Potentially irritating Sargassum algae
http://www.microsofttranslator.com/bv.a ... 133227.php

V.D. France-Antilles Guadeloupe01.08.2011

As Martinique and Guyana, algae Sargassum we poison the life. For some time now, these Brown algae invading some beaches and odour generated by their decomposition is not pleasant. It starts from 12 to 48 hours after the grounding. In addition to the olfactory discomfort, Prefecture and regional health agency (ARS) indicate that "This decomposition, coupled with a high concentration of algae, is at the origin of the emission of hydrogen sulfide (H2S)". There is catastrophic, but attention anyway. "Inhaling this gas may produce irritation of the eyes and the respiratory tract, particularly for sensitive populations (people who have difficulty breathing, asthma, elderly, infants, pregnant...) to moderate dose." In the case of accidental inhalation of this gas, should consult her physician.

Prefecture advises the population, especially the residents, visitors, walkers and generally all those who engage in nautical and maritime activities:

-to avoid walking on the so-called Brown algae "Sargasso" stranded on the shores

-to respect the instructions of prohibition of access to the beach or swimming that could be put in place by the municipalities concerned.

"Review of the evolution of these algae deposits continue to be provided by the State services, which will undoubtedly, if necessary, to disseminate information to the address of the population."

I heard on one of the weather reports that Haiti could get as much as 20 inches of rain.
I hope not.

10+ in Ponce as the highest total so far,and between 6-9 inches overall as average in the rest of the island.

[Gustywind]

So Cycloneye that's huge amounts of water in PR . Be safe and dry. Thanks to keep us informed of the situation.

[cycloneye]

To clarify,those rainfall amounts in PR are for the past 24 hours since Wednesday morning until Thursday morning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
303 PM AST THU AUG 4 2011

.SYNOPSIS... TROPICAL STORM EMILY LOCATED THIS AFTERNOON MOVING
SLOWLY WEST AWAY FROM THE LOCAL AREA. SURFACE HIGH PRESSURE
ACROSS THE CENTRAL ATLANTIC WILL BUILD ACROSS THE REGION DURING
THE NEXT FEW DAYS. SAL WILL MOVE ACROSS THE REGION LATE TONIGHT
THROUGH SATURDAY NIGHT.

&&

.DISCUSSION...CLOUD COVER AND A DRIER AIR MASS HAS LIMITED THE
SHOWER ACTIVITY ACROSS THE REGION THIS AFTERNOON. LATEST SATELITE
IMAGES AS WELL AS NAAPS AEROSOL MODEL SHOWED A BIG AREA OF SAHARAN
DUST EXTENDING SEVERAL HUNDRED MILES EAST OF THE LESSER ANTILLES
AND ACROSS THE U.S. VIRGIN ISLANDS AND PUERTO RICO. THIS AREA WILL
MOVE WEST DURING THE NEXT FEW DAYS AND WILL INDUCE RELATIVELY DRY
CONDITIONS AND HAZY CONDITIONS DURING THE WEEKEND. HOWEVER...AVAILABLE
MOISTURE MAINLY AT THE SURFACE...WILL BE ENOUGH TO PRODUCE SHOWERS
AND ISOLATED THUNDERSTORMS MAINLY ACROSS THE WESTERN INTERIOR AND
NORTHWEST SECTIONS OF PUERTO RICO EACH AFTERNOON.

&&

.AVIATION...VFR CONDITIONS SHOULD PREVAIL THROUGH THE TAF PERIOD AS
SAHARAN DUST STARTS TO MAKE ITS WAY INTO THE LOCAL AREA. THE SAHARAN
DUST WILL START TO GET MORE DENSE AFTER 05/06Z. THE WINDS WILL BE
EAST SOUTHEAST FROM 5 TO 15 KTS BETWEEN THE SURFACE AND 15K FT.

&&

.MARINE...SURFACE HIGH PRESSURE ACROSS THE CENTRAL ATLANTIC AND
TROPICAL STORM EMILY NOW LOCATED SOUTH OF HISPANIOLA...WILL
MAINTAIN A FRESH TO LOCALLY STRONG SOUTHEASTERLY WIND FLOW ACROSS

Emily was downgraded to a remnant,but still heavy rains will fall in DR and Haiti.That is why we will continue to watch that situation.

