FOR THE EASTERN AND CENTRAL NORTH PACIFIC EAST OF 180 LONGITUDE:
CENTRAL PACIFIC (CP90):
A TROUGH OF LOW PRESSURE LOCATED SEVERAL HUNDRED MILES SOUTHEAST OF
THE HAWAIIAN ISLANDS IS PRODUCING A BROAD AREA OF SHOWERS AND
THUNDERSTORMS. RECENT SATELLITE-DERIVED WIND DATA INDICATE THAT THE
SYSTEM REMAINS AN OPEN TROUGH. ENVIRONMENTAL CONDITIONS APPEAR
CONDUCIVE FOR GRADUAL DEVELOPMENT OF THIS SYSTEM THROUGH EARLY NEXT
WEEK, AND A TROPICAL DEPRESSION COULD FORM AS THE SYSTEM MOVES
WESTWARD TO WEST-NORTHWESTWARD ACROSS THE CENTRAL PACIFIC, REMAINING
WELL SOUTH OF THE HAWAIIAN ISLANDS.
* FORMATION CHANCE THROUGH 48 HOURS...MEDIUM...40 PERCENT.
* FORMATION CHANCE THROUGH 7 DAYS...MEDIUM...60 PERCENT.
WELL SOUTHEAST OF THE HAWAIIAN ISLANDS:
ANOTHER AREA OF SHOWERS AND THUNDERSTORMS IS ASSOCIATED WITH A
TROUGH OF LOW PRESSURE LOCATED ABOUT 1000 MILES EAST-SOUTHEAST
OF THE HAWAIIAN ISLANDS. ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE
FOR SLOW DEVELOPMENT OF THIS SYSTEM THIS WEEKEND INTO EARLY NEXT
WEEK AS IT MOVES WESTWARD OR WEST-SOUTHWESTWARD INTO THE CENTRAL
PACIFIC, REMAINING WELL SOUTH OF THE HAWAIIAN ISLANDS.
* FORMATION CHANCE THROUGH 48 HOURS...LOW...NEAR 0 PERCENT.
* FORMATION CHANCE THROUGH 7 DAYS...LOW...30 PERCENT.
OFFSHORE OF SOUTHWESTERN MEXICO:
AN AREA OF LOW PRESSURE IS EXPECTED TO FORM LATE THIS WEEKEND OR
EARLY NEXT WEEK SEVERAL HUNDRED MILES SOUTH-SOUTHWEST OF THE COAST
OF SOUTHWESTERN MEXICO. ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE
FOR GRADUAL DEVELOPMENT THEREAFTER, AND A TROPICAL DEPRESSION IS
LIKELY TO FORM NEXT WEEK WHILE THE SYSTEM MOVES GENERALLY
WEST-NORTHWESTWARD.
* FORMATION CHANCE THROUGH 48 HOURS...LOW...NEAR 0 PERCENT.
* FORMATION CHANCE THROUGH 7 DAYS...HIGH...70 PERCENT.
