This Date in Weather History

1960 - Hurricane Donna struck the Florida Keys, with winds gusting to 180 mph and a thirteen foot storm surge. The hurricane then moved north along the eastern coast of Florida and inundated Naples before moving out to sea. Hurricane Donna claimed fifty lives, injured 1800 others, and caused more than 300 million dollars damage. The Marathon/Tavernier area was almost completely destroyed, and in the Citrus Belt, most of the avacado crop was blown from the trees. Hurricane Donna wreaked havoc from Florida to Maine, with wind gusts to 100 mph along much of the coast. Hurricane Donna produced wind gusts to 121 mph at Charleston SC on the 11th, and wind gusts to 138 mph at Blue Hill Observatory MA on the 12th. The hurricane finally died over Maine two days later, producing more than five inches of rain over the state.
