Ok folks, test #3

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
606 AM AST MON JUL 19 2010

.SYNOPSIS...A TROPICAL WAVE LOCATED JUST EAST OF THE U.S. VIRGIN
ISLANDS EARLY THIS MORNING...WILL MOVE WEST NORTHWEST ACROSS THE
REMAINDER OF THE LOCAL AREA TODAY THROUGH TONIGHT AND THEN SLOWLY
AWAY FROM THE LOCAL REGION TUESDAY AND TUESDAY NIGHT.

&&

.DISCUSSION...FOR TODAY THROUGH TONIGHT AND TUESDAY...TROPICAL
WAVE AXIS APPEARS TO BE LOCATED JUST EAST OF THE U.S. VIRGIN
ISLANDS EARLY THIS MORNING...AND WILL MOVE WEST NORTHWEST ACROSS
THE REMAINDER OF THE LOCAL AREA TODAY THROUGH TONIGHT AND THEN
SLOWLY AWAY FROM THE LOCAL REGION TUESDAY AND TUESDAY NIGHT. THIS
WAVE AND ITS ASSOCIATED MOISTURE WILL INTERACT WITH LOCAL EFFECTS
AND YET AGAIN FAVORABLE UPPER LEVEL CONDITIONS...TO PRODUCE
ANOTHER ROUND OF ACTIVE WEATHER...WITH SHOWERS AND THUNDERSTORMS...
PERIODS OF HEAVY RAINFALL...LIGHTNING AND LOCALLY STRONG AND
GUSTY (SQUALLY) WINDS ACROSS THE LOCAL ISLANDS...TODAY THROUGH
TONIGHT AND TUESDAY. STILL EXPECT URBAN AND SMALL STREAM FLOODING
TO OCCUR WITH THIS WAVE PASSAGE AND THE POTENTIAL STILL EXISTS
FOR AT LEAST SOME LOCALIZED FLASH AND RIVER FLOODING...AND THIS
WILL CONTINUE TO BE CLOSELY MONITORED. ALTHOUGH EXPECT SIGNIFICANT
DEVELOPMENT OF SHOWERS AND THUNDERSTORMS LOCALLY TODAY...GIVEN
SOMEWHAT DISORGANIZED AND SPOTTY RADAR APPEARANCE AT THIS TIME...
OPTED TO HOLD OFF ON A FLASH FLOOD WATCH. IN ADDITION...BANDS
AND LINES OF THUNDERSTORMS COULD AGAIN DEVELOP...RESULTING IN
SOME STRONG AND POTENTIALLY DAMAGING WIND GUSTS.

LOOKING AHEAD...MOISTURE STILL APPEARS TO LINGER THROUGH LATE
TUESDAY NIGHT/EARLY WEDNESDAY...WITH A BRIEF "DRIER" BREAK
POSSIBLE DURING WEDNESDAY...FOLLOWED BY ANOTHER SURGE OF MOISTURE
LATE WEDNESDAY AND WEDNESDAY NIGHT THROUGH MOST OF THURSDAY...WITH
A SECOND "DRIER" BREAK INDICATED AGAIN FOR THURSDAY NIGHT AND
FRIDAY.

&&

.AVIATION...TROPICAL WAVE AXIS IS OVER ANEGADA PASSAGE (JUST EAST
OF USVI) AND MOVING WEST NORTHWEST. IT WILL GIVE REGION ANOTHER
DAY OF SHOWERS/THUNDER. HAVE TIMED MOST LIKELY TIMES OF CONVECTION
IN TAFS ACCORDING TO PROXIMITY OF THE WAVE AND LOCATION OF BEST
700-500 MB VORTICITY ADVECTION ACCORDING TO NAM AND GFS MODELS.
THIS LEVEL SEEMED TO WORK PRETTY WELL FOR WHERE CONVECTION
OCCURRED ON SUNDAY. MIGHT EVEN NEED TO INCREASE MENTION OF SHOWERS
IN MOST 12Z TAFS SINCE THERE ARE SO MANY PASSING OVER THE
SURROUNDING WATERS ALREADY. MVFR EXPECTED IN SHOWERS WHILE
MOUNTAIN OBSCURATIONS WILL BE COMMON.

&&

.MARINE...GENERALLY EXPECT WINDS OF 13 TO 21 KNOTS AND SEAS OF 4
TO 9 FEET ACROSS THE REGIONAL WATERS THROUGH WEDNESDAY. A SMALL
CRAFT ADVISORY IS IN EFFECT FOR MOST OF THE LOCAL COASTAL WATERS
TODAY AND SMALL BOAT OPERATORS SHOULD EXERCISE CAUTION ACROSS THE
REMAINDER OF THE WATERS. PLEASE REFER TO SJUCWFSJU FOR THE LATEST
FORECAST DETAILS AND SMALL CRAFT ADVISORY DELINEATION.

.SITE SUPPORT...THE XXI CENTRAL AMERICAN AND CARIBBEAN SPORT
GAMES MAYAGUEZ 2010 ARE UNDER WAY AND A SPECTACULAR OPENING
CEREMONY WAS DELIVERED LATE SUNDAY AFTERNOON AND EARLY SUNDAY
EVENING. THE GAMES WILL CONTINUE THROUGH SUNDAY AUGUST 1. WFO SAN
JUAN WILL CONTINUE PROVIDING ON SITE AND IN OFFICE TEAM SUPPORT TO
THE PUERTO RICO EMERGENCY MANAGEMENT AGENCY (PREMA) AND OTHER
FEDERAL AGENCIES THROUGHOUT THIS EVENT. TEAM MEMBERS REMAIN ON
SITE IN MAYAGUEZ AND AT THE WFO AND DAILY BRIEFINGS FOR EMERGENCY
MANAGEMENT OFFICIALS WILL CONTINUE TODAY AT 9 AM.

THE WEATHER FOR TODAY AND TONIGHT THROUGH TUESDAY LOOKS RATHER
UNSETTLED ACROSS MOST OF THE GAME SITES...AS THE TROPICAL WAVE
MOVES SLOWLY ACROSS THE LOCAL AREA. THE TODAY WILL BEGIN WITH A
MIXTURE OF CLOUDINESS AND SUNSHINE WITH SCATTERED SHOWERS AND
POSSIBLY A THUNDERSTORM OR TWO. HOWEVER...AS DEEPER MOISTURE
CONTINUES TO SPREAD ACROSS THE LOCAL ISLANDS...SHOWERS AND
THUNDERSTORMS WILL BECOME MORE PREVALENT AS THE DAY PROGRESSES...
WITH SOME MOVING INTO SOUTH AND EAST SECTIONS OF PUERTO RICO...
WHILE OTHER SHOWERS AND STORMS DEVELOP OVER THE CENTRAL AND
WESTERN INTERIOR AND WEST SECTIONS OF THE ISLAND. THESE SHOWERS
AND THUNDERSTORMS WILL LINGER INTO TONIGHT...WITH ADDITIONAL
ACTIVE WEATHER EXPECTED TUESDAY. THE POTENTIAL EXISTS FOR
FREQUENT LIGHTNING...HEAVY RAIN...BRIEF WIND GUSTS AND SOME MINOR
LOW LYING FLOODING AND PONDING OF WATER ON ROADWAYS.
