Good morning to all.In general,good weather for the NE Caribbean today.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
449 AM AST TUE FEB 2 2010

.SYNOPSIS...A MODERATE TO FRESH TRADE WIND WILL PREVAIL ACROSS THE
REGION FOR THE NEXT SEVERAL DAYS. SUBTROPICAL RIDGE WILL HOLD
STRONG THROUGH THE END OF THE WEEK.

&&

.DISCUSSION...A CLUSTER OF CLOUD AND ISOLATED SHOWERS MOVED ACROSS
THE LOCAL FORECAST AREA THROUGH THE OVERNIGHT HOURS. THE DOPPLER
RADAR IS SHOWING AFE SHOWERS MOVING ACROSS THE EASTERN PORTION OF
PUERTO RICO. THIS CLUSTER IT IS EXPECTED TO MOVE TOWARD THE WEST
THROUGH THE EARLY MORNING HOURS AND AWAY FROM THE AREA AT AROUND
SUNRISE. SATELLITES IMAGES ARE SHOWING AN AREA OF CLEAR SKIES AND
LIMITED SHOWERS JUST TO THE EAST OF PUERTO RICO...BUT ANOTHER
CLUSTER OF SHOWERS AND CLOUD IS EXPECTED TO REACH ONCE AGAIN OUR
LOCAL FORECAST AREA BEFORE NOON. THIS WILL GENERATE ISOLATED TO
LOCALLY SCATTERED SHOWERS ACROSS THE EASTERN PORTIONS OF PUERTO RICO.

SOUTHEAST WINDS WILL PRODUCE HIGHER TEMPERATURES TODAY MAINLY
ACROSS THE NORTHERN PORTIONS OF THE ISLAND OF PUERTO RICO. A
SIMILAR WEATHER SCENE ARIO SHOULD CONTINUE THROUGH THE INCOMING
WEEKEND.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED AT ALL TAF SITES NEXT 24
HOURS. WINDS AGAIN TO BE IN THE 15 TO 20 KT FROM FROM THE ESE AT
TJSJ...TIST...TISX AND TJBQ. VA FROM MONTSERRAT NOW LIKELY BEING
TRANSPORTED TOWARDS TO THE GENERAL VICINITY OF TISX...BUT TO DIFFUSE
AND TO FAR TO THE EAST TO BE A CONCERN AT THIS TIME.

&&

.MARINE...NEITHER THE BUOY 41043 TO THE NORTH OR THE BUOY 42060 TO
THE SOUTHEAST ARE SHOWING SEAS OF ABOVE 7 FEET...THEREFORE
CANCELLED THE SMALL CRAFT ADVISORIES FOR ALL LOCAL WATERS WITH
THE EXCEPTION OF THE LOCAL OFF SHORE ATLANTIC WATERS. MARINERS ARE
URGED TO EXERCISE CAUTION ACROSS THE REST OF THE LOCAL WATERS.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
310 PM AST TUE FEB 2 2010

.SYNOPSIS...FAIRLY TIGHT PRES GRADIENT BETWEEN THE CENTRAL ATLANTIC
HIGH PRESSURE AND BROAD SURFACE LOW PRESSURE TROUGH ACROSS THE
EASTERN CARIBBEAN CONTINUED TO PRODUCE MODERATE TO STRONG EAST
SOUTHEAST TRADES ACROSS THE LOCAL REGION. THIS GENERAL PATTERN WILL
CONTINUE FOR THE NEXT 24 HOURS OR SO...WITH THE SURFACE PRESSURE
GRADIENT EXPECTED TO RELAX ACROSS THE AREA DURING THE LATTER PART OF
THE WEEK...AS THE ATLANTIC HIGH RECEDES FURTHER EAST AND A LOW
PRESSURE SYSTEM AND ASSOCIATED COLD FRONT MOVES ACROSS THE WESTERN
ATLANTIC. MID TO UPPER LEVEL SHORT WAVE TROUGH EXTENDING ACROSS THE
SOUTHWEST ATLANTIC INTO THE SOUTH CENTRAL CARIBBEAN WILL LIFT
NORTHEAST ACROSS THE REGION AIDED BY 60-70 KNOTS SUBTROPICAL JET
SEGMENT TODAY THROUGH WEDNESDAY.

