECASTS 4 METERS...13 FEET...AT BUOY 41043
ON TUESDAY. SWELL REMAIN IN SCA STRENGTH FOR MUCH OF THE REST OF
THE WEEK THERE BUT MAY BE SLIGHTLY LESS HERE IN OUR ATLANTIC
WATERS AND PASSAGES. ROUGH SEES CONTINUE FOR QUITE A WHILE. SEAS
IN THE CARIBBEAN REMAIN RELATIVELY TRANQUIL.

Because on Christmas day the information that comes out is very slow,this morning we know here about the sad experience many residents in a town called Aibonito had as there were floodings there with the heavy rains that fell on the night of Christmas eve (Remember those warnings that I posted that night here) Only material damage with no lost of life occured.Below are some photos.

204 PM AST SAT DEC 26 2009

...HIGH SURF ADVISORY IN EFFECT UNTIL 11 AM AST WEDNESDAY...

THE NATIONAL WEATHER SERVICE IN SAN JUAN HAS ISSUED A HIGH SURF
ADVISORY...WHICH IS IN EFFECT UNTIL 11 AM AST WEDNESDAY FOR THE
NORTHWEST THROUGH NORTHEAST COASTS OF PUERTO RICO...CULEBRA AND
VIEQUES...AND FOR ST THOMAS...ST JOHN AND THE ADJACENT SMALLER
ISLANDS.

LONG PERIOD...NORTH NORTHEAST SWELLS WILL CONTINUE TO BUILD
ACROSS THE ATLANTIC WATERS AND THE CARIBBEAN PASSAGES THE REST OF
THIS AFTERNOON THROUGH SUNDAY...RESULTING IN INCREASINGLY
DANGEROUS SURF CONDITIONS ACROSS THE NORTHERN EXPOSED COASTLINES
OF MOST OF THE LOCAL ISLANDS. ALTHOUGH INITIALLY A BORDERLINE
SITUATION FOR THE REST OF THIS AFTERNOON THROUGH EARLY TONIGHT...
THESE SWELLS WILL CONTINUE TO BUILD LATER TONIGHT THROUGH
SUNDAY AND MONDAY...RESULTING IN MORE FREQUENT BREAKING WAVES OF
10 TO 15 FEET ALONG THE LOCAL REEFS...BEACHES AND SHOALS OF THE
LOCAL ISLANDS AND DANGEROUS RIP CURRENTS. THEREFORE...A HIGH SURF
ADVISORY HAS BEEN ISSUED. ALSO...THIS ADVISORY WILL PROBABLY NEED
TO BE EXPANDED TO INCLUDE ST CROIX DURING SUNDAY OR MONDAY.

HOWEVER...EVEN MORE IMPORTANTLY...NEW...VERY LARGE NORTH
NORTHEAST SWELLS OF 8 TO POTENTIALLY 11 OR 12 FEET...WITH VERY
LONG WAVE PERIODS OF 14 TO 16 SECONDS ARE EXPECTED TO INVADE THE
LOCAL WATERS BEGINNING LATE MONDAY OR MONDAY NIGHT...PEAK ON
TUESDAY AND THEN CONTINUE THROUGH AT LEAST TUESDAY NIGHT AND EARLY
WEDNESDAY. THESE SWELLS WILL LIKELY PRODUCE VERY LARGE BREAKING
WAVES OF 15 TO 22 FEET OR GREATER AND FREQUENT STRONG RIP
CURRENTS...RESULTING IN EXTREMELY DANGEROUS SURF CONDITIONS. IN
ADDITION...SIMILAR SWELL EVENTS OF THIS SIZE AND DURATION HAVE
PRODUCED SIGNIFICANT COASTAL FLOODING ALONG PARTS OF THE NORTHERN
COAST OF PUERTO RICO...AND A COASTAL FLOOD WATCH MAY ALSO BECOME
NECESSARY ON SUNDAY.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

THESE BREAKING WAVES WILL GENERATE STRONG AND DANGEROUS CURRENTS
WITHIN THE SURF ZONE...CALLED RIP CURRENTS. THESE NARROW OUTWARD
FLOWING CURRENTS CAN CARRY PEOPLE AND ANIMALS AWAY FROM THE COAST
LINE AND OUT TO SEA. IF YOU BECOME CAUGHT IN A RIP CURRENT...DO
NOT PANIC. CALMLY...REMAIN AFLOAT...GATHER YOUR BEARINGS RELATIVE
TO THE BEACH...AND SWIM PARALLEL TO THE BEACH. YOU WILL EVENTUALLY
LEAVE THE GRIP OF THIS NARROW CURRENT...AND BE ABLE TO SAFELY SWIM
TO SHORE.

