Hi Luis
That's a beautiful sight right? LOL
I'm lovin' the sunshine!
and the water is clearing up too. This is what it looked like a few days ago.

Image

and the salt pond overflowed and the tarpon in the salt pond were just flopping around in the streets. The kids were having fun catching them.

I'm glad things are clearing up in PR too.
and VERY glad there were no fatalities.
As bad as this was, it could have been worse.

Regional service of Guadeloupe BP 451 - 97183 ABYMES
On Thursday, October 7th, 2010 at 4:30 pm
:rarrow: http://www.meteo.fr/temps/domtom/antill ... gd_loc.pdf
Exceptional rains.

The tropical storm OTTO centred enough far from to us, in the North of Dominican Republic, generated on Lesser Antilles an exceptional pluvio-stormy episode accompanied with intense electromagnetic effects causing numerous strikings by lightning. The whole Guadelupian archipelago and islands of the North underwent the effects of this vast particularly unstable cloudy block. The exceptional movement from west to east of this disturbance made hillsides West of the relief more exposed than to the common and the supply hasten streams provoked a fast rise in the water level. Causing numerous damages.
During the last four days, the rainy heights of meditative rain turn out locally important susceptible to occur every 20 years:
- 248 mm in Basse-Terre
- 222 mm to Bellevue at Pointe-Noire
- 308 mm in Grand-Case, Sint Marteen
- 360 mm to Sint Barth

The activation which occurred last night between 8 pm and 02 am in the morning on Guadeloupe (that is in 6 hours of time) intervenes while grounds are saturated by important rains of the last days. The heights of rain collected on this episode are remarkable for October and for a not cyclonic phenomenon:
- 99 mm in Basse-Terre
- 125 mm to Bellevue Pointe-Noire
- 118 mm in Grand-Case, Sint Marteen


We stay nevertheless far from the 392 mm of the cyclone JOSE on November 18th, 1999 in Sint Marteen and
362 mm of the cyclone MARILYN on September 14th, 1995 at Pointe-Noire.
At the time of the publication of this press relasead, important rains still occur on the Northern Leewards.

Hi guys! I'm glad that some of the isalnds have seen the sun today, in El Salvador the winds diminished a lot today but the morning was still cool, I have posted some observations of this event in the "Central America Cold Surges" thread, if you want to see them they're here under the title of "First Cold Surge of the 2010-2011 season": http://www.storm2k.org/phpbb2/viewtopic.php?f=22&t=106879&p=2082536#p2082536

2010 is already the wettest year since reliable records bagan in El Salvador. Here's what the SNET said on september 28 (translated with miscrosoft translator and edited a little by me):

Matthew increases the rainfall to 30.7% above the historical average
Tuesday 28 September 2010.

Since January 1 until September 27, 2353 mm (92.6 inches) of rain have been accumulated throughout the country. This is 30.7% above the annual average registered in previous years.. The accumulated rainfall this year exceeds the normal value of annual rain that corresponds to 1800 mm (70.9 inches). The accumulated rainfall this year is already higher than the previous record of 2181 mm (85.9 inches) in 2005.

According to the records of the national network of meteorological stations, the rains from Matthew in El Salvador exceeded 200 mm. The maximum amount was recorded in Santiago de María, Department of Usulután with an amount of 253.4 millimetres (mm), followed by the Los Andes station in Santa Ana, with 226 mm (mm). Other two places where water quantities exceeded the 100 millimetres of precipitation were Chiltiupán in La Libertad with 112.4 mm and 112.1 in Acajutla.

The influence of Tropical storm Matthew began in the country Friday 24th and lasted through Sunday 26 when it was downgraded to tropical depression in the Mexican territory. Furthermore, the Intertropical Convergence zone approached the Central American region producing moderate and occasionally very strong rains. Tropical storm Matthew is the 13th named cyclone in the Atlantic Ocean according to the National Hurricane Center. This same entity predicted a very active hurricane season for the Atlantic, foreseeing 18 cyclones named when the historical average is 10.

Hi Gusty
the translator didnt quite work but I see the picture.
Lionfish!
and we are seeing them in our waters too. More and more reports every day

http://www.smn-news.com/component/conte ... forts.html

They are really going to be a problem for the Caribbean.


and as far as the children fishing, I found out they actually were helping out local Nature Foundation in rescuing trapped fish and returning them to the salt pond.

