NWS NATIONAL HURRICANE CENTER MIAMI FL
1605 UTC MON MAY 06 2013

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 
1500 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...       
MONSOON TROUGH EXTENDS FROM 08N78W TO 09N108W. ITCZ AXIS EXTENDS 
FROM TO 10N112W TO 06N140W.  SCATTERED MODERATE ISOLATED STRONG 
ARE LOCATED WITHIN 60 NM N AND 120 NM S OF AXIS FROM 100W TO 
125W.

...DISCUSSION...                                                 
AT THE SURFACE...A WEAK 1020 MB HIGH PRESSURE IS CENTERED NEAR 
25N138W WITH A RIDGE EXTENDING TO ITS EAST.  WEAK TROUGHS ARE 
ANALYZED OVER THE GULF OF CALIFORNIA...CENTRAL MEXICO...AND 
ALONG 110W NEAR 10N...THOUGH NONE OF THESE ARE ASSOCIATED WITH 
ANY SIGNIFICANT WEATHER.  IN THE UPPER LEVELS...A SHORT-WAVE 
TROUGH IS QUICKLY PUSHING EASTWARD ACROSS NW MEXICO.  UPPER- 
LEVEL RIDGING IS LOCATED ALONG 09N ACROSS MOST OF THE TROPICAL 
NORTHEAST PACIFIC...WITH MODERATE ZONAL WESTERLIES PREVAILING 
NORTH OF THERE.  WHILE SOME UPPER-LEVEL MOISTURE AND CIRRUS ARE 
BEING ADVECTED NORTHEASTWARD TOWARD CENTRAL MEXICO FROM THE ITCZ 
CONVECTION...THIS LIKELY IS CONTRIBUTING TOWARD LITTLE OR NO 
PRECIPITATION.

CURRENTLY...AND ALL THE WAY THROUGH SATURDAY...THERE ARE NO 
WINDS OF EVEN STRONG BREEZE NOR ANY SIGNIFICANT WAVEHEIGHTS OF 
EVEN 8 FT ANTICIPATED IN OUR ENTIRE AREA OF RESPONSIBILITY.  THE