&&

.DISCUSSION...
GENERAL EAST SOUTHEAST LOW LEVEL WIND FLOW WILL CONTINUE TO BRING
PATCHES OF MOISTURE ACROSS THE REGION FOR NEXT 24 HOURS OR SO. LOCAL
AND DIURNAL INFLUENCES... AND SOMEWHAT FAVORABLE CONDITIONS IN THE
MID TO UPPER LEVEL MAY HELP PRODUCE BRIEF ISOLATED LATE AFTERNOON
CONVECTION ACROSS PARTS OF PUERTO RICO...BUT NO SIGNIFICANT
RAINFALL EXPECTED TODAY DUE TO LACK OF WIDESPREAD MOISTURE. IN
ADDITION...THE VEERING SOUTHERLY WINDS AND INJECTION OF DRIER AIR
IN THE LOW TO MID LEVELS WILL LIMIT SHOWER DEVELOPMENT TODAY.

A MORE STABLE AND DRIER WEATHER PATTERN EXPECTED AFTER WEDNESDAY AND
THE REST OF WEEK...AS MID TO UPPER LEVEL RIDGE BUILDS ACROSS REGION
AND LOW LEVEL WIND FLOW SLOWLY BECOMES MORE EASTERLY BRINGING EVEN
DRIER AND MORE STABLE CONDITIONS ACROSS THE AREA. LOW LEVEL WIND
WILL ALSO CONTINUE TO DECREASE OVER AREA TODAY AND THE REST OF THE
WEEK...AS THE PRESSURE GRADIENT WEAKENS. THIS WILL ALLOW FOR BETTER
CHANCE FOR MOSTLY ISOLATED AFTERNOON LOCAL AND SEA BREEZE INDUCED
CONVECTION ACROSS PARTS OF THE ISLANDS.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED TO PREVAIL AT ALL TAF SITES
THROUGH 03/22Z. SURFACE AND LOW LEVEL FLOW WILL CONTINUE FROM THE
EAST SOUTHEAST. THIS WILL BRING VOLCANIC ASH INTO THE AREA THAT MAY
AFFECT TIST...TISX...TJPS...TJSJ AND POSSIBLY TJBQ WITH VERY DIFFUSE
ASH...DEPENDING ON EMISSIONS FROM THE VOLCANO ON MONTSERRAT. PILOTS
SHOULD MONITOR SIGNETS AND SATELLITE IMAGERY FOR LATEST INFORMATION.
SIGMET BRAVO 6 WILL BE IN EFFECT UNTIL 02/2030Z.

.UPDATE...FAIR WEATHER IS FORECAST DURING THE NEXT DAY OR SO. MID TO
UPPER LEVEL RIDGE WILL CONTINUE DOMINATING THE LOCAL AREA AT LEAST
NEXT 48 HOURS WITH SHOWER ACTIVITY...IF ANY...DURING THE MORNING
HOURS ACROSS THE EASTERN HALF OF PUERTO RICO...AND IN THE WESTERN
PART AND MOUNTAIN SECTIONS OF PUERTO RICO DUE TO SEA BREEZE
INDUCED CONVECTION. THEREFORE...FORECAST UNCHANGED FROM AFTERNOON
PACKAGE.

&&

.AVIATION...VFR CONDITIONS NEXT 24 HRS AT ALL TAF SITES. WINDS
WILL REMAIN OUT OF THE SOUTHEAST AROUND 10 KTS NEXT 24 HRS. LAST
VIS IMAGES BEFORE SUNSET SHOWED SOME VOLCANIC ASH ABOUT 40 NM TO
THE SOUTHEAST OF ST. CROIX MOVING NW SO HAVE INCLUDED VA IN FOR
THEM. GIVEN STEERING WINDS FROM THE SOUTHEAST ANY ADDITIONAL
EMISSIONS WOULD STEER ANY ASH TOWARD ST. CROIX. VA MAY REACH PR
LATE TOMORROW AFTERNOON.

Good Morning to all.Warmer than usual for this time of year.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
510 AM AST WED FEB 3 2010

.SYNOPSIS...A MID TO UPPER LEVEL RIDGE WILL BE THE DOMINANT
WEATHER FEATURE LOCALLY FOR THE NEXT FEW DAYS.

