800 AM PDT TUE SEP 19 2017  
 
OTIS HAS BEEN DEVOID OF DEEP CONVECTION FOR ABOUT 10 HOURS, AND  
THE CYCLONE ONLY CONSISTS OF A COMPACT SWIRL OF LOW-LEVEL CLOUDS.  
THEREFORE, OTIS IS NOW CLASSIFIED AS A REMNANT LOW, AND THIS IS  
LAST ADVISORY ISSUED BY THE NATIONAL HURRICANE CENTER. ASCAT DATA  
FROM LAST NIGHT INDICATED THAT MAXIMUM WINDS WERE NEAR 35 KT.  
ASSUMING SOME SPIN DOWN SINCE THAT TIME DUE TO THE LOSS OF DEEP  
CONVECTION, THE INITIAL WIND SPEED IS LOWERED TO 30 KT. CONTINUED  
WEAKENING DUE TO COOL SSTS AND DRY AIR IS EXPECTED, AND OTIS IS  
EXPECTED TO DISSIPATE IN A DAY OR SO.  
 
THE REMNANT LOW HAS TURNED TO THE WEST IN THE LOW-LEVEL TRADE WIND  
FLOW. A WEST TO WEST-SOUTHWEST MOTION IS EXPECTED UNTIL THE SYSTEM  
DISSIPATES.
