As a developing tropical cyclone, Betsy tracked over the northern Leeward Islands, producing moderate gusts and slight rainfall, though only minimal damage was reported. After tracking over open waters for several days, Betsy had significantly strengthened upon moving through the Bahamas. There, considerable damage occurred, particularly to crops on the archipelago's islands. For the island chain, Betsy was considered the worst hurricane since a tropical cyclone impacted the region in 1929. Widespread power outage and property damage ensued due to the storm's strong winds. Overall, damage on the Bahamas amounted to at least $14 million, and one fatality occurred. From there Betsy tracked westward and made landfall on southern Florida, where it was considered the worst tropical cyclone since a hurricane in 1926. Betsy's strong storm surge inundated large portions of the Florida Keys, flooding streets and causing widespread damage. The only route out of the Keys onto the mainland was cut off by the storm. In the state alone, Betsy caused $139 million in damage and five deaths.