&&

.DISCUSSION...EXPECT GENERALLY FAIR AND MAINLY DRY WEATHER ACROSS
THE LOCAL ISLANDS FOR THE NEXT FEW DAYS...AS AFOREMENTIONED MID TO
UPPER LEVEL RIDGE AND ASSOCIATED SUBSIDENCE KEEP SHOWER ACTIVITY
LIMITED. THAT SAID...AS IS TYPICAL FOR THIS TIME OF YEAR...WE WILL
CONTINUE TO HAVE PATCHES AND BANDS OF MOISTURE MOVING ACROSS THE
LOCAL AREA FROM TIME TO TIME RESULTING IN INTERVALS OF CLOUDINESS
AND A FEW SHOWERS. FOR TODAY...MAINLY SOUTHEAST WINDS AND ABUNDANT
SUNSHINE SHOULD ALLOW FOR UNSEASONABLY WARM AND NEAR RECORD HIGH
TEMPERATURES ALONG THE NORTH COASTAL SECTIONS OF PUERTO RICO.
PLEASE REFER TO THE CLIMATE SECTION BELOW FOR MORE DETAILS.

&&

.AVIATION...PREVAILING VFR CONDITIONS EXPECTED ACROSS ALL TAF
SITES FOR THE NEXT 24 HRS...WITH A VCSH OR BRIEF MVFR CIG
POSSIBLE ACROSS TJMZ AND TJBQ AFT 03/17Z. WINDS WILL REMAIN OUT OF
THE SOUTHEAST AROUND 10-15 KTS NEXT 24 HRS...WHICH WILL RESULT IN
VA LIKELY AFFECTING TISX...AND POSSIBLY EVEN SPREADING ACROSS
TIST AND TJSJ AFT 03/16Z. WILL NEED TO MONITOR AS SUN COMES UP AS
VA IS NO LONGER CLEARLY IDENTIFIABLE IN SATELLITE IMAGERY AND NO
HOT SPOTS NOTED LAST FEW HOURS.

&&

.MARINE...EXPECT WINDS OF 18 KNOTS OR LESS AND SEAS OF 7 FEET OR
LESS ACROSS THE REGIONAL WATERS THROUGH FRIDAY...HIGHEST TODAY
AND TONIGHT. A SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR THE
ATLANTIC OFF SHORE WATERS TODAY AND SMALL BOAT OPERATORS SHOULD
EXERCISE CAUTION ACROSS MOST OF THE REMAINING ATLANTIC AND
CARIBBEAN COASTAL WATERS.

&&

.CLIMATE...SOUTHEAST FLOW AND ABUNDANT SUNSHINE WILL RESULT IN
UNSEASONABLY WARM TEMPERATURES ACROSS THE NORTHERN HALF OF PUERTO
RICO TODAY. THE FORECAST HIGH TEMPERATURE OF 87 FOR TODAY WOULD
TIE THE PREVIOUS RECORD HIGH TEMPERATURE OF 87...REACHED JUST THIS
PAST YEAR. RECORD KEEPING AT THE LUIS MUNOZ MARIN AIRPORT BEGAN
BACK IN 1956.

[Macrocane]

Good morning! Here in El Salvador February is the driest month, in San Salvador the average precipitation for this month is only 2mm (0.08 inches). The average low temperature is 17 °C (62.6 °F) and the average high is 32 °C (89.6 °F). Since the third week of January above average temperatures have been present in the country because of the lack of strong cold fronts and this week has been the warmest with the hottest day being yesterday, the low temperature yesterday was 19.6 °C (67.3 °F) and the high 33 °C (91.4 °F) those temps are more likely to occur in March or April wich are the warmest months of the year, but february is still part of the cool season and shouldn't be that warm. The city of San Miguel (the warmest place of El Salvador) registered yesterday a low of 19.8 °C (67.6 °F) and the high was 39.7 °C (103.5 °F) the average for this month in that city are 18 °C (64.4 °F) and 37 °C (98.6 °C) respectively. A rather strong cold front may reach the area next week bringing a relief to the country but until then we will have temperatures of late March and April.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
303 PM AST WED FEB 3 2010

.SYNOPSIS...AT UPPER LEVELS...PASSING MID LATITUDE TROUGHS CAUSE
UNDULATIONS BUT LITTLE DISPLACEMENT IN THE HIGH PRESSURE OVER
NORTHERN SOUTH AMERICA THAT EXTENDS INTO THE CARIBBEAN. A WEAK JET
IS OVER THE LOCAL AREA UNTIL FRIDAY AND DOES NOT RETURN UNTIL NEXT
WEDNESDAY.

