NWS NATIONAL HURRICANE CENTER MIAMI FL                         
1605 UTC WED SEP 09 2015

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 
1530 UTC.               
   
...SPECIAL FEATURES...

HURRICANE LINDA WAS CENTERED NEAR 24.2N 116.9W 979 MB AT 1500 
UTC SEP 09 MOVING NW OR 325 DEG AT 11 KT. MAXIMUM SUSTAINED 
WINDS 70 KT GUSTS 85 KT. NUMEROUS MODERATE TO STRONG CONVECTION 
IS OCCURRING WITHIN 45 NM NW AND 20 NM SE SEMICIRCLES... WHILE 
SCATTERED MODERATE CONVECTION IS ELSEWHERE FROM 23.5N TO 25.5N 
BETWEEN 116W AND 118W. THIS CONVECTION ASSOCIATED WITH LINDA 
CONTINUES TO DIMINISH DRASTICALLY FROM 24 HOURS AGO AS THE 
HURRICANE MOVES OVER PROGRESSIVELY COOLER WATERS AND INTO A 
DRIER MORE STABLE AIRMASS. CONTINUED WEAKENING IS EXPECTED WITH 
LINDA AS IT MOVES NORTHWESTWARD FOR THE NEXT DAY OR TWO...AND IS 
EXPECTED TO BECOME A NON TROPICAL REMNANT LOW PRESSURE SYSTEM 
WITHIN 48 HOURS. SOUTHERLY SWELL GENERATED FROM LINDA CONTINUES 
TO BATTER THE WEST COAST OF BAJA CALIFORNIA WITH LARGE AND 
DANGEROUS SURF...AND HAS BEGUN TO GRADUALLY SPREAD INTO THE 
WATERS OF SOUTHERN CALIFORNIA THIS MORNING. THESE SWELL WILL 
CONTINUE TO PRODUCE LARGE AND POWERFUL SURF AND CREATE LIFE-
THREATENING RIP CURRENT CONDITIONS ALONG THE BAJA CALIFORNIA 
COASTLINE...WHILE SURF CONDITIONS GRADUALLY DETERIORATE ACROSS 
SOUTHERN CALIFORNIA THIS AFTERNOON THROUGH TONIGHT. REFER TO THE 
LAST NHC FORECAST/ADVISORY UNDER AWIPS/WMO HEADERS 
MIATCMEP5/WTPZ25 KNHC FOR ADDITIONAL DETAILS. 

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...            

THE MONSOON TROUGH EXTENDS FROM 8N81W TO 9N100W THEN RESUMES 
FROM 15N122W TO 9N140W. SCATTERED MODERATE TO STRONG CONVECTION 
NOTED WITHIN 240 NM S OF AXIS E OF 83W AND WITHIN 280 NM N OF 
AXIS FROM 86W TO 96W AND FROM 8N-13N BETWEEN 112W-133W.

...DISCUSSION...

MODERATE TO LOCALLY FRESH N TO NE WINDS PREVAIL OVER THE 
REMAINDER OF THE AREA W OF OF LINDA...GENERATED BY ANTICYCLONIC 
FLOW AROUND A 1024 MB HIGH CENTERED NEAR 40N140W. SEAS ACROSS NW 
PORTIONS ARE CURRENTLY RUNNING 5-7 FT IN MIXED SWELL AND WILL 
SUBSIDE SLIGHTLY DURING THE NEXT 24 HOURS. 

ELSEWHERE...LINDA HAS MOVED SUFFICIENTLY NORTHWARD OUT OF THE 
TROPICS AND COMPLETELY SEVERED FROM THE EASTERN PACIFIC MONSOON 
TROUGH. THE MONSOON TROUGH HERE HAS BEGUN TO RE-ESTABLISH ACROSS 
THE TROPICAL EASTERN PACIFIC...WHERE CONVECTION DESCRIBED ABOVE 
HAS BECOME VERY ACTIVE. COMPUTER MODEL GUIDANCE SUGGESTS THAT 
CONVECTION WILL REMAIN VERY ACTIVE NEAR AND S OF THE MONSOON 
TROUGH W OF 100W THROUGH THU.
