The depression strengthened to a tropical storm one day later, and it received the name Charlotte from the Joint Typhoon Warning Center (JTWC).

Large amounts of rainfall caused landslides across the islands and many rice and sugar cane crops were destroyed by floods.

The low pressure intensified and contracted by October 8, and a closed circulation was found later that day by a reconnaissance aircraft.

[1] Both Japan Meteorological Agency (JMA) and Joint Typhoon Warning Center (JTWC) began tracking the system as a tropical depression on October 9,[2][3][nb 1] with winds of 50 km/h (30 mph),[3] and a surface pressure of 1,008 hectopascals (29.8 inHg).

[5] The storm reached peak strength at 1200 UTC on October 13, with winds of 265 km/h (165 mph) and a pressure of 905 hPa (26.7 inHg) recorded by a reconnaissance aircraft.

A secondary upper level center north of Charlotte was found by a reconnaissance aircraft, which used it for fixes during that day.

[2] The cyclone was embedded in the polar front hours later,[1] and JTWC ceased tracking the system after it weakened past tropical storm strength at 55 km/h (35 mph) at 1800 UTC.

[6] On October 17, twelve freighters sought shelter in the harbor at Kagoshima, and seventy small craft moved to other protected areas within Japan.

[9] A large fleet of British ships, led by HMS Alert, arrived at Yokohama after being delayed by typhoons Charlotte and Dinah.

[12] Winds of 90–150 miles per hour (140–240 km/h) and rainfall of 24 inches (61 cm) were reported on the island,[13][1] This resulted in landslides, exacerbated by deforestation, to happen across northern Okinawa.

Lieutenant General Donald Prentice Booth issued a statement of condolence to the Okinawan families after the storm.