AT MID LEVELS...HIGH PRESSURE MOVES BACK AND FORTH BETWEEN THE
CENTRAL AND EASTERN CARIBBEAN AND THE TROPICAL ATLANTIC. THE MID
LEVEL ATMOSPHERE REMAINS VERY DRY.

AT LOWER LEVELS...A WEAK TROUGH AIDED BY A PASSING SHORT WAVE TO
THE NORTH...APPROACHES THE LOCAL AREA BUT REMAINS NORTH. MODELS DO
NOT SHOW ANOTHER FRONTAL BOUNDARY CROSSING THROUGH THE AREA UNTIL
THE FRIDAY AFTER NEXT. IN THE MEANTIME PATCHES OF SHALLOW MOISTURE
MOVE THROUGH THE AREA.


&&

.DISCUSSION...A FEW VERY SMALL SHOWERS FORMED DURING THE AFTERNOON
UP TO 3 PM...BUT OTHERWISE THERE WAS VERY LITTLE SHOWER ACTIVITY
AND PARTLY SUNNY SKIES ACROSS MOST OF THE AREA. WINDS OVER THE
FORECAST AREA WERE STILL EAST SOUTHEAST TO SOUTHEAST AND THIS DID
BRING DIFFUSE ASH FROM THE MONTSERRAT VOLCANO OVER SAINT CROIX AND
POSSIBLY CULEBRA...VIEQUES AND EASTERN PUERTO RICO. WINDS SHOULD
SHIFT ENOUGH TO THE EAST NORTHEAST SO THAT THIS ENDS THURSDAY OR
EARLY FRIDAY. OTHERWISE SPARSE MOISTURE TRAPPED UNDER A STRONG
INVERSION WILL PRODUCE A FEW CLOUDS AND BRIEF...ISOLATED...PASSING
SHOWERS IN A PREDOMINANTLY DRY REGIME. EVEN THE FRONTAL PASSAGE
FORECAST BY THE GFS TO ARRIVE BY FRIDAY...12 FEBRUARY...HAS BEEN
DELAYED BY 24 HOURS FROM YESTERDAYS RUNS AND NO LONGER PRESENTS A
MONOLITHIC BAND OF MOISTURE WHEN IT PASSES...BUT RATHER IS
FRAGMENTED INTO PATCHES THAT MAY OR MAY NOT VERIFY WHEN HOUR 216
ROLLS AROUND.


&&

.AVIATION...
PREVAILING VFR CONDITIONS EXPECTED ACROSS ALL TAF SITES
FOR THE NEXT 24 HRS. BRIEF PERIODS OF MVFR CONDITIONS ARE POSSIBLE
ACROSS TJMZ AND TJBQ WITH MOUNTAIN OBSCURATIONS AT LEAST THROUGH
03/22Z. VA WILL BE AFFECTING TISX THROUGH AT LEAST 03/22Z...AND TKPK
THROUGH AT LEAST 04/09Z.


&&

.MARINE...VIGOROUS LOWS WILL TRAVERSE THE ATLANTIC OCEAN NORTH OF
THE AREA...ONE OF WHICH IS FORECAST TO DEEPEN TO 940 MB ON
FRIDAY. HOWEVER THE 40 - 50 PLUS KNOT WINDS IN THIS LOW HAVE A
VERY NARROW SWATH AND WILL BE POINTING OUR WAY ONLY BRIEFLY. WHILE
THIS WON`T BE ENOUGH TO BRING VERY HIGH SEAS TO THE AREA...IT WILL
KEEP SEVERAL SWELL TRAINS HEADED OUR WAY AND SEAS WILL VARY FROM 3
TO 7 FEET DURING THE NEXT 10 DAYS. CARIBBEAN SEAS WILL GENERALLY
FARE BETTER WITH NO SMALL CRAFT ADVISORIES ANTICIPATED FOR AT
LEAST THE NEXT 5 TO 7 DAYS.

.SYNOPSIS...A MID TO UPPER LEVEL RIDGE WILL REMAIN THE DOMINANT
WEATHER FEATURE LOCALLY FOR THE NEXT FEW DAYS.

