TROPICAL WEATHER DISCUSSION FOR THE EASTERN PACIFIC OCEAN FROM 
THE EQUATOR TO 32N...EAST OF 140W. 

BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0845 UTC.
 
...ITCZ...
ITCZ AXIS IS ALONG 5N77W 5N107W 8N140W. NO SIGNIFICANT 
CONVECTION NOTED.

...DISCUSSION...

POLAR JET DIVING SWD ALONG 110W TONIGHT WILL SHARPEN AN UPPER 
TROUGH OVER MEXICO BUT HAVE LITTLE AFFECT ON OUR MARINE REGION. 
BROAD MID LEVEL RIDGE ALONG 135W COVERS MOST OF THE REGION W OF 
120W. ON THE SURFACE TONIGHT A 1034 MB HIGH ANCHORS THE PACIFIC 
RIDGE NEAR 33N137W WITH IT'S AXIS EXTENDING SE TO 15N105W. THE 
RIDGE IS RESPONSIBLE FOR NE TRADES 20 TO 25 KT W OF 120W WITH 
SEAS TO 12 FT. WINDS ALONG THE BAJA COAST ARE NLY TO 20 KT WITH 
SEAS 6 TO 8 FT. GAP WINDS ARE MOSTLY LIGHT. 

LATER DAY 1 THE BROAD MID LEVEL RIDGE WILL SLOWLY MOVE TO E TO 
ALONG 130W BLOCKING THE WESTERLIES TO THE N AND NE. ON THE 
SURFACE LATER DAY 1 LITTLE CHANGE TO THE PACIFIC RIDGE AND NE 
TRADES. WINDS ALONG THE BAJA COAST WEAKEN TO 10 TO 15 KT. GAP 
WINDS REMAIN LIGHT.

FOR DAY 2 THE MID LEVEL RIDGE IS FORECAST TO WEAKEN BUT REMAIN 
ALONG 130W. SWLY MID LEVEL FLOW BEGINS TO WORK IT'S WAY TOWARD 
140W WHICH WILL HELP ERODE THE W SIDE OF THE RIDGE. ON THE 
SURFACE DAY 2 THE PACIFIC RIDGE WILL WEAKEN ABOUT 4 MB AND NE 
TRADES DECREASE SLIGHTLY. WINDS ALONG THE BAJA COAST WILL REMAIN 
LIGHT. SOME SLIGHT INCREASE IN GAP WINDS THROUGH PAPAGAYO TO 20 
KT..OTHERWISE OTHER AREAS WILL CONTINUE TO HAVE LIGHT WINDS.
