355 PM AST FRI JUL 22 2011

.SYNOPSIS...AN ACTIVE TROPICAL WAVE WILL CONTINUE TO APPROACH THE
LESSER ANTILLES THE REST OF THIS AFTERNOON THROUGH TONIGHT...THEN
MOVE ACROSS THE LOCAL AREA SATURDAY THROUGH SUNDAY. THIS FEATURE
AND ITS ASSOCIATED MOISTURE WILL COMBINE WITH INCREASINGLY
FAVORABLE UPPER LEVEL CONDITIONS AND LOCAL EFFECTS...TO RESULT IN
CLUSTERS AND BANDS OF SHOWERS AND THUNDERSTORMS ACROSS THE LOCAL
ISLANDS.

&&

.DISCUSSION...MOISTURE ALREADY SPREADING ACROSS THE FA AT THIS
TIME AND EXPECT THIS TREND OF INCREASING DEEP TROPICAL MOISTURE
AND INSTABILITY TO CONTINUE THROUGH TONIGHT AND SATURDAY AS
TROPICAL WAVE APPROACHES AND THEN PASSES LATER SATURDAY THROUGH
SUNDAY. FOR TONIGHT...INITIALLY MOISTURE APPEARS TO BE ASSOCIATED
WITH INVERTED UPPER LEVEL TROUGH AND ITS REFLECTION BUT DO NOT
EXPECT MUCH OF A BREAK BETWEEN THIS FEATURE AND MOISTURE
ASSOCIATED WITH TROPICAL WAVE. BASED ON SATELLITE...TROPICAL WAVE
CONTINUES TO SLOWLY BECOME A BIT MORE ORGANIZED AND EXPECT THIS
TREND TO CONTINUE GIVEN VERY WARM WATER AND FAVORABLE UPPER LEVEL
CONDITIONS. THUS...EXPECT THESE TWO FEATURES AND INCREASING
MOISTURE AND INSTABILITY TO COMBINE WITH FAVORABLE MID TO UPPER
LEVEL CONDITIONS AND LOCAL EFFECTS...TO PRODUCE A SIGNIFICANT
AMOUNT OF CLOUDINESS...SHOWERS AND THUNDERSTORMS ACROSS THE LOCAL
ISLANDS. EXPECT THESE SHOWERS AND STORMS TO LINE UP IN BANDS AND
CLUSTERS...AND LATE TONIGHT THROUGH SATURDAY OR EARLY SATURDAY
NIGHT...SHOULD BECOME QUITE ACTIVE...WITH PERIODS OF HEAVY
RAINFALL...LOCALLY STRONG WIND GUSTS...LIGHTNING AND AT LEAST SOME
MINOR LOW LYING FLOODING. DID NOT FEEL CONFIDENT ENOUGH THAT
DECENT MCS WOULD DEVELOP OVER THE LAND MASS AND DECIDED TO LEAVE
FLASH FLOOD WATCH OUT AT THIS TIME. HOWEVER...SHOULD FURTHER
DEVELOPMENT OF TROPICAL WAVE TAKE PLACE OR BANDS AND CLUSTERS
BECOME TOO FREQUENT...LATER SHIFTS WILL NEED TO CONSIDER THIS.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL ACROSS THE LOCAL ISLANDS
AND MOST TAF SITES THROUGH EARLY THIS EVENING...BUT WITH
INCREASING MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURATIONS IN
BANDS AND CLUSTERS OF SHOWERS AND THUNDERSTORMS. BY LATER THIS
EVENING AND THROUGH SATURDAY...EXPECT FAIRLY FREQUENT MVFR
CONDITIONS...WITH EMBEDDED IFR CONDITIONS...IN SCATTERED TO
NUMEROUS SHOWERS AND ISOLATED THUNDERSTORMS. VISIBILITIES MAY
OCCASIONALLY LOWER TO 1 MILE OR LESS IN HEAVY RAINFALL...WITH
SURFACE WIND GUSTS OF 30 TO 35 KNOTS AND CONVECTIVELY INDUCED LOW
LEVEL WIND SHEAR POSSIBLE.

&&

.MARINE...AFOREMENTIONED TROPICAL WAVE WILL CONTINUE TO APPROACH
THE LESSER ANTILLES THE REST OF THIS AFTERNOON THROUGH
TONIGHT...THEN MOVE ACROSS THE LOCAL AREA SATURDAY THROUGH SUNDAY.
THIS FEATURE AND ITS ASSOCIATED MOISTURE WILL RESULT IN CLUSTERS
AND BANDS OF SHOWERS AND THUNDERSTORMS ACROSS THE REGIONAL
WATERS...WITH LOCALLY GUSTY WINDS...LIGHTNING...HEAVY RAIN AND
CHOPPY SEAS. WILL CONTINUE TO MONITOR THIS SITUATION CLOSELY...AS
MAY END UP NEAR SMALL CRAFT ADVISORY CONDITIONS FOR PARTS OF THE

[knotimpaired]

Vieques here. We have been blessed and have not had rain yet. By looking at the radar it appears MJ and Ms Bee had some earlier.