&&

.DISCUSSION...STILL EXPECT GENERALLY FAIR AND MAINLY DRY WEATHER
ACROSS THE LOCAL ISLANDS FOR THE NEXT FEW DAYS...AS AFOREMENTIONED
MID TO UPPER LEVEL RIDGE AND ASSOCIATED SUBSIDENCE KEEP SHOWER
ACTIVITY LIMITED. HOWEVER...WE WILL CONTINUE TO HAVE PATCHES AND
BANDS OF MOISTURE MOVING ACROSS THE LOCAL AREA FROM TIME TO TIME
RESULTING IN INTERVALS OF CLOUDINESS AND A FEW SHOWERS. IN
ADDITION...WEAK...INVERTED LOW LEVEL TROUGH MOVING ACROSS THE
LOCAL AREA AT THIS TIME AND COULD ENHANCE SHOWER ACTIVITY SLIGHTLY
TODAY...BUT DO NOT EXPECT ANY PROBLEMS FROM IT.

&&

.AVIATION...PREVAILING VFR CONDITIONS EXPECTED ACROSS ALL TAF
SITES FOR THE NEXT 24 HRS. VERY LIMITED SHOWER ACTIVITY EXPECTED
AND WINDS WILL BECOME EASTERLY AROUND 10 KTS...WITH LOCAL SEA
BREEZE INFLUENCED VARIATIONS. THE MORE EASTERLY SYNOPTIC WIND FLOW
SHOULD KEEP VA FROM MONTSERRAT SOUTH OF ALL LOCAL TAF SITES AFT
04/14Z.

LESS ACROSS THE REGIONAL WATERS THROUGH SATURDAY. THE SMALL CRAFT
ADVISORY FOR THE ATLANTIC OFF SHORE WATERS HAS BEEN CANCELLED.

Afternoon discussion by NWS San Juan

Beautiful weather for the next few days as no big weather features are forecast to move thru the NE Caribbean so those who like warm weather and live in the U.S. Mainland,why you dont come to the warm Caribbean to pass a vacation?


AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
302 PM AST THU FEB 4 2010

.SYNOPSIS...AT UPPER LEVELS...RIDGING OVER THE CENTRAL CARIBBEAN WILL
DRIFT EAST OVER THE LOCAL AREA AND INTO THE TROPICAL ATLANTIC ON
SATURDAY AND SATURDAY NIGHT. RIDGING WILL RETURN TO THE CENTRAL
AND WESTERN CARIBBEAN MID WEEK NEXT WEEK.

AT MID LEVELS...HIGH PRESSURE FOLLOWS MUCH THE SAME PATTERN AS AT
UPPER LEVELS. THE GFS SHOWS A BROAD AND DEEP MID LATITUDE TROUGH
PASSING TO THE NORTH SATURDAY 13 FEB. MID LAYER MODEL MOISTURE
REMAINS BELOW 15 PERCENT UNTIL THEN AND DOES NOT REACH 50 PERCENT
AT ANY TIME.

AT LOWER LEVELS...SHALLOW MOISTURE IN POORLY DEFINED PATCHES WILL
PASS THROUGH THE LOCAL AREA OCCASIONALLY SPAWNING LIGHT SHOWERS ON
THE WINDWARD COASTS. A FEW SMALL SHOWERS WILL ALSO OCCUR OVER
INLAND PUERTO RICO DURING THE AFTERNOONS IN CONVERGENT FLOW AND
DOWNSTREAM OF THE U.S. VIRGIN ISLANDS. FOR NOW...THE WEEKEND APPEARS
TO BE THE DRIEST PERIOD.

&&

.DISCUSSION...HIGH PRESSURE DOMINATES THE AREA WITH SHALLOW
MOISTURE AND STRONG CAPPING BETWEEN 5 AND 10 THOUSAND FEET. LITTLE
CHANGE IS EXPECTED THIS WEEK AND MOST OF NEXT. AN OLD AND VERY
WEAK FRONTAL BOUNDARY SITS NOT TOO FAR NORTH OF THE AREA AS A
VERY STRONG LOW PRESSURE DEEPENS VERY RAPIDLY IN THE WESTERN
ATLANTIC WHILE MOVING NORTHEAST. THE FRONT IS NOT EXPECTED TO PASS
THROUGH THE AREA...THIS WILL HAVE TO WAIT UNTIL THE SATURDAY AFTER
NEXT...HOWEVER THE TRAILING TROUGH IS HAVING THE EFFECT OF CALMING
WINDS AND WEAKENING TRADE WIND FLOW. THIS WILL SHIFT BRIEFLY TO THE
EAST NORTHEAST ON FRIDAY...BUT BACK TO THE SOUTHEAST...POSSIBLY
EVEN TO THE SOUTH OVER THE WEEKEND. THE SHIFT TO SOUTHERLY FLOW WILL
BRING DRIER WEATHER OVERALL BUT ESPECIALLY ON THE NORTH COAST.
ALSO EXPECT WARMER TEMPERATURES ON THE NORTH COAST. NEVERTHELESS
SINCE MAXIMUM TEMPERATURE RECORDS FOR 5-13 FEB RANGE FROM 90 TO 93
DEGREES...NEW RECORDS MAY BE HARD TO ESTABLISH. DRIER WEATHER IS
EXPECTED TO CONTINUE AT LEAST THROUGH THE FRIDAY AFTER NEXT OR 12
FEB.

