AREA FORECAST DISCUSSION

314 PM AST TUE APR 13 2010
.SYNOPSIS...AT UPPER LEVELS...AN EAST-WEST 100-120 KNOT JET CORE
REMAINS 4 TO 6 DEGREES OF LATITUDE NORTH OF THE LOCAL AREA BUT IS
STILL PROVIDING GOOD VENTILATION FOR THE LOCAL AREA. THE JET WILL
ARCH NORTH BEGINNING SATURDAY AS A MID LATITUDE TROUGH DIGS INTO
THE WESTERN CARIBBEAN AND WILL RETURN ONCE THE TROUGH PASSES TO
THE EAST ON TUESDAY. ANOTHER TROUGH WILL PASS NORTH OF THE AREA ON
FRIDAY OF NEXT WEEK.
AT MID LEVELS... HIGH PRESSURE REMAINS OVER THE TROPICAL ATLANTIC
AND THE SOUTHERN CARIBBEAN THROUGH TUESDAY OF NEXT WEEK. PASSING
LOWS AND TROUGHS DOMINATE THE CANADIAN ATLANTIC AND EXTEND TOWARD
THE LOCAL AREA.
AT LOWER LEVELS...MOISTURE IS ARCHED OVER THE AREA ALONG THE
STREAMLINES IN A TROUGH WHOSE AXIS IS CENTERED NEAR IF NOT OVER
PUERTO RICO. LOW PRESSURE IS EXPECTED TO DEVELOP NORTH OF PUERTO
RICO ALTHOUGH CYCLOGENESIS IS NOT YET APPARENT. LOW PRESSURE
DRIFTS EAST WEDNESDAY AND THURSDAY...WHILE HIGH PRESSURE SINKS
SOUTH OVER SOUTH CAROLINA AND RIDGES EAST OVER THE ATLANTIC WATERS
TO OUR NORTH. HIGH PRESSURE WILL CONTINUE THROUGH EARLY NEXT
WEEK...BUT TROUGHING RE-DEVELOPS JUST NORTHWEST OF THE AREA NEXT
TUESDAY AND MOVES EAST OVER THE AREA TUESDAY NIGHT.
&&
.DISCUSSION...TROUGHING IS SLOWLY DEVELOPING ALONG A BROAD NORTH
SOUTH AXIS OVER THE AREA AND MOISTURE IS DEEPENING. RADAR TOPS
HAVE BEEN GENERALLY UNDER 40 THOUSAND FEET...BUT RAIN AMOUNTS IN
SOME AREAS HAVE EXCEEDED ONE TO TWO INCHES. WET CONDITIONS WILL
CONTINUE BUT WETTEST AREAS WILL BE DIFFICULT TO DETERMINE MUCH
AHEAD OF TIME DUE TO THE AMBIGUITY IN THE MODELS` LOCATION OF THE
LOW OR LOWS THAT ARE SUPPOSED TO FORM IN THE VICINITY AND MOVE
EAST LATER. HAVE FELT THAT THE GFS IS THE MOST CONSISTENT MODEL
AND HAVE USED WINDS FROM THAT MODEL THROUGHOUT MASSAGING THE POPS
TO FIT THE MOISTURE AND WINDS EXPECTED AND ASSUMING THAT MIDDAY
SEA BREEZES WILL DOMINATE THE SYNOPTIC FLOW. THE GFS HAS BEEN
HINTING AT VERY GOOD DIVERGENCE ALOFT WEDNESDAY WITH A PLUS 6 AT
14/18Z...SO NUMEROUS SHOWERS WITH A POSSIBLE SEA BREEZE SEEMS
REASONABLE FOR THE NORTH COAST. OTHERWISE FORECAST LATER IN THE
WEEK IS BASED ON GFS AND CONFIDENCE IS MEDIUM-LOW CONSIDERING THE
DISCREPANCIES IN MOISTURE AND WIND FIELDS. ONCE LOWS DO OR DO NOT
DEVELOP SHOULD BE ABLE TO ASCERTAIN CONDITIONS MORE PRECISELY.
NEVERTHELESS MJO IS ENTERING A WET PHASE AND MOISTURE WILL BE
PRESENT WITH OR WITHOUT CYCLOGENESIS SO THE CHANCES OF URBAN AND
SMALL STREAM FLOODING OR MAIN STEM RIVER FLOODING THIS WEEK ARE
ELEVATED.

