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

BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
1500 UTC.

...SPECIAL FEATURES...

HURRICANE FAUSTO CENTERED NEAR 20.4N 116.8W...OR ABOUT 410 NM 
W-SW OF CABO SAN LUCAS MEXICO...AT 21/1500 UTC MOVING WNW AT 13 
KT. MAXIMUM SUSTAINED WIND SPEED IS 70 KT WITH GUSTS TO 85 KT. 
ESTIMATED MINIMUM CENTRAL PRESSURE IS 984 MB. SEE LATEST NHC 
FORECAST/ADVISORY UNDER AWIPS/WMO HEADERS MIATCMEP2/WTPZ22 KNHC 
FOR MORE DETAILS. FAUSTO APPEARS TO BE WEAKENING AS THE MID TO 
UPPER LEVEL CENTER IS BECOMING DECOUPLED FROM THE SURFACE 
CIRCULATION. NUMEROUS MODERATE TO ISOLATED STRONG CONVECTION IS 
WITHIN 150 NM NW SEMICIRCLE AND AND WITHIN 90 NM SE SEMICIRCLE 
OF CENTER. FAUSTO IS EXPECTED TO CONTINUE TO WEAKEN TO TROPICAL 
STORM WITHIN THE NEXT 12-24 HOURS.

THE 1007 MB LOW WAS UPGRADED TO TROPICAL DEPRESSION EIGHT-E AT 
21/1500 UTC. T.D. EIGHT-E IS CENTERED NEAR 13.4N 100.8W...OR 220 
NM SOUTH-SOUTHWEST OF ACAPULCO MEXICO AND ABOUT 400 NM  SOUTH 
SOUTHEAST OF MANZANILLO MEXICO MOVING W AT 12 KT. MAXIMUM 
SUSTAINED WIND SPEED IS 30 KT WITH GUSTS TO 40 KT. ESTIMATED 
MINIMUM CENTRAL PRESSURE IS 1006 MB. SEE LATEST NHC FORECAST/

...TROPICAL WAVES... 

NONE. 
  
...ITCZ...

ITCZ AXIS IS CENTERED FROM 06N76W TO 13N107W TO 7N125W TO TO 
10N140W. SCATTERED MODERATE TO STRONG CONVECTION WITHIN 150 NM 
OF COAST OF COSTA RICA AND NICARAGUA. SCATTERED MODERATE 
CONVECTION WITHIN 120 NM N OF ITCZ FROM 113W TO 118W. 
...DISCUSSION...

E OF 120W...
A STRONG UPPER LEVEL HIGH REMAINS CENTERED OVER S NEW MEXICO AND 
COVERS MUCH OF THE SW UNITED STATES AND N MEXICO...EXCEPT FOR A 
SMALL CUT-OFF LOW OVER THE RIO GRANDE VALLEY. THE MIDDLE AND 
UPPER LEVEL RIDGE EXTENDS EWD NEAR THE N COAST OF THE GULF OF 
MEXICO...AND THIS CONTINUES TO PRODUCE MAINLY DEEP-LAYERED 
EASTERLY FLOW OVER THE TROPICS E OF 110W. THE STEERING FLOW 
BECOMES MORE SOUTHEASTERLY BETWEEN 110W-120W AND IS ALLOWING 
HURRICANE FAUSTO TO TURN ON A NORTHWESTWARD COURSE. THIS FLOW 
ALSO CONTINUES TO PULL MOISTURE NWD THROUGH THE GULF OF 
CALIFORNIA AND FEEDING THE ONGOING NORTH AMERICAN SUMMER 
MONSOON. SHOWER/TSTM ACTIVITY HAS DECREASED OVER THE AREA BUT IS 
EXPECTED TO REDEVELOP LATER TODAY.

LARGE 8-9 FT SOUTHERLY SWELLS FROM HURRICANE FAUSTO...MIXED IN 
WITH SWELLS FROM SOUTHERN HEMISPHERE STORMS...CONTINUE TO REACH 
THE COAST OF MEXICO BETWEEN ACAPULCO AND THE BAJA PENINSULA S OF 
CABO SAN LAZARO. SOME OF THESE SWELLS ARE ALSO PUSHING INTO THE 
MOUTH OF THE GULF OF CALIFORNIA. LARGE BREAKING WAVES AND RIP 
CURRENTS WILL CONTINUE...ESPECIALLY ON S AND SW-FACING 
BEACHES...FOR THE NEXT 12-24 HOURS OR SO AND SLOWLY SUBSIDE OVER 
THE NEXT FEW DAYS.

W OF 120W...
THE REMNANT LOW OF T.D. ELIDA IS LOCATED W OF THE AREA NEAR 
17N143W MOVING W 10-15 KT WITH A CENTRAL PRESSURE OF 1010 MB. 
THE LOW CONTINUES TO PRODUCE ISOLATED SHOWERS/TSTMS WITHIN 90 
NM OF ITS CENTER. ELSEWHERE...A LARGE CUT-OFF LOW IS CENTERED W 
OF N CALIFORNIA NEAR 40N127W WITH A TRAILING TROUGH REACHING S 
ALONG A LINE THROUGH 32N129W TO A SMALL CYCLONIC CIRCULATION 
NEAR 25N130W CONTINUING TO 18N140W. THE AREA WEST OF 120W IS DRY 
AND CLOUD FREE IN THE MIDDLE AND UPPER LEVELS DUE TO MODERATE TO 
STRONG SUBSIDENCE WITH A OVERCAST STRATOCUMULUS FIELD N OF 15N.
