.
SATELLITE ANALYSIS AND TRENDS...VERY LARGE EXTRA-TROPICAL SYSTEM IS SEEN
ON WV IMAGERY IN THE N ATLANTIC AND HAS REMAINED NEARLY STNRY OVER THE
PAST 24 HRS AT ABOUT 39N/55W. EXTREMELY LONG FRONTAL BDNRY WRAPPING INTO
THIS POWERFUL SYSTEM EXTENDS ACROSS MUCH OF THE N ATLANTIC TO THE TROPICAL
WATERS AROUND PR WHERE IT LIKELY TRANSITIONS INTO A DEFORMATION ZONE. LOOP
OF WV IMAGERY SHOWS THAT ONE S/WV LIFTED ACROSS PR ALREADY PRIOR TO 00Z
AND IS RESPONSIBLE FOR THE TRAILING LINE OF WARM TOP SHOWERS THAT REMAINS
OVER THE ISLAND. ANOTHER S/WV IS SEEN MOVING ALONG DUE N OF HISPANOLA
THAT SHOULD ALLOW FOR INCREASED INSTABILITY INTO TOMORROW. MICROWAVE
DATA SHOWS THE LOW LVL MOISTURE PLUME STILL CONTAINS NEAR 2" PW VALUES
S AND E OF PR..SOME OF WHICH MAY BE PULLED NWD BY THE APPROACHING S/WV.
.
CURRENT LINE OF MOSTLY SHOWER ACTIVITY WITH SOME HEAVIER POCKETS OF MORE
CONSTANT RAIN EXTENDS FROM THE MUNICIPALITIES OF SALINAS/GUAYAMA NEWD
TO CEIBA/FAJARDO ON THE ERN END OF THE ISLAND AND NEWD FROM THERE TO
STN TIST. THROUGH THE 0415Z IMAGE..WHICH WAS THE LAST PRIOR TO THE EVER
SHORTENING ECLIPSE PERIOD..TREND WAS FOR A SLIGHT COOLING TO MOST OF THE
CLOUD TOPS ALONG THE LINE OVER PR WITH THE MOST COOLING OCCURRING FROM
THE ERN TIP OF THE ISLAND TO TIST..THOUGH COLDEST CLOUD TOP TEMPS STILL
ONLY REACHED -20C. WITH SOME AREAS ON THE SE SIDE OF THE ISLAND HAVING
ALREADY RECEIVED SOME RAINFALL TODAY..ADDTL TRAINING SHOWERS IN THIS MOIST
ENVIRONMENT MAY EXACERBATE ANY ALREADY OCCURRING PROBLEMS. HOWEVER..LARGER
THREAT FOR TSTORMS AND POTENTIALLY HVY RAINFALL MAY NOT EXIST UNTIL
TOMORROW. SEE WEB ADDRESS IN ABOUT 10-15 MIN FOR GRAPHICAL ANALYSIS.
