GREEN ALERT IN EL SALVADOR BECAUSE OF THE RAINS

Yesterday was the rainiest day on El Salvador since October 18 2011 when we were under the heavy rains from TD 12E. Unfortunately yesterday we had the first victim of the rainy season when a person was killed by a lightning. The heavy rains will continue today and on the weekend so the government declared green alert. This is the rainfall registered yesterday in some stations:

Suchitoto 67 mm/2.64 inches
San Salvador 73 mm/2.87 inches
Acajutla 75 mm/2.95 inches
Zacatecoluca 102 mm/4.02 inches
Santa Tecla 123.6 mm/4.87 inches Highest rainfall registered yesterday

In Santa Tecla the average rainfall for May is 160 mm/6.30 inches, that means that 77% of the average monthly amount fell in just one night. This map shows the distribution of yesterday rainfall:

.UPDATE...HAD AN ACTIVE LATE AFTERNOON AND EARLY EVENING...
ESPECIALLY ACROSS THE SAN JUAN METRO AREA...AS BANDS OF SHOWERS
AND EMBEDDED THUNDERSTORMS WITH VERY HEAVY RAIN AFFECTED AREAS
FROM SAN JUAN THROUGH GUAYNABO AND BAYAMON. NUMEROUS REPORTS OF
FLOODING...INCLUDING THE RIO PIEDRAS AND SEVERAL SECTIONS OF
GUAYNABO. EXPECT VARYING AMOUNTS OF CLOUDINESS...SCATTERED
SHOWERS AND AN ISOLATED THUNDERSTORM OR TWO ACROSS THE LOCAL
ISLANDS OVERNIGHT. INHERITED SHORT TERM GRIDS AND ZFP HAD A
PRETTY GOOD HANDLE ON EXPECTED CONDITIONS OVERNIGHT...BUT SENT A
QUICK UPDATE TO BOTH TO ALTER THE WEATHER...SKY COVER...POPS AND
WINDS IN SEVERAL ZONES. FOR THE COASTAL WATERS...MADE A COUPLE OF
SEMANTIC ALTERATIONS TO THE PREVIOUS CWF...OTHERWISE NO CHANGES.
SMALL BOAT OPERATORS SHOULD EXERCISE CAUTION ACROSS MOST OF THE
LOCAL COASTAL WATERS OVERNIGHT.

Good morning. Another round of showers is expected today for PR. But a drying trend will occur early next week.

.SYNOPSIS...BROAD AND ELONGATED MID TO UPPER LEVEL RIDGE EXTENDING
NORTH NORTHEAST ACROSS THE REGION INTO THE WEST CENTRAL ATLANTIC...
WILL CONTINUE TO BUILD AND SPREAD FURTHER NORTHEAST ACROSS
NORTHERN LEEWARDS THROUGH LATER TODAY. STRONG SURFACE HIGH
PRESSURE LOCATED ACROSS THE NORTH CENTRAL ATLANTIC AND EXTENDING
SOUTHEAST ACROSS THE NORTHERN LEEWARDS...WILL BUILD FURTHER SOUTH
INTO THE NORTHEASTERN CARIBBEAN OVER THE NEXT SEVERAL DAYS. THIS
WILL MAINTAIN A FAIRLY TIGHT PRESSURE GRADIENT ACROSS THE REGION

&&

.DISCUSSION...MOST OF THE SHOWERS DISSIPATED BEFORE MIDNIGHT WITH
A FEW SHOWERS MOVING ON SHORE AND AFFECTING THE EASTERN AND
SOUTHERN PORTIONS OF PUERTO RICO. THE SATELLITE AND RADAR IMAGES
ARE SHOWING AN AREA OF INCREASING LOW LEVEL MOISTURE OVER THE
LOCAL WATERS JUST EAST OF PUERTO RICO. THIS AREA OF LOW LEVEL
MOISTURE WILL INCREASE THE CHANCES OF SHOWERS ACROSS THE EASTERN
HALF AND SOUTHERN COAST OF PUERTO RICO THROUGH MID MORNING.

SIMILAR CONDITIONS TO YESTERDAY ARE EXPECTED TODAY...AS DIURNAL
HEATING AND THE AVAILABLE MOISTURE WILL COMBINE TO GENERATE
SHOWERS AND THUNDERSTORMS ALONG THE NORTHERN HALF PUERTO RICO THIS
AFTERNOON. THESE SHOWERS AND THUNDERSTORMS DEVELOPMENT WILL BE
ENHANCED BY THE CROSS VENTILATION AT MID TO UPPER LEVELS.

OVERALL MODELS SUGGEST A GRADUAL DECREASE IN THE AVAILABLE MOISTURE
ACROSS THE REGION FROM SUNDAY THROUGH WEDNESDAY. TRADE WINDS BECOME MORE
EASTERLY AND INCREASE BY EARLY NEXT WEEK.

&&

.AVIATION...PREVAILING VFR CONDITIONS WILL CONTINUE ACROSS THE LOCAL
ISLANDS AND AT ALL TAF SITES WITH BRIEF VCSH AND MVFR EXCEPTIONS
DURING THE PERIOD. LOCAL MOUNTAIN OBSCURATIONS IN ISOLATED TO
SCATTERED AND ISOLATED THUNDERSTORMS...ESPECIALLY BETWEEN 19/17Z AND
19/22Z. LLVL WINDS OVERNIGHT ARE GENERALLY E TO SE AT 5 TO 10 KTS.

