TROPICAL WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
1005 UTC FRI FEB 04 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 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0900 UTC.

..ITCZ...
ITCZ AXIS ALONG 4N78W 8N88W 6N105W 13N113W 7N131W 7N140W. WIDELY
SCATTERED MODERATE CONVECTION WITHIN 90 NM N OF THE AXIS FROM
109W TO 115W.

DISCUSSION...

W OF 105W...
DOMINATING MIDDLE TO UPPER LEVEL LOW IS CENTERED NEAR 28N119W
WITH ENVELOPE OF CYCLONIC CIRCULATION FOUND N OF 19N BETWEEN
131W AND 111W. AREA OF STRONG SUBSIDENCE IS FOUND W OF THE LOW
CENTER IN AREA OF MODERATE W CONVERGING WITH NW WINDS ALOFT.
VERY ACTIVE SOUTHERN BRANCH OF THE JET EXTENDS ALONG THE
SOUTHERN PERIPHERY OF THIS LOW WITHIN 120 NM OF LINE 22N139W
17N123W THEN TURNING NE TOWARD THE INLAND PORTIONS OF N MEXICO
NEAR 24N109W. CIMSS SATELLITE DERIVED DATA INDICATES WINDS OF
100 TO 120 KT FOUND WITHIN THIS JET. SURGING NE BRANCH OF JET
INTO MEXICO IS HELPING TO ADVECT SUBSTANTIAL MIDDLE TO UPPER
LEVEL MOISTURE INTO THAT AREA OF MEXICO TONIGHT.

AT THE SURFACE...DIVERGENT FLOW ALOFT SE OF THE MIDDLE TO UPPER
LOW IS HELPING TO SPARK SOME WIDELY SCATTERED CONVECTION WITHIN
THE ITCZ NEAR 112W.

E OF 105W...
UPPER RIDGE DOMINATES AREA AND CONTINUES TO STIFLE ANY
CONVECTIVE ACTIVITY IN THIS AREA OF THE E PACIFIC.

AT THE SURFACE...STRONG WINDS...20 TO 25 KT....CONTINUE TO
FUNNEL INTO THE GULFS OF PAPAGAYO AND PANAMA AND WILL PERSIST
FOR THE NEXT TWO DAYS. SIMILARLY...A MINIMAL GALE EVENT IN THE
GULF OF TEHUANTEPEC IS EXPECTED TO WEAKEN BELOW GALE FORCE IN 36
HOURS...AND CONTINUE TO BLOW AT NEAR 25 KT THROUGH 48 HOURS.
