NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
500 PM PDT FRI AUG 28 2009

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

1. SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A LOW PRESSURE AREA
LOCATED ABOUT 210 MILES SOUTH-SOUTHWEST OF ACAPULCO MEXICO HAVE
BECOME SIGNIFICANTLY BETTER ORGANIZED DURING THE PAST SEVERAL HOURS
AND A TROPICAL DEPRESSION APPEARS TO BE FORMING. IF THIS TREND
CONTINUES...ADVISORIES WOULD BE INITIATED TONIGHT OR TOMORROW
MORNING. THE LOW IS MOVING WEST-NORTHWESTWARD NEAR 10 MPH AND THERE
IS A HIGH CHANCE...GREATER THAN 50 PERCENT...OF THIS SYSTEM
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

2. SHOWER AND THUNDERSTORMS ASSOCIATED WITH A BROAD AREA OF LOW
PRESSURE LOCATED ABOUT 1030 MILES SOUTHWEST OF THE SOUTHERN TIP OF
BAJA CALIFORNIA HAVE CHANGED LITTLE THIS AFTERNOON. UPPER-LEVEL
WINDS APPEAR FAVORABLE FOR ADDITIONAL DEVELOPMENT OF THIS SYSTEM
DURING THE NEXT COUPLE OF DAYS AS IT MOVES WEST-NORTHWESTWARD AT 10
TO 15 MPH. THERE IS A HIGH CHANCE...GREATER THAN 50 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.