LOCAL BEACH GOERS...AND INEXPERIENCED SURFERS AND SWIMMERS ARE
URGED TO STAY OUT OF THE WATER UNTIL THESE HAZARDOUS SURF
CONDITIONS SUBSIDE. PERSONS ON THE BEACH SHOULD BE VIGILANT FOR
LARGE BREAKING WAVES SURGING UPON THE SHORE...WHICH CAN CARRY
PEOPLE OF ALL SIZES INTO THE OCEAN. YOU SHOULD AVOID BEING NEAR
THE SHORE LINE AND STAY OFF OF ROCK FORMATIONS.

THESE SURGING WAVES WILL ALSO CREATE THE POTENTIAL FOR BEACH
EROSION DURING TIMES OF HIGH TIDE.

THE TIMES AND HEIGHTS OF THE NEXT HIGH TIDES FOR THE FOLLOWING
LOCATIONS ARE:

SAN JUAN HARBOR: 1.0 FEET AT 3:09 PM AST THIS AFTERNOON
1.5 FEET AT 5:21 AM AST SUNDAY

It looks like a more wetter next couple of days for the NE Caribbean and that is apart from the high surf advisory that is up so lets see what will occur.Interesting updated discussion tonight about all aspects of the weather expected and the high surf.

855 PM AST SAT DEC 26 2009

.UPDATE...WHILE SHOWERS HOLD ON OVER SOUTHWEST PUERTO
RICO...PERHAPS ANOTHER HOUR OR SO...THE BOUNDARY BEARING SHOWERS
AND STRONGER EAST WINDS DEFIES ALL MODEL PREDICTIONS BRINGING IT
SOUTH...DOWN OVER PUERTO RICO TONIGHT. IT IS UNCLEAR THAT IT WILL
COME SOUTH TOMORROW MORNING EITHER BUT WITH INCREASING HIGH
PRESSURE TO THE NORTH IT SEEMS LIKE IT SHOULD COME DOWN SOMETIME.
IN ANY EVENT...WITH OR WITHOUT THIS BOUNDARY...NOW POISED JUST NORTH
OF 19.5 DEGREES NORTH LATITUDE...SHOWERS SEEM LIKELY TO DEVELOP
OVER THE INTERIOR OF PUERTO RICO AND PERHAPS ALONG THE CHAIN OF
THE LESSER ANTILLES INCLUDING THE NORTHERN VIRGIN ISLANDS SUNDAY
AFTERNOON AS MOIST AIR BECOMES UNSTABLE WITH DAYTIME HEATING. THUS
HAVE LOWERED POPS OVER PUERTO RICO`S NORTHERN COAST TONIGHT AND
DELAYED THE ARRIVAL OF THE BAND OF SHOWERS EXPECTED LATE TONIGHT
INTO TOMORROW MORNING AFTER 6 AM AST. BUT HAVE RAISED POPS TO
NUMEROUS OVER CENTRAL PUERTO RICO SUNDAY AFTERNOON. OTHER CHANGES
INCLUDE MINOR TWEAKS THROUGHOUT...BUT LITTLE IS EXPECTED IN THE
WAY OF SIGNIFICANT WEATHER NEXT WEEK...AND...IF THE MODELS CAN BE
BELIEVED 240 HOURS OUT...TUESDAY 5 JAN 2010...EVEN A LATE FRONT
WILL STALL NORTHWEST JUST SHORT OF THE LOCAL FORECAST AREA...BUT
IT WILL BE CLOSE.

&&

.DISCUSSION...SOUNDING HAD VERY LIGHT WINDS AGAIN TONIGHT IN THE
LOWER LEVELS WITH NOTHING ABOVE 10 KNOTS BELOW 12 THOUSAND FEET.
ABOVE WHICH WINDS WERE UNCHARACTERISTICALLY NORTH FROM 15 TO 55
KNOTS...THE 55 KNOTS...OF COURSE...BEING ABOVE 300 MB. THESE NORTHERLY
WINDS REFLECT THE PRESENCE OF HIGH PRESSURE OVER THE WESTERN
CARIBBEAN. THIS WILL CHANGE LITTLE IN THE NEXT 150 HOURS AND IS ONE
OF THE MAIN REASONS WEATHER WILL TEND TOWARD CLEMENCY. THE MIMIC
PRODUCT DID SHOW A NORTH-SOUTH BAND OF HIGHER PRECIPITABLE WATER
TO THE EAST MOVING VERY SLOWLY TOWARD THE AREA AND THIS MAY
INCREASE THE SHOWER ACTIVITY BEFORE THE DRIER AIR ARRIVES FROM THE
NORTHEAST ON TUESDAY.

NOTHING NEW TO ADD REGARDING HIGH SURF ADVISORY. SWELL AT BUOY
41043 FROM THE NORTH NORTHEAST HAVE LEVELED OFF AT AROUND 6 FEET
EVERY 10 SECONDS AWAITING THE NEXT SHORT PULSE OF 8 TO 9 FOOT
EVERY 12 SECONDS SWELL TONIGHT AND THEN A GRADUAL INCREASE SUNDAY
THROUGH TUESDAY UNTIL SWELL REACH 12 FEET EVERY 14 SECONDS. SURF
WILL BE UP.

