This Date in Weather History

1961 - Very large and slow moving Hurricane Carla made landfall near Port Lavaca TX. Carla battered the central Texas coast with wind gusts to 175 mph, and up to 16 inches of rain, and spawned a vicious tornado which swept across Galveston Island killing eight persons. The hurricane claimed 45 lives, and caused 300 million dollars damage. The remnants of Carla produced heavy rain in the Lower Missouri Valley and southern sections of the Upper Great Lakes Region.
