.SYNOPSIS...A MID TO UPPER LEVEL TROUGH ACROSS THE NORTHWEST
ATLANTIC WILL MOVE EASTWARD ACROSS THE CENTRAL ATLANTIC THROUGH THE
NEXT SEVERAL DAYS. AS THIS HAPPENS...A COLD FRONT/SHEAR LINE WILL
MOVE RAPIDLY ACROSS THE LOCAL ISLANDS SATURDAY. AFTER THE FROPA A
DRIER AND STABLE AIR MAS WILL ENCOMPASS THE LOCAL REGION UNTIL AT
LEAST MID WEEK.
&&
.DISCUSSION...LATEST SATELLITE AND RADAR IMAGES THIS AFTERNOON
DEPICTED A SHEAR LINE ASSOCIATED WITH A COLD FRONT JUST ACROSS THE
NORTHWEST AND NORTH ATLANTIC COASTAL WATERS. THIS FEATURE IS
EXPECTED TO PROPAGATE/SINK TO THE SOUTH SOUTHEAST REACHING THE LOCAL
ISLANDS TONIGHT AND SATURDAY AND LASTING POSSIBLE UNTIL EARLY
SUNDAY. AN INCREASE IN CLOUDINESS...SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO DEVELOP ACROSS THE REGION IN ASSOCIATION TO THE PASS
OF THE COLD FRONT. AS THE COLD FRONT APPROACHES...THE LOW LEVEL
WINDS IS EXPECTED TO SHIFT FROM THE NORTHEAST...LATE THIS
AFTERNOON AND THIS EVENING...FOCUSING THE SHOWER ACTIVITY MAINLY
SOUTH OF CORDILLERA CENTRAL. STRONG SURFACE HIGH PRESSURE WILL
THEN BUILD ACROSS THE REGION AFTER THE FROPA...INDUCING A VERY DRY
WEATHER...WINDY CONDITIONS AND COLDER THAN NORMAL TEMPERATURES
SUNDAY...MONDAY AND TUESDAY NEXT WEEK. PWAT VALUES WILL REMAIN IN
THE RANGE OF 1.40-1.60 INCHES THIS EVENING...BUT WILL INCREASE TO
AROUND 2.0 INCHES TONIGHT AND SATURDAY AND DECREASING RAPIDLY
AFTER THAT.
&&
.AVIATION...NMRS SHRA/ISOLATED TSRA WILL CONTINUE TO DEVELOP
ALONG AND SOUTH OF CORDILLERA CENTRAL DURING THE REST OF THE
AFTERNOON AND THIS EVENING...PRODUCING MVFR OR EVEN IFR CONDITIONS
ACROSS TJPS UNTIL AT LEAST 13/23Z. ONLY VCSH ARE EXPECTED ACROSS
THE REST OF THE LOCAL TAF SITES THIS EVENING. SHOWERS THEN
INCREASE IN CVRG OVERNIGHT AND SATURDAY WITH PREDOMINANT MVFR
CIGS AND VSBYS IN MDT RAIN/SHRA AND EVENTUALLY USVI AND NCM SAT
NIGHT. THESE CONDITIONS WILL LIKELY PERSIST THROUGH 12Z SUN AS AN
UNSEASONABLY STRONG CDFNT SWEEPS THROUGH THE LOCAL FLYING AREA.

