1005 UTC MON JUN 16 2014

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 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0900 UTC.

...TROPICAL WAVES...                                            
A TROPICAL WAVE IS MOVING WEST WITH AXIS OF THE WAVE NEAR 95W. 
THE INTERACTION OF THE WAVE WITH THE MONSOON TROUGH HAS RESULTED 
IN THE DEVELOPMENT OF A 1009 MB LOW PRESSURE CENTER EMBEDDED 
WITHIN THE MONSOON TROUGH NEAR 09N95W. ACTIVE CONVECTION 
ASSOCIATED TO THE LOW AND TROPICAL WAVE IS NOTED WITHIN 210 NM 
SOUTH OF THE MONSOON TROUGH BETWEEN 93W AND 97W. THE LOW AND 
TROPICAL WAVE ARE EXPECTED TO DRIFT WESTWARD OVER THE NEXT 48 
HOURS.
 
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...              
THE MONSOON TROUGH EXTENDS FROM 09N84W TO LOW PRES NEAR 09N95W 
TO 06N109W WHERE LOW LEVEL WINDS SUGGEST A TRANSITION TO ITCZ 
WHICH EXTENDS TO BEYOND 07N140W. SCATTERED MODERATE ISOLATED 
STRONG CONVECTION WAS NOTED WITHIN 210 NM S OF TROUGH BETWEEN 
85W AND 88W. SCATTERED MODERATE ISOLATED STRONG CONVECTION WAS 
NOTED WITHIN 210 NM S OF TROUGH BETWEEN 90W AND 100W. SCATTERED 
MODERATE ISOLATED STRONG CONVECTION WAS NOTED WITHIN 60 NM OF 
ITCZ W OF 133W.

...DISCUSSION...                                                 
POST-TROPICAL REMNANT LOW CRISTINA IS CENTERED NEAR 21N115W. 
LATEST OBSERVATIONS SUGGEST THAT 20-25 KT WINDS AND SEAS TO 8 FT 
CONTINUE WITHIN 45 NM OF THE CENTER OF THE REMNANT LOW. WINDS 
AND SEAS WILL CONTINUE TO DECREASE AND SHOULD FALL BELOW 
ADVISORY CRITERIA BY TONIGHT. 

HIGH PRESSURE OF 1032 MB CENTERED WELL NW OF AREA NEAR 38N148W 
EXTENDS A RIDGE SE TO NEAR 30N120W. THE PRESSURE GRADIENT 
BETWEEN THE RIDGE AND LOWER PRESSURE IN THE VICINITY OF THE ITCZ 
IS MAINTAINING MAINLY GENTLE TO MODERATE WINDS OVER THE WESTERN 
FORECAST WATERS. SIMILAR CONDITIONS ARE EXPECTED TO CONTINUE 
DURING THE NEXT COUPLE DAYS.