&&

.AVIATION...
PREVAILING VFR CONDITIONS ARE EXPECTED ACROSS ALL THE LOCAL TAF
SITES THROUGH 27/06Z. AFTERWARD...EXPECT BRIEF MVFR CIGS ACROSS
TIST...TNCM...TJBQ AND TJSJ FROM 27/08-27/14...AS THE REMNANTS OF
AN OLD FRONTAL BOUNDARY TO THE NORTH SINK SOUTHWARD. DUE TO THE
PROXIMITY OF THIS BOUNDARY ON SUNDAY...EXPECT THE POSSIBILITY OF
TEMPORARY MVFR CIGS ACROSS ALL THE TAF SITES AFT 27/14Z...WITH
PREVAILING VFR CONDITIONS.

IT HAS REACHED PUERTO RICO AND MAY DRIFT SOUTH OF THE U.S. VIRGIN
ISLANDS MONDAY.


&&

.DISCUSSION...SHOWERS CONTINUE TO REMAIN ACTIVE OVER THE LOCAL
WATERS EVEN THOUGH ALL SHOWERS HAVE DISSIPATED FROM THE LOCAL LAND
MASSES. ALTHOUGH NOT MANY SHOWERS WILL BE NOTED OVER THE WINDWARD
COASTS OF THE LOCAL ISLANDS...MODELS INSIST THAT THERE WILL BE
CONSIDERABLE SHOWER ACTIVITY THIS AFTERNOON IN SOUTH CENTRAL
PUERTO RICO WHICH WILL EXTEND TO THE WESTERN COAST OF THE ISLAND
BY MID AFTERNOON. ANOTHER BATCH OF SHOWERS MOVES ONSHORE IN
NORTHEAST PUERTO RICO ON MONDAY MORNING. SHOWERS WILL DIMINISH

TEMPORARY MVFR CIGS ACROSS MOST OF THE TAF SITES AFT 27/16Z TO
27/22Z...WITH PREVAILING VFR CONDITIONS. LIGHT TO GENTLE EAST TO EAST
NORTHEASTERLY WINDS TO PREVAIL ACROSS THE LOCAL AREA FOR THE NEXT 12
TO 18 HOURS.

&&

.MARINE...SEAS AND AN ANOMALOUSLY HIGH BATCH OF SWELL FROM VERY STRONG
LOWS IN THE ATLANTIC WILL KEEP CONDITIONS IN THE ATLANTIC AND TO A
LESSER EXTENT THE CARIBBEAN SOUTH OF LOCAL PASSAGES...ROUGH AND GENERALLY UNSAFE FOR
TRAVEL OR RECREATION THROUGH THURSDAY. SWELL APPEARS TO PEAK ON WEDNESDAY.

Wow! What is causing this? Keep us posted on any damage etc. How about our friends on Vieques ,Culebra, St. John, St. thomas etc? Any reports form there?

Its caused by that very strong low in the NE Atlantic.Yes,I want our friends in the islands to report what is going on in those exposed coasts of the islands.

[vbhoutex]

That must be a very strong storm. And with nothing betweeen it ans the islands the fetch would produce large waves.

[cycloneye]

Coastal Flood Watch is up,High Surf Advisory timeframe extends to 6 PM on Wednesday

Lets be careful in the coastal zones and not venture into the water as rip currents are very dangerous.Those surfers that dont have sufficient experience also dont go out there.

Wow! What is causing this? Keep us posted on any damage etc. How about our friends on Vieques ,Culebra, St. John, St. thomas etc? Any reports form there?

The real peak of the highest waves will arrive by Monday and last until tuesday so the worse is yet to come.I really hope that no bad news occurs from this because is very dangerous to be on a beach inside the water as the rip currents are strong.News came late this afternoon that a group of six tourists were in a beach and one of them fell from a rock and was carried away briefly but he was thankfully rescued.I will be reporting any news concerning this from Puerto Rico.I am also eagered to see reports from our friends in the rest of the islands.

Its caused by that very strong low in the NE Atlantic.Yes,I want our friends in the islands to report what is going on in those exposed coasts of the islands.

Yellow alert has been requiered by Meteo-France for Guadeloupe (Leewards)and the Northern Leewards (St Marteen and St Barth)... For your info the latest data of Meteo-France is indicating that waves have reached 3 meters tonight near Guadeloupe and should be up to 4 meters tommorow night and could intensify a little more, maybe close to 4/5 meters or even huge waves close to 6 meters ? . Something to keep an eye on, let's wait and see but here is the latest from Guadeloupe my carib friends.
