TROPICAL WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
0405 UTC MON 10 FEB 2003

EASTERN PACIFIC OCEAN FROM 32N TO THE EQUATOR...EAST OF 140W.

SPECIAL FEATURES...
NONE.

BASED ON 10/0000 UTC SURFACE SYNOPTIC ANALYSIS...
..1002 MB LOW IS CENTERED NEAR 27N130W WITH A COLD FRONT
EXTENDING SW TO 22N130W THEN 16N139W AND A WARM FRONT
STRETCHING EWD TO NEAR 24N120W. AN OCCLUDED FRONT WRAPS NWWD
TO A 1007 MB LOW NEAR 29N135W. THIS LOW WILL CONTINUE TO MOVE
SSE AND MERGE WITH THE STRONGER LOW TO THE SE WITHIN 24
HOURS. VIRTUALLY ALL OF THE STRONGEST CONVECTION HAS SHIFTED
TO THE N OF THE OCCLUDED FRONT WITH SCATTERED MODERATE
CONVECTION FROM 27N-31N BETWEEN 128W-133W. ISOLATED SHOWERS
ARE ALSO OCCURRING WITHIN 60NM OF THE COLD FRONT AND WITHIN
AN AREA S OF THE OCCLUDED FRONT FROM 24N-27N BETWEEN
132W-135W.
..TROUGH EXTENDS FROM 6N132W-20N125W AND IS BEING PULLED NWD BY
THE FLOW WITHIN THE WARM SECTOR OF THE COMPLEX LOW TO THE N.
THE LATEST SATELLITE IMAGERY ALSO INDICATES THAT A WEAK LOW
MAY BE TRYING TO FORM ALONG THE SW EDGE OF AN EXPANDING
BAROCLINIC LEAF CLOUD NEAR 22N124W. SCATTERED MODERATE
CONVECTION FROM 19N-22N BETWEEN 120W-123W WITH ISOLATED
MODERATE CELLS TO THE S FROM 16N-18N BETWEEN 119W-121W.
..RIDGE EXTENDS SWD ALONG BAJA CALIFORNIA TO 13N BETWEEN
108W-118W.

INTERPRETATION OF SATELLITE IMAGERY THROUGH 10/0315 UTC...

ITCZ...
AXIS OF ITCZ RELATED CLOUDS/CONVECTION IS CENTERED ALONG 2N78W
4N86W 5N96W 3N103W 8N128W 6N140W. ISOLATED MODERATE CONVECTION
WITHIN 60NM OF THE AXIS BETWEEN 84W-88W. ISOLATED SHOWERS WITHIN
30NM OF THE AXIS BETWEEN 93W-96W AND BETWEEN 109W-119W. WIDELY
SCATTERED WEAK TO MODERATE WITHIN 60NM OF THE AXIS BETWEEN
126W-129W.

ELSEWHERE SOUTH OF 32N...
ISOLATED CELLS OF MODERATE CONVECTION ALONG AND JUST INLAND OF
THE ECUADOR/COLOMBIA COASTLINE BETWEEN EQ-6N.
