Tropical Storm Eta passed northwest through the middle Florida Keys on November 8 through 9, 2020.  Primary impacts from wind occurred as result of a primary rain band which drifted very slowly north through the Upper Florida Keys.  Peak wind gusts were mostly in the 50 to 60 mph range, downing trees and large tree limbs, utility lines, and a billboard. One residence was destroyed by a fallen tree resulting in 1 minor injury. Two other residential structures were significantly damaged, with three inaccessible  due to blocked streets. About 20 separate power outages affected about 1,000 customers, mostly in Key Largo. Storm Surge flooding was generally in the 1.5 to 2.5 foot range, producing significant street flooding in oceanside Key Largo neighborhoods.  The northbound right-of-way was damaged including major erosion, loss of riprap, and about 3,000 feet of fencing along northbound U.S. Highway 1 along the west end of Barnes Sound and Manatee Bay.  Minor overwash occurred in the middle Florida Keys at Key Colony Beach, along with yard and dock flooding along the Florida Bay side of Marathon. Widespread rainfall of 3.5 to over 8 inches was measured throughout the Keys, with the highest totals in Key Largo.  Damages were estimated near $500K due to mostly from homes damaged by falling trees and tree limbs, as well as utility damage. Storm Surge damage near $100K due to wave action on top of a minor storm surge to the U.S Highway 1 right-of-way.