MOSTLY VFR CONDS EXPECTED AT ALL TAF SITES FOR THE NEXT
12 HOURS...HOWEVER MVFR CONDITIONS AND LOCAL MOUNTAIN OBSCURATIONS ARE
POSSIBLE MAINLY OVER THE CENTRAL...WESTERN INTERIOR...AND WEST

ALSO VCSH OR PASSING SHRA EXPECTED ACROSS TNCM AND TKPK RESULTING
IN BRIEF PERIODS OF MVFR.

OF SOUTH AMERICA...AND ATLANTIC OCEAN TO THE AFRICAN COAST
FROM THE EQUATOR TO 32N. THE FOLLOWING INFORMATION IS BASED
ON SATELLITE IMAGERY...METEOROLOGICAL ANALYSIS...WEATHER
OBSERVATIONS...AND RADAR.
BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY
THROUGH 1645 UTC...
...THE ITCZ...
THE ITCZ AXIS IS CENTERED FROM LIBERIA NEAR 6N9W ALONG 3N20W
2N30W 3N40W INTO NE SOUTH AMERICA NEAR 5N52W. SCATTERED
MODERATE/STRONG CONVECTION IS FROM 1N-5N BETWEEN 12W-19W.
SCATTERED MODERATE/ISOLATED STRONG CONVECTION IS FROM EQ-5N

DISCUSSION...
THE GULF OF MEXICO...
A SURFACE TROUGH LINES THE MEXICO COAST IN THE WRN BAY OF
CAMPECHE ALONG 23N96W TO 18N94W. AN UPPER LEVEL SHORTWAVE TROUGH
EXTENDING FROM LOUISIANA TO ERN MEXICO IS SUPPORTING THE SURFACE
TROUGH AS WELL A LARGE AREA OF SHOWER ACTIVITY. SCATTERED
SHOWERS/ISOLATED THUNDERSTORMS COVER THE BAY OF CAMPECHE AND THE
SRN PORTION OF TEXAS S OF 28N W OF 89W. THE MAJORITY OF THE
THUNDERSTORMS ARE CONCENTRATED NEAR THE SURFACE TROUGH. A
SURFACE RIDGE BUILDS ACROSS THE ERN AND NRN GULF PROVIDING
GENERALLY FAIR WEATHER ACROSS MUCH OF THE GULF COAST STATES.
HOWEVER...WINDS UP TO 20 KT ARE IMPACTING MUCH OF THE BASIN

MONA PASSAGE ALONG 21N66W TO 17N68W. MOST OF THE SHOWER ACTIVITY
IS NORTH OF THE CARIBBEAN ISLANDS. HOWEVER...ISOLATED SHOWERS
STILL REMAIN WITHIN 90 NM EITHER SIDE OF THE AXIS ACROSS
PORTIONS OF HISPANIOLA AND PUERTO RICO. A SURFACE TROUGH E OF
THE LESSER ANTILLES IS PRODUCING SCATTERED SHOWERS WHICH ARE NOW

We continue to have juicy amounts of water in Guadeloupe. Meteo-France have just reported 47 millimeters of water (in 6 hours) at La Désirade, 26 at Sainte Anne, 20 at Sainte Rose! The yellow alert is always on effect until tommorow 8 AM, the Northern Leewards too but til 12 AM given our Pro mets of Meteo-France Guadeloupe. Here are some measurements in the Northern Leewards: 15,5 at Grand Case in 6 hours today and 3.4 at Gustavia. Looking outside of my window, another round of showers is coming. The sky is becoming darker and darker, the atmosphere is very moist...

