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

BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1500 UTC.

..ITCZ...
ITCZ AXIS IS ALONG 4N77W 6N88W 4N100W 7N115W 6N140W. NO
SIGNIFICANT CONVECTION IS NOTED

DISCUSSION...
BROAD MID/UPPER LEVEL RIDGE N OF 15N W OF 120W. A SURFACE 1019
MB HIGH PRES CENTER IS ANALYZED NEAR 26N133W. THE MID/UPPER
LEVEL FLOW IS MOSTLY ZONAL FROM 10N TO 25N W OF 115W. SATELLITE
DERIVED WINDS INDICATE A 110-120 KT JET STREAM FROM 20N140W EWD
TO 20N115W WHERE THE FLOW SPLITS AND WEAKENS. WITH ONE BRANCH
MOVING NE INTO CENTRAL MEXICO NEAR 25N99W...AND THE OTHER BRANCH
SE TO 15N105W. CIRRUS CLOUDS ARE WITHIN 360 NM SE OF JET STREAM
OVER MEXICO. TRANSVERSE BANDING NOTED ON THE CIRRUS CLOUDS
INDICATING POSSIBLE UPPER LEVEL TURBULENCE. MODERATE TO STRONG
SUBSIDENCE FROM 25N TO 30N W OF 115W.

N OF THE JET A MID TO UPPER LEVEL TROUGH BETWEEN 110W AND 125W.
THE ASSOCIATED DEEP LAYERED CYCLONE IS CENTERED JUST N OF THE
AREA MOVING INLAND ALONG THE SOUTHERN CALIFORNIA COAST. ITS
SURFACE REFLECTION IS INDICATED AS A TROUGH FROM 32N116W 25N123W
26N130W.

STRONG SUBSIDENCE AND RESULTANT DRY AIR ALOFT COVERS THE AREA S
OF 15N E OF 110W. THIS SUBSIDENCE AND DRY AIR IS CONTINUING TO
SUPPRESS CONVECTION ALONG THE ITCZ.

MODERATE TO STRONG WINDS CONTINUE TO FLOW FROM THE CARIBBEAN
THROUGH THE GULF OF PAPAGAYO.