&&

.AVIATION...
PREVAILING VFR CONDITIONS EXPECTED ACROSS ALL TAF SITES
FOR THE NEXT 24 HRS. VERY LIMITED SHOWER ACTIVITY EXPECTED THROUGH
FRIDAY AFTERNOON. VOLCANIC ASH FROM MONTSERRAT IS NOT EXPECTED
DURING THE NEXT 48 TO 60 HOURS.

&&

.MARINE...CONDITIONS WILL BE QUIESCENT WITH WEAKER WINDS AND LESS
SWELL. ON SATURDAY A SHORT WAVE TRAIN ARRIVES FROM A STRONG
ATLANTIC LOW THAT MODELS STILL FORECAST TO ACHIEVE 940 MB ON 05/18Z.
THESE WAVES WILL DIE QUICKLY BUT SHOULD THROW THE ATLANTIC WATERS
BACK UNDER A SMALL CRAFT ADVISORY. ANOTHER WAVE TRAIN OF SIMILAR
INTENSITY IS EXPECTED ON TUESDAY.

.DISCUSSION...ALTHOUGH CLOUDS HAVE DEVELOPED ALONG THE CORDILLERA
CENTRAL...THE RADAR IS ONLY SHOWING A FEW VERY ISOLATED SHOWERS
ACROSS THE INTERIOR SECTIONS OF PUERTO RICO.

A STABLE AND MAINLY DRY WEATHER PATTERN IS STILL EXPECTED TO CONTINUE

525 AM AST SAT FEB 6 2010

.SYNOPSIS...HIGH PRESSURE AND LIMITED LOW LEVEL MOISTURE WILL HELP
TO KEEP SHOWER ACTIVITY TO A MINIMUM ACROSS THE LOCAL ISLANDS
FOR THE NEXT SEVERAL DAYS.

&&

.DISCUSSION...NICE WEATHER EXPECTED ACROSS THE LOCAL ISLANDS
THROUGH THE REMAINDER OF THE WEEKEND INTO EARLY NEXT WEEK AS HIGH
PRESSURE IN THE MID TO UPPER LEVELS OF THE ATMOSPHERE WILL HELP TO
INHIBIT ANY WIDESPREAD OR SIGNIFICANT SHOWER ACTIVITY. THIS RIDGE
OF HIGH PRESSURE IS EXPECTED TO WEAKEN AND FLATTEN OUT EARLY NEXT
WEEK...WHICH IN COMBINATION WITH A SURGE IN MOISTURE FROM THE SOUTHEAST
AND A FRONTAL BOUNDARY TO OUR NORTH...WILL LIKELY RESULT IN AT
LEAST A FEW MORE SHOWERS TUESDAY THROUGH FRIDAY. HOWEVER...THE
FRONTAL BOUNDARY ITSELF IS FORECAST TO REMAIN NORTH OF THE LOCAL

.SYNOPSIS...AT UPPER LEVELS...HIGH PRESSURE DOMINATES THE
CARIBBEAN WITH A SUB TROPICAL JET UNDULATING NORTH OF THE FORECAST
AREA WITH THE PASSING OF MID-LATITUDE TROUGHS.

AT MID LEVELS...HIGH PRESSURE WILL DOMINATE THE CARIBBEAN. SOME
TROUGHINESS WILL CREEP INTO THE WESTERN END OF THE CARIBBEAN MID-
MONTH. THE MID LEVELS OVER PUERTO RICO AND THE U.S. VIRGIN ISLANDS
REMAIN DRY.

