This Date in Weather History

1944 - Typhoon Cobra, also known as the Typhoon of 1944 or Halsey's Typhoon, was the United States Navy designation for a tropical cyclone that struck the Task Force 38 in the during World War II in the Pacific. The typhoon was first observed on December 17 as it surprised a fleet of ships in the open waters of the western Pacific Ocean. Sustained winds associated with the storm were up to 100 mph with gusts to 140 mph. On December 18, the small but violent typhoon hit the Task Force while many of the ships were attempting to refuel. Due to the extreme seas and winds, three destroyers capsized and went down with practically all hands, while a cruiser, five aircraft carriers, and three destroyers suffered serious damage. Approximately 790 officers and men were lost or killed with another 80 injured. This storm inflicted more damage on the Navy than any storm since the hurricane at Apia, Samoa, in 1889.