Rain Rain Rain in the zone ...from correspondants of the Carib:
Plenty of Water Today.
By Jackie Fullbrook <fullbrookt at gmail.com>
Date: Tue, 13 Apr 2010 11:27:25 -0400
- - Dominica - -
Good morning everyone,
Had a absolutely beautiful morning yesterday, and another one today.
RAIN, RAIN, and more RAIN.
The water barrel is now full again. All the plants have had a nice wash and
drink. There are still some thick grey clouds up above, so hopefully a little
more water is on it's way. A nice breeze helping to cool things down a bit.
Sea reflecting the sky, pretty grey.
The neighbours new gully has been put under pressure, and seems to
be working. Much to her delight. Previously, poor woman ended up ankle deep
in water in her garden after a good downpour.
Downside, Arhggg MOZZIE EXPLOSION. And the weeds grow quicker
than the plants. Ahh well, all part of the price.
Sun is making feeble attempts to break through now. Could end up like
yesterday with a hot afternoon.
I'm off for another coffee. Check out that very grey view. You all take care.
and have a great day. Watch out for those mud slides.
P.S. More water falling.

- Applause for RAIN, remember HAITI

Good Morning,
Listening to the tapping on the roof and the slow drip drip into the cistern
has been much missed lately in St. Thomas. Over the last few days we've had a 1/4"
here and there, and this morning since dawn we've had at least another 1/2" of rain.
The map shows more coming and the trees are reaching for it. The birds are bathing
wildly.
The rains lift us up in the Virgin Islands, but create a potential tragedy for those

Go to http://www.usvihaitianrelief.org , join us in our efforts. If you are in St Thomas stop
by on Tuesday afternoons from 2-4pm for a dance (DJ "Royal" Janet Reiter) and a drink
and make a contribution, we'll be at Jumbies BBQ Joint on the Crown Bay Dock hosting
the largest cruise ship in the world, Royal Caribbean's OASIS of the Seas. The Oasis
calls on Labadee, Haiti every week and on St Thomas every Tuesday. Gathering at
Jumbies is an effort to remind the thousands of guests and residents here that Haiti's

The ripening tomatoes are making for great BLTs, and new lettuces are up, the herb garden

please.
We are the lucky ones for sure.

...from correspondants of the Carib:Plenty of Water Today.
By Jackie Fullbrook <fullbrookt at gmail.com>
Date: Tue, 13 Apr 2010 11:27:25 -0400
- - Dominica - -Good morning everyone,
Had a absolutely beautiful morning yesterday, and another one today.
RAIN, RAIN, and more RAIN.
The water barrel is now full again. All the plants have had a nice wash and
drink. There are still some thick grey clouds up above, so hopefully a little
more water is on it's way. A nice breeze helping to cool things down a bit.
Sea reflecting the sky, pretty grey.
The neighbours new gully has been put under pressure, and seems to
be working. Much to her delight. Previously, poor woman ended up ankle deep
in water in her garden after a good downpour.
Downside, Arhggg MOZZIE EXPLOSION. And the weeds grow quicker
than the plants. Ahh well, all part of the price.
Sun is making feeble attempts to break through now. Could end up like
yesterday with a hot afternoon.
I'm off for another coffee. Check out that very grey view. You all take care.
and have a great day. Watch out for those mud slides.
P.S. More water falling.
- RAIN - FINALLY!

Good Morning,
Listening to the tapping on the roof and the slow drip drip into the cistern
has been much missed lately in St. Thomas. Over the last few days we've had a 1/4"
here and there, and this morning since dawn we've had at least another 1/2" of rain.
The map shows more coming and the trees are reaching for it. The birds are bathing
wildly.
The rains lift us up in the Virgin Islands, but create a potential tragedy for those
homeless in Haiti. We must never forget the struggle that the surviving Haitians go
thru everyday to meet basic needs.

Big thunderstorm cells affecting parts of Puerto Rico.One of those is sinking southward towards San Juan (Where I am) Lets see if it weakens or takes another direction.

Re: Caribbean - CA=Flood Watches & Warnings for parts of PR
Updated discussion by NWS San Juan
I got in San Juan the big thunderstorm that was in the water to the north of the city.It moved southward and it was really nasty,with loud thunder,gusty winds and a heavy shower that lasted a half an hour.Its over now but there may be more in the overnight hours.But eastern Puerto Rico has been the area most affected by this event.

I got in San Juan the big thunderstorm that was in the water to the north of the city.It moved southward and it was really nasty,with loud thunder,gusty winds and a heavy shower that lasted a half an hour.Its over now but there may be more in the overnight hours.But eastern Puerto Rico has been the area most affected by this event.
