TROPICAL WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
0405 UTC SAT JAN 29 2005

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 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0345 UTC.

..ITCZ...
INTERTROPICAL CONVERGENCE ZONE AXIS ALONG 4N70W 6N87W 4N131W
5N140W.  NO SIGNIFICANT CONVECTION.

..DISCUSSION...
W OF 110W
UPPER LEVEL RIDGE WITH AXIS FROM 26N112W TO EQUATOR AT 130W IS
ADVECTING THE ONLY SIGN OF MOISTURE IN WHOLE E PAC BASIN.  TWO
WIND MAXIMA CORES MERGE NEAR CREST WITH SIGNIFICANTLY LARGE AREA
OF SUBSIDENCE E OF 125W.  THAT MOISTURE IS OF LITTLE HELP FOR
ITCZ WHICH REMAINS WITH ONLY PATCHY ISOLATED MODERATE CONVECTION.

E OF 110W
E OF UPPER LEVEL RIDGE AXIS STRONG SUBSIDENCE SITS ACROSS ENTIRE
OF REMAINDER OF BASIN...WITH ONLY MINOR EXCEPTION A SMALL AREA
OF CLOUDS FROM 3N TO 6N E OF 89W.  DRYNESS EXTENDS WELL BEYOND
EPAC AREA INTO ENTIRE CARIBBEAN AND MOST OF S PAC BASINS.

WIND FLOW ACROSS CENTRAL AMERICA INTO EPAC CONTINUES THROUGH
GULFS OF PANAMA AND PAPAGAYO...AND LIKELY TO CONTINUE ANOTHER 48
HR WHILE GULF OF TEHUANTEPEC WIND SHOULD START BLOWING AS
SURFACE HIGH PRES RIDGE MOVES ACROSS GULF OF MEXICO NEXT 36 HR.
