DURING THE NEXT FEW HOURS AS A LINE OF CONVECTION... ASSOCIATED WITH
THE FEEDER BANDS OF SANDY...CONTINUES TO MOVE WEST NORTHWEST TOWARDS
WESTERN PUERTO RICO. DUE TO ALREADY SATURATED SOILS...ANY ADDITIONAL
RAINFALL WILL LIKELY RESULT IN RAPID RISES IN STREAMS...CREEKS AND
RIVERS AS WELL AS INCREASE THE POTENTIAL FOR MUDSLIDES IN AREAS OF

.PREV DISCUSSION... /ISSUED 422 PM AST FRI OCT 26 2012/

SYNOPSIS...UPPER LEVEL RIDGE WILL REMAIN THE DOMINANT WX FEATURE
INTO EARLY NEXT WEEK. A SOUTH TO SOUTHWEST FLOW ASSOCIATED TO
SANDY WILL DOMINATE INTO MID NEXT WEEK. LARGE NORTHWEST SWELLS
WILL IMPACT THE ATLC COASTLINE AND MONA PASSAGE EARLY NEXT WEEK.

DISCUSSION...FEEDER BAND CONVERGENCE ASSOCIATED WITH SANDY HAS
WEAKENED CONSIDERABLY SINCE LAST NIGHT WHICH SHOULD LIMIT THE
EXTENT OF SHOWERS AND THUNDERSTORMS TONIGHT. SO AM NOT EXPECTING
A REPEAT OF LAST NIGHTS.

OVER THE NEXT SEVERAL DAYS...SOUTH TO SOUTHWEST FLOW AND BETTER
HEATING SHOULD STILL ALLOW FOR SCT SHOWERS AND THUNDERSTORMS
MAINLY ACROSS THE SOUTHWEST ON SAT AND THEN OVR NORTHEAST PR SUN
AND NEXT WEEK. IT WILL TURN NOTICEABLY HOTTER ESPECIALLY ON SUN AS
LOW TO MID LEVEL TEMPS WARM. MUCH DRIER AIR WILL WORK INTO THE
AREA FROM THE EAST MIDDLE OF NEXT WEEK.

AVIATION...BRIEF MVFR/IFR CONDS ARE STILL POSSIBLE ACROSS THE
TIST...TJPS AND TJSJ THROUGH LATE TONIGHT IN PASSING SHWRS. SHRA AND
ISOLD TSRA EMBEDDED IN A MOIST SOUTHEASTERLY FLOW WILL AFFECT THE
FLYING AREA THROUGH THE FORECAST PERIOD. MAINLY VFR CONDITIONS WILL
PREVAIL ELSEWHERE

MARINE...SCA WILL BE CANCELLED SHORTLY AS SOUTHWEST SWELLS HAVE
SUBSIDED AND LARGER NORTHWEST SWELL EVENT ASSOCIATED WITH SANDY HAVE
BEEN PUSHED BACK OR DELAYED TO MON.