NATIONAL WEATHER SERVICE SAN JUAN PR
1011 PM AST FRI APR 13 2012
.UPDATE...INDUCED LOW LEVEL PREFRONTAL TROUGH MOVING ACROSS THE
REGION TODAY...IN COMBINATION WITH MID TO UPPER LEVEL INSTABILITY
AND LOCAL AND DIURNAL EFFECTS...GAVE WAY TO ACTIVE WEATHER CONDITIONS
DURING THE AFTERNOON AND EARLY EVENING HOURS. PERIODS OF LOCALLY HEAVY
RAINFALL ACROSS PARTS OF PUERTO RICO INCLUDING THE SAN JUAN METRO
AREA EVENTUALLY LEAD TO RAPID RIVER RISES...ALONG WITH URBAN AND
SMALL STREAM FLOODING. BY LATE EVENING THE ACTIVITY ACROSS THE
ISLANDS HAD MOVED OFF OR CONTINUED TO DIMINISH. DURING THE REST OF
THE OVERNIGHT HOURS HOWEVER EXPECT SHOWERS AND ISOLATED THUNDERSTORMS
TO DEVELOP JUST AHEAD AND ALONG THE FRONTAL BOUNDARY WHICH WAS NOW
JUST NORTHWEST OF THE FORECAST AREA. EXPECT THE BOUNDARY/SHEAR LINE
TO CONTINUE TO SINK SOUTHWARDS AS PREVIOUSLY MENTIONED AND AFFECT
THE LOCAL ISLANDS AND SURROUNDING WATER OVER THE WEEKEND. THEREFORE
INCREASING CLOUDINESS AND INSTABILITY ALONG WITH ACTIVE WEATHER
CONDITIONS CAN BE EXPECTED ON SATURDAY AND THROUGH SUNDAY. THIS
WILL BE FOLLOWED BY A RAPID IMPROVEMENT IN WEATHER CONDITIONS...AS
STRONG HIGH PRESSURE WITH BUILD ACROSS THE WEST AND SOUTHWEST
ATLANTIC AND USHER COOLER AND STABLE AIR ACROSS THE REGION. THIS
WILL HOWEVER INCREASE THE LOCAL PRESSURE GRADIENT AND THUS
INCREASE THE NORTH NORTHEAST TRADE WINDS.
IN ADDITION...SHORT PERIOD SWELLS WILL BUILD ACROSS THE ATLANTIC WATERS
ON SATURDAY AFTERNOON IN RESPONSE TO THE STRONG WINDS IN THE WAKE OF
THE APPROACHING COLD FRONTAL BOUNDARY. WIND DRIVEN SWELLS WILL QUICKLY
BUILD SATURDAY AFTERNOON... PEAKING EARLY SUNDAY MORNING. THIS WILL
RESULT IN SIGNIFICANT BREAKING WAVE ACTION ON ATLANTIC FACING COASTLINES.
THEREFORE A HIGH SURF ADVISORY WILL BE IN EFFECT FROM SATURDAY AFTERNOON
THROUGH AT LEAST SUNDAY. PLEASE REFER TO THE LATEST COASTAL AND MARINE
HAZARD MESSAGES.

As an air of déjà vu. Everywhere the Sargasso are returned in the waters of the butterfly island. And you, are you concerned by these algaes in PR and the Northern Leewards, Cycloneye and Msbee? What is the situation in your area?
The Sargasso are back!
France-Antilles Guadeloupe12.04.2012
http://www.microsofttranslator.com/bv.a ... 165959.php
Important colonies of Sargasso are approach. The phenomenon occurs earlier than last year.
All those attending a little coastal noted: some parts of the coast are again littered with Sargasso. Since several weeks, relatively small benches come in scattered ranks, on the North and South of the great earth. It appears that this is only a hors d'oeuvres: air recognition made here a few days via the mounted police helicopter have identified most important banks to a few tens of kilometres of the coast.
Last year, the invasion took place in July. Appearing March seems augurer suit, or an amplification of the phenomenon. But what phenomenon? The study commissioned by the authorities on the origin of these brown tides is not yet entirely completed and unlikely in any event that the administration communicates its results during the current period of "reserve" election-related. The hypothesis, however, overflow or drift of the Sargasso Sea, by biologist Félix Lurel, - coupled with a massive influx of nutrients (silts) from the Amazon, promoting the proliferation of algae - seems to confirm.
MANAGEMENT PLAN
The arrival of recent weeks raise a doubt: these brown tides are not a one-time phenomenon and will have to get used to living with them. Not necessarily every year, but regularly. Hence the importance of preparing a management plan, to which the authorities are attached in the past months.
Learn about the origin of the phenomenon and the elements that determined it, it is important: term, it will allow to predict if one is in the presence or no year to Sargassum. But it will not be provided to limit the effects related to the arrival and the grounding of these algae. The phenomenon of the year past, first of its kind, allowed lessons (read below) and wipe casts, including in terms of cleaning.
