SPECIAL TROPICAL WEATHER OUTLOOK
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
755 AM PDT SUN JUN 21 2009

FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE..

SPECIAL OUTLOOK ISSUED TO UPDATE DISCUSSION OF LOW PRESSURE AREA
SOUTH OF ACAPULCO MEXICO.

1. UPDATED...SATELLITE IMAGES INDICATE THAT SHOWERS AND THUNDERSTORMS
ASSOCIATED WITH THE AREA OF LOW PRESSURE CENTERED ABOUT 150 MILES
SOUTHWEST OF ACAPULCO MEXICO CONTINUE TO BECOME BETTER ORGANIZED...
BUT THE LOW-LEVEL CENTER OF CIRCULATION IS NOT YET WELL-DEFINED. 
ONLY A SLIGHT INCREASE IN THE ORGANIZATION OF THIS SYSTEM WOULD
RESULT IN THE FORMATION OF A TROPICAL DEPRESSION...AND ADVISORIES
COULD BE INITIATED LATER TODAY.  THERE IS A HIGH CHANCE...GREATER
THAN 50 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING
THE NEXT 48 HOURS. HEAVY RAINS COULD AFFECT PORTIONS OF THE
SOUTHERN AND SOUTHWESTERN COAST OF MEXICO DURING THE NEXT DAY OR
TWO...AND INTERESTS IN THIS REGION SHOULD MONITOR THE PROGRESS OF
THIS SYSTEM.

2. AN AREA OF LOW PRESSURE LOCATED ABOUT 1600 MILES SOUTHWEST OF THE
SOUTHERN TIP OF BAJA CALIFORNIA IS PRODUCING A DISORGANIZED AREA OF
SHOWERS AND THUNDERSTORMS.  DEVELOPMENT OF THIS SYSTEM...IF ANY...
WILL BE SLOW TO OCCUR AS IT MOVES EAST-NORTHEASTWARD AT 5 TO 10 MPH
OVER THE NEXT COUPLE OF DAYS.  THERE IS A LOW CHANCE...LESS THAN 30
PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.
