500 PM PDT MON SEP 14 2009

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

1. A BROAD AREA OF LOW PRESSURE LOCATED ABOUT 300 MILES SOUTHWEST OF
MANZANILLO MEXICO CONTINUES TO PRODUCE A LARGE AREA OF SHOWERS AND
THUNDERSTORMS. ALTHOUGH THERE ARE NO SIGNS OF A WELL-DEFINED
SURFACE CIRCULATION AT THIS TIME...ENVIRONMENTAL CONDITIONS ARE
FAVORABLE FOR DEVELOPMENT...AND A TROPICAL DEPRESSION COULD FORM AS
THIS SYSTEM MOVES SLOWLY WEST-NORTHWESTWARD DURING THE NEXT DAY OR
TWO. 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.
