[3] At 00:00 UTC of October 2, the Fleet Weather Center noted that a tropical depression was developing near the Caroline Islands as a result of an equatorial outflow.
[6] On October 7, Louise started to accelerate, with the Fleet Center forecasting that the storm may continue its northwestward trend and make landfall in Formosa; however, a high-pressure near the Philippines turned the system to the north, threatening Okinawa.
[5] Early the next day, the system strengthened to a minimal typhoon as it started to enter the East China Sea and impact the Nansei Islands.
[4] It held its intensity for 21 hours until it weakened back to a tropical storm later that night as it started to curve towards the west, approaching the Japanese archipelago.
[4][5] A combination of unfavorable conditions and a plume of cold air further weakened Louise before making landfall somewhere near Akune in Kagoshima Prefecture on October 10.
[1] Louise had a devastating effect on Japan, with casualties including at least 377 persons dead, 202 injured, and 74 missing,[1] and contemporaneous reports estimated over 500 fatalities, with most occurring in the Nansei Islands.
[12] On a longer scale, Japan’s war efforts had caused significant overlogging, which produced erosion-induced river flooding and the loss of intertidal forests which would have otherwise served as a storm buffer.
[16] Okinawa prefecture was occupied by the United States military following the end of World War II, and the U.S. Navy incurred significant losses during the storm.
