EVENT...CONVECTION BUILDING NORTHWARD AND EASTWARD ACROSS THE ISLAND
WITH ACTIVITY OVER CENTRAL PORTION OF THE ISLAND NOT MOVING MUCH RECENTLY.
.
SATELLITE ANALYSIS AND TRENDS...TRENDS FROM EARLIER SPENES MESSAGE
CONTINUE TO SHOW THE ABSOLUTE MAX (2" PWS) OF THE HIGHEST LOWER LEVEL
MOISTURE SHIFTING WEST OF PUERTO RICO. HOWEVER THE ISLAND IS STILL IN
THE CENTER OF THE TRAILING MOISTURE PLUME WITH 1.7"-1.8" PW VALUES
PRESENT. RECENT IR/VIS IMAGES SHOW ACTIVITY WHICH FORMED OVER THE
WESTERN PORTION OF THE ISLAND HAS EXHIBITED OUTFLOW CHARACTERISTICS AS
IT SPREAD NORTHWARD AND EASTWARD. WHILE THE NORTHERN PORTION OF THE
ACTIVITY HAS BOWED OFF THE COAST, THE EASTERN PART HAS SLOWED DOWN A
BIT WHILE FOCUSING A MORE PROLONGED PERIOD OF HEAVY RAINFALL ACROSS
THE NORTH CENTRAL MUNICIPALITIES...(APPROXIMATE AREA FROM BARCELONETA
TO CIALES/MOROVIS). CLOUD TOPS HAVE COOLED DURING THE PAST 1-2 HOURS
ON IR LOOP WHILE VISIBLE LOOP SHOWS GOOD EASTERLY INFLOW INTO THE LINE
AS SEEN IN CU FIELD MOVEMENT. BASED ON THE ENHANCEMENT AND PERSISTENCE
OF THE ACTIVITY AND THE AMOUNT OF MOISTURE PRESENT, BELIEVE RAINS OF
AT LEAST 2-3" IF NOT LOCALLY HIGHER THAN 3" HAS FALLEN IN THE PAST 1-2
HOURS OVER APPROXIMATE AFORMENTIONED MUNICIPALITIES OF NORTH CENTRAL
PUERTO RICO. A QUICK LOOK AT THE 1945Z IMAGE DOES SHOW SOME CLOUD TOP
WARMING WITH THE EASTERN PART OF THE LINE BUT VISIBLE IMAGERY DOES STILL
INDICATE THE PRESENCE OF ACTIVE OVERSHOOTING TOPS WITH ESTIMATED RATES
OF AT LEAST 1.5"-2.0"/HR CONTINUING. A VERY SLIGHT EASTWARD DRIFT TO
THE MOST INTENSE CONVECTION HAS ALSO BEEN NOTED.
