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 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1515 UTC.              

...SPECIAL FEATURES...

A COLD FRONT IS PUSHING SOUTHWARD IN THE EASTERN PACIFIC OCEAN
THAT IS OFF THE COAST OF BAJA CALIFORNIA. THE FRONT WILL
CONTINUE ITS MOVEMENT FOR THE NEXT 6 HOURS OR SO...DISSIPATING
DURING THE EARLY AFTERNOON HOURS OF TODAY. STRONG HIGH PRESSURE
THAT IS TO THE NORTHWEST OF THE FRONT HAS BEEN TIGHTENING THE
SURFACE PRESSURE GRADIENT IN THE EASTERN PACIFIC OCEAN. GALE-
FORCE WINDS ARE EXPECTED TO CONTINUE FOR THE NEXT 6 HOURS OR
SO...DIMINISHING DURING THE EARLY AFTERNOON HOURS OF TODAY.
THE STRONG NORTHWEST WINDS WILL BUILD MAXIMUM SEA HEIGHTS IN THE
AREA THAT IS OFF THE COAST OF BAJA CALIFORNIA IN THE RANGE OF
20 FEET TO 23 FEET. 

THE SAME BAJA CALIFORNIA-TO-EASTERN PACIFIC OCEAN COLD FRONT
CUTS ACROSS THE GULF OF CALIFORNIA FROM 30N109W TO 24N112W.
NORTHWEST-TO-NORTH GALE-FORCE WINDS ARE TO THE NORTH OF THE
FRONT TO 29N...ACCORDING TO THE LATEST SCATTEROMETER PASS. THE
SEA HEIGHTS ARE BUILDING TO 8 FEET. THE WINDS AND SEAS ARE
FORECAST TO SUBSIDE THIS AFTERNOON AS THE FRONT DISSIPATES AND
THE AREA OF HIGH PRESSURE WEAKENS.
  
...INTERTROPICAL CONVERGENCE ZONE...

A SURFACE TROUGH IS ALONG 07N85W 03N94W 03N105W. THE ITCZ
CONTINUES FROM 03N105W TO 03N110W 01N125W TO 03N140W. CONVECTIVE
PRECIPITATION...SCATTERED MODERATE TO ISOLATED STRONG FROM 04N
TO 08N BETWEEN 85W AND 90W...AND FROM 02N TO 04N BETWEEN 134W
AND 138W. 

...DISCUSSION...

A MIDDLE LEVEL TO UPPER LEVEL CYCLONIC CIRCULATION CENTER IS
NEAR 30N112W IN INTERIOR NORTHWESTERN MEXICO. A TROUGH EXTENDS
FROM THE 30N112W CYCLONIC CENTER TO 15N111W AND TO 09N114W. THIS
FEATURE SUPPORTS THE COLD FRONT THAT IS PART OF THE GALE-FORCE
WINDS THAT ARE IN THE GULF OF CALIFORNIA...AND IN THE EASTERN
PACIFIC OCEAN THAT IS OFF THE COAST OF BAJA CALIFORNIA.

AN UPPER LEVEL RIDGE IS ALONG 17N139W BEYOND 32N140W. UPPER
LEVEL ANTICYCLONIC WIND FLOW COVERS THE EASTERN PACIFIC OCEAN
TO THE WEST OF THE 30N112W 09N114W TROUGH.

A 1025 MB HIGH PRESSURE CENTER IS NEAR 29N133W. BROAD SURFACE
ANTICYCLONIC WIND FLOW COVERS THE EASTERN PACIFIC OCEAN FROM 07N
NORTHWARD FROM 110W WESTWARD...EXCEPT NEAR THE 30N109W 22N120W
COLD FRONT.

A SURFACE TROUGH IS ALONG 17N103W 15N104W 12N106W. CONVECTIVE
PRECIPITATION...ISOLATED MODERATE FROM 12N TO 17N BETWEEN 101W
AND THE TROUGH.
