NWS San Juan, PR wrote its last area forecast discussion before the first event at Sep 15, 6:35 AM AST, 8 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN JUAN PR 635 AM AST THU SEP 15 2005 .DISCUSSION... BROAD UPPER TROF COVERING MUCH OF THE CENTRAL AND W CENTRAL ATLC EXTENDS SW INTO THE SW N ATLC THIS MORNING...WITH TUTT LOW BEGINNING TO PINCH OFF AND DIG TOWARDS P.R. AND HISPANIOLA THIS MORNING. THIS WILL CREATE VERY UNSTABLE CONDITIONS ALOFT TODAY...AND TO A LESSER DEGREE THROUGH THE UPCOMING WEEKEND. LOW TO MID LEVEL VORT WITH ASSOCIATED WEAK SURFACE REFLECTION EXTENDS FROM THE OPEN ATLC TO OUR NNE...S INTO THE SPANISH AND US VIRGIN ISLANDS...AND THEN SW INTO THE E CENTRAL ATLC...MOVING SLOWLY W. THIS FEATURE WILL SHIFT SLOWLY WNW THROUGH TONIGHT...BRINGING AMPLE LOW TO MID LEVEL MOISTURE FOR VERY ACTIVE DIURNAL CONVECTION. STRONG TSTORMS YIELDING HEAVY PRECIP AND POSSIBLE SMALL HAIL WILL BE POSSIBLE TODAY ACROSS THE INTERIOR...W AND NW OF P.R. BUT WITH LESSER CHANCES ELSEWHERE. ALL THIS WEATHER SHOULD GRADUALLY CLEAR TO THE WNW LATER TONIGHT. NEXT LOW TO MID LEVEL WEATHER FEATURE TO AFFECT THE AREA WILL BE COLD CORE TROPICAL WAVE...WHICH ORIGINATED AS A TUTT REFLECTION...ALONG 56 WEST AT OUR LATITUDE THIS MORNING. GFS IS FORECASTING THIS FEATURE TO MOVE ACROSS THE LOCAL AREA FRIDAY EVENING THROUGH SATURDAY...WITH SUBSIDENCE AHEAD OF IT MUCH OF FRIDAY. LLVL STEERING FLOW CONTINUES TO BE FORECAST SE TO NW ACROSS THE REGION AT THAT TIME...TAKING MUCH OF THE MODEST MOISTURE WITH THIS TROF JUST TO THE NORTH OF THE LOCAL ISLANDS. I AM SUSPICIOUS THAT GFS IS CONTINUING WITH A SELY BIAS IN THE LLVL FLOW ACROSS THE REGION...MORE APPARENT AT THE SURFACE THAN IN THE LLVLS...AND HAVE BEEN CAUTIOUS WITH THIS IN MY MARINE FORECASTS. THE NEXT FEATURE OF INTEREST FOR THE LOCAL REGION IS A LARGE CONVECTIVE COMPLEX ACROSS THE CENTRAL TROPICAL ATLC LOCATED WITHIN THE ITCZ. EXAMINATION OF THE PAST 7-10 DAYS OF DATA SUGGESTS TO ME THAT THERE ARE TWO VORT CENTERS WITHIN THIS AREA OF DISTURBED WEATHER...ONE A PIECE OF AN AEW AT 47.5W THAT WAS SEVERELY STRETCHED THEN SPLIT AS IT EXITED AFRICA...AND REMAINS LINKED TO THE TROF AT 56 WEST...AND THEN NEXT A LOW LAT TROPICAL WAVE ALONG 45-46. CIMSS LLVL VORT FIELDS AND RECENT QUIKSCAT PASSES SUGGEST AN ELONGATED CYCLONIC CIRCULATION. WEAK ANTICYCLONIC SHEAR ALOFT AND DEEP MOISTURE WITH THIS FEATURE OFFER THE POTENTIAL FOR FURTHER GRADUAL ORGANIZATION INTO A TROPICAL CYCLONE OVER THE NEXT FEW DAYS. THE TWO LLVL VORTS WILL LIKELY HAVE TO MERGE OR CONGEAL BEFORE THIS OCCURS. NHC COMPUTER MODELS HAVE BEEN SHIFTING BACK AND FORTH BETWEEN AN EVENTUAL NW AND WNW MOTION THROUGH 120 HOURS...WITH PAST TWO GFDL RUNS LIFTING STRONGLY N OR NNW. HOWEVER...THIS SYSTEM HAS YET TO DEVIATE FROM A WLY MOTION. A LARGE MID TO UPPER LEVEL CYCLONIC CIRCULATION TO THE SW AND ACROSS THE SOUTHERN HEMISPHERE...AND INCREASING MID LEVEL WEAKNESS N THRU NE OF THE LESSER ANTILLES SHOULD PROVIDE THE ENVIRONMENT TO MAKE THAT NW AND THEN NLY TURN IN A FEW DAYS. HOWEVER...THE FARTHER WEST THIS SYSTEM MOVES...THE LATER THE TURN. THAT BEING SAID...ALL INTERESTS IN THE E AND NE CARIBBEAN SHOULD MONITOR THIS SYSTEM CLOSELY. && .PRELIMINARY POINT TEMPS/POPS...
