1150 AM PDT FRI JUN 18 2010

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

THE NATIONAL HURRICANE CENTER IS ISSUING ADVISORIES ON TROPICAL
STORM BLAS LOCATED ABOUT 290 MILES SOUTHWEST OF MANZANILLO MEXICO.

THE AREA OF SHOWERS AND THUNDERSTORMS CENTERED A FEW HUNDRED MILES
SOUTH OF THE GULF OF TEHUANTEPEC HAS CONTINUED TO BECOME BETTER
ORGANIZED THIS MORNING...AND RECENT SCATTEROMETER DATA SUGGESTS A
SURFACE CIRCULATION HAS FORMED.  UPPER-LEVEL WINDS ARE MARGINALLY
CONDUCIVE FOR ADDITIONAL DEVELOPMENT...AND A TROPICAL DEPRESSION
COULD FORM DURING THE NEXT DAY OR SO AS THE SYSTEM MOVES SLOWLY
WESTWARD OR WEST-NORTHWESTWARD.  THERE IS A MODERATE CHANCE...40
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.
