English: When Hurricane Agnes made landfall in Florida on June 18, 1972, it quickly became the costliest natural disaster to ever hit the U.S up to that time. Seen here from the ATS-3 satellite before moving ashore, Agnes eventually tracked up the Eastern Seaboard and dumped record amounts of rainfall in the Northeast and Mid-Atlantic. All told, there were 122 deaths reported nationwide as a result of the flooding and rainfall caused by Hurricane Agnes. Total damage from the storm was estimated to cost more than $3 billion.
