Según el JTWC todavía no es categoría 5, pero casi casi, porque en el boletín de discusión último que hay publicado le dan una intensidad de 135 KT... A partir de 137 sería categoría 5 
SUPER TYPHOON (STY) 17W (SANBA), LOCATED APPROXIMATELY 600 NM
SOUTH OF KADENA, OKINAWA, JAPAN, HAS TRACKED NORTHWARD AT 07 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY (EIR) REVEALS A PERSISTENT 20 NM EYE COMPLETELY ENCIRCLED
BY A THICK RING OF DEEP CONVECTION WITH NO BANDING OUTSIDE OF THIS
RING, CONSISTENT WITH AN ANNULAR TYPHOON. A 130903Z SSMIS 91 GHZ
MICROWAVE IMAGE SUPPORTS THIS BY SHOWING A VERY SYMMETRIC SYSTEM
WITH AN EYE SURROUNDED BY DEEP CONVECTION AND SOME DISPLACED
CONVECTION IN THE SOUTHERN SEMI-CIRCLE. THE CURRENT POSITION IS
BASED ON THE EYE IN THE AFOREMENTIONED IMAGERY WITH HIGH
CONFIDENCE. ANIMATED WATER VAPOR IMAGERY CONTINUES TO INDICATE
EXCELLENT OUTFLOW WITH A POINT SOURCE ANTICYCLONE LOCATED OVER THE
SYSTEM. FURTHER UPPER LEVEL ANALYSIS REVEALS THAT LOW (05 TO 10
KNOTS) VERTICAL WIND SHEAR CONTINUES TO ACT UPON THE SYSTEM.
INITIAL INTENSITY OF 135 KNOTS IS BASED ON AVERAGE OF DVORAK
ESTIMATES OF 127 TO 140 KNOTS FROM KNES, RJTD AND PGTW,
RESPECTIVELY. STY 17W SHOULD MAINTAIN INTENSITY AS IT HAS BECOME
ANNULAR FOR THE NEXT 24 TO 36 HOURS AND THE UPPER LEVEL ENVIRONMENT
REMAINS FAVORABLE. SEA SURFACE TEMPERATURES ARE ALSO FORECASTED TO
REMAIN FAVORABLE (29-30 DEGREES CELSIUS) AS STY 17W STEERS NORTH.
