AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
1144 AM AST MON JUN 11 2007

.UPDATE...PARTLY CLOUDY SKIES PREVAILED ACROSS THE LOCAL ISLANDS THIS MORNING.
THE NWS DOPPLER RADAR INDICATED SCATTERED SHOWERS OVER THE COASTAL
WATERS. CLOUDS AND ISOLATED SHOWERS DEVELOPED ACROSS PARTS OF THE
CENTRAL AND WEST INTERIOR SECTIONS OF THE ISLAND BY LATE MORNING.
THE WINDS WERE FROM THE SOUTHEAST AT NEAR 10 MPH.

THE RESIDUAL MOISTURE LEFT BEHIND THE WEAK TROPICAL WAVE...NOW OVER
THE CENTRAL CARIBBEAN...WILL COMBINE WITH DIURNAL HEATING...SEA
BREEZES DEVELOPMENT...AND LOCAL TERRAIN EFFECTS TO PRODUCE
CLOUDINESS...SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS...MAINLY
OVER THE WESTERN AND INTERIOR SECTIONS OF PUERTO RICO THIS
AFTERNOON. SOME OF THE RAINFALL WILL BE LOCALLY HEAVY AT TIMES. NO
SIGNIFICANT CHANGES WERE MADE TO THE INHERITED FORECAST WHICH HAS
HAD A GOOD HANDLE ON PRESENT AND EXPECTED CONDITIONS OVER THE NEXT
FEW DAYS.

&&

.PREV DISCUSSION... /ISSUED 409 AM AST MON JUN 11 2007/

SYNOPSIS...LOW PRESSURE FAR TO THE NORTH OF THE AREA AND HIGH
PRESSURE OVER THE CENTRAL ATLANTIC WILL MAINTAIN A SOUTHEAST TO
EAST SOUTHEAST WIND FLOW ACROSS THE REGIONAL WATERS FOR THE NEXT
SEVERAL DAYS. A WEAK TROPICAL WAVE LOCATED SOUTH OF WESTERN HISPANIOLA
EARLY THIS MORNING...WILL CONTINUE MOVING WEST AROUND 15
KNOTS...AWAY OF THE LOCAL AREA TODAY. LINGERING MOISTURE BEHIND THIS
WAVE WILL CONTINUE TO RESULT IN SHOWERS AND ISOLATED THUNDERSTORMS
ACROSS THE REGIONAL WATERS TODAY. ANOTHER TROPICAL WAVE ESTIMATED NEAR
47 WEST EARLY THIS MORNING WILL CONTINUE MOVING WEST NEAR 15 KNOTS
THROUGH AT LEAST THURSDAY WHEN EXPECTED TO BE NEAR THE LOCAL ISLANDS.

DISCUSSION...MOISTURE LEFT BEHIND BY A TROPICAL WAVE NOW MOVING
AWAY FROM THE AREA WILL COMBINE WITH THE LIGHT SOUTHEAST TO SOUTH
LOW LEVEL WIND FLOW TO PRODUCE SCATTERED TO NUMEROUS SHOWERS AND
ISOLATED THUNDERSTORMS IN A SIMILAR WAY THAN IN PREVIOUS SEVERAL
DAYS. AGAIN THE SLOW MOVEMENT OF THESE SHOWERS WILL RESULT IN
SIGNIFICANT ACCUMULATIONS OVER ISOLATED LOCALITIES IN PUERTO RICO.
THERE EXIST THE POSSIBILITY OF URBAN FLOODING. ENOUGH MOISTURE
WILL REMAIN OVER THE AREA TO HAVE SIMILAR EFFECTS IN THE WEATHER
PATTERN UNTIL TUESDAY. AN INCREASE IN THE WINDS WEDNESDAY MAY HELP
TO INHIBIT THE DIURNAL SEA BREEZE CONVERGENCE LEADING TO LESS
SHOWERS.

ADDITIONAL MOISTURE ASSOCIATED TO ANOTHER TROPICAL WAVE WILL
ARRIVE TO THE LOCAL AREA AROUND THURSDAY.

MARINE...OBSERVED MARINE CONDITIONS ALONG THE NORTHERN COAST OF
PUERTO RICO SHOWED QUIET SEAS. HOWEVER...SEAS CAN BECOME CHOPPY IN
THE VICINITY OF THE SHOWERS AND THUNDERSTORMS.

SJU WATCHES/WARNINGS/ADVISORIES...
