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

BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0900 UTC.

...ITCZ...
ITCZ AXIS ALONG 3N78W 5N89W 3N102W 7N120W 6N140W. SCATTERED 
MODERATE CONVECTION WITHIN 120 NM OF AXIS FROM 92W TO 101W. 
SCATTERED MODERATE ISOLATED STRONG CONVECTION WITHIN 240 NM N OF 
AXIS FROM 112W TO 117W...AND WITHIN 120 NM N OF AXIS FROM 122W 
TO 125W.

...DISCUSSION...
E OF 115W....A QUIKSCAT PASS FROM THIS PAST EVENING SHOWED GALE 
FORCE WINDS THROUGH THE GULF OF TEHUANTEPEC. A JASON ALTIMETER 
PASS FROM AROUND THE SAME TIME SHOWED SEAS TO 12 FT RELATED TO 
THE TEHUANTEPEC WINDS. THE GALE FORCE WINDS WILL PERSIST MOST OF 
TODAY...THEN DIMINISH SLIGHTLY OVERNIGHT AS HIGH PRES OVER THE 
NRN GULF OF MEXICO SHIFTS E. MEANWHILE SW SWELL OF 6 TO 8 FT 
WITH PERIODS TO 15S IS PROPAGATING TOWARD THE CENTRAL AMERICAN 
COAST. WINDS OVER THE GULF OF PAPAGAYO ARE EXPECTED TO INCREASE 
AS ELY TRADES OVER THE CARIBBEAN PICK UP IN THE NEXT COUPLE OF 
DAYS. LIKEWISE THE GULF OF PANAMA WILL INCREASE SLIGHTLY THROUGH 
MID WEEK. ALOFT...UPPER RIDGE EXTENDS FROM OFF THE BAJA COAST TO 
AN UPPER ANTICYCLONE IS CENTERED NEAR 7N95W. UPPER DIVERGENCE ON 
THE SW SIDE OF THE ANTICYCLONE IS ENHANCING MODEST CONVECTION 
ALONG THE ITCZ BETWEEN 92W AND 101W. DIVERGENCE BETWEEN THE 
UPPER RIDGE AXIS AND AN UPPER CYCLONE NEAR 3N115W IS ENHANCING 
SCATTERED MODERATE TO STRONG CONVECTION ALONG AND N OF ITCZ 
BETWEEN 112W AND 117W. 

W OF 115W...UPPER SHORT WAVE N OF 20N ALONG 140W IS DIGGING NE. 
THIS IS WEAKENING A 1026 MB SURFACE HIGH PRES CELL NEAR 32N135W. 
THE SURFACE HIGH WILL STRENGTHEN THROUGH TODAY AS THE UPPER 
SHORT WAVE LIFTS OUT. THIS WILL ALLOW GRADUALLY STRENGTHENING 
TRADES S OF THE SURFACE HIGH...AND INTRODUCE FRESH NLY FLOW NEAR 
THE NRN BAJA COAST THROUGH THU.
