1921 Tampa Bay hurricane [SEP] Introduction
The storm left two additional fatalities in St. Petersburg. A number of streets in Tarpon Springs were littered with masses of debris, with many structures and trees suffering extensive damage. Southward in Manatee County and Sarasota County, many waterfront communities along Sarasota Bay and the Gulf of Mexico, such as Cortez and Sarasota, suffered heavy structural losses. Strong winds occurred as far east as the Atlantic coast of the state, though wind damage east of the Tampa Bay area was generally limited to downed trees and power lines, resulting in power outages, particularly in Orlando. Agriculture throughout the state experienced significant impact as well, including over $2 million (equivalent to $ million in ) in damage and the loss of at least 800,000 boxes of citrus crops alone.