ESSENTIAL CLEANING
What remains certain, it is that the decomposition of the Sargasso can have adverse effects on health. Gwad measurements of Air at the request of the regional agency of health (ARS), Petit-Bourg and Sainte-Anne, demonstrated the risks associated with chronic exposure to hydrogen sulfide that they emit. Cannot therefore make the economy of cleaning of a part of the coast, at least those where houses are adjacent to the beaches affected by the phenomenon.
-A wound for fishermen
Sargasso were drained in their wake of the banks of small bream, and fishermen practising behind found some interest, although move in a sea of algae is not a sinecure. But the disadvantages for the fishermen in the net are major: filled with algae, gear do virtually nothing and weigh a dead donkey when it comes to raise them.
Finally, algae - that have sometimes made completely inaccessible ports - coil in the engine propellers, causing more frequent outages.
-Station chronic exposure
If an occasional exposure to hydrogen sulfide released by Sargasso decaying - that of a bath, a fisherman - presents no risk, chronic exposures, i.e. those of persons living regularly in close proximity, may have effects. Petit-Bourg (Sarault) and Sainte-Anne, the measures have highlighted exposure concentrations greater than the reference value. "In this case, the occurrence of the associated health effects is not to neglect", indicates Gwad'Air, in a study conducted at the request of the regional health agency (ARS). These effects depend on the dose and duration of exposure to hydrogen sulfide. They range from irritation of the eyes to impairment of the central nervous system, or even death, from the loss of the sense of smell. The study thus advocates "a collection of algae before decomposition began: today is the more safely reduce toxic emissions from this decomposition".
-It has said Nathalie, resident of Petit-Bourg: "it is already untenable."
"The Sargasso returned since 4 weeks." It took only a few days so the smell - that of rotten eggs - moved. In the evening, when the wind turns and it comes from the sea, it is untenable. There is no choice, on farm doors and Windows. But the smell is still suggests and it permeates everything. Indeed, in the borough, seaside Parkway is deserted, as usual, we meet retirees who take air and discuss... »
-HIS view of Yvon, submarine Hunter: "let make nature."
"I attended many shoreline, to find points of water." In some locations, advanced castles including, in August and September, I saw real walls of Sargassum on a good metre. Fifteen days later, there were more a trace. What sea does, often, the won. This is less true when the algae penetrate deep and narrow bays.
Gate of hell (Anse-Bertrand) or Bay Olive (the mold), algae have remained and decomposed during weeks. The water became brownish and beyond the pale. I have hunted in lagoons where Sargasso benches were imprisoned. It is true that under these banks, many fish predators, snapper and Jack fish include. But swim through the Sargasso, it is a test, especially when the banks are thick. I understand perfectly that it may slow or even stop a boat. Last thing. I have collected a few bags for use in my garden. I confirm: as they decompose, they remove the sooty mould. »
-A financial precipice
The Sargasso return and will be costly to the community. Collection operations cost, in 2011, hundreds of thousands of euros - 40 000 Desirade alone - for disappointing results: the collection, implementation by the Union of the sites and the beaches, was barely made that a new Brown tide was... No long-term disposal solution was stopped. Compost is an option, but at a cost of 50 euros/tonne. In the term, these algae, briefly dried, could be incinerated.

Re: Caribbean - Central America Weather
Good morning. The rain has arrived in PR and the Virgin Islands. I will send some to our friends in the islands that are in a drought right now 
AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE SAN JUAN PR
520 AM AST SAT APR 14 2012
.SYNOPSIS...A MID TO UPPER LEVEL TROUGH ACROSS THE WESTERN ATLANTIC
WILL CONTINUE TO MOVE EASTWARD THROUGH SUNDAY MORNING...PUSHING A
FRONTAL BOUNDARY ACROSS THE LOCAL ISLANDS TODAY. AN OVERALL DRIER
WEATHER PATTERN WILL DOMINATE THE FORECAST AREA EARLY NEXT WEEK.
&&
.DISCUSSION...TROUGH ALOFT WILL CONTINUE TO MOVE EASTWARD ACROSS
THE WESTERN ATLANTIC THROUGH SUNDAY MORNING PUSHING A FRONTAL
BOUNDARY ACROSS THE LOCAL ISLANDS TODAY. JET MAXIMA ASSOCIATED
WITH AFOREMENTIONED UPPER LEVEL TROUGH WILL MOVE TO THE EAST-
SOUTHEAST WITH THE LOCAL ISLANDS TO REMAIN ON THE DIVERGENT SIDE
OF THE JET THROUGH AT LEAST SUNDAY MORNING.
