AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JUAN PR 1252 PM AST SUN DEC 2 2007 .UPDATE...SCATTERED TO NUMEROUS SHOWERS AND FEW THUNDERSTORMS WILL CONTINUE TO AFFECT MOST OF PUERTO RICO WITHIN THE NEXT HOUR OR SO...BEFORE THIS SHOWER ACTIVITY DIMINISHES. LATEST SATELLITE IMAGES ARE SHOWING A RELATIVELY DRY SLOT PUSHING DOWNWARD ACROSS THE LOCAL ATLANTIC WATERS. THIS DRY AIR MASS IS EXPECTED TO ARRIVE TO THE NORTHERN COASTS OF THE LOCAL ISLANDS WITHIN THE NEXT FEW HOURS. THEREFORE...SHOWERS ARE EXPECTED TO DECREASE AS WELL AS CLOUD COVERAGE LATER THIS AFTERNOON INTO THE EVENING. HOWEVER...A FEW SHOWERS MAY DEVELOP OVER THE LOCAL ATLANTIC WATERS LATE THIS EVENING AND AFFECT PARTS OF THE NORTHERN COAST OF PUERTO RICO...BUT RAINFALL AMOUNTS ARE EXPECTED TO BE MINIMAL. WINDS WILL CONTINUE TO BLOW FROM THE NORTHEAST AT 5 TO 10 MPH WITH OCCASIONAL GUSTS ACROSS THE LOWER ELEVATIONS AND UP TO 20 MPH OVER MOUNTAIN AREAS. && .AVIATION...VFR CONDITIONS SHOULD PREVAIL ACROSS ALL TAF SITES FOR THE REST OF THIS AFTERNOON THROUGH MONDAY MORNING. A FEW SHOWERS AND EVEN A THUNDERSTORM OR TWO MAY BE POSSIBLE ACROSS TJBQ FROM 18Z TO 21Z...REDUCING THE VISIBILITY FOR THAT PERIOD. WINDS ARE EXPECTED TO CONTINUE TO BLOW FROM THE NORTHEAST AT 10 TO 20 MPH WITH HIGHER GUSTS ALONG THE NORTHERN COAST OF PUERTO RICO AT LEAST THROUGH THIS EVENING. && .PREV DISCUSSION... /ISSUED 527 AM AST SUN DEC 2 2007/ SYNOPSIS...A BROAD TROUGH EXTENDS FROM THE SOUTHEAST CARIBBEAN NORTHEASTWARD ACROSS THE LEEWARD ISLANDS AND INTO THE CENTRAL ATLANTIC WHERE IT HAS MERGED WITH A LOW PRESSURE CENTER. THIS LARGE FEATURE WILL COMBINE WITH STRENGTHENING HIGH PRESSURE ACROSS THE NORTHWEST ATLANTIC TO KEEP THE LOCAL AREA IN A PERSISTENT NORTHEAST WIND FLOW AND CONSIDERABLE EMBEDDED SHOWER ACTIVITY. THIS TROUGH WILL DRIFT VERY SLOWLY WEST NORTHWEST AND MOVE ACROSS THE REGIONAL CARIBBEAN WATERS BY TUESDAY...ACTING TO DIMINISH WINDS CONSIDERABLY TUESDAY AND WEDNESDAY. DISCUSSION...SCATTERED TO NUMEROUS SHOWERS CONTINUED TO AFFECT THE NORTHERN COAST OF PUERTO RICO. EARLIER TONIGHT THE SHOWERS WHERE CONCENTRATING FROM ARECIBO EAST TO LUQUILLO BUT IN THE LAST FEW HOURS THE WEATHER ACTIVITY HAVE SHIFTED WEST AFFECTING THE COAST FROM ARECIBO WEST TO AGUADA. THESE SHOWER WILL CONTINUE TO AFFECT THE ENTIRE NORTH COAST OF PR AS MORE SHOWERS WILL DEVELOP OVER THE ATLANTIC WATER AN MOVE ON SHORE THROUGH LATE THIS MORNING OR EARLY THIS AFTERNOON. THE GFS AND THE NAM MODELS ARE SUGGESTING A SIGNIFICANT DECREASE ON MOISTURE FOR TODAY. THE DRY BOUNDARY COULD ALREADY BE SEEN ON THE SATELLITE AND RADAR IMAGES...AFTER TIMING OUT THE ARRIVAL WILL BE REACHING OUR LOCAL AREA BETWEEN 12 PM AND 2 PM. BREEZY AND RAINY CONDITIONS OVER THE NORTHERN HALF OF PUERTO RICO ARE EXPECTED TO CONTINUE THROUGH AT LEAST WEDNESDAY. WINDS ARE EXPECTED TO BECOME MORE FROM THE EAST ON WEDNESDAY SHIFTING THE WEATHER ACTIVITY OVER EASTERN SECTIONS OF PUERTO RICO OVERNIGHT AND THE INTERIOR AND WESTERN SECTIONS DURING THE AFTERNOON. AVIATION... AXIS OF GREATEST MOISTURE ASSOCIATED WITH THE TROUGH OVER THE REGION IS SHIFTING WEST AND WILL CONTINUE TO FOCUS SHOWER ACTIVITY IN THAT DIRECTION AS THE DAY PROGRESSES. CONSIDERING THE QUICK MOVING NATURE OF THESE SHOWERS AS WELL AS THE RELATIVELY SHALLOW DEPTH OF LAYER MOISTURE...DONT EXPECT LOWER CEILING OR VISIBILITY CATEGORIES OTHER THAN PERHAPS A FEW MOMENTS AT TJBQ OVERNIGHT. ALSO...NOT SEEING MANY THUNDERSTORMS ALTHOUGH CANT RULE OUT THAT A FEW VERY ISOLATED TS MAY DEVELOP. OTHERWISE...EXPECT SHOWER ACTIVITY OVER MOST OF THE ISLAND DURING THE DAY...WITH MOST OF THE HEAVIER SHOWERS FOCUSED WEST OF ARECIBO. EXPECT WINDS TO TURN SLIGHTLY MORE NORTHEASTERLY OVER THE NEXT 24 HOURS...WITH THE SAME RELATIVE DAYTIME MINIMA AND NIGHTTIME MAXIMA THAT HAS BEEN EXPERIENCED LAST SEVERAL DAYS. MARINE...MODELS AND ACTUAL OBSERVATIONS ARE SHOWING A SLIGHT DECREASE ON WINDS WITH THE EXCEPTION OF THE MONA PASSAGE. THEREFORE THE SMALL CRAFT ADVISORY CONTINUES FOR THE ZONES 710 AND 740. MODELS ARE SUGGESTING ANOTHER WIND INCREASE FOR THIS AFTERNOON. THIS WIND SURGE IS EXPECTED TO LAST UNTIL MONDAY MORNING. AT THIS MOMENT MARINERS SHOULD EXERCISE CAUTION ACROSS THE ZONES 720...730 AND 750. EARLY THIS AFTERNOON WINDS ARE EXPECTED TO INCREASE TO ABOVE SCA CRITERIA ACROSS THE 720 AND 730 MARINE ZONES.