Good morning. Haze invades the Eastern Caribbean along with dry air to cause a good weather weekend.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
459 AM AST FRI AUG 5 2011

.SYNOPSIS...
MID TO UPPER LEVEL CLOUDINESS ASSOCIATED WITH REMNANTS OF TROPICAL
STORM EMILY CONTINUED TO DIMINISH ACROSS THE AREA...AS THE CLOUD
DEBRIS AND MID TO UPPER LEVEL HIGH PRESSURE RIDGE EXTENDING ACROSS
THE REGION FROM THE WEST ATLANTIC...LIFTS WEST NORTHWEST. A TUTT
NORTHEAST OF THE NORTHERN LEEWARDS WILL SLOWLY BECOME MORE AMPLIFIED
AND SINK SOUTHWEST INTO NORTHEAST CARIBBEAN...AS AN ASSOCIATED
UPPER LOW FORMS JUST NORTHEAST OF THE REGION BY SATURDAY. THE TUTT
WILL THEN GRADUALLY SHIFT WEST NORTHWEST ACROSS THE REGION BY SUNDAY
INTO MONDAY. MEANWHILE THE STRONG ATLANTIC HIGH WILL BUILD ACROSS
THE LOCAL REGION THROUGH SUNDAY...AS THE SURFACE LOW ASSOCIATED
WITH REMNANTS OF WHAT WAS TROPICAL STORM EMILY MOVES FURTHER WEST
AND AWAY FROM THE LOCAL AREA. THIS OVERALL PATTERN WILL CREATE A
SUBSIDENCE CAP IN THE UPPER LEVELS...AND MAINTAIN A MODERATE
SOUTHEASTERLY FLOW ACROSS THE REGION TODAY THROUGH SATURDAY...THEN
BECOME MORE EASTERLY BY SUNDAY.

&&

.DISCUSSION...
SATELLITE IMAGERY AS WELL AS MIMIC TPW AND NAAPS AEROSOL MODEL
SHOWED A LARGE AREA OF SAHARAN DUST AND DRY AIR LAYER EXTENDING
SEVERAL HUNDRED MILES EAST OF THE LESSER ANTILLES INTO THE U.S.
VIRGIN ISLANDS AND PUERTO RICO. THIS WILL CONTINUE TO SPREAD
WESTWARD ACROSS THE AREA DURING THE NEXT FEW DAYS...AND WILL
BRING RELATIVELY DRIER AND HAZY CONDITIONS DURING MUCH OF THE
WEEKEND. HOWEVER...AVAILABLE MOISTURE...WILL BE SUFFICIENT TO
PRODUCE SHOWERS AND ISOLATED THUNDERSTORMS MAINLY ACROSS THE WESTERN
INTERIOR AND NORTHWEST SECTIONS OF PUERTO RICO EACH AFTERNOON. OVER
THE WEEKEND...EXPECT LINGERING MOISTURE ALONG WITH LOCAL AND DIURNAL
EFFECTS TO INDUCE AFTERNOON CONVECTION ONCE AGAIN ACROSS PARTS OF
THE ISLANDS EACH DAY...HOWEVER NO WIDESPREAD RAINFALL IS EXPECTED
AT THIS TIME. THE DRY TREND SHOULD ONLY LAST UNTIL SUNDAY...AS THE
UPPER RIDGE IS FORECAST TO GRADUALLY ERODE AND PULL WEST AS THE
ABOVE MENTIONED TUTT RETROGRADES OVER THE NORTHEAST CARIBBEAN.

LATEST MODEL GUIDANCE SUGGESTS THAT A LOW LEVEL INDUCED LOW LEVEL
TROUGH FORECAST TO MOVE ENTER THE NORTHEAST CARIBBEAN LATE SUNDAY
INTO MONDAY. THIS WILL BE QUICKLY FOLLOWED BY THE NEXT TROPICAL
WAVE ON TUESDAY OF NEXT WEEK. THESE TWO FEATURES IN COMBINATION
WITH THE TUTT WHICH IS ALSO FORECAST TO MOVE ACROSS THE NORTHEAST
CARIBBEAN WILL BRING INCREASING MOISTURE AND INSTABILITY TO THE
LOCAL REGION AND THUS INCREASE THE CHANCES FOR ADDITIONAL SHOWERS
AND THUNDERSTORM DEVELOPMENT ACROSS THE ISLANDS AND SURROUNDING
WATERS DURING THE EARLY PART OF THE UPCOMING WEEK.

&&

.AVIATION...VFR CONDITIONS SHOULD PREVAIL THROUGH THE TAF PERIOD AS
SAHARAN DUST STARTS TO MAKE ITS WAY INTO THE LOCAL AREA. THE SAHARAN
DUST LAYER WILL START TO GET MORE DENSE THROUGHOUT THE DAY CREATING
HAZY CONDS ACROSS THE FLYING AREA. THE WINDS WILL BE EAST SOUTHEAST

308 PM AST FRI AUG 5 2011

.SYNOPSIS...SAL IN THE AREA HAS KEPT OUR AREA DRY...WARM...AND HAZY.
LOCAL TEMPERATURES HAVE BEEN WARM...WITH A MAX TEMP OF 90 AT THE SAN
JUAN AIRPORT. EXPECT SAL TO BE PRESENT FOR THE REST OF TODAY AND
INTO SUNDAY MORNING WITH MAX TEMPS IN THE 90S TOMORROW.


