TROPICAL STORM IRWIN WIND SPEED PROBABILITIES NUMBER  24            
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP102017               
0900 UTC FRI JUL 28 2017                                            

AT 0900Z THE CENTER OF TROPICAL STORM IRWIN WAS LOCATED NEAR        
LATITUDE 14.9 NORTH...LONGITUDE 124.8 WEST WITH MAXIMUM SUSTAINED   
WINDS NEAR 45 KTS...50 MPH...85 KM/H.                               

Z INDICATES COORDINATED UNIVERSAL TIME (GREENWICH)                  
   PACIFIC  DAYLIGHT TIME (PDT)...SUBTRACT 7 HOURS FROM Z TIME      
   HAWAIIAN STANDARD TIME (HST)...SUBTRACT 10 HOURS FROM Z TIME     

WIND SPEED PROBABILITY TABLE FOR SPECIFIC LOCATIONS                 

CHANCES OF SUSTAINED (1-MINUTE AVERAGE) WIND SPEEDS OF AT LEAST     
   ...34 KT (39 MPH... 63 KM/H)...                                  
   ...50 KT (58 MPH... 93 KM/H)...                                  
   ...64 KT (74 MPH...119 KM/H)...                                  
FOR LOCATIONS AND TIME PERIODS DURING THE NEXT 5 DAYS               

PROBABILITIES FOR LOCATIONS ARE GIVEN AS OP(CP) WHERE               
    OP  IS THE PROBABILITY OF THE EVENT BEGINNING DURING            
        AN INDIVIDUAL TIME PERIOD (ONSET PROBABILITY)               
   (CP) IS THE PROBABILITY OF THE EVENT OCCURRING BETWEEN           
        06Z FRI AND THE FORECAST HOUR (CUMULATIVE PROBABILITY)      

PROBABILITIES ARE GIVEN IN PERCENT                                  
X INDICATES PROBABILITIES LESS THAN 1 PERCENT                       
PROBABILITIES FOR 34 KT AND 50 KT ARE SHOWN AT A GIVEN LOCATION WHEN
THE 5-DAY CUMULATIVE PROBABILITY IS AT LEAST 3 PERCENT.             
PROBABILITIES FOR 34...50...64 KT SHOWN WHEN THE 5-DAY              
64-KT CUMULATIVE PROBABILITY IS AT LEAST 1 PERCENT.
