What happened
After crossing Cuba, Cleo turned north toward the lower east coast of Florida, and the edge of its eye moved onto Key Biscayne at 2 a.m. EST on August 27, 1964.1 NHC's best track puts the landfall at 0800 UTC that day as a Category 2 hurricane with 95-knot (109 mph) winds and a central pressure of 968 mb.2 The Weather Bureau estimated sustained winds of 100 to 105 mph with gusts to 135 mph.1 Cleo left Florida between St. Augustine and Jacksonville and came back ashore on the Georgia coast as a tropical storm on August 29.3,2
Major damage hit a strip 20 to 35 miles wide along Florida's east coast from Miami to about Melbourne.1 Storm surge stayed under 4 feet in the Miami area but reached 5 feet above normal at Fort Lauderdale and 5 to 6 feet above normal at Pompano Beach.3 Buildings in Dade and Broward counties had little structural damage.3 Most of the damage there was broken glass in unprotected storefronts and in Miami Beach hotels and motels, many of which took in water once their windows broke.3 The Weather Bureau estimated Florida property damage at $112.5 million, about $125 million with indirect costs, and reported no deaths in Florida.3
Nine or more tornadoes were reported in Florida and the Carolinas.3 One at Laurinburg, North Carolina, on August 29 injured 15 people and caused $250,000 in damage.4 Parts of Tidewater Virginia got 10 to 14 inches of rain in about 12 hours, and NOAA lists 2 deaths and $3 million in damage in Virginia.5