&&

.DISCUSSION...THE REMNANTS OF EMILY ARE EXPECTED TO MOVE NORTH AND
THEN NORTHEAST AND OUT OF THE AREA AS HIGH PRESSURE BUILDS NORTH
OF THE LOCAL AREA IN THE NEXT FEW DAYS. SAHARAN DUST PRESENT IN
THE AREA AT THIS TIME IS EXPECTED TO CONTINUE THROUGH TOMORROW AND
POSSIBLY INTO SUNDAY...GIVING US MUCH DRIER
CONDITIONS...SIGNIFICANTLY LIMITING SHOWER AND THUNDERSTORM
POTENTIAL. FORECAST SOUNDINGS...ESPECIALLY THE NAM...SHOWS A
DRYING TREND FOR TOMORROW AND SLOWLY SHOWING MOISTURE MOVING IN
FROM THE SOUTHEAST ON SUNDAY. NAM FORECAST SOUNDINGS SHOW PW
VALUES AS LOW AS 1.17 FOR TOMORROW SATURDAY AT 18Z AND INCREASING
TO THE 1.80 RANGE FOR SUNDAY AT 18Z. INSTABILITY ALSO INCREASES
FOR SUNDAY SO THUNDERSTORM POTENTIAL SHOULD INCREASE IF THE SAL IS
MINIMAL OR GONE.

FURTHER OUT IN THE FORECAST PERIOD...A SURGE OF MOISTURE MAY BE
HEADING OUR WAY ON TUESDAY TO WEDNESDAY WITH A TROPICAL WAVE. THE
GFS SHOWS A TROPICAL WAVE ENTERING OUR AREA ON 18Z
TUESDAY AND LINGERING UNTIL 18Z WEDNESDAY...ONCE AGAIN GIVING US
AN INCREASED CHANCE OF SHOWERS AND THUNDERSTORMS.

Good morning. Hazy and dry weather will continue today for Puerto Rico/Virgin Islands.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
541 AM AST SAT AUG 6 2011

.SYNOPSIS...STRONG SURFACE HIGH PRESSURE ACROSS THE NORTH CENTRAL
ATLANTIC AND BROAD EQUATORIAL TROUGH SPREADING NORTHWARDS ACROSS
THE EASTERN CARIBBEAN WILL HELP MAINTAIN MODERATE TO STRONG EASTERLY
TRADES ACROSS THE REGION THROUGH THE WEEKEND. THIS DOMINANT FLOW WILL
HELP TO SPREAD THE SAHARAN AIR LAYER/SAL ACROSS THE REGION THROUGH
THE WEEKEND. TUTT AND ASSOCIATED LOW LOCATED ACROSS THE NORTH CENTRAL
ATLANTIC...EXTENDING SOUTHWEST TO JUST NORTHEAST OF THE REGION...WILL
SLOWLY RETROGRADE WESTWARD OVER THE ISLANDS BY LATE SUNDAY AS UPPER
HIGH SHIFTS WESTWARD. THIS WILL EVENTUALLY ALLOW FOR MORE FAVORABLE
CONDITIONS FOR NOCTURNAL AND DIURNAL CONVECTION ACROSS THE REGION.

&&

.DISCUSSION...THE DRY AND SUBSIDENT AIR LAYER ACROSS THE REGION
WILL TRANSLATE TO OVERALL HOT AND AND HAZY CONDITIONS...WITH LOCAL
TEMPERATURES TO AGAIN TO RANGE IN THE HIGH 80S TO LOW 90S. A FEW
LIGHT EARLY MORNING SHOWER MAY BRUSH THE COASTAL AREAS... WITH
MOSTLY SUNNY BUT HAZY CONDITIONS EXPECTED TO PREVAIL ACROSS MUCH
OF THE ISLANDS. THE INTENSE HEAT AND LOCAL EFFECTS MAY LEAD TO A
FEW AFTERNOON SHOWERS AND POSSIBLY AN ISOLATED THUNDERSTORM OVER
PARTS OF THE INTERIOR AND WEST SECTIONS OF PUERTO RICO. HOWEVER EXPECT
THE DIURNALLY DRIVEN ACTIVITY TO QUICKLY DIMINISH BY SUNSET. SIMILAR
CONDITIONS EXPECTED FOR MUCH OF SUNDAY...BUT BY LATE EVENING INTO
EARLY MONDAY...EXPECT THE ARRIVAL OF A TUTT INDUCED EASTERLY PERTURBATION.
THIS FEATURE ALONG WITH THE PROXIMITY OF THE TUTT WILL INCREASE THE
CHANCES FOR ENHANCED CONVECTION ACROSS THE REGION. A TROPICAL WAVE
WILL QUICKLY FOLLOW AND IS SO FAR FORECAST TO MOVE ACROSS THE EASTERN
CARIBBEAN TUESDAY THROUGH WEDNESDAY.

&&

.AVIATION...
VFR CONDITIONS WILL CONTINUE ACROSS ALL TAF SITES THROUGH THE FORECAST
PERIOD. SUSPENDED SAHARAN DUST PARTICULATES WILL SPREAD ACROSS THE
REGION OVER THE NEXT 24 TO 36 HOURS. HOWEVER...VIS WILL REMAIN P6SM.