Good Morning
Hope everyone stays relatively dry today.
The sun is shining here now but we awoke to a heavy rainstorm this morning.
The pool is overflowing again and the ground is supersaturated. My rain gauge showed about 1.75 inches of rain in a little over an hour.

Have a good day
Barbara

[cycloneye]

Hi Barbara. The Villas cam is not working at this time because of renovations to the place. But I have the other ones that you posted at the first post.

[msbee]

hi Luis
yes, I know that one is not working. the other one of the harbor works sometimes.
this one:
http://www.st-maarten-island-guide.com/ ... arborview/
I gave you that one didn't I?

and the other one at Sunset Beach Grill with the planes is also not working. They say they will soon have it back up and running.
I hope so

Hi Macrocane. TD TWO-E has formed well SW of El Salvador and the forecast is to make landfall on the Mexican Coast as a Hurricane. The good news for you over there is that this one wont go there,but the EPAC season is only starting and for sure many more will form and some may threat your country or get close. But we hope that nothing bad occurs if landfall occurs in the Mexican coast.

LEAST THE END OF THE WORK WEEK. AT LOW LEVELS...STRONG SURFACE HIGH
PRESSURE ANCHORED ACROSS THE NORTH CENTRAL ATLANTIC AND A BROAD
TROUGH SPREAD ACROSS THE WEST AND CENTRAL CARIBBEAN...WILL CONTINUE

WILL RESULT IN MOSTLY FAIR WEATHER SKIES FOR MUCH OF THE REGION.
FURTHER EAST OF THE REGION...A WEAK EASTERLY PERTURBATION INDUCED
BY THE LONG WAVE TROUGH ACROSS THE SUBTROPICAL ATLANTIC AND EAST
OF THE LESSER ANTILLES WILL CONTINUE WESTWARDS AND BRING SHALLOW
PATCHES OF LOW TO MID LEVEL CLOUDS AND SHOWERS TO THE REGION FROM
TIME TO TIME.

&&

.DISCUSSION...OVERALL MODEL GUIDANCE AND LATEST MIMIC/TPW SATELLITE
DERIVED PWAT SUGGEST A CONTINUED DRYING TREND OVER THE NEXT FEW
DAYS...ALTHOUGH DOMINANT EASTERLY TRADES WILL BRING SMALL PATCHES
OF LOW LEVEL MOISTURE ACROSS THE REGION. THIS LIMITED MOISTURE
ADVECTION WILL BE SUFFICIENT TO AID IN THE DEVELOPMENT SOME SHOWERS
AND A FEW THUNDERSTORMS ACROSS PARTS OF THE ISLANDS AND SURROUNDING
WATERS EACH DAY. HOWEVER...EXPECT THE PREVAILING STEERING FLOW TO
QUICKLY PUSH MUCH OF THE LOCALIZED CONVECTION QUICKLY ACROSS THE
ISLANDS LEAVING NO WIDESPREAD RAINFALL TODAY AND FOR THE NEXT
SEVERAL DAYS. ANY HEAVY DOWN BURST OF RAINFALL SHOULD BE VERY
LOCALIZED DURING THE REST OF THIS AFTERNOON AND WILL BE FOCUSED
MAINLY OVER THE WEST SECTIONS OF PUERTO RICO. LESSER ACTIVITY IS
EXPECTED ACROSS THE VIRGIN ISLANDS WHERE DRIER AIR HAS ALREADY
BEGUN TO FILTER IN FROM THE EAST. ONLY A FEW CONVECTIVE STREAMERS
WILL CONTINUE TO FORM ON THE LEE SIDE OF THE ISLANDS. ALL MODELS
SUGGEST THIS GRADUAL DRYING TREND TO CONTINUE THROUGH THE END OF
THE WORK WEEK...EXCEPT FOR THE ISOLATED TO SCATTERED CONVECTION IN
SOME AREAS ACROSS PUERTO RICO EACH AFTERNOON.

FURTHER DOWN THE ROAD...BY LATE SATURDAY OR SUNDAY AND INTO EARLY NEXT
WEEK...MODELS SUGGEST AN INCREASE IN MOISTURE ONCE AGAIN WITH BETTER
CHANCES FOR SHOWERS AND THUNDERSTORM DEVELOPMENT ACROSS THE REGION.
BY THEN THE SYNOPTIC PATTERN CHANGES...AS THE UPPER RIDGE IS FORECAST
TO SLOWLY ERODE WITH THE APPROACH OF A AMPLIFYING TROUGH ACROSS THE
WEST AND SOUTHWEST ATLANTIC. THIS WILL BE SUPPORTED BY A LOOSENING
OF THE SURFACE PRESSURE GRADIENT AND THUS ALLOW FOR BETTER LOCAL SEA
BREEZE CONVERGENCE ACROSS THE ISLANDS. UNTIL THEN...EXPECT MOSTLY
FAIR WEATHER SKIES EXCEPT FOR THE PERIODS OF NOCTURNAL SHOWERS

Hi my friends, just hearing our local radio looks like that a plane crashed in Dominica this afternoon. This news is not offcial but there's high confidence that this crash could be confirmed. I i have more i will keep your informed. Thus, fatalities have been reported ( non officially).

[Macrocane]

Yep, good news is it's not coming here, hopefully nothing bad will happen in Mexico either. The rains have continued in El Salvador but thankfully no more emergencies have been reported. In Honduras the news are not that good, the rains of the weekend damaged 106 homes in the country but no fatalities were reported.

Gusty we'll be waiting for the info :S

it was just a water spout
