SATELLITE ANALYSIS AND TRENDS...LATEST GOES IMAGERY SHOWS CONVECTION TO
THE NW AND S OF PUERTO RICO. ATTM..THE CONVECTION S OF THE ISLAND HAS
BEEN DRIFTING NWD..WHILE THE CONVECTION TO THE NW HAS SHOWN LTL MOVEMENT. 
GOES IMAGERY REVEALS SEVERAL FEATURES PLAYING A ROLE IN THE CONVECTIVE
DEVELOPMENTS. FIRST..TO THE N...GOES WV IMAGERY ANIMATION SHOWS NW-SE
UPPR LVL JET ASSOCD WITH TROPICAL WAVE E OF YUCATAN/MX. THE DEVELOPMENT
OF THE TSTMS NW OF PUERTO RICO COINCIDED WITH THE LEADING EDGE OF THE JET
STREAK REACHING THE AREA. THE TSTMS TO THE S OF THE ISLAND ARE MORE
ASSOCIATED WITH LOW TO MID LEVEL VORT CENTERED NR 17N 67W AND OVERALL
PERSISTENT MOIST LOW LEVEL SERLY FLOW. MICROWAVE PW IMAGERY ANIMATION
SHOWS EXTENSIVE TROPICAL PW PLUME..WITH VALUES OF 2"PLUS OVER THE REGION. 
THIS PLUME EXTENDS ALL THE WAY TO THE WEST COAST OF AFRICA.  NEARBY GOES
SOUNDER DATA ALSO INDICATES 2"PLUS PWS AS WELL AS INSTABILITY THROUGHOUT
THE REGION.
.
FOR TODAY..EVEN THOUGH NWRLY FLOW AT UPPR LEVELS HAS BEEN SHEARING OFF
THE CONVECTIVE CLOUDS TOPS..LOW LEVEL FLOW CONTINUE TO PUMP CU/TCU NWWD
ACRS THE ISLAND. WITH CURRENT INSTABILITY..AND FURTHER DAYTIME HEATING
..WOULD EXPECT TSTMS TO DEVELOP OVER THE ISLAND AS WELL. WITH HIGH PWS
AND DECENT INSTABILITY SOME HVY DOWNPOURS ARE LIKELY.  LATER
ON..TONIGHT..MICROWAVE DATA INDICATES SOME DRIER AIR WILL PUSH IN FROM
THE WEST. MICROWAVE LOOP SHOWS THAT N OF 10 AND W OF 60W PW VALUES
RAPIDLY DECR TO BELOW 1.5".
