This Date in Weather History

1900 - The greatest weather disaster in U.S. records occurred when a hurricane struck Galveston TX. A tide fifteen feet high washed over the island demolishing or carrying away buildings, and drowning more than 6000 persons. The hurricane destroyed more than 3600 houses, and total damage was more than thirty million dollars. Winds to 120 mph, and a twenty foot storm surge accompanied the hurricane. Following the storm, the surf was three hundred feet inland from the former water line. The hurricane claimed another 1200 lives outside of the Galveston area.
