TROPICAL WEATHER DISCUSSION FOR THE EASTERN PACIFIC OCEAN FROM 
THE EQUATOR TO 32N...EAST OF 140W. THE FOLLOWING INFORMATION IS 
BASED ON SATELLITE IMAGERY...WEATHER OBSERVATIONS...RADAR...AND 
METEOROLOGICAL ANALYSIS.

BASED ON 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
2045 UTC.

...SPECIAL FEATURES...

TROPICAL DEPRESSION TWO-E WAS UPGRADED TO TROPICAL STORM BORIS 
AT 03/1800 UTC. TROPICAL STORM BORIS IS CENTERED NEAR 14.9N 
94.1W AT 03/2100 UTC MOVING N AT 4 KT. ESTIMATED MINIMUM CENTRAL 
PRESSURE IS 999 MB. MAXIMUM SUSTAINED WIND SPEED IS 35 KT WITH 
GUSTS TO 45 KT. SCATTERED MODERATE/STRONG CONVECTION EXISTS N OF 
14N TO INLAND MEXICO BETWEEN 92W-95W. SCATTERED 
MODERATE/ISOLATED STRONG CONVECTION IS SEEN FROM 11N-15N BETWEEN 
89W-97W. THE MAIN THREAT ASSOCIATED WITH THIS SYSTEM IS VERY 
HEAVY RAINS...PARTICULARLY NEAR REGIONS OF HIGH TERRAIN. THIS 
COULD RESULT IN SIGNIFICANT AND DANGEROUS FLOODING AND MUD 
SLIDES. PLEASE SEE LATEST NHC FORECAST/ADVISORY UNDER AWIPS/WMO 
HEADERS MIATCMEP2/WTPZ22 KNHC FOR MORE DETAILS.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...           

MONSOON TROUGH AXIS EXTENDS FROM 9N78W TO 10N89W THEN RESUMES 
NEAR 13N112W TO 10N118W. ITCZ EXTENDS FROM 10N118W TO BEYOND 
6N140W. SCATTERED MODERATE/ISOLATED STRONG CONVECTION IS FROM 
3N-7N BETWEEN 81W-90W. 

...DISCUSSION...     

A 1033 MB HIGH IS CENTERED WELL N OF THE DISCUSSION AREA WITH A 
RIDGE AXIS EXTENDING S-SE INTO THE REGION THROUGH 32N132W TO 
22N127W. THE PRESSURE GRADIENT BETWEEN THIS SURFACE RIDGE AND 
THE LOWER PRESSURE OVER THE DESERT SW IS TIGHT ENOUGH TO SUPPORT 
FRESH TO LOCALLY STRONG WINDS OFF THE COAST OF BAJA CALIFORNIA 
WITH BUILDING SEAS. THESE CONDITIONS ARE EXPECTED TO PERSIST 
THROUGH THU MORNING. A TIGHTENING PRESSURE GRADIENT BETWEEN THIS 
SURFACE RIDGE AND LOWER PRESSURE ALONG THE ITCZ IS PRODUCING A 
SHORT-LIVED FRESH TO STRONG TRADE WINDS W OF 138W. WINDS AND 
SEAS WILL SUBSIDE OVER NIGHT. 

THE LEADING EDGE OF CROSS EQUATORIAL SWELLS WITH PERIODS AT 19-21 
SECONDS IS CURRENTLY REACHING THE COASTLINE OF SOUTHERN MEXICO 
AND CENTRAL AMERICA...INCLUDING ALSO THE GULF OF PANAMA AND THE 
GULF OF TEHUANTEPEC. SEAS OF 8-9 FT ASSOCIATED WITH THESE SWELLS 
ARE CURRENTLY REACHING TO 6N BETWEEN 81W AND 100W...WITH THE 
EXCEPTION IN THE LEE SIDE OF THE GALAPAGOS. THESE SEAS WILL 
GRADUALLY SUBSIDE THROUGH WED EVENING.