FRONTAL BOUNDARY AND ASSOCIATED MOISTURE WILL SLOWLY SINK
SOUTHWARDS OVER THE LOCAL REGION THROUGHOUT THE DAY. THIS WILL
BRING FAIRLY ACTIVE WEATHER CONDITIONS TO THE LOCAL ISLANDS AND
SURROUNDING WATERS THROUGH AT LEAST EARLY SUNDAY MORNING. A
STRONG HIGH PRESSURE WILL BUILD ACROSS THE LOCAL ISLANDS AFTER
THE FRONTAL PASSAGE...RESULTING IN DRIER AND WINDY CONDITIONS
ACROSS THE FORECAST AREA BY LATE SUNDAY MORNING. WINDS ON SUNDAY-
MONDAY ARE FORECAST TO PEAK AT 20-25KT.
&&
.AVIATION...CDFNT WILL MOVE THROUGH THE LOCAL FLYING AREA TODAY
THROUGH SUN AND WILL BE ACCOMPANIED WITH FREQ SHOWERS AND ISOLATED
THUNDERSTORMS. EXPECT CONDITIONS TO BECOME PREDOMINANT MVFR AFTER
12Z TODAY IN -RA AT JBQ/JSJ AND IST AND THEN EVENTUALLY ACROSS
JPS...ISX AND LEEWARD TERMINALS TONIGHT. WINDS WILL ALSO PICK UP
SUBSTANTIALLY AT ALL TERMINALS THIS EVENING WITH SUSTAINED WINDS
20G30KT XCPT JPS WHERE LAND FRICTION WILL BE GREATEST. GAP AND
KATABATIC WINDS AT MAYAGUEZ AND ST. THOMAS RESPECTIVELY COULD RESULT
IN FURTHER ACCELERATION OF WINDS WITH GUSTS POSSIBLY EXCEEDING 35
KTS OR MORE. CIGS IMPROVE TO VFR BY 15Z SUN AS RAIN TAPERS OFF AND
WINDS DIMINISH ON MON.
&&
.MARINE...WINDS AND SEAS INCREASE SHARPLY THIS EVENING AS ATLC
HIGH PRES STRENGTHENS. AM VERY CONFIDENT THAT WE`LL SEE 25KT WINDS
ACROSS THE WATERS ESPECIALLY THROUGH THE PASSAGES AS AIR FUNNELS
DOWN. USING WAVE HEIGHT NOMOGRAMS THIS YIELDS SEAS UP TO 9 FT WHICH
IS LOWER THAN THE 11 FEET FCST BY WW3. WINDS BEGIN TO DIMINISH MON
AFTERNOON AND HAVE LOWERED SEAS BELOW 7 FT BY MON NIGHT AT MIDNIGHT
AS SEAS SHOULD SUBSIDE QUICKLY AS WINDS DIMINISH. ALSO...MARINE
MODELS HAVE A BIAS OF KEEPING SEAS TOO HIGH AFTER SIG SURGES IN
WINDS.

.HYDROLOGY...RAIN WILL FALL THROUGH THE DAY PRETTY MUCH OVER THE
WHOLE ISLAND AND THE USVI ESPECIALLY LATE TODAY THROUGH MIDNIGHT
TONIGHT. RAINFALL ACCUMULATIONS ARE EXPECTED TO AVERAGE BETWEEN
ONE TO TWO INCHES NORTH OF THE CORDILLERA WITH THE HEAVIEST
AMOUNTS ACROSS NORTHEAST PR. SOUTH OF THE CORDILLERA AMOUNTS WILL
BE GENERALLY LESS THAN ONE INCH. WHILE THERE IS SOME CONCERN FOR
FLOODING ESPECIALLY ACROSS NORTHEAST PR WHERE THE HEAVIEST AMOUNTS
ARE EXPECTED...THESE AMOUNTS ARE EXPECTED TO FALL OVER A 12-HR
PERIOD AT MODERATE INTENSITY. ALSO THE PROGRESSIVE NATURE OF THIS
FRONT ARGUES AGAINST SIGNIFICANT RAINFALL ACCUMULATIONS. WHILE
RISES CAN BE EXPECTED IN SOME OF THE RIVERS IN THOSE AREAS ALREADY
MENTIONED. THE PROB OF FLASH FLOODING SEEMS TOO LOW ATTM TO
WARRANT A FLASH FLOOD OR A FLOOD WATCH. HOWEVER...DO EXPECT TO SEE

Good morning Cycloneye, thanks to you. Nothing at the horizon for now, maybe for tonight matter of timing? 
