in the REMARKS section of the next transmitted 

 report to be sent via longline teletype. 



When wind meets the criteria for variable 

 wind, the contraction "WND" will be entered 

 in column 13 followed by the extremes of 

 variability and separated by the letter 

 •'V" (e.g., WND 32V05). 



WIND SUMMARY DATA (COLS 71, 72 

 & 73). — A column 71 entry Is only made at 



stations having a continuous instantaneous wind- 

 speed recorder. Enter in knots the highest 

 instantaneous peak gust recorded during the 

 24 hours ending at midnight. Column 72 is for 

 entry of the peak gust's direction to the nearest 

 10 degrees. If the direction portion of the 

 record is missing or inoperative, estimate from 

 the column 9 entries and enter to the 8 point 

 compass. Column 73 is for the time of oc- 

 currence of the maximum gust and is entered 

 to the nearest minute LST.
