No other change was maie in the previous # minus 18 Hour advisorye At the QLOGM Command Briefing the forecast winds for H-Hour were east northeast and light in the lower levels turning around counterclockwise with increasing altitude, but light enough that resultant wind speeds in the direc tion of NAN and TASE were very low. West southwest to southwest winds were forecast between 15,000 amd 50,000, westerlies from 50,000 to 60,000, and easterlies above. The radsafe situation was recommended as favorable except for the light resultant winds toward the south, In view of the latter situa— tion, a recommendation was made to move the taske force ships out te a point 50 NM southeast of GZ, except for those ships required to be in closer for orerational reasons. No transient ships were know to be in, om approaching, the H-eHour fall-out pattern, The decision was made to shoct on schedule and to mowe the fleet as recommended except that ships required to be close-in for operational reasons would move south immediately after H-tiour, It was also decided to make a further weather/radsafe check at O400M. The forecast fall-out plot by elliptical approximation is included in Inel 4. The new technique, based on forecast time and space changes in the wind rattern for H to H A# 2% hours, save a similar fall-out pattern except that its major axis lay more along an east to east northeast line from GZ than northeast as given by the above plot, Based on the midnight forecast H-iiour winds, the surface and air RADEXES were modified as follows: Surfice RiDEX: Trué@ bearings from GZ: 240° clockwise to 270° radial distance 75 NM Nod