AT LOWER LEVELS...AN OLD AND WEAK BOUNDARY WILL RETREAT TO THE
NORTHEAST AS A SECOND FRONT MOVES THROUGH CUBA AND TOWARD THE
LOCAL AREA. THE TRAILING END OF THIS FRONT WILL DISSIPATE NORTH OF
20 DEGREES NORTH DURING THE MIDDLE OF THE WEEK. A THIRD FRONT IS
CURRENTLY EXPECTED TO PASS THROUGH THE AREA ON FRIDAY OR SATURDAY
OF NEXT WEEK. CONDITIONS ARE MOSTLY DRY DURING THE PERIOD.


&&

.DISCUSSION...EVEN FEWER SHOWERS APPEARED OVER THE AREA TODAY THAN
YESTERDAY. THE LOWER LEVELS OF THE ATMOSPHERE REMAIN CAPPED AND
LOWER LEVEL FLOW WAS TURNING TO THE SOUTHEAST. A BOUNDARY TO THE
NORTH WILL RETREAT DURING THE NEXT 48 HOURS...WHILE ANOTHER MOVES
TOWARD THE AREA. FLOW WILL REMAIN GENERALLY LIGHT AND WITH A
SOUTHERLY COMPONENT AND MOISTURE WILL BE SCARCE. EXPECT THE DRY
TREND TO CONTINUE SINCE THE SECOND BOUNDARY IS NOT LIKELY TO
PENETRATE INTO THE FORECAST AREA. A THIRD BOUNDARY MAY VERY WELL
MOVE THROUGH FRIDAY BUT ITS MOISTURE WILL ALSO BE LIMITED AND
SHOWER WILL BE ISOLATED THEN AS WELL. NO MAJOR EVENTS ARE EXPECTED
THROUGH 16 FEBRUARY...ALTHOUGH THE GFS HINTS AT SOUTHWEST FLOW TO
THE WEST AT THE END OF ITS RUN WHICH COULD BRING BETTER MOISTURE
LATER IN THE MONTH.

&&

.AVIATION...
PREVAILING VFR CONDS ARE EXPECTED ACROSS THE LOCAL FLYING
AREA...AND ALL TERMINAL AERODROMES DURING THE EVENING AND
OVERNIGHT HOURS. HOWEVER...WITH THE PREVAILING LIGHT EAST
SOUTHEAST LOW LEVEL WIND FLOW...OCCASIONAL PUFFS OF VA FROM
MONTSERRAT/TRPG WILL MAKE ITS WAY ACROSS TISX AT LEAST UNTIL
06/21Z...THEN LATER DRIFT WEST NORTHWEST WHILE BECOMING DIFFUSE
ACROSS PARTS OF THE SOUTH AND EAST SECTIONS OR PR DURING THE
OVERNIGHT HOURS. NO OTHER OPERATIONAL IMPACTS ANTICIPATED FOR THE
NEXT 24 HOURS.

&&

.MARINE...SWELL HAVE ALREADY REACHED OVER 8.5 FEET AT BUOY 41043
NORTH NORTHEAST OF SAN JUAN AND WILL BEGIN REACHING THE AREA LATE
THIS AFTERNOON AND TONIGHT. PERIODS WERE 13 SECONDS. THESE SWELL
WERE CREATED BY AN EXTRAORDINARY LOW IN THE NORTH CENTRAL
ATLANTIC. SWELL WOULD CONTINUE BEYOND SUNDAY BUT THE SWATH OF
REALLY STRONG WINDS AROUND THIS LOW WAS NARROW AND SEAS DIMINISH
QUICKLY. ANOTHER TRAIN OF WAVES IS EXPECTED IN THE AREA ON TUESDAY
FROM A SECOND LOW LEAVING THE VIRGINIA COAST. A MUCH LARGER EVENT
IS BEING INDICATED BY THE MODELS FOR THE FOLLOWING FRIDAY.

Good morning.
A cold front has moved down to the region and extends from the Nort Atlantic through the Gulf of Fonseca, the front is rather well defined but the associated ridge is weak so only a subtle decrease in temperatures is expected. The most noticeable effects of the fronts are weak northerly winds upto 25 km/h (15 mph) and a cloud cover that since yesterday has keep the maximum temperatures a little lower than on the last few days that were very warm. Tomorrow I will post the observations of winds and temperatures.