I am an early to bed, early to rise person so I will hit the sack at about 8 but I will take my iPad upstairs and report if and when it wakes me up. It will be easy, we have a tin roof.

PS. We live in a house that was built as a drive under (no longer that way) so we have to walk outside and up the stairs to get to the BR. This explains reports from upstairs. I have no desire to walk out in squally weather to come down to the PC

[cycloneye]

Up to 30%. knotimpaired,stay safe there and when you can,post observations from there.

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 PM EDT FRI JUL 22 2011

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
STORM CINDY...LOCATED ABOUT 590 MILES NORTH-NORTHWEST OF THE AZORES.

A WELL-DEFINED TROPICAL WAVE LOCATED ABOUT 200 MILES EAST OF THE
LESSER ANTILLES IS PRODUCING DISORGANIZED SHOWERS AND
THUNDERSTORMS. SOME SLOW DEVELOPMENT OF THIS SYSTEM IS POSSIBLE
DURING THE NEXT COUPLE OF DAYS AS IT MOVES WESTWARD TO
WEST-NORTHWESTWARD AT 15 TO 20 MPH. THERE IS A MEDIUM CHANCE...30
PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS. REGARDLESS OF DEVELOPMENT...BRIEF PERIODS OF LOCALLY
HEAVY RAINFALL AND GUSTY WINDS WILL OCCUR OVER PORTIONS OF THE
LESSER ANTILLES TONIGHT AND TOMORROW MORNING.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.

[Macrocane]

Heavy rains and thunderstorms have been registered in the last few hours in El Salvador, some of the accumulations:

UCA (in Antiguo Cuscatlan where I live and just west of San Salvador) 35 mm/1.38 inches from 6 pm to 8 pm
San Salvador 30 mm/1.18 inches (6 pm to 8 pm)
Santa Ana 20 mm/0.79 inches (7 pm to 8 pm)
Zacatecoluca 48 mm/1.89 inches (7 pm to 8 pm)

The rains continue at this time in El Salvador there have been some minor floods, fallen trees, and a few mudslides, in the other hand it was a great relief for the warmer than normal temps that were registered today in the country.

WERE DETECTED THIS EVENING ACROSS THE EASTERN HALF OF PUERTO
RICO...VIEQUES...CULEBRA...THE U.S. VIRGIN ISLANDS AS WELL AS ACROSS
THE COASTAL WATERS. THIS ACTIVITY WAS ASSOCIATED WITH THE MOISTURE
OF AN UPPER LEVEL TROUGH AND ITS ASSOCIATED SURFACE REFLECTION.
LATEST SATELLITE IMAGES THIS EVENING INDICATED A LARGE AREA OF
CLOUDINESS...EXTENDING FROM THE LOCAL ISLANDS EAST SOUTHEAST ACROSS
THE LEEWARD AND WINDWARD ISLANDS AND ACROSS THE TROPICAL ATLANTIC
FOR SEVERAL HUNDRED MILES. A TROPICAL WAVE IS EXPECTED TO REACH THE
EASTERN CARIBBEAN TONIGHT...MOVING THEN ACROSS THE LOCAL ISLANDS

Hi folks, I love this Caribbean thread.
Always know when something's brewing. the weather here today was perfect.
Now all I need to see are the clouds heading W to E, or in this case, to my NE.
I really wasn;t expecting to see such a Southerly drop on 90L.
For those in the direct line of fire, keep us posted.

[Macrocane]

It was a quiet night here in Vieques.

Yesterday we received .12" for the day. The thunder woke us up at about 10 minutes ago and there is quite a bit of a light show going on to the north of us but so far today we have only gotten .04"

.SYNOPSIS...AN ACTIVE TROPICAL WAVE NOW LOCATED OVER THE LESSER
ANTILLES WILL CONTINUE TO APPROACH THE LOCAL FORECAST AREA THIS
AFTERNOON THROUGH TONIGHT...THEN MOVE ACROSS THE LOCAL AREA
SATURDAY THROUGH SUNDAY. THIS FEATURE AND ITS ASSOCIATED MOISTURE
WILL COMBINE WITH INCREASINGLY FAVORABLE UPPER LEVEL CONDITIONS
AND LOCAL EFFECTS...TO RESULT IN STRONG THUNDERSTORMS AND HEAVY
SHOWERS IN THE FORM OF SQUALL LINES.


