Was Typhoon “Louise” in October 1945 attracted by naval activities?

The Pacific War ended with the Japanese surrender on 14th August 1945. But a huge battle force was still in the western Pacific in early October 1945, which had been gathered for the Invasion of Japan in November. Had previous and ongoing activities at sea off the shores of Japan attracted the Typhoon “LOUISE” to make a sharp turn suddenly?

[Extract on the Typhoon from Commander in Chief, Pacific Fleet, (1)]. On Oct. 4, a typhoon developed in the Caroline Islands and was named "Louise".  It was expected to move northwest into the East China Sea, however the storm suddenly veered sharply to the right and headed for Okinawa.  The forecast was for winds of 60 knots, with 90 knot gusts. "'Louise', however, failed to conform to pattern, and that evening, as it reached 25 degrees N (directly south of Okinawa) it slowed to six knots and greatly increased in intensity.  As a result, the storm which struck in the afternoon of the 9th has seldom been paralled in fury and violence...."

[Extract (2)]. Navy Meteorologists expected it to pass between Formosa and Okinawa, and to disappear into the East China Sea. On the evening of October 8th, the storm changed direction and abruptly veered to the east. When it did so, there was insufficient warning to allow the ships in the harbor (at Buckner Bay, on the east coast of the island of Okinawa) to get under way in order to escape the typhoon. By late morning on the 9th, rain was coming down in floods and torrents and the seas were rising visibility zero. Winds 80 miles per hour began blowing from the east and northeast by early afternoon, the wind had risen to over 100 miles per hour, the rain coming in horizontally and the larger vessels began dragging anchor under the pounding of 50 foot seas. Buckner Bay  became a scene of devastation. Gigantic waves swamped small vessels and engulfed larger ones. Victory ships were swept off the decks by 60 foot waves that reached the tops of the masts of their vessels.

The toll on ships was staggering. Almost 270 ships were sunk, grounded or damaged beyond repair. Fifty-Three ships in too bad a state to be restored to duty were decommissioned, stripped and abandoned.
