LATEST DATA USED: G12  1445Z  CK
DMSP SSMI: 0940Z  NOAA AMSU: 1059Z
.
LOCATION...PUERTO RICO...
.
ATTN WFOS...SJU...
.
EVENT...INCRG CU STREETS MAY LEAD TO TSTM DEVELOPMENT OVER PUERTO RICO
.
SATELLITE ANALYSIS AND TRENDS...IMAGERY ANIMATION SHOWS THAT THE BULK
OF THE DEEP LAYERED MOISTURE ASSOCD WITH TS NOEL HAS MOVE TO THE W OF
THE ISLAND.  HOWEVER..VIS IMAGERY SUGGESTS THE POSSIBILITY OF ADDITIONAL
HVY SHOWERS/TSTMS DEVELOPING OVER PUERTO RICO THIS AFTN. LATEST VIS
IMAGE SHOWS CU HAS DEVELOPED OVER E AND SE SECTIONS..WITH ADDITIONAL CU
STREETS/LINES FORMING TO THE S AND SE OF THE ISLAND. THE MOST PRONOUNCED
CU/TCU APPEARING IN VIS IMAGERY EXTENDS FM ERN PUERTO RICO SEWD ACRS
VIEQUES AND ST CROIX..TO OVR 80 100 MI SE OF ST CROIX. MOVEMENT IS TWD
THE NW.
.
WITH THE INCR IN CU OVER SE/E PR AND TO THE SE..THE STEADY MOVEMENT OF
THE OFFSHORE CU TWD SE/E PR..ALONG WITH DECENT INSTABILITY OF -5 LI PER
GOES SOUNDER DATA..WOULD EXPECT A GOOD POSSIBILITY OF TSTM FORMATION
THIS AFTN. EARLIER CIRRUS OVERCAST OVER ERN PR HAS DIMINISHED AND
ALLOWED FOR INCRD SOLAR HEATING. PW'S ARE STILL QUITE HIGH..WITH NOAA
AMSU AND DMSP SSMI INDICATING VALUES RANGING UP TO 2.2-2.3". THUS..ANY
TSTM DEVELOPMENT WILL HAVE THE CAPABILITY OF PRODUCING VERY HVY RAINFALL
IN A SHORT PERIOD OF TIME..ESP WHERE CELL MERGERS OCCUR. AND WITH CU/TCU
MOVG TWD/CONVERGING OVER SE/E PR..SOME MERGERS CAN BE EXPECTED.