&&

.DISCUSSION...SQUALLS CONTINUED TO MOVE ACROSS THE LOCAL FORECAST
AREA THROUGH THE OVERNIGHT HOURS GENERATING GUSTY WINDS AND HEAVY SHOWERS.
ACTUAL REPORTS AND RADAR ESTIMATES SHOWED GUSTY WINDS OF +40 MPH GUSTS
AS SQUALLS MOVED ACROSS THE U.S. VIRGIN ISLANDS...CULEBRA...VIEQUES
AND EASTERN PORTIONS OF PUERTO RICO.

MOISTURE ASSOCIATED TO THE LEADING EDGE INTERACTED WITH FAVORABLE
UPPER LEVEL CONDITIONS AND GENERATED SQUALLY CONDITIONS ACROSS THE
LOCAL FORECAST AREA. AT THE MOMENT THESE SHOWERS HAVE NOT GENERATED
LARGE AMOUNTS OF RAINFALL ACCUMULATION DUE TO THE FAST MOVING CHARACTERISTICS
OF THESE SHOWERS. USGS SENSOR REPORTED QUEBRADA MARIN IN PATILLAS OUT
OF ITS BANKS EARLIER TONIGHT WITH RAINFALL ACCUMULATIONS OF LESS THAN
AN INCH ACROSS THE SOUTHEAST PORTIONS OF PUERTO RICO...THIS SHOWS HOW
SATURATED IS THE EASTERN PORTIONS OF PUERTO RICO DUE TO RAINFALL ACTIVITY
IN THE PAST FEW DAYS. THE TROPICAL WAVE IS NOW LOCATED OVER THE LESSER
ANTILLES AND MODELS SUGGEST THE BULK OF MOISTURE ASSOCIATED TO THIS
WAVE ARRIVING THE LOCAL FORECAST AREA LATER TODAY...THEREFORE MAINTAINING
THE POTENTIAL FOR SMALL STREAM AND URBAN FLOODING TO OCCUR HIGH
THROUGH AT LEAST SUNDAY. A FLOOD WATCH COULD BE ISSUED LATER TODAY.

THE NATIONAL HURRICANE CENTER EXPECT SOME SLOW DEVELOPMENT OF THIS
TROPICAL WAVE DURING THE NEXT COUPLE OF DAYS AS IT MOVES WESTWARD
TO WEST-NORTHWESTWARD AT 15 TO 20 MPH. THIS DISTURBANCE HAS A
MEDIUM CHANCE...30 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING

LEVEL TROUGH ACROSS THE REGION AND A TROPICAL WAVE ACROSS THE
EASTERN CARIBBEAN...WILL COMBINE WITH FAVORABLE MID TO UPPER
LEVEL DYNAMICS AND LOCAL ISLANDS EFFECTS THROUGH AT LEAST
SUNDAY AFTERNOON...TO PRODUCE A SIGNIFICANT AMOUNT OF
CLOUDINESS...SHOWERS AND THUNDERSTORMS ACROSS THE REGION.

EXPECT THESE SHOWERS AND STORMS TO LINE UP IN BANDS AND CLUSTERS
BEGINNING SATURDAY AFTERNOON AND CONTINUING INTO SUNDAY TO
PRODUCE AN ACTIVE PERIOD OF WEATHER...WITH PERIODS OF HEAVY
RAINFALL...LOCALLY STRONG WIND GUSTS...LIGHTNING AND FLOODING.
URBAN AND SMALL STREAM FLOODING AND RAPID RIVER RISES ON MAINSTEM
RIVERS AND GUTS ARE POSSIBLE ACROSS THE LOCAL ISLANDS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A FLASH FLOOD WATCH MEANS THAT CONDITIONS ARE FAVORABLE FOR HEAVY
RAIN ACROSS THE WATCH AREA...WHICH MAY LEAD TO FLOODING. IF YOU
ARE IN THE WATCH AREA...CHECK YOUR PREPAREDNESS REQUIREMENTS...
ESPECIALLY IF YOU HAVE INTERESTS ALONG AREA RIVERS. KEEP
INFORMED...AND BE READY FOR QUICK ACTION IF FLOODING IS OBSERVED
OR IF A FLASH FLOOD WARNING IS ISSUED.

PEOPLE IN THE WATCH AREA SHOULD CONTINUE TO BE AWARE OF THE
POSSIBILITY FOR HEAVY RAINFALL. AVOID LOW LYING AREAS...AND BE
CAREFUL WHEN APPROACHING HIGHWAY DIPS AND UNDERPASSES. THE
HEAVY RAIN COULD ALSO CAUSE MUDSLIDES IN AREAS OF STEEP TERRAIN.