The plants could be happy if this trend verifies, but let's wait a bit...

No problem Barbara. It is supposed to arrive today and the conditions should deteriorate tonight and stalled until tommorow morning in the Northern Leewards. Guadeloupe should begin deal with this episode tommorow afternoon and until Monday morning if the timing stay like that, as Meteo-France predicted on its last weather forecast 6AM.

Re: Caribbean - Central America Weather
Good morning. Macrocane,here is also cooler than normal as the Cold Front has moved thru PR .Fairly strong fresh North to Northeast winds has caused the NWS to issue a Wind Advisory for higher elevations in PR. The rain has diminished and rivers are going down after a wet Saturday. It looks like most of next week will be drier.
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN JUAN PR
937 PM AST SAT APR 14 2012
.UPDATE...SHOWERS HAVE DIMINISHED CONSIDERABLY OVER PUERTO RICO
AND ALMOST ALL RIVERS...SAVE THE RIO GRANDE DE ARECIBO IN
ARECIBO...HAVE CRESTED AND ARE NOW FALLING SLOWLY. WINDS HAVE
INCREASED AND ARE RUNNING BETWEEN 15 TO 20 MPH EXCEPT ON THE SOUTH
SIDE OF THE CORDILLERA CENTRAL WHERE CONSIDERABLE SHELTERING IS
TAKING PLACE. THERE HAVE BEEN GUSTS IN THE RANGE OF 25 TO 35 MPH
WITH SOME SHOWERS. GUSTS WERE SLIGHTLY HIGHER IN SAINT THOMAS.
PRECIPITABLE WATER IN THE 15/00Z SOUNDING WAS 1.91 INCHES WITH
SOME INSTABILITY...THEREFORE LOOK FOR AT LEAST SCATTERED SHOWERS
OVER MOST OF PUERTO RICO...WITH OCCASIONAL SHOWERS OVER THE
NORTHEAST COASTS AND FOOTHILLS THROUGH MOST OF THE NIGHT. AS OF
15/0123Z SHOWERS WERE SEEN OVER AND JUST NORTH OF SAINT CROIX.
THESE HAVE TOPS OF 30 TO 35 KFT AND MAY CONTAIN AND ISOLATED
THUNDERSTORMS. THEREFORE WILL KEEP SHOWERS AND ISOLATED
THUNDERSTORMS IN THE FORECAST THERE.
&&
.DISCUSSION...HIGH PRESSURE IS NOW BUILDING INTO THE ATLANTIC
OCEAN NORTH OF THE AREA AND WINDS ARE RISING. RADAR NOW INDICATES
25 KNOTS BETWEEN 3 TO 5 THOUSAND FEET...BUT SUSTAINED WINDS AT THE
SURFACE ARE LESS THAN THIS CRITICAL THRESHOLD. NEVERTHELESS THIS
HAS DRIVEN SEAS ABOVE 7 FEET AT BOTH BUOY 41043 AND 41053.
PERIODS...HOWEVER ARE 8 SECONDS OR LESS AND WILL MAKE FOR ONLY
MARGINAL HIGH SURF. THESE WINDS AND WAVES WILL DRIVE STRONG
CURRENTS AND WILL CONTINUE WITH THE ADVISORY. FORECAST MODELS ARE
SHOWING ANOTHER WAVE OF SHOWERS BOTH OVERNIGHT SUNDAY INTO MONDAY
AND OVERNIGHT MONDAY INTO TUESDAY AND HAVE RAISED POPS ON THE
NORTH COAST AND NORTHERN VIRGIN ISLANDS TO CHANCE OF SHOWERS
ACCORDINGLY. LIGHTEST WINDS BELOW 50 KFT NOW APPEAR TO BE NORTH AT 5
TO 10 KNOTS BETWEEN 10 AND 15 KFT.