I have heard news about this in recent weeks, but so far, no close encounter by beachgoers with those lionfish.

Good morning.


AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
615 AM AST SUN OCT 10 2010

.SYNOPSIS...MID TO UPPER LEVEL HIGH PRESSURE CENTERED OVER THE AREA
WILL REMAIN IN CONTROL OF THE REGION THROUGH MUCH OF NEXT WEEK. TROPICAL
WAVE NOW ACROSS THE EASTERN CARIBBEAN IS EXPECTED TO MOVE ACROSS
THE REGIONAL WATERS LATE TONIGHT THROUGH MONDAY NIGHT.

&&

.DISCUSSION...RELATIVELY STABLE CONDITIONS CONTINUE TO PERSIST
ACROSS THE LOCAL AREA THROUGH MUCH OF THE DAY...DUE TO THE
SUBSIDENCE AHEAD OF THE TROPICAL WAVE. LATEST SATELLITE IMAGERY
AND RADAR OBSERVATIONS INDICATES NEARLY CLOUD FREE CONDITIONS
ACROSS PUERTO RICO AND THE VIRGIN ISLANDS. THE GPS SOUNDER SHOWS A
DECREASING TREND IN PWAT VALUES IN THE LAST 6 HOURS...WITH VALUES
AROUND 1.7 INCHES. THIS TREND IS EXPECTED TO CONTINUE...ACCORDING WITH
THE GFS AND NAM FORECAST SOUNDINGS THAT INDICATE PWAT VALUES
DECREASING UNTIL LATE MORNING HOURS BEFORE INCREASE AGAIN AS THE
TROPICAL WAVE APPROACH TO THE LOCAL AREA LATER TODAY. CURRENTLY THE
WAVE IS LOCATED ACROSS THE EASTERN CARIBBEAN. THIS PERTURBATION IS
MOVING TOWARD THE WEST NORTHWEST AND IS EXPECTED TO CROSS THROUGH
SAINT THOMAS AROUND 11/00Z AND SAN JUAN AROUND 11/15Z. DESPITE THE
TROPICAL WAVE SHOWS NO SIGNIFICANT CONVECTION IN THE LATEST IR
IMAGERY...THIS WAVE AND ITS ASSOCIATED MOISTURE WILL INTERACT
WITH LOCAL EFFECTS...TO PRODUCE SHOWERS AND THUNDERSTORMS...PERIODS
OF HEAVY RAINFALL...LIGHTNING AND LOCALLY GUSTY WINDS ACROSS THE
LOCAL ISLANDS...BEGINNING LATE TONIGHT/EARLY MONDAY AND THEN
LIKELY CONTINUING THROUGH MONDAY NIGHT.

LOOKING AHEAD...MOISTURE WILL PROBABLY LINGER THROUGH TUESDAY...
RESULTING IN ADDITIONAL DAY OF ACTIVE WEATHER. AN OVERALL "DRIER"
AND MORE STABLE WEATHER PATTERN IS CURRENTLY INDICATED BY THE
GLOBAL GUIDANCE...BEGINNING TUESDAY NIGHT AND POSSIBLY CONTINUING
THROUGH FRIDAY.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED THROUGH 10/17Z ACROSS ALL
TAF SITES. AFT 10/17Z...BRIEF MVFR CONDS POSSIBLE IN AND AROUND TJSJ
AND TJBQ IN SHRA/TSRA. MTN OBSCURATIONS ARE EXPECTED AFT 10/16Z IN

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN JUAN PR
1104 AM AST SUN OCT 10 2010

.UPDATE...SUBSIDENCE AND DRYING IN PLACE ACROSS THE AREA AS SEEN
ON 12Z RAOB/ACARS AND BLENDED TPW IMAGERY BUT MOISTURE ADVECTION
ALREADY UNDERWAY ACROSS THE USVI. LATEST SHORT TERM GUIDANCE SHOWS
THAT BULK OF THE MOISTURE ASSOCIATED WITH TROPICAL WAVE WILL NOT
REACH PR UNTIL AFTER 21Z. SO BELIEVE MOST OF THE DAY WILL BE DRY
SO HAVE REDUCED POPS CONSIDERABLY XCPT FOR NW PR AND USVI WHERE
AN ISOLD SHRA/TSRA MAY STILL DEVELOP. OTHERWISE HOT AND SUNNY WITH
BEST CHANCES OF CONVECTION AFTER SUNSET MAINLY ACROSS SE PR AND
THE USVI.

