TROPICAL WEATHER DISCUSSION FOR THE EASTERN PACIFIC OCEAN FROM 
THE EQUATOR TO 32N...EAST OF 140W.

BASED ON 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
2100 UTC.

...ITCZ...
THE INTERTROPICAL CONVERGENCE ZONE AXIS IS ANALYZED FROM 07N80W 
TO 03N95W TO 06N110W TO 04N125W TO 05N140W. NO SIGNIFICANT 
CONVECTION.

...DISCUSSION...

A COLD FRONT WILL MOVE INTO THE NORTHERN PART OF THE AREA LATE 
TONIGHT INTO SATURDAY MORNING. IT WILL BRING A ROUND OF FRESH TO 
STRONG NORTHWESTERLY WINDS TO THE AREA TO THE NORTH OF THE 
FRONT. NORTHWESTERLY SWELL ALSO WILL FOLLOW THE FRONT THROUGH 
LATE SATURDAY...WITH SEA HEIGHTS RANGING FROM 8 FEET TO 14 FEET 
AND PERIODS RANGING FROM 10 SECONDS TO 15 SECONDS. A DEEP LAYER 
TROUGH SUPPORTS THIS COLD FRONT. 

A BROAD AREA OF FRESH TO STRONG TRADE WINDS ARE BLOWING THROUGH 
THE REGION FROM THE EQUATOR TO 20N TO THE WEST OF 120W ACCORDING 
TO WINDSAT AND ASCAT DATA. THIS TRADE WIND FLOW WILL DIMINISH 
THROUGH TONIGHT AS THE HIGH PRES CURRENTLY LOCATED OVER THE NW 
WATERS WEAKENS AND SHIFTS SLIGHTLY TO THE WEST WHEN THE COLD 
FRONT PUSHES TO ITS EAST BY EARLY SATURDAY. SEA HEIGHTS ARE 
RANGING FROM 8 FEET TO 11 FEET IN THE AREA OF FRESH TO STRONG 
TRADES...LIKELY DUE TO NORTHEASTERLY SWELL. THIS WILL DECAY 
SLIGHTLY THROUGH SUNDAY AND BE CONTAINED TO AN AREA THAT IS TO 
THE SOUTH OF 10N TO THE WEST OF 120W.

GAP WIND FLOW THROUGH THE GULF OF PAPAGAYO IS PULSING TO 20 KT. 
THIS WEATHER PATTERN WILL PERSIST OVER THE NEXT COUPLE OF DAYS. 

GULF OF CALIFORNIA...WINDS ACROSS THE SOUTHERN PORTION OF THE 
GULF ARE DIMINISHING AS THE HIGH PRESSURE WEAKENS AND DRIFTS 
WESTWARD...AND THE LOW PRESSURE IN MEXICO FILLS. HOWEVER... 
WINDS WILL INCREASE OVER THE N PORTION OF THE GULF IN ABOUT 24 
HOURS AS THE ABOVE MENTIONED COLD FRONT ENTERS THE N WATERS.