&&

.AVIATION...VFR CONDITIONS XPCT FOR POSSIBLE MVFR CIGS AT JBQ/ISX
THIS AFTERNOON WITH SCT TSRA. BETTER CHANCES FOR CONVECTION TONIGHT.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
242 PM AST SUN OCT 10 2010

.SYNOPSIS...TROPICAL WAVE WILL AFFECT THE LOCAL AREA TONIGHT
THROUGH MONDAY. HIGH PRESSURE WILL DOMINATE THE LOCAL AREA DURING
THE NEXT SEVERAL DAYS.

&&

.DISCUSSION...PLENTY OF SUNSHINE HAS PREVAILED ACROSS PUERTO RICO
AND THE U.S. VIRGIN ISLANDS TODAY...FINALLY. AN AREA OF DRY AIR
HAS MOVED ACROSS THE LOCAL AREA LIMITING SIGNIFICANTLY THE CHANCES
FOR PRECIPITATION ACROSS THE LOCAL AREA. PW VALUES FINALLY WENT
BELOW 2.0 INCHES...WITH RECENT VALUES AROUND 1.6 INCHES. THE
MOISTURE WILL INCREASE SOMEWHAT STARTING LATE TONIGHT AND
MONDAY...AS A TROPICAL WAVE AFFECT THE LOCAL AREA. THIS WAVE IS
NOT IMPRESSIVE...AND WILL ONLY PRODUCE ISOLATED SHOWERS MAINLY
ACROSS THE EASTERN HALF OF PUERTO RICO...AND FEW SHOWERS OVER THE
U.S. VIRGIN ISLANDS. COMPUTER MODELS AGREE THE BEST MOISTURE WILL
AFFECT THE AREA MONDAY...AND BY MONDAY NIGHT...ANOTHER AREA OF
DRIER AIR WILL MOVE ACROSS THE LOCAL AREA BEHIND THE
WAVE...RETURNING TO A MORE DRIER SCENARIO THAN WE HAVE SEEN IN
RECENT DAYS. IN GENERAL...NO SIGNIFICANT WEATHER EVENTS ARE
FORECAST TO AFFECT THE LOCAL AREA IN THE SHORT TERM AT THIS TIME.
A HIGH PRESSURE SYSTEM AT MID TO UPPER LEVEL OF THE ATMOSPHERE IS
EXPECTED TO LINGER ACROSS THE NORTHEAST CARIBBEAN. THE ONLY
CONVECTION EXPECTED IS THE DIURNAL AFTERNOON CONVECTION ACROSS THE
WESTERN INTERIOR SECTION OF PUERTO RICO...AND FEW OVER THE U.S.
VIRGIN ISLANDS. MEANWHILE...IN THE LONG TERM...GFS COMPUTER MODEL
SUGGEST AN UPPER LEVEL LOW WILL APPROACH THE LOCAL AREA FROM THE
EAST AT THE END OF NEXT WEEK. HOWEVER...THE MODEL FORECAST IS THAT
THE UPPER LOW WILL STAY EAST OF THE ISLANDS...WITH SUBSIDENCE AIR
STAYING OVER THE AREA. ALSO...THE MODEL FORECAST A COLD FRONT
WILL APPROACH THE LOCAL AREA FROM THE NORTHWEST BY NEXT WEEKEND.
HOWEVER...IS TOO EARLY TO KNOW EXACTLY IF THIS SCENARIO WILL
OCCUR.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL ACROSS ALL TAF SITES
TONIGHT THROUGH MONDAY MORNING.

Good morning.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
457 AM AST MON OCT 11 2010

.SYNOPSIS...AT UPPER LEVELS...HIGH PRESSURE WILL PREVAIL OVER THE
CARIBBEAN SEA WHILE A CUT-OFF LOW SLOWLY APPROACHES THE WINDWARD
ISLANDS FROM THE EAST NORTHEAST DURING THE NEXT EIGHT DAYS.

AT MID LEVELS...HIGH PRESSURE STRETCHES FROM THE SOUTH CENTRAL
ATLANTIC OCEAN TO THE NORTHEAST CARIBBEAN WITH THIS GENERAL
PATTERN CONTINUING THROUGH SUNDAY.

AT LOWER LEVELS...A TROPICAL WAVE IS NOW MOVING THROUGH PUERTO
RICO AND WILL MOVE INTO THE DOMINICAN REPUBLIC LATER THIS
AFTERNOON. HIGH PRESSURE IN THE CENTRAL ATLANTIC JUST NORTH OF 20
DEGREES NORTH LATITUDE WILL MAINTAIN EASTERLY FLOW OVER THE LOCAL
AREA THAT WILL CONTAIN PATCHES OF MOISTURE AND SHOWERS. NEXT WEEK
A COLD FRONT WILL APPROACH 20 DEGREES NORTH TO THE NORTH OF THE
LOCAL AREA AND HIGH PRESSURE WILL BUILD OVER THE WESTERN ATLANTIC.

&&

.DISCUSSION...SCATTERED SHOWERS HAVE MOVED ACROSS SOUTHEAST AND
SOUTH PUERTO RICO CONTINUOUSLY SINCE BEFORE MIDNIGHT AS A TROPICAL
WAVE MOVES THROUGH THE AREA. THESE SHOWERS SHOULD BEGIN TO
DIMINISH THIS MORNING. LINGERING MOISTURE OVER NORTHWEST PUERTO
RICO AND SOUTH SOUTHEAST FLOW BEHIND THE WAVE THIS AFTERNOON WILL
SPAWN SHOWERS AND THUNDERSTORMS OVER THE AREA AND OVER THE
NORTHERN COASTAL PLAINS AND INTERIOR MOUNTAINS BEFORE DRIER AIR
MOVES IN TONIGHT. BOTH THE GFS AND THE ECMWF INDICATE A GENERAL EAST
SOUTHEAST FLOW OUT OF A SURFACE HIGH PRESSURE LOW IN THE SUB-
TROPICAL ATLANTIC THAT WILL CONTINUE FOR THE REST OF THE WEEK.
THIS BRINGS PATCHES OF MOISTURE ACROSS THE AREA THAT WILL BRING
SCATTERED PASSING SHOWERS ACROSS EASTERN PUERTO RICO AND THE U.S.
VIRGIN ISLANDS DURING THE EARLY MORNING HOURS...AND AFTERNOON
THUNDERSTORMS TO THE WESTERN HALF OF PUERTO RICO EACH DAY.
MOISTURE IS NOT EXPECTED TO BE SUFFICIENT TO BRING ANYTHING MORE
THAN OCCASIONAL AND VERY LOCALIZED URBAN AND SMALL STREAM FLOODING
DURING THE AFTERNOONS IN THE HEAVIEST OF SHOWERS. THE FRONT OUT OF
THE UNITED STATES THAT REACHES ITS CLOSEST POINT TO PUERTO RICO
SOMETIME DURING THE MIDDLE OF NEXT WEEK MAY BRING MORE SHOWERS TO
THE AREA AS MOIST FLOW CONVERGES TO THE SOUTH OF THE BOUNDARY OVER
US...BUT THE FRONT APPEARS TO COME NO CLOSER THAN 20 DEGREES NORTH
AND MID LEVELS ARE RELATIVELY DRY JUST AS THEY WILL BE FOR MOST
OF THIS WEEK AND NEXT AFTER THE TROPICAL WAVE PASSES OUT OF OUR
AREA.

&&

.AVIATION...
VFR WILL PREVAIL ACROSS ALL OF THE TAF SITE THROUGH THE FORECAST
PERIOD WITH THE FOLLOWING EXCEPTIONS...BRIEF MVFR CONDS POSSIBLE
ACROSS TJPS AND TISX IN PASSING SHRA THROUGH THE MORNING HOURS.
AFT 11/17Z...SHRAS AND ISOLD TSTMS COULD PRODUCE PERIODS OF
MVFR/IFR CONDS AND MOUNTAIN OBSCURATIONS ACROSS TJBQ...TJMZ...AND
POSSIBLY TJSJ. LLVL WINDS WILL BE MAINLY FROM THE SE AT 10 TO 15
KTS.

&&

.MARINE...SEAS ARE EXPECTED TO REMAIN 3 TO 4 FEET OR LESS
THROUGHOUT THE FORECAST PERIOD IN THE SURROUNDING WATERS. WINDS
WILL ALSO BE GENERALLY ONLY LIGHT TO MODERATE.

&&
